ios - 无法识别超出父 View 范围的 UILabel 上的点击

Question

我有一个情况:

            -------------
            |           |
-------------------------
| UILabel               |
-------------------------
            | UIView    |
            |           |
            -------------

我需要检查用户是否点击了 UILabel。 UILabel 是 UIView 的 subview 。

result.userInteractionEnabled = YES;
textLabel.userInteractionEnabled = YES;
[result addSubview: textLabel];

UITapGestureRecognizer *tapRecognizer = [[UITapGestureRecognizer alloc] initWithTarget: self action: @selector(reportTap:)];
tapRecognizer.delaysTouchesBegan = YES;
[textLabel addGestureRecognizer: tapRecognizer];

所以点击只能在 UIView 上识别，我试图覆盖 - (UIView *) hitTest: (CGPoint)point withEvent: (UIEvent *)event 但它从未被调用，试图添加tapRecognizer 到 UILabel ==> 这也不能解决问题。有什么帮助吗？

希望这对你有帮助。

- (BOOL)pointInside:(CGPoint)point withEvent:(UIEvent *)event {

BOOL isInside = [super pointInside:point withEvent:event];

// identify the label view subclass
UILabel * textLabel = (UILabel *)[result viewWithTag:1];
CGPoint inLabelSpace = [self convertPoint:point toView:textLabel];

BOOL isInsideLabel = [textLabel pointInside:inLabelSpace withEvent:nil];

if (YES == isInsideLabel) {

    return isInsideLabel;

} // if (YES == isInsideLabel)


return isInside;

}
