Notes of a Developer

UIBezierPath is a convenient object for creating rounded-rectangular shapes. Starting from 3.2, this class becomes public, but the interface is dramatically changed to match that of NSBezierPath. 12345678910-(void)drawRect:(CGRect)rect {   UIBezierPath* roundedRect = [UIBezierPath roundedRectBezierPath:CGRectInset(rect, 5, 5)                                     [...]

I create simple project for iOS, “One minute”. This project create video from photos on iOS device. Results of app:

I added 2 new methods to category UIColor. 123456789101112131415161718+ (UIColor* ) colorWithHex:(int)color {     float red = (color & 0xff000000) >> 24;     float green = (color & 0x00ff0000) >> 16;     float blue = (color & 0x0000ff00) >> 8;     float alpha = (color & 0x000000ff);     return [UIColor [...]

Enable MSAA Anti-Aliasing in GLKit. Just enable: 12GLKView *view = (GLKView *)self.view; view.drawableMultisample = GLKViewDrawableMultisample4X; Without MSAA:   With MSAA: GLKit_MSAA_Sample

My simple solution by writing category for UIImageView, because scroller is imageview. How to use :) Just setup tag for your scrollview and you will get one with scroll indicators, which are shown all the time. 1234567891011121314151617181920212223242526272829303132#define noDisableVerticalScrollTag 836913 #define noDisableHorizontalScrollTag 836914 @implementation UIImageView (ForScrollView) – (void) setAlpha:(float)alpha {         if (self.superview.tag [...]

I tried create loop by AVQueuePlayer, this method has delays between end and start play. for looping AVQueuePlayer i use this code: 123456[[NSNotificationCenter defaultCenter] addObserver:self                                              selector:@selector(playerItemDidReachEnd:)               [...]

if you will use or used AVPlayer or you want just know about changes, you can check AudioRouteChange. Simple solution: Add framework AudioToolbox and add import to file 1#import <AudioToolbox/AudioToolbox.h> Insert into init method or any other 1AudioSessionAddPropertyListener (kAudioSessionProperty_AudioRouteChange, callbackHeadphone_func, self); Listener callback 12345678910111213141516171819202122232425void callbackHeadphone_func ( void *inClientData, AudioSessionPropertyID inID, UInt32 inDataSize, const void *inData [...]
