ios - 使用动画推送 ViewController 时隐藏黑屏

Question

我是 iOS 开发新手。我正在使用以下代码:

AskViewController *askController=[[AskViewController alloc]initWithNibName:@"AskViewController" bundle:nil];
askController.view.transform = CGAffineTransformMakeScale(0.01, 0.01); 
[UIView beginAnimations:@"animationExpand" context:NULL];
[UIView setAnimationDuration:0.5f];
[UIView setAnimationCurve:UIViewAnimationOptionOverrideInheritedDuration];
askController.view.transform=CGAffineTransformMakeScale(1, 1);
[UIView setAnimationDelegate:self];
[UIView commitAnimations];
[self.navigationController pushViewController:askController animated:NO];

当我将 askViewcontroller 推到导航栏时，它会向我显示带黑屏动画的 AskViewcontroller。我想将该黑屏更改为白屏或任何其他彩色屏幕。

感谢任何帮助。

在您的应用委托(delegate)的 didFinishLaunchingWithOptions 方法中，添加此行:

self.window.backgroundColor = [UIColor greenColor];
