ios - 旋转后 UIImageView 不居中
<p><p>我手动将 UIImageView 添加到我的 UIView 并将其居中，这工作正常，但是在旋转设备后， UIImageView 不再居中(它移动到左下角)。我该如何解决这个问题？</p>
<pre><code>logoView = [ initWithImage:];
logoView.center = self.view.center;
;
</code></pre>
<p>问候，

<p><p>每次使用这样的东西我都能正确地居中</p>
<pre><code>-(void)willAnimateRotationToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration:{
CGRect screen = [ 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);
}
</code></pre></p>
