uiscrollview uicollectionview touch事件传递问题

uiscrollview uicollectionview 无法响应touch事件，解决方案，新建一个uiscrollview 的category

@implementation UIScrollView (UITouch)

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event

{

//if(!self.dragging)

{

[[self nextResponder] touchesBegan:touches withEvent:event];

}

[super touchesBegan:touches withEvent:event];

}

-(void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event

{

//if(!self.dragging)

{

[[self nextResponder] touchesMoved:touches withEvent:event];

}

[super touchesMoved:touches withEvent:event];

}



- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event

{

//if(!self.dragging)

{

[[self nextResponder] touchesEnded:touches withEvent:event];

}

[super touchesEnded:touches withEvent:event];

}

@end

uicollectionview 是继承uiscrollview，所以 也可以用此category，来截获touch事件
