Xcode full stack trace

Use the btcommand in (lldb).

Once paused or after a crash, just type btinto the debug console.
It will print the full stack trace.
一旦暂停或崩溃后，只需bt在调试控制台中输入即可。
它将打印完整的堆栈跟踪。

You can print the stack trace in the NSLog by
您可以通过以下方式在 NSLog 中打印堆栈跟踪
NSLog(@"Stack trace : %@",[NSThread callStackSymbols]);
Upon a crash, next to the word (lldb), you can type:
崩溃时，在单词旁边(lldb)，您可以键入：
po [NSThread callStackSymbols]
Edit:
