Question

我遇到的问题是如何使图像视图的行为与按钮相同。

实施例。在我的.h文件

-(IBAction)ClickTheImage:(id)sender;

然后在.m文件中。

-(void)ClickTheImage:(id)sender
{
//something to do with image click.
}

但是当我尝试在我的xib文件上连接IBAction时，当我尝试连接到我的UIImageView时，就会发生这种情况。关于如何做到这一点的任何想法？。

Answer 1

确保在图片视图中将userInteractionEnabled设置为YES。然后创建并添加手势识别器，如下所示：

UITapGestureRecognizer* tapRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(ClickTheImage:)];
[self.imageView addGestureRecognizer:tapRecognizer];
self.tapRecognizer.delegate = self;

让您的课程符合UIGestureRecognizerDelegate。

Answer 2

你可以反过来创造它。创建 UIButton 并将ImageView定义为UIButton的背景图像。然后IBAction和UIButton之间的连接将起作用..

[button setBackgroundImage:buttonImage forState:UIControlStateNormal];

或者你为什么要反过来使用呢？

Answer 3

只需使用UITapGestureRecognizer

即可

在.h文件中添加GestureRecognizerDelegate。假设您的ImageView是* img;

UITapGestureRecognizer *TapRecognizer=[[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(ImageHasTouched:)];
[TapRecognizer setDelegate:self]; 
[img setUserInteractionEnable:YES];
[img addGestureRecognizer:TapRecognizer];


-(void)ImageHasTouched:(TapGestureRecognizer *)Recognizer
{
   UIImageView *TouchedImage=(UIImageView *)[[Recognizer self] view];
   //Now when ever your image will be touched this method will get fired.
   // do what ever you want
}

图像视图可在iPhone中单击，如按钮
