iPhone：UIImageView 淡入 - 如何？

我有一个UIImageView我想淡入。

有没有办法在底层启用它UIViewController?

我翻译了最简单的答案，尽管它们都有效，C# .NET为了MonoTouch users:

public override void ViewDidAppear (bool animated)
{
    base.ViewDidAppear (animated);
    UIView.BeginAnimations ("fade in");
    UIView.SetAnimationDuration (1);
    imageView.Alpha = 1;
    UIView.CommitAnimations ();
}

最初将 imageview 的 alpha 设置为 0imageView.alpha = 0;

- (void)fadeInImage 
{
[UIView beginAnimations:@"fade in" context:nil];
    [UIView setAnimationDuration:1.0];
    imageView.alpha = 1.0;
    [UIView commitAnimations];

}
