Вот детектор, который нормально работал на IOS 4 и 5. Есть предостережение.Если вы используете распознаватели жестов, вы должны установить глобальное значение AppTouched в false, когда они получат состояние UIGestureRecognizerStateEnded.
#import <objc/runtime.h>
Boolean AppTouched = false; // provide a global for touch detection
static IMP iosBeginTouch = nil; // avoid lookup every time through
static IMP iosEndedTouch = nil;
static IMP iosCanedTouch = nil;
// implement detectors for UIView
@implementation UIView (touchesBeganDetector)
- (void)touchesBeganDetector:(NSSet *)touches withEvent:(UIEvent *)event
{
AppTouched = true;
if ( iosBeginTouch == nil )
iosBeginTouch = [self methodForSelector:
@selector(touchesBeganDetector:withEvent:)];
iosBeginTouch( self, @selector(touchesBegan:withEvent:), touches, event );
}
@end
@implementation UIView (touchesEndedDetector)
- (void)touchesEndedDetector:(NSSet *)touches withEvent:(UIEvent *)event
{
AppTouched = false;
if ( iosEndedTouch == nil )
iosEndedTouch = [self methodForSelector:
@selector(touchesEndedDetector:withEvent:)];
iosEndedTouch( self, @selector(touchesEnded:withEvent:), touches, event );
}
@end
@implementation UIView (touchesCancledDetector)
- (void)touchesCancledDetector:(NSSet *)touches withEvent:(UIEvent *)event
{
AppTouched = false;
if ( iosCanedTouch == nil )
iosCanedTouch = [self methodForSelector:
@selector(touchesCancledDetector:withEvent:)];
iosCanedTouch( self, @selector(touchesCancelled:withEvent:), touches, event );
}
