如何在iOS應用程序中使圖像變成全屏應用程序

Question

我是xcode和objective c的新手，我想知道如何使用輕擊手勢使圖像全屏觸摸... 任何人都可以幫助我？

這裏是我試過的代碼：

- (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); 

} 

Answer 1

你可以改變ImageView的的幀的大小it'l自動進入全屏模式。

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); 

} 

Answer 2

這

// Detecting touches on your UIImageView 
UITapGestureRecognizer *myImageViewTapped = [[UITapGestureRecognizer alloc] initWithTarget:self 
                       action:@selector(changeFrameOfMyImage)]; 

myImageViewTapped.cancelsTouchesInView = NO; 
[self.view addGestureRecognizer:myImageViewTapped]; 

//... 
//... 

-(void)changeFrameOfMyImage { 
    myImageView.frame = self.view.frame; 
} 

可能會做的伎倆！

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); 
    }
