我正在 iPhone 中开发一个应用程序。一种视图支持纵向和横向方向。对于两个方向，我都有两个单独的视图。此视图UIToolbar顶部有一个。
问题是当我将视图从横向更改回纵向UIToolbar时，顶部消失了。toolbar当它旋转回纵向时，我希望它回到原来的位置。
这就是我在我的程序中所做的：
- (void)willAnimateRotationToInterfaceOrientation:(UIInterfaceOrientation)
interfaceOrientation duration:(NSTimeInterval)duration {
if (interfaceOrientation == UIInterfaceOrientationPortrait)
{
self.view = self.portrait;
self.view.transform = CGAffineTransformIdentity;
self.view.transform = CGAffineTransformMakeRotation(degreesToRadian(0));
self.view.bounds = CGRectMake(0.0, 0.0, 300.0, 480.0);
}
else if (interfaceOrientation == UIInterfaceOrientationLandscapeLeft)
{
self.view = self.landscape;
self.view.transform = CGAffineTransformIdentity;
self.view.transform = CGAffineTransformMakeRotation(degreesToRadian(-90));
self.view.bounds = CGRectMake(0.0, 0.0, 460.0, 320.0);
}
else if (interfaceOrientation == UIInterfaceOrientationPortraitUpsideDown)
{
self.view = self.portrait;
self.view.transform = CGAffineTransformIdentity;
self.view.transform = CGAffineTransformMakeRotation(degreesToRadian(180));
self.view.bounds = CGRectMake(0.0, 0.0, 300.0, 480.0);
}
else if (interfaceOrientation == UIInterfaceOrientationLandscapeRight)
{
self.view = self.landscape;
self.view.transform = CGAffineTransformIdentity;
self.view.transform =
CGAffineTransformMakeRotation(degreesToRadian(90));
self.view.bounds = CGRectMake(0.0, 0.0, 460.0, 320.0);
}
}
我不知道我在这里错过了什么？任何帮助将非常感激。
