UIImageView到UIImage

Question

我有UIImageView包含静态图像，我想获取此图像并将其设置在UIImage变量下。

我该怎么做？

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.
