ios - 当 iPhone 方向改变时改变 UIViews 的位置
<p><p>当 iPhone 的方向改变时,我正在尝试改变 <code>UIViews</code> 的位置。类似于 <a href="https://stackoverflow.com/questions/6104963/placing-and-moving-views-on-rotation-uiview" rel="noreferrer noopener nofollow">this question</a> ;但不是 3 个 <code>views</code>,而是 2 个 <code>views</code>。当 iPhone 处于纵向模式时,我希望 <code>views</code> 一个在另一个之上。在横向模式下,它们应该并排。</p>
<p>于是我尝试了以下方法:</p>
<pre><code>willAnimateRotationToInterfaceOrientation:duration:
</code></pre>
<p>但该方法已被弃用。如何检查 iPhone 的方向何时发生变化?</p>
<p><strong>更新</strong></p>
<p>我尝试了以下方法:感谢@Sean 的指导!!</p>
<pre><code>- (void)viewDidLayoutSubviews
{
;
self.tableView.frame = CGRectMake(0, 0, 100, 200); // This Works
}
- (void)viewWillTransitionToSize:(CGSize)size withTransitionCoordinator:(id<UIViewControllerTransitionCoordinator>)coordinator
{
;
CGFloat viewWidth = self.view.frame.size.width;
CGFloat viewHeight = self.view.frame.size.height;
if (size.width >= size.height)
{
self.containerView.frame = CGRectMake(0, 0, viewWidth, 272);
self.tableView.frame = CGRectMake(self.containerView.frame.size.height, 0, viewWidth, viewHeight - self.containerView.frame.size.height);
NSLog(@"Portrait Mode");// Get the NSLog, but frames don't change
}
else
{
self.containerView.frame = CGRectMake(0, 0, viewWidth / 2, viewHeight);
self.tableView.frame = CGRectMake(viewWidth / 2, 0, viewHeight / 2, viewHeight);
NSLog(@"Landscape Mode");// Get the NSLog, but frames don't change
}
}
</code></pre>
<p>所以当我更改 <code>viewDidLayoutSubviews</code> 中的框架时,它可以工作。但是当我尝试在 <code>viewWillTransition...</code> 中更改它们时,它并没有改变,但我得到了 <code>NSLogs</code>。</p></p>
<br><hr><h1><strong>Best Answer-推荐答案</ strong></h1><br>
<p><p>Apple 建议使用以下方法:</p>
<pre><code>- (void)viewWillTransitionToSize:(CGSize)size
withTransitionCoordinator:(id<UIViewControllerTransitionCoordinator>)coordinator
</code></pre>
<p>例子:</p>
<pre><code>- (void)viewWillTransitionToSize:(CGSize)size
withTransitionCoordinator:(id<UIViewControllerTransitionCoordinator>)coordinator
{
;
if (size.width >= size.height) {
// Landscape frames
self.subviewA.frame = CGRectMake(x, y, width, height);
self.subviewB.frame = CGRectMake(x, y, width, height);
} else {
// Portrait frames
self.subviewA.frame = CGRectMake(x, y, width, height);
self.subviewB.frame = CGRectMake(x, y, width, height);
}
}
</code></pre>
<p>确保在实现此解决方案时调用如上所示的父类(super class)方法。</p></p>
