这是我正在做的事情:
首先,将此定义放在文件顶部,就在您的#imports 下方:
#define degreesToRadian(x) (M_PI * (x) / 180.0)
然后,在 viewWillAppear: 方法中
[[UIApplication sharedApplication] setStatusBarHidden:YES animated:NO];
if (self.interfaceOrientation == UIInterfaceOrientationPortrait) {
self.view.transform = CGAffineTransformIdentity;
self.view.transform = CGAffineTransformMakeRotation(degreesToRadian(90));
self.view.bounds = CGRectMake(0.0, 0.0, 480, 320);
}
如果你想让它被动画化,那么你可以将整个东西包装在一个动画块中,如下所示:
[UIView beginAnimations:@"View Flip" context:nil];
[UIView setAnimationDuration:1.25];
[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
[[UIApplication sharedApplication] setStatusBarHidden:YES animated:NO];
if (self.interfaceOrientation == UIInterfaceOrientationPortrait) {
self.view.transform = CGAffineTransformIdentity;
self.view.transform = CGAffineTransformMakeRotation(degreesToRadian(90));
self.view.bounds = CGRectMake(0.0, 0.0, 480, 320);
}
[UIView commitAnimations];
