iphone - 如何检测 subview 中的触摸事件或当我们触摸 subview 时如何使父 View 被触摸？

Question

我有 2 个 UIView。

第一个是父 View

第二个是 subview ，

我们如何检测 subview 何时被触摸？

或者我想在用户触摸 subview 时使父 View 被触摸，任何代码可以帮助我做到这一点吗？可以这样做吗？

因为我有一个 Something Function，当其中一个函数被触摸时它就会调用。

这对我有用:

(链接xib或storyboard中的 subview )

ViewController.h

@interface ViewController : UIViewController

@property (nonatomic, strong) IBOutlet UIView *subview;
@property (nonatomic, strong) UITapGestureRecognizer *tapRecognizer;

@end

ViewController.m

@implementation ViewController

@synthesize subview;
@synthesize tapRecognizer;

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.

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

    [subview addGestureRecognizer:tapRecognizer];
}

- (IBAction)handleTap:(UITapGestureRecognizer *)recognizer {
    if (recognizer.state == UIGestureRecognizerStateEnded){
        //code here
        NSLog(@"subview touched");
    }
}

@end
