如何放大单元格中的图像

Question

我在表格视图单元格中插入图像视图。我希望它将图像放大到全屏。因为它太小，请帮助我。非常非常感谢！这是我的代码如下：

- (UITableViewCell*)tableView:(UITableView *)tableView cellForRowAtIndexPath: (NSIndexPath *)indexPath{ 
static NSString *identifier = @"identifier"; 
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:identifier]; 

if (cell == nil) { 
    cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:identifier]; 


    // 
    cell.selectionStyle =UITableViewCellSelectionStyleNone; 
    //set the background 
    cell.backgroundColor = [UIColor clearColor]; 

}else { 

    [[cell.contentView  subviews]makeObjectsPerformSelector:@selector(removeFromSuperview)]; 

} 

NSArray *images = @[@"po", @"po", @"po", @"po",@"po", @"po", @"po", @"po", @"po", @"po",@"po", @"po", @"po", @"po", @"po", @"po",@"po", @"po", @"po", @"po", @"po", @"po", @"po",@"po", @"po", @"po", @"po", @"po", @"po",@"po", @"po", @"po", @"po", @"po", @"po",@"po", @"po", @"po"]; 

//and an text view 
UITextView *hisText = [[UITextView alloc] init]; 
hisText.frame = CGRectMake(100, 110, 600, 350); 
[hisText setFont:[UIFont fontWithName:@"HelveticaNeue" size:14]]; 
hisText.textColor = [UIColor blackColor]; 
hisText.editable = NO; 


//set the image view 
UIImageView *hisImg =[[UIImageView alloc] init]; 
hisImg.frame = CGRectMake(106, 170, 575, 140); 


switch (indexPath.row) { 
    case 0: 
     hisText.frame = CGRectMake(100, 120, 600, 500); 
     hisText.text = @"Lorem ipsum dolor sit er elit lamet, consectetaur cillium adipisicing pecu, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.

     hisImg.image = [UIImage imageNamed:@"1928-1.jpg"]; 
     [cell.contentView addSubview:hisText]; 
     [cell.contentView addSubview:hisImg]; 
     break; 
    case 1: 
     hisText.frame = CGRectMake(100, 155, 600, 405); 
     hisText.text = @"Lorem ipsum dolor sit er elit lamet, consectetaur cillium adipisicing pecu, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam.”"; 
     [cell.contentView addSubview:hisText]; 
     break; 
    default: 
     break; 
}// 


cell.imageView.image = [UIImage imageNamed:images[indexPath.row]]; 

return cell; 
} 

有人帮助我.please，任何人在这里？

您可以在点击事件中做到这一点。你可以从didSelectRowAtIndexPath得到索引。然后拍摄图像视图并添加为表视图的子视图。希望你能理解。 :)
