iphone - UIAnimation 导致 XCode 在一段时间后崩溃
<p><p>我的应用程序在闲置 5-7 分钟后在 XCode 中崩溃。我确定这与用于加载屏幕的动画有关 - 我粘贴了下面的代码。</p>
<p>我尝试启用 Zombie Objects 以查看它是否是对已释放对象的调用,并附上调试窗口崩溃时的屏幕截图。</p>
<p>顺便说一句 - 如果我按“恢复”,应用程序将继续正常运行..</p>
<p>编辑:这是第一次。我设置的全局断点在 <code>[UIView animateWithDuration:0.2...</code> 行停止,这是输出代码(这次硬崩溃了):</p>

<p><p>第二个动画的完成 block 递归调用 startAnimating。我认为这是问题的原因。您应该改用循环或创建重复动画。</p></p>
