iphone – iOS App在模拟器上运行但不在设备上运行？

int retVal = UIApplicationMain(argc,argv,nil,nil);

由于我的代码似乎没问题,有没有人知道什么样的东西一般会导致这种行为？

我还能在哪里寻找可能的错误？我得到的所有对SIGABRT的引用都是汇编… 0.o

This generally means that another instance of this process was already running or is hung in the debugger.(gdb)

不知道另一个进程在哪里运行…我从iPhone中删除了应用程序,清理了我的项目,然后再次运行它(一旦停止按钮显示为灰色,我认为这意味着程序中没有进程正在运行) .
