本文介绍了从UITableViewCell内将UIImageView扩展为全屏的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我在 UITableViewCell 中有一个 UIImageView ，并希望将其展开以填满整个屏幕，我已设置我的 UIGestureRecognizer 并使用此代码扩展框架：

  [ UIView animateWithDuration：1.0动画：^ {
 [self.ImageView setFrame：[[UIScreen mainScreen] applicationFrame]]; 
}];

然而 UIImageView 只会扩展为填充 UITableViewCell 并没有填满整个屏幕。

我们非常感谢任何帮助。

以下方法将帮助您将单元格中的图像设置为全屏，然后将其恢复到同一位置。

您需要将gestureRecognizer添加到imageView并将选择器设置为cellImageTapped

声明UIImageView * temptumb，fullview;如实例变量

   - （无效）cellImageTapped：（UIGestureRecognizer *）gestureRecognizer {
的NSLog（@％@ ，[gestureRecognizer view]）; 
 //创建新图像
 temptumb =（UIImageView *）gestureRecognizer.view; 
 // temptumb = thumbnail; 
 fullview = [[UIImageView alloc] init]; 
 [fullview setContentMode：UIViewContentModeScaleAspectFit]; 
 fullview.image = [（UIImageView *）gestureRecognizer.view image]; 
 CGRect point = [self.view convertRect：gestureRecognizer.view.bounds fromView：gestureRecognizer.view]; 
 [fullview setFrame：point]; 
 
 [self.view addSubview：fullview]; 
 
 [UIView的animateWithDuration：0.5 
动画：^ {
 [fullview SETFRAME：CGRectMake（0，
0，
 self.view.bounds.size .width，
 self.view.bounds.size.height）]; 
}]; 
 UITapGestureRecognizer * singleTap = [[UITapGestureRecognizer alloc] initWithTarget：self action：@selector（fullimagetapped :)]; 
 singleTap.numberOfTapsRequired = 1; 
 singleTap.numberOfTouchesRequired = 1; 
 [fullview addGestureRecognizer：singleTap]; 
 [fullview setUserInteractionEnabled：YES]; 
} 
  - （无效）fullimagetapped：（UIGestureRecognizer *）gestureRecognizer {
 
的CGRect点= [self.view convertRect：temptumb.bounds fromView：temptumb]; 
 
 gestureRecognizer.view.backgroundColor = [UIColor clearColor]; 
 [UIView animateWithDuration：0.5 
动画：^ {
 [（UIImageView *）gestureRecognizer.view setFrame：point]; 
}]; 
 [self performSelector：@selector（animationDone :) withObject：[gestureRecognizer view] afterDelay：0.4]; 
 
} 
 
  - （无效）animationDone：（UIView *）查看
 {
 [fullview removeFromSuperview]; 
 fullview = nil; 
}

I have a UIImageView within a UITableViewCell and want to expand it to fill the full screen, I have setup my UIGestureRecognizer and am using this code to expand the frame:

[UIView animateWithDuration:1.0 animations:^{
        [self.ImageView setFrame:[[UIScreen mainScreen] applicationFrame]];
}];

However the UIImageView will only expand to fill the UITableViewCell and does not fill the full screen.

Any help would be much appreciated.

Following method will help u to get image in cell to full Screen then get it back to same place.

You need to add gestureRecognizer to imageView and set selector as cellImageTapped

Declare UIImageView *temptumb,fullview; as instance variable.

- (void)cellImageTapped:(UIGestureRecognizer *)gestureRecognizer {
    NSLog(@"%@", [gestureRecognizer view]);
    //create new image
    temptumb=(UIImageView *)gestureRecognizer.view;
    //temptumb=thumbnail;
    fullview=[[UIImageView alloc]init];
      [fullview setContentMode:UIViewContentModeScaleAspectFit];
    fullview.image = [(UIImageView *)gestureRecognizer.view image];
        CGRect point=[self.view convertRect:gestureRecognizer.view.bounds fromView:gestureRecognizer.view];
    [fullview setFrame:point];

    [self.view addSubview:fullview];

    [UIView animateWithDuration:0.5
                     animations:^{
                         [fullview setFrame:CGRectMake(0,
                                                       0,
                                                       self.view.bounds.size.width,
                                                       self.view.bounds.size.height)];
                     }];
    UITapGestureRecognizer *singleTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(fullimagetapped:)];
    singleTap.numberOfTapsRequired = 1;
    singleTap.numberOfTouchesRequired = 1;
    [fullview addGestureRecognizer:singleTap];
    [fullview setUserInteractionEnabled:YES];
}
- (void)fullimagetapped:(UIGestureRecognizer *)gestureRecognizer {

    CGRect point=[self.view convertRect:temptumb.bounds fromView:temptumb];

    gestureRecognizer.view.backgroundColor=[UIColor clearColor];
    [UIView animateWithDuration:0.5
                     animations:^{
                         [(UIImageView *)gestureRecognizer.view setFrame:point];
                     }];
    [self performSelector:@selector(animationDone:) withObject:[gestureRecognizer view] afterDelay:0.4];

}

-(void)animationDone:(UIView  *)view
{
    [fullview removeFromSuperview];
    fullview=nil;
}
