這個問題遠沒有過時，因爲它要求的XCode 3，請不要考慮它的XCode有用4+。 =）斷點得到停用在Xcode中：EXC_BAD_ACCESS時NSZombieEnabled = = YES
我的應用程序崩潰的（貌似）隨機事件。所以，我想添加NSZombieEnabled來調試我的iPhone應用程序。我克隆了我的目標，並將其Info.plist設置爲與原始目標相同，並將NSZombieEnabled設置爲YES。
一旦我運行應用程序時，它的堆棧跟蹤崩潰......
#0 0x3025db0c in ___forwarding___()
#1 0x30239db2 in __forwarding_prep_0___()
#2 0x304f5105 in NSPopAutoreleasePool()
#3 0x308ee452 in _UIApplicationHandleEvent()
#4 0x32031425 in PurpleEventCallback()
#5 0x30235253 in CFRunLoopRunSpecific()
#6 0x302343c8 in CFRunLoopRunInMode()
#7 0x308e6209 in -[UIApplication _run]()
#8 0x308eef81 in UIApplicationMain()
#9 0x000023ef in main (argc=1, argv=0xbffff0bc) at /Users/tomen/Documents/MIB-Sprint4/main.m:26
時NSZombieEnabled設置爲YES這只是發生。如果沒有設置，應用程序只運行（並在不同時間崩潰）
我想添加諸如「 - [_ NSZombie methodSignatureForSelector：]」等斷點，但它們在調試期間取消激活。我試着用「加載符號懶惰」打開和關閉兩種方式。
我也試過了我的〜/ .gdbinit中設置爲
fb -[NSException raise]
fb -[NSAssertionHandler handleFailureInFunction:file:lineNumber:description:]
fb -[NSAssertionHandler handleFailureInMethod:object:file:lineNumber:description:]
#define NSZombies
# this will give you help messages. Set to NO to turn them off.
set env MallocHelp=YES
# might also be set in launch arguments.
set env NSZombieEnabled=YES
set env NSDeallocateZombies=NO
set env MallocCheckHeapEach=100000
set env MallocCheckHeapStart=100000
set env MallocScribble=YES
set env MallocGuardEdges=YES
set env MallocCheckHeapAbort=1
set env CFZombie 5
fb -[_NSZombie init]
fb -[_NSZombie retainCount]
fb -[_NSZombie retain]
fb -[_NSZombie release]
fb -[_NSZombie autorelease]
fb -[_NSZombie methodSignatureForSelector:]
fb -[_NSZombie respondsToSelector:]
fb -[_NSZombie forwardInvocation:]
fb -[_NSZombie class]
fb -[_NSZombie dealloc]
fb szone_error
其產生這樣的結果在控制檯：
The Debugger has exited with status 0.

爲什麼我的斷點得到解除？
