从UITableViewCell内将UIImageView扩展为全屏

Question

我有一个UIImageView内部的UITableViewCell,并希望将它扩大到充满整个屏幕,我有我的设置UIGestureRecognizer和我使用此代码扩展框架:

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

但是,UIImageView只会扩展以填充UITableViewCell并且不会填满整个屏幕.

任何帮助将非常感激.

cells clipsToBounds设置为Yes,因此单元格边界外的视图将不可见

以下方法将帮助您将单元格中的图像转换为全屏,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; 作为实例变量.

- (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;
}
