iOS – 我的应用程序崩溃与内存错误，如果只在设备上运行
我的应用程序在模拟器上运行完美。 但是当我在设备上运行它来testing，应用程序崩溃。
显示的错误：
“对象0x17415d0c0的malloc：*错误：从空闲列表中出列的无效指针*在malloc_error_break中设置断点以进行debugging”;
而另一个错误有时会发生：
“线程6 com.apple.NSURLConnectionLoader：编程接收信号：EXC_BAD_ACCESS”
这两个错误是随机的，它发生在应用程序运行两三分钟后。
我search了Google并find了一些解决scheme。 它说，在malloc_error_break中设置一个断点来debugging，但这只能在模拟器上工作。 即使我设置malloc_error_break，应用程序仍然暗恋，它不显示任何东西，我只能看到该错误信息。
这是一个大项目，我真的不知道哪部分代码会导致问题，以及我需要发布哪部分代码。 但是我对课堂上的一个人，我的'SynchroningView'有疑问。 这个视图将显示，如果只有我的应用程序与服务器进行同步。 这意味着这个视图几乎包含在我的项目中的所有ViewController中。
这是我的'SynchroningView'类：

我终于解决了
在我的encryption和解密function，我有这样的：
Byte *buffer = (Byte*)malloc(asciiDataLength);
我用缓冲区处理后，我将其转换为NSData：
NSData *plainData = [NSData dataWithBytesNoCopy:buffer length:asciiDataLength freeWhenDone:YES];
此代码导致我的应用程序不断崩溃，我改变了
NSData *plainData = [NSData dataWithBytes:buffer length:asciiDataLength]; free(buffer);
然后我的应用程序再也不会暗恋了。
所以 ， 我必须自己释放字节，ARC不会为我释放它。
模拟器的内存= PC的RAM即4或6 GB等
和设备最多只有1 gb。 在Xcode运行应用程序时，您需要点击Debug Navigator ，然后点击Memory，它会显示您的应用程序的内存消耗。
要看你的代码中的内存泄漏 – 你必须去记忆工具，如仪器。
