UIImageView到UIImage

Question

我有UIImageView包含靜態圖像，我想獲取此圖像並將其設置在UIImage變量下。

我該怎麼做？

Answer 1

UIImageView *imageView = ... // Set from somewhere 

UIImage *image = imageView.image; // Get the UIImage. 
UIImage *otherImage = [UIImage imageNamed:@"Icon.png"]; // Load another image. 
imageView.image = otherImage; // Change in the image in your UIImageView.
