【问题描述】：

@interface MyCustomView() @end

@implementation MyCustomView

- (instancetype)init {
    self = [[[MyClass bundle] loadNibNamed:kOverlayNib owner:self options:nil] firstObject];
    self.layer.cornerRadius = 10;
    self.translatesAutoresizingMaskIntoConstraints = NO;
    self.userInteractionEnabled = YES;
    UITapGestureRecognizer *singleFingerTap =
    [[UITapGestureRecognizer alloc] initWithTarget:self
                                            action:@selector(handleSingleTap:)];
    [singleFingerTap setNumberOfTapsRequired:1];
    [singleFingerTap setNumberOfTouchesRequired:1];
    [self addGestureRecognizer:singleFingerTap];

    return self; }

//The event handling method
- (void)handleSingleTap:(UITapGestureRecognizer *)recognizer {
    NSLog(@"Tappedddddddddd");
}

我已在我的 kOverlayNib.xib 中添加了点按手势识别器，但由于某种原因我无法得到任何响应..它根本不起作用..

【问题讨论】：

UIGestureRecognizerDelegate 定义并写入singleFingerTap.delegate = self;
哦，好点，错过了那部分，谢谢！

【解决方案1】：

你错过了一些东西..

@interface MyCustomView() <UIGestureRecognizerDelegate> @end 或任何你想写的地方。
singleFingerTap.delegate = self;
- (BOOL)gestureRecognizer:(UIGestureRecognizer )gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer)otherGestureRecognizer { return YES; }

现在您可以运行您的代码了。它有效。

【讨论】：

还需要添加这个 - (BOOL)gestureRecognizer:(UIGestureRecognizer )gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer)otherGestureRecognizer { return YES; }
