使矩形等於圖像視圖

Question

我有一個imageView。我需要將imageView的大小限制爲白色背景imageOnly。圖像在右邊界，左邊界和上邊界之間緊密限定。我很困惑如何在底部做，使圖像必須只適合在白色背景。我怎麼做 ？ http://i.stack.imgur.com/ztvQe.png

我使用

_imageView = [[UIImageView alloc] initWithFrame:CGRectMake(25, 240,175,205)]; 

幀的寬度和高度的代碼爲205 * 205

Answer 1

只需創建一個視圖，並在其中添加此圖像，例如用波紋管代碼..

UIView *ImageBackview = [[UIView alloc]initWithFrame:CGRectMake(25, 240,225,225)]; 
_imageView = [[UIImageView alloc] initWithFrame:CGRectMake(10, 10,205,205)]; 
[ImageBackview addSubview:_imageView]; 
[self.view addSubview:ImageBackview]; 

Answer 2

您可以添加您的imageView作爲與白色背景的視圖的子視圖。

UIView *whiteBackgroundView = [[UIView alloc] initWithFrame:CGRectMake(25,240,205,205)]; 
CGSize whiteSize = whiteBackgroundView.frame.size; 
_imageView = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0,size.width,size.height)]; 
[whiteBackgroundView addSubview:_imageView]; 

在這個例子中，imageView將完全適合白色背景視圖的大小。

試試這個

UIView *productView = [[UIView alloc]initWithFrame:CGRectMake(25, 240,225,225)]; 
    _imageView = [[UIImageView alloc] initWithFrame:CGRectMake(10, 10,205,205)]; 
    _imageView.clipsToBounds =YES; 
    [productView addSubview:_imageView]; 
    [self.view addSubview:ImageBackview];
