如何放大單元格中的圖像

Question

我在表格視圖單元格中插入圖像視圖。我希望它將圖像放大到全屏。因爲它太小，請幫助我。非常非常感謝！這是我的代碼如下：

- (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; 
} 

有人幫助我.please，任何人在這裏？

您可以在點擊事件中做到這一點。你可以從didSelectRowAtIndexPath得到索引。然後拍攝圖像視圖並添加爲表視圖的子視圖。希望你能理解。 :)
