[iOS]UIScrollView 取得Touch 點技巧

使用UIScrollView時 會發現touches 抓不到點,這時候就要靠UITapGestureRecognizer來處理了

-(void)viewDidLoad{

     [super viewDidLoad];

     UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleTap:)];

     [myScrollView addGestureRecognizer: tap];
     [tap release];

}

- (void) handleTap:(id)sender {

    //執行你想要做的事情

}
