为什么我的 UIView 在加载完成后不保持透明？
我有一个以模态方式显示的视图，在显示它之前，我将其背景颜色设置为透明...
- (void)viewDidAppear:(BOOL)animated
{
[super viewDidAppear:animated];
MyViewController_iPhone *myVC = [[MyViewController_iPhone alloc] initWithNibName:@"MyView" bundle:nil];
[myVC.view setBackgroundColor:[UIColor colorWithRed:0 green:0 blue:0 alpha:0.0]]
[[self navigationController] presentModalViewController:myVC animated:YES];
[myVC release];
}
当视图在屏幕上动画时，背景是透明的，但一旦完成向上动画，视图的背景回到原来不透明的白色，为什么？
预先感谢您的帮助！
I have a view being displayed modally and, before I display it, I set it's background color to transparent...
- (void)viewDidAppear:(BOOL)animated
{
[super viewDidAppear:animated];
MyViewController_iPhone *myVC = [[MyViewController_iPhone alloc] initWithNibName:@"MyView" bundle:nil];
[myVC.view setBackgroundColor:[UIColor colorWithRed:0 green:0 blue:0 alpha:0.0]]
[[self navigationController] presentModalViewController:myVC animated:YES];
[myVC release];
}
As the view animates up onto the screen, the background is transparent, but as soon as it finishes animating upward, the view's background goes back to the original opaque white color, why?
Thanks in advance for your help!
