回答by NSZombie
You can create seperately a UIImage, and create your UIImageView from your UIImage.
您可以单独创建一个 UIImage，并从您的 UIImage 创建您的 UIImageView。
UIImage *myImage = [UIImage imageNamed:@"great_pic.png"];
UIImageView *myImageView = [[UIImageView alloc] initWithImage:myImage];
Then, set the size of your UIImageView
然后，设置 UIImageView 的大小
[myImageView setFrame:CGRectMake(0, 0, 100, 200)];
Do whatever you want with your image, but don't forget to release it.
对图像做任何你想做的事情，但不要忘记释放它。
[anotherView addSubview:myImageView];
[myImageView release];

The answers so far are more complex than they need to be: initWithImage: “adjusts the frame of the receiver to match the size of the specified image.” So all you need is
到目前为止，答案比他们需要的要复杂：initWithImage：“调整接收器的帧以匹配指定图像的大小。” 所以你只需要
UIImageView* v = [[UIImageView alloc] initWithImage: someImage];
