iOS编程如何在用户点击ImageView时全屏显示图像

Question

我想在用户点击时全屏显示图像。 谁能帮帮我吗？ 我的 ImageView 在 TableViewCell 中。 这是我尝试过的:

---

-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
    ImageListTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"Cell"];
    cell.propertyImageView.frame = [UIScreen mainScreen].bounds;
    cell.propertyImageView.image = [imageList objectAtIndex:indexPath.row];
}

这样很简单:

-(void)removeImage {

    UIImageView *imgView = (UIImageView*)[self.view viewWithTag:100];
    [imgView removeFromSuperview];
}

-(void)addImageViewWithImage:(UIImage*)image {

    UIImageView *imgView = [[UIImageView alloc] initWithFrame:self.view.frame];
    imgView.contentMode = UIViewContentModeScaleAspectFit;
    imgView.backgroundColor = [UIColor blackColor];
    imgView.image = image;
    imgView.tag = 100;
    UITapGestureRecognizer *dismissTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(removeImage)];
    dismissTap.numberOfTapsRequired = 1;
    [imgView addGestureRecognizer:dismissTap];
    [self.view addSubview:imgView];
}

像这样从你的表委托(delegate)中调用:

    -(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{

   [self addImageViewWithImage:[imageList objectAtIndex:indexPath.row]];
    }
