I added 2 new methods to category UIColor.
1
+ ( 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 colorWithRed: red/ 255.0 green: green/ 255.0 blue: blue/ 255.0 alpha: alpha/ 255.0 ] ;} + ( UIColor * ) colorWithHexRed: ( int ) red green: ( char ) green blue: ( char ) blue alpha: ( char ) alpha { int x = 0 ;= ( red & 0xff) << 24 ;= ( green & 0xff) << 16 ;= ( blue & 0xff) << 8 ;= ( alpha & 0xff) ;return [ UIColor colorWithHex: x] ;}
Example:
1
UIColor * redColor = [ UIColor colorWithHex: 0xff0000ff] ;
First 6 symbols like HTML color, latest 2 symbols it’s alpha.

Enable MSAA Anti-Aliasing in GLKit.
Just enable:
1
GLKView * view = ( GLKView * ) self.view;= GLKViewDrawableMultisample4X;
Without MSAA:
With MSAA:
GLKit_MSAA_Sample

Distance between vertices:
1
static inline GLfloat Vertex3DDistanceBetweenVertices( Vertex3D vertex1, Vertex3D vertex2) { = vertex2.x - vertex1.x;= vertex2.y - vertex1.y; = vertex2.z - vertex1.z;return sqrtf( ( deltaX * deltaX) + ( deltaY * deltaY) + ( deltaZ * deltaZ) ) ;}
Magnitude of a vector:
1
static inline GLfloat Vector3DMagnitude( Vector3D vector) { return sqrtf( ( vector.x * vector.x) + ( vector.y * vector.y) + ( vector.z * vector.z) ) ; }

My simple solution by writing category for UIImageView, because scroller is imageview.
How to use :)
1
#define noDisableVerticalScrollTag 836913 #define noDisableHorizontalScrollTag 836914 @implementation UIImageView ( ForScrollView) - ( void ) setAlpha: ( float ) alpha { if ( self.superview.tag == noDisableVerticalScrollTag) { if ( alpha == 0 && self.autoresizingMask == UIViewAutoresizingFlexibleLeftMargin) { if ( self.frame.size.width < 10 && self.frame.size.height > self.frame.size.width) { * sc = ( UIScrollView* ) self.superview;if ( sc.frame.size.height < sc.contentSize.height) { return ;} } } } if ( self.superview.tag == noDisableHorizontalScrollTag) { if ( alpha == 0 && self.autoresizingMask == UIViewAutoresizingFlexibleTopMargin) { if ( self.frame.size.height < 10 && self.frame.size.height < self.frame.size.width) { * sc = ( UIScrollView* ) self.superview;if ( sc.frame.size.width < sc.contentSize.width) { return ;} } } } [ super setAlpha: alpha] ;} @end
If you want both scroll it’s easy to change code.

I tried create loop by AVQueuePlayer, this method has delays between end and start play.
for looping AVQueuePlayer i use this code:
1
[ [ NSNotificationCenter defaultCenter
] addObserver
: self
selector
: @selector ( playerItemDidReachEnd
: )
name
: AVPlayerItemDidPlayToEndTimeNotification
object
: self.mPlayerItem
] ;
[ self player
] .actionAtItemEnd
= AVPlayerActionAtItemEndNone;
and playerItemDidReachEnd
1
- ( void ) playerItemDidReachEnd
: ( NSNotification * ) notification
{
AVPlayerItem
* p
= [ notification object
] ;
[ p seekToTime
: kCMTimeZero
] ;
}
Another solution without hiccups/delays based on AVMutableComposition![Read more...]

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
1
AudioSessionAddPropertyListener ( kAudioSessionProperty_AudioRouteChange, callbackHeadphone_func, self) ;
Listener callback
1
void callbackHeadphone_func
( void * inClientData, AudioSessionPropertyID inID, UInt32 inDataSize,
const void * inData
) {
if ( inID
== kAudioSessionProperty_AudioRouteChange
) {
[ mainViewController performSelector
: @selector ( isHeadsetPluggedIn
) ] ;
}
}
- ( void ) isHeadsetPluggedIn
{
UInt32 routeSize
= sizeof ( CFStringRef
) ; CFStringRef route;
AudioSessionGetProperty
( kAudioSessionProperty_AudioRoute,
& routeSize,
& route
) ;
/* Known values of route:
NSString * routeStr
= ( NSString * ) route;
DLog
( @ "%@" ,routeStr
) ;
}

I have this text:
1
word1 word2 " word3 //" word4
I wrote simple solution. I know it can be better. I know about Back Reference, but i don’t have experience with it.

for ( NSTextCheckingResult

) {
// set color for range

BOOL inside

Now we have controller for creating events. This controller included from 4.0 iOS SDK.
SimpleEKDemo
The application uses table views to display EKCalendar object and EKEvent objects retrieved from an EKEventStore object. It implements EKEventViewController for viewing and editing existing EKEvents, and uses EKEventEditViewController for creating new EKEvents.

DDProgressView is a custom progress view a la Twitter for iPhone.
DDProgressView works on both iOS and Mac OS. You must also compile the AppKitCompatibility.m file when targeting Mac OS.
Thanks, Damien DeVille
