Fix touch delay on controls in scroll views

All subclasses of UIScrollView will delay touch delivery to any UIControls inside.

This delay is about 1 second and creates a sensible stutter. There is a simple fix that additionally adds a feature to cancel touch on control if it turned into panning.

@implementation MYCollectionView

- (id)initWithCoder:(NSCoder *)aDecoder {
 if(self = [super initWithCoder:aDecoder]) {
 // Disable touch delays to avoid highlighting delay on UIControls
 self.delaysContentTouches = NO;
 }
 return self;
}

- (BOOL)touchesShouldCancelInContentView:(UIView *)view {
 // Cancel tap on UIControls if user moved finger
 return YES;
}

@end
