UIImageView圖像在放置大圖像時發生扭曲

嘗試在UIImageView中設置大圖像時，圖像的分辨率會變形。有沒有什麼辦法讓圖像保持相同的分辨率，而將圖像放在較小的視圖中？UIImageView圖像在放置大圖像時發生扭曲

嘗試將imageview內容模式設置爲aspectfit。

imageView.contentMode = UIViewContentModeScaleAspectFit;

UIViewContentModeScaleAspectFit適合圖像，並剪切其餘部分。有沒有辦法使圖像適合imageview的大小而不失真？ –

設定尺寸後設置contentMode

[imageView setContentMode: UIViewContentModeScaleAspectFit]; 
imageView.frame = CGRectMake(x, y, width, height);

謝謝，非常有價值的信息。 –

我的圖像調整到包含圖像的UIImageView的大小固定的這個問題必須發生。

對我而言，imageView.contentMode = UIViewContentModeScaleAspectFit也沒有設置imageView的框架工作。

方案：

我使用從XIB一個UITableViewCell，它有一個的UIImageView。我以編程方式設置了UIImageView的圖像。
