Today I created code that made a single button turn the ios light on and off. That is all.

Nicely done. Good stuff.

Do you mean the flash on the rear of the iPhone 4, 4S, 5 or iPod Touch 5th Gen? Because if so, well done! It really is a good seller that type of app.

yup. I think I might start a buzztouch blog two actually "what I did today" & "What I should have done today"

I'd be interested in seeing that code if you want to share! Can you make the light blink at specified intervals? Somebody earlier was looking for an app they could use to tune things with various RPMs. Mark

@Kittsy Are you a good coder or something!

@ annandale no, no coding experience at all. If I wanna do something I google it, stack overflow normally have to mix about three tutorials to get what I want. @gonorthwest , christ nothing so complicated. all the code does is literally is press button light comes on press same button again light goes off.

Getting your software to interact with your hardware is no small feat! Now just figure out how to alternate the on/off, and you're in business! Mark

Add to .h @property (nonatomic) int flashlightState; Add to .m Add #import <AVFoundation/AVFoundation.h> to your .h @synthesize flashlightState; under view did load add flashlightState = 0; Add to the button method AVCaptureDevice *device = [AVCaptureDevice defaultDeviceWithMediaType:AVMediaTypeVideo]; // If torch supported, add button to toggle flashlight on/off if ([device hasTorch] == YES) {insert your code to create button here, button should then call self perform [self flashlightStateControl] -(void) flashlightStateControl { if (flashlightState == 1) { [self torchOff]; flashlightState = 0; } else { [self torchOn]; flashlightState = 1; } } -(void)torchOn{ AVCaptureDevice *device = [AVCaptureDevice defaultDeviceWithMediaType:AVMediaTypeVideo]; [device lockForConfiguration:nil]; [device setTorchMode: AVCaptureTorchModeOn]; [device unlockForConfiguration]; } -(void)torchOff{ AVCaptureDevice *device = [AVCaptureDevice defaultDeviceWithMediaType:AVMediaTypeVideo]; [device lockForConfiguration:nil]; [device setTorchMode: AVCaptureTorchModeOff]; [device unlockForConfiguration];

oh can do that it was a pain -(void) flashlightStateControl { if (flashlightState == 1) { [self torchOff]; flashlightState = 0; } else { [self torchOn]; flashlightState = 1; } }

writing a little code for GoNorthWest. must be getting better dude cos I've used your post and guides for all kinds. Nice to give a liitle back

Thanks, @kittsy! We all have our niches to fill here...not being able to code (and not really having the time to sit down and learn) is why I'm at buzztouch in the first place! The cool thing is that I'm actually able to understand some of what you wrote thanks to @David's plugin tutorial! Mark

why do people do this too me now I'm trying to think of a way to make it blink. I reckon in english use the above code turn on turn off press button > start pattern code (void)pattern code{ [self turnOn] [self performSelector:@selector(turnOff) withObject:nil afterDelay:0.2]; [self performSelector:@selector(turnOn) withObject:nil afterDelay:0.2]; etc }

I've become addicted, I wouldn't say I understand fully what the code does. But by downloading example projects from github and such I'm learning how it all pieces together.

Love it! I think you're on the way to a cool Strobe Light plugin! You could provide a selector for the frequency, and then it would fire the light at that frequency, which could be used to check RPMs of various objects! Cool stuff!

@Andrew....dude you are sharing some amazing stuff the last few days! Thank you!

That could really become useful. This could really become useful for many people. You should make a plugin with this feature and make some money out of it. It would be great to have. I'd be happy to pay.

Amazing info Kittsy and would like to see both of your blogs live soon...
