objective-c - 将 UITapGestureRecognizer 添加到 UIVIew XIB

Question

@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");
}

我已将 Tap Gesture Recognizer 添加到我的 kOverlayNib.xib 但由于某种原因我无法得到任何响应..它根本不工作..

Answer 1

你错过了一些东西..

1. @interface MyCustomView() <UIGestureRecognizerDelegate> @end或任何你想写的地方。

2. singleFingerTap.delegate = self;

3. - (BOOL)gestureRecognizer:(UIGestureRecognizer )gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer)otherGestureRecognizer { return YES; }

现在你可以运行你的代码了。有用。
