我有很少的圖像，我想在全屏幕上在iPad上展示 - 具有相同的圖像。和圖像大小不一樣。有沒有辦法拉伸圖片（UIImageView的）編程

內UIImageView你只需要設置相應的contentMode拉伸的圖像。

您可以設置的UIImageView是在屏幕的大小和設置內容模式類似如下

3個選項

// assume iv is an UIImageView the size of screen 
// First option stretches your image to the size of the screen 
[iv setContentMode:UIViewContentModeScaleToFill]; 
// Second option scales your image without changing aspect ratio to the largest possible size such that the whole image fits 
[iv setContentMode:UIViewContentModeScaleAspectFit]; 
// Third option scales your image without changing aspect ratio to the smallest possible size such that the screen is covered (potentially clipping some of your image) 
[iv setContentMode:UIViewContentModeScaleAspectFill];
