如何在iOS应用程序中使图像全屏显示

我是xcode和objective c的新手，我想知道如何使用轻触手势使图像在触摸屏上全屏显示。。。 有人能帮我吗

以下是我尝试过的代码：

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

UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleTap:)];
tap.numberOfTapsRequired = 1;
tap.cancelsTouchesInView = NO;
imageView.userInteractionEnabled = YES;
[imageView addGestureRecognizer:tap];
}

-(void)handleTap{
imageView.frame=CGRectMake(0,0,320,480);

}

您可以更改imageview的帧大小，然后它会自动进入全屏模式

UITapGestureRecognizer *tapGesture = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleTapGesture)];
tapGesture.numberOfTapsRequired=1;
[imageView setUserInteractionEnabled:YES];
[imageView addGestureRecognizer:tapGesture];

-(void)handleTapGesture{
    imageView.frame=CGRectMake(0,0,320,480);

}

这个

可能会成功

谢谢！我要把什么放在哪里？那么我要在.h文件中写什么呢？我刚刚收到一条错误消息：@autoreleasepool{return UIApplicationMain（argc，argv，nil，NSStringFromClass（[AppDelegate class]）；你在什么时候保存了这段代码？我把它放在viewdiload[super viewdiload]下面，在你的问题中发布你曾经尝试过的代码。在@selector中删除冒号（：）（handleTap:）并重试。检查：-不要忘记imageView.contentMode=UIViewContentModeScaleToFill；

    UITapGestureRecognizer *tapGesture = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleTap:)];
    tapGesture.numberOfTapsRequired = 1;
    tapGesture.cancelsTouchesInView = NO;
    imageView.userInteractionEnabled = YES;
    [imageView addGestureRecognizer:tapGesture];

    -(void)handleTemplateTap:(UIGestureRecognizer *)sender
    {
         imageview.frame=CGRectMake(0,0,self.view.frame.size.width,self.view.frame.size.height);
    }

    UITapGestureRecognizer *tapGesture = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleTap:)];
    tapGesture.numberOfTapsRequired = 1;
    tapGesture.cancelsTouchesInView = NO;
    imageView.userInteractionEnabled = YES;
    [imageView addGestureRecognizer:tapGesture];

    -(void)handleTemplateTap:(UIGestureRecognizer *)sender
    {
         imageview.frame=CGRectMake(0,0,self.view.frame.size.width,self.view.frame.size.height);
    }
