Am I correct in saying that the Search function uses a JSON feed and RSS uses a JSON feed, has anyone managed to modify/create a new search function for BT which utilises a RSS feed. I have a PHP script which delivers my RSS feed from a remote site and I would like to search this using the search function, I hope this makes sense. I think this facility would be useful to a lot of BT enthusiasts :-)

Hmm... I think I understand your question. There are a few approaches to this. The idea is to 'post' the value in the search box in the mobile app the .PHP script before outputting the RSS data. The 'top' of the script grabs the value entered (it's appended to the end of the dataURL) then queries database or whatever then builds the RSS output. This means you'll need a way to: a) Append the entered value to the end of the dataURL before 'refreshing' b) Grabbing the value and building the results Appending the value and making the request are not part of the existing BT_screen_menuSearch.m file. But, lots and lots of the code is the same as the BT_screen_menuList.m file. This menuList file does request it's data from a URL. This means you could look at these two files and try to understand the differences then add a few methods in the search screen to faciliate the search. Techie? Totally. Doable? Yup. Just take some patience.

I was thinking initially the RSS Feed might be a small list which would display in full as the RSS Feed does now and as with the RSS Search starts with a full list as you type in to the Search bar above it narrows the results. This would literally be a like for like as regards functionality, just wondering how to get the search to use thee RSS feed instead of the menu list. Your idea is great it takes it to another level, just trying to crawl before I can run so to speak.

Ah...yes, makes sense. Something like this: RSS feed reads data. While it's reading the data, it 'builds' an array of titles to search. Next, a search box is used for the title bar. Next, the search box searches in the 'built' array of titles to narrow the list. A matter of combining the existing logic into a new and improved RSS screen.m. If you feel like tackling it, we'de be happy to add it to the list of things to add. As easy as it may be for us to do on this end, we have WAY to many things going on (Android is killing us!) to do it here until we get this darned list narrowed down. The list of to-do's is longer today than ever! LOL. So...see if you can a) Declare a new array property in the .h file (this is the existing RSS screen) b) Init this array in the .m to an 'empty array' This is a (NSMutableArray) b) Fill this array of title while the RSS feed is being parsed c) Add the search bar to the title (See how it's done in the search screen code, it's calling a function in the BT_layout.m file to fetch the navigation bar with the title) d) Add the search method declarations in the .h file, and the actual methods in the .m file (these will be nearly the same as the search screen) Little gotchas like adding the delegate methods for text boxes, etc. may hang you up. It's not too tough but may frustrate you trying? The idea is that the search function would rebuild the list as the title is searched, exactly like it does in the exisiting search screen.

Many thanks I'll give it a go, if I get it working I'll send you the files :-)

Ok, I've got declared new arrays in BT_screen_rssReader.h NSMutableArray *externalItems; UITextField *searchBox; NSTimer *searchTimer; BOOL isSearching; @property (nonatomic, retain) NSMutableArray *externalItems; @property (nonatomic, retain) UITextField *searchBox; @property (nonatomic, retain) NSTimer *searchTimer; @property (nonatomic) BOOL isSearching; In BT_screen_rssReader.h I have the following code: @synthesize externalItems, searchBox, searchTimer, isSearching; //view will appear -(void)viewWillAppear:(BOOL)animated{ [super viewWillAppear:animated]; [BT_debugger showIt:self:@viewWillAppear]; //flag this as the current screen *****_appDelegate *appDelegate = (*****_appDelegate *)[[UIApplication sharedApplication] delegate]; appDelegate.rootApp.currentScreenData = self.screenData; //setup navigation bar and background [BT_viewUtilities configureBackgroundAndNavBar:self:[self screenData]]; //custom view for title so we can insert a search bar UIView *titleView = [[[UIView alloc] initWithFrame:CGRectMake(0, 0, 235, 40)] autorelease]; [titleView setTag:88]; titleView.backgroundColor = [UIColor clearColor]; //left view for search box UIImageView *searchImgView = [[[UIImageView alloc] initWithImage:[UIImage imageNamed:@search.png]] autorelease]; //search hint... NSString *searchHint = NSLocalizedString(@search, search...); if(![[BT_strings getStyleValueForScreen:self.screenData:@searchHint:@] isEqualToString:@]){ searchHint = [BT_strings getStyleValueForScreen:self.screenData:@searchHint:@]; } //if we already searched reset the search hint (happens when coming back to this screen) NSString *searchText = @; if([[BT_strings getPrefString:@currentSearchValue] length] > 0){ searchText = [BT_strings getPrefString:@currentSearchValue]; } //searchBar in title view searchBox = [[[UITextField alloc] initWithFrame:CGRectMake(0, 5, 210, 30)] autorelease]; searchBox.clearButtonMode = UITextFieldViewModeAlways; searchBox.tag = 199; searchBox.text = searchText; searchBox.placeholder = searchHint; searchBox.contentVerticalAlignment = UIControlContentVerticalAlignmentCenter; searchBox.textAlignment = UITextAlignmentLeft; searchBox.textColor = [UIColor blackColor]; searchBox.font = [UIFont systemFontOfSize:14]; searchBox.keyboardType = UIKeyboardTypeDefault; searchBox.borderStyle = UITextBorderStyleRoundedRect; searchBox.autocorrectionType = UITextAutocorrectionTypeNo; searchBox.autocapitalizationType = UITextAutocapitalizationTypeNone; searchBox.keyboardAppearance = UIKeyboardAppearanceAlert; searchBox.leftViewMode = UITextFieldViewModeAlways; searchBox.returnKeyType = UIReturnKeyDone; searchBox.leftView = searchImgView; searchBox.delegate = self; [searchBox addTarget:self action:@selector(textFieldDidChange:) forControlEvents:UIControlEventEditingChanged]; [titleView addSubview:searchBox]; self.navigationItem.titleView = titleView; //if we have not yet inited data.. if(self.didInit == 0){ [self performSelector:(@selector(loadData)) withObject:nil afterDelay:0.1]; } //show adView? if([[BT_strings getJsonPropertyValue:self.screenData.jsonVars:@includeAds:@0] isEqualToString:@1]){ [self showHideAdView]; } } I commented out the previous viewWillAppear so now I have an RSS Screen with Search Bar, no errors but I'm struggling with the hard part, shocker I know LOL. Now suffering from Can't see the wood for the trees syndrome, any pointers you can give me? And yes I realise I'm pushing things now :-)

