從滾動視圖打開圖像到新的視圖控制器

Question

我有一個UIScrollView，其中包含多個UIImageViews。

我想知道從滾動視圖中竊聽了哪個UIImageView。

謝謝

Answer 1

將手勢識別器添加到圖像視圖，然后在視圖控制器（模式）中將其打開

使用UIGestureRecognizerDelegate委托

UITapGestureRecognizer *gestureTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(doubleTap:)];
gestureTap.delegate = self;
gestureTap.numberOfTapsRequired = 2;
[image addGestureRecognizer:gestureTap];
[gestureTap release];



- (void)doubleTap:(UIPanGestureRecognizer *)gesture {
    NSLog(@"double tap on %@", gesture.view);

}

- (BOOL)gestureRecognizerShouldBegin:(UIGestureRecognizer *)gestureRecognizer {
    return YES;
}
