ios - 从 UITableViewCell 将 UIImageView 扩展到全屏

Question

我在 UITableViewCell 中有一个 UIImageView 并希望将其展开以填满全屏，我已经设置了我的 UIGestureRecognizer 并正在使用扩展框架的代码:

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

但是 UIImageView 只会展开以填充 UITableViewCell 而不会填充全屏。

任何帮助将不胜感激。

Answer 1

cells clipsToBounds is set to Yes, so view outside the cell bound will not visible

以下方法将帮助您将单元格中的图像全屏显示，然后将其放回原处。

你需要在imageView中添加gestureRecognizer，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;
}