You're not pushing anything...no worries. Lets figure out how far you got and where you are now. So, if you have a screen setup, with the search bar, awesome. The next part will be to get the methods implemented that actually do the search. Baby steps I guess. It doesn't sound like you've told your RSS class file (BT_screen_rssReader) how to handle the interactions with the search/text entry box. Handles the interactions is done with 8 methods. textFieldDidBeginEditing textFieldDidEndEditing textFieldShouldBeginEditing textFieldShouldEndEditing textFieldShouldReturn textFieldShouldClear textFieldDidChange This means you'll need to get these methods created in the BT_screen_rssReader.m file. You can copy-n-paste the same methods from the BT_screen_menuSearch.m file. After doing that, have a look at each mehod, it's self explanatory for the most part. Each methods name suggests what interactions it handles. Look at the methods, one by one and try to understand how they call other methods. The textFieldDidChange method is where you'll have the most trouble ( I think ). This is where the array of values assigned to the list changes based on the searches. Your new array is called: externalItems. Maybe re-name it to filteredMenuItems so it matches the name of the array used in the textFieldDidChange method. This is the array you will fill with your values from the RSS feed. See if you can get this far without erros.

Ok, this should give you a giggle. Baby Steps, I might need Pre-Birth Steps LOL :) Ok, despite having no errors yesterday in Xcode, if I ran the app and clicked in the text box I triggered the appDelegate function which halted the app, not surprisingly as the code wasn't complete. I have made a little headway, I have added the code you suggested, tried to do a little digging as to an error relating to: searchBox.delegate = self; which turned out to be the lack of declaration of UITextFieldDelegate for the BT_screen_rssReader : BT_viewController. I currently have the following error: BT_screen_rssReader.m: warning: Semantic Issue: Instance method '-textFieldDidChange:' not found (return type defaults to 'id') which relates to: [self textFieldDidChange:NULL]; Please see amendments commented as //Going-Viral below and any tips you can give I would be much appreciated, apologies for removing the disclaimer for both files, this is just for purposes of this post as I did't want this thread to turn in to War & Peace so to speak: #import <Foundation/Foundation.h> #import <UIKit/UIKit.h> #import BT_viewController.h #import BT_item.h #import BT_header_image_view.h #import BT_rssParser.h #import BT_downloader.h @interface BT_screen_rssReader : BT_viewController <UITableViewDelegate, BT_downloadFileDelegate, BT_rssParserDelegate, UITableViewDataSource, //Added Going-Viral UITextFieldDelegate, // UIScrollViewDelegate>{ NSMutableArray *menuItems; //Added Going-Viral NSMutableArray *filteredMenuItems; NSMutableArray *displayMenuItems; // NSArray *rssItems; UITableView *myTableView; BT_header_image_view *headerImageView; BT_downloader *downloader; NSString *saveAsFileName; BOOL isLoading; NSOperationQueue *queue; int didInit; //Added Going-Viral UITextField *searchBox; NSTimer *searchTimer; BOOL isSearching; // element names for parser */ NSString *xmlItemTagName; NSString *xmlItemTitleName; NSString *xmlItemDescriptionName; NSString *xmlItemLinkName; NSString *xmlItemImageName; NSString *xmlAppendValueToLinkURL; } @property (nonatomic, retain) NSMutableArray *menuItems; //Added Going-Viral @property (nonatomic, retain) NSMutableArray *filteredMenuItems; @property (nonatomic, retain) NSMutableArray *displayMenuItems; // @property (nonatomic, retain) NSArray *rssItems; @property (nonatomic, retain) UITableView *myTableView; @property (nonatomic, retain) BT_header_image_view *headerImageView; @property (nonatomic, retain) NSString *saveAsFileName; @property (nonatomic, retain) BT_downloader *downloader; @property (nonatomic) BOOL isLoading; @property (nonatomic) int didInit; //Added Going-Viral @property (nonatomic, retain) UITextField *searchBox; @property (nonatomic, retain) NSTimer *searchTimer; @property (nonatomic) BOOL isSearching; // @property (nonatomic, retain) NSOperationQueue *queue; @property (nonatomic, retain) NSString *xmlItemTagName; @property (nonatomic, retain) NSString *xmlItemTitleName; @property (nonatomic, retain) NSString *xmlItemDescriptionName; @property (nonatomic, retain) NSString *xmlItemLinkName; @property (nonatomic, retain) NSString *xmlItemImageName; @property (nonatomic, retain) NSString *xmlAppendValueToLinkURL; -(void)headerImageTap; -(void)loadData; -(void)downloadData; -(void)layoutScreen; -(void)parseScreenData:(NSString *)theData; -(void)checkIsLoading; @end BT_screen_rssReader.m #import <UIKit/UIKit.h> #import <Foundation/Foundation.h> #import <CFNetwork/CFNetwork.h> #import JSON.h #import *****_appDelegate.h #import BT_fileManager.h #import BT_color.h #import BT_strings.h #import BT_viewUtilities.h #import BT_downloader.h #import BT_item.h #import BT_debugger.h #import BT_viewControllerManager.h #import BT_cell_menuList.h #import BT_header_image_view.h #import BT_rssParser.h #import BT_rssItem.h #import BT_screen_rssReader.h @implementation BT_screen_rssReader //Modified Going-Viral @synthesize menuItems, filteredMenuItems, displayMenuItems, rssItems, myTableView, didInit; @synthesize saveAsFileName, downloader, isLoading, headerImageView, queue; @synthesize xmlItemTagName, xmlItemTitleName, xmlItemDescriptionName, xmlItemLinkName, xmlItemImageName; @synthesize xmlAppendValueToLinkURL; @synthesize searchBox, searchTimer, isSearching; //viewDidLoad -(void)viewDidLoad{ [BT_debugger showIt:self:@viewDidLoad]; [super viewDidLoad]; //init screen properties [self setDidInit:0]; //flag not loading [self setIsLoading:FALSE]; //appDelegate *****_appDelegate *appDelegate = (*****_appDelegate *)[[UIApplication sharedApplication] delegate]; //////////////////////////////////////////////////////////////////////////////////////// //build the table that holds the menu items. self.myTableView = [BT_viewUtilities getTableViewForScreen:[self screenData]]; self.myTableView.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight; [self.myTableView setDataSource:self]; [self.myTableView setDelegate:self]; //prevent scrolling?

Myterious. You could try declaring (some call this describing, or interfacing) the Text Field Methods you have in the .m file. You do this in the .h file. There should be a few methods already described in the .h file. This sometimes helps the compiler understand that you've added method to the .m file. Confusing for sure but worth a shot. If the RSS class is not implementing the UITextFieldDelgate protocol (it is) then the methods should fire when you interact with the search box. I'm thinking this will cure the Symantec issue and we'll see what other issues exist after that.

Will have another look, I'm new to Objective-C, not programming, but this language is something else. Just hoping I get a space on a course for Objective-C and Cocoa soon :-)

Ok, I got rid of the wood for the tree scenario, took a step back and start again. This time I have got all elements added yet this time with no errors. The app loads, doesn't crash, displays the search bar and allows me to type into the search bar without the appDelegate function kicking in. I'm guessing now, that the reason the search functionality isn't working is that the search box isn't binding to the RSS feed. Could you please nudge me in the right direction?
