问题描述
每次我在iPad模拟器上运行我的应用程序时，它都能完美运行。但是，当我在iPhone模拟器上运行它时，当我单击主页按钮时，我在main.m文件中的Xcode中出现错误，说线程1：程序接收信号：SIGABRT。它是突出在我的main.m的代码行：返回UIApplicationMain（的argc，argv的，零，NSStringFromClass（[AppDelegate类]））;
Everytime I run my app on the iPad simulator, it works flawlessly. But, when I run it on the iPhone simulator, when I click the home button, I get an error in Xcode in my main.m file, saying "Thread 1: Program received signal: SIGABRT". It is highlighting this line in my main.m's code: return UIApplicationMain(argc, argv, nil, NSStringFromClass([AppDelegate class]));
当我按下iPad模拟器上的主页按钮时，不会发生此问题。我在这里做了很多关于这个错误的研究，但似乎没有什么用处。有谁知道如何解决这个问题？
This issue doesn't occur when I press the home button on the iPad simulator at all though. I've done a lot of research on here about this error, but nothing useful seemed to turn up. Does anyone know how to go about fixing this?
编辑：这是调试器控制台的更多信息
here is some more info from the debugger console
无法与引导服务器注册None.TestApplication错误：未知错误代码
这通常意味着这个过程的另一个实例已经运行或在debugger.sharedlibrary应用负载规则是挂满
当前语言：auto;目前objective-c
（gdb）

推荐答案
该行 UIApplicationMain（argc，argv，nil，NSStringFromClass（[AppDelegate class]））; 只是意味着在程序运行期间抛出了异常。这可能来自内存问题，简单的运行时错误。查看目标调试器控制台;它将告诉您错误发生的位置。
The line UIApplicationMain(argc, argv, nil, NSStringFromClass([AppDelegate class])); just means that an exception was thrown during the running of your program. This could range from a memory problem, to a simple runtime error. Look in the target debugger console; it will tell you where the error occurred.
由于编辑而编辑问题：我之前已经通过将iOS模拟器恢复为出厂默认设置解决了这个问题（打开iOS模拟器M左上角的enu - >重置内容和设置）。然后退出iOS模拟器和Xcode，然后重新启动计算机。这将摆脱该过程的另一个实例。
Edited due to edited question: I have solved this question before by restoring the iOS simulator to factory defaults (Open "iOS Simulator" Menu in the upper left -> Reset Content and Settings). Then quit the iOS simulator and Xcode, and then restart your computer. This will get rid of the other instance of the process.
