ios - UIImageView 旋转后不居中

Question

我手动将 UIImageView 添加到我的 UIView 并将其居中，这工作正常，但在旋转设备后，UIImageView 不再居中(它移到了左下方)。我该如何解决这个问题？

logoView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"wi-fi-sticker.png"]];
logoView.center = self.view.center;
[self.view addSubview:logoView];

问候，萨沙

Answer 1

每次使用这样的东西我都能正确地居中

-(void)willAnimateRotationToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration:{
       CGRect screen = [[UIScreen mainScreen] bounds];
       float pos_y, pos_x;
       pos_y = UIDeviceOrientationIsLandscape(toInterfaceOrientation) ? screen.size.width/2  : screen.size.height/2;
       pos_x = UIDeviceOrientationIsLandscape(toInterfaceOrientation) ? screen.size.height/2 : screen.size.width/2;

       myImageView.center = CGPointMake(pos_x, pos_y);
}
