我通過捕獲任何異常並手動記錄它們來執行自己的錯誤處理。我使用NSSetUncaughtExceptionHandler(&myExceptionHandler);
並使用[NSException callStackSymbols]
記錄堆棧跟蹤。直到最近我的日誌包含符號化的堆棧跟蹤。現在他們沒有,也沒有任何與日誌記錄相關的代碼更改。這發生在iOS的所有設備和版本上。我能夠手動表示我的日誌,但它非常麻煩。任何有識之士將不勝感激。Stacktrace不再具有象徵意義
以前我的日誌看起來像:
0 libobjc.A.dylib 0x352925b0 objc_msgSend + 16
1 MYAPP 0x0006573a -[MyViewController(Images) didReceiveImage:context:etag:expires:] + 42
2 MYAPP 0x0004fb26 -[MyImageTask didReceiveImage:] + 98
3 Foundation 0x361ac8e8 __NSThreadPerformPerform
4 CoreFoundation 0x3b37d680 __CFRUNLOOP_IS_CALLING_OUT_TO_A_SOURCE0_PERFORM_FUNCTION__
5 CoreFoundation 0x3b37cee4 __CFRunLoopDoSources0
6 CoreFoundation 0x3b37bcb2 __CFRunLoopRun
7 CoreFoundation 0x3b2eeeb8 CFRunLoopRunSpecific
8 CoreFoundation 0x3b2eed44 CFRunLoopRunInMode
9 GraphicsServices 0x396bc2e6 GSEventRunModal
10 UIKit 0x3452e2f4 UIApplicationMain
11 MYAPP 0x0004934a main + 70
12 MYAPP 0x000492fc start + 36
我的最後一個版本後,他們看起來像:
0 libobjc.A.dylib 0x352925b0 objc_msgSend + 16
1 MYAPP 0x0006573a - MYAPP + 42
2 MYAPP 0x0004fb26 - MYAPP + 98
3 Foundation 0x361ac8e8 __NSThreadPerformPerform
4 CoreFoundation 0x3b37d680 __CFRUNLOOP_IS_CALLING_OUT_TO_A_SOURCE0_PERFORM_FUNCTION__
5 CoreFoundation 0x3b37cee4 __CFRunLoopDoSources0
6 CoreFoundation 0x3b37bcb2 __CFRunLoopRun
7 CoreFoundation 0x3b2eeeb8 CFRunLoopRunSpecific
8 CoreFoundation 0x3b2eed44 CFRunLoopRunInMode
9 GraphicsServices 0x396bc2e6 GSEventRunModal
10 UIKit 0x3452e2f4 UIApplicationMain
11 MYAPP 0x0004934a main + 70
12 MYAPP 0x000492fc start + 36
