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 have this text: 1word1 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. 123456789101112131415161718192021222324252627282930313233NSRegularExpression *expression = [NSRegularExpression regularExpressionWithPattern:@"((@\"|\").*?(\"))"                                     [...]

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.

Example: 1234567891011121314151617181920212223242526272829303132333435363738394041- (void)viewDidLoad {     [super viewDidLoad];         // Do any additional setup after loading the view, typically from a nib.         if (self.cPicker == nil) {         [self.view setBackgroundColor:[UIColor grayColor]];         self.cPicker = [[VBColorPicker alloc] initWithFrame:CGRectMake(0, 0, 202, 202)];     [...]
