I am trying to run app on the iphone 6 and I get this error. I get the error after making the facebook login. Normally, it is working successfully on the simulator. I couldn't find why it gives the error.

错误:

 *** Terminating app due to uncaught exception 'NSRangeException', reason: '*** -[__NSArray0 objectAtIndex:]: index 0 beyond bounds for empty NSArray'
    *** First throw call stack:
    (0x181dcae38 0x18142ff80 0x181d41a6c 0x100418620 0x100417aa0 0x10042dbac 0x10006a3a0 0x10006aa0c 0x186f14b40 0x186f14744 0x1872ba9fc 0x1872774f4 0x187273f04 0x1871c6fd8 0x1871d4990 0x186f064a4 0x181d807b0 0x181d7e554 0x181d7e984 0x181ca8d10 0x183590088 0x186f7df70 0x10008810c 0x1818468b8)

推荐答案

由于您未发布任何堆栈跟踪，因此我假设您想学习如何查找此类错误.首先，在Xcode中，为Objective-C异常设置一个断点，以便您确切地了解崩溃发生的位置.

Since you posted no stack trace, I assume you want to learn how to find bugs like this. First, in Xcode, set a breakpoint on Objective-C exceptions, so you find where exactly the crash happens.

该错误清楚地表明您正在尝试为空的NSArray访问数组[0].一旦找到崩溃的位置，就应该很容易找到.

The error says clearly that you are trying to access array [0] for an NSArray that is empty. Once you find the location of the crash that should be easy to find.
