iphone – UIImageView作为按钮

概述我试图使UIImageView接受动作，并在每次点击UIImageVie时触发它，但是我很难让它上班，请帮助我 但这里是我在做什么： [View setUserInteractionEnabled:YES];[View addTarget:self action:@selector(myAction:) forControlEvents:UIControlEventTouchUpInside] 我试图使UIImageVIEw接受动作，并在每次点击UIImageVIE时触发它，但是我很难让它上班，请帮助我

但这里是我在做什么：

[VIEw setUserInteractionEnabled:YES];[VIEw addTarget:self action:@selector(myAction:) forControlEvents:UIControlEventtouchUpInsIDe];- (voID) myAction:(ID)sender{    NSLog(@"It works!");}

解决方法 Objective-C的

在你的vIEwDIDLoad：方法写这个：

-(voID)vIEwDIDLoad {    UIImageVIEw *imagevIEw = [[UIImageVIEw alloc]initWithFrame:CGRectMake(100.0,100.0,100.0)];    [imagevIEw setimage:[UIImage imagenamed:@"image.png"]];    [imagevIEw setUserInteractionEnabled:YES];    UITapGestureRecognizer *singleTap =  [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(singleTapPing:)];    [singleTap setNumberOfTapsrequired:1];    [imagevIEw addGestureRecognizer:singleTap];    [self.vIEw addSubvIEw:imagevIEw];}

然后调用你的手势方式如下：

-(voID)singleTapPing:(UIGestureRecognizer *)recognizer {    NSLog(@"image clicked");}

迅速

overrIDe func vIEwDIDLoad() {    super.vIEwDIDLoad()    let imageVIEw: UIImageVIEw = UIImageVIEw(frame: CGRectMake(100.0,100.0))    imageVIEw.image = UIImage(named: "image.png")    imageVIEw.userInteractionEnabled = true    let singleTap: UITapGestureRecognizer = UITapGestureRecognizer(target: self,action: #selector(BaseVC.singleTapPing(_:)))    singleTap.numberOfTapsrequired = 1;    imageVIEw.addGestureRecognizer(singleTap)    self.vIEw.addSubvIEw(imageVIEw)}func singleTapPing(recognizer: UIGestureRecognizer) {    print("image clicked")}
