我从设备上拍摄照片（uiimagepicker相机模式）并调整图像大小并将其设置为我的图像视图。但是在点击uiimagepicker相机中的“使用”按钮后，我的应用程序因某些设备而崩溃。当许多应用程序在后台运行时（低内存问题），应用程序崩溃了。一旦我重新启动一个设备它就会工作。我的编码没有泄漏。那么如何在不重新启动的情况下解决这个问题呢？
这是我的崩溃日志

答案 0 :(得分：1)
在中检索从相机拍摄的图像后，尝试关闭选择器并将其释放。
此外，如果相机不可用，则通过创建图像拾取器来泄漏内存，并在发生错误时不释放它。
创建自动释放的UIImagePickerController，而不是release方法imagePickerController:didFinishPickingMediaWithInfo:，只是在最后解除它。
另一个问题是，除了保存原始图像的UIImage之外，您还要创建缩小的缩略图和缩略图。在这种情况下，内存压力可能会很高，所以你应该尽快摆脱内存中的图像，尤其是当你试图在图片被选中后立即上传图像时，无论你使用的是什么）正在创建另一块内存，代表要上传的图像。
尝试将选择图像，创建缩小版和缩略图的过程分开，并通过将这些代码部分移动到NSOperationQueue的单独步骤来上传它。
不要在主线程中执行所有操作，因为如果它阻止用户界面太久，您的应用程序将被运行时杀死。
