Ios 是什么导致了iPad2OS6.1上的SEGV_ACCERR崩溃

我的应用程序随机崩溃。这是其中一个崩溃日志： 0 libobjc.A.dylib 0x3c2075b0 objc_msgSend (in libobjc.A.dylib) + 16 1 UIKit 0x362d8d88 _UIGestureRecognizerSendActions (in UIKit) + 128 2 UIKit 0x362a03f4 -[UIGestureRecognizer _updateGestureWithEvent:] (in UIKit) + 392 3 UIKit 0x3648da38 _UIGestureRecognizerUpdate_block_invoke_0543 (in UIKit) + 48 4 UIKit 0x361c482e _UIGestureRecognizerRemoveObjectsFromArrayAndApplyBlocks (in UIKit) + 218 5 UIKit 0x361c3292 _UIGestureRecognizerUpdate (in UIKit) + 1274 6 UIKit 0x361ce1e6 -[UIWindow _sendGesturesForEvent:] (in UIKit) + 766 7 UIKit 0x361cddb2 -[UIWindow sendEvent:] (in UIKit) + 90 8 UIKit 0x361bb800 -[UIApplication sendEvent:] (in UIKit) + 380 9 UIKit 0x361bb11a _UIApplicationHandleEvent (in UIKit) + 6154 10 GraphicsServices 0x37eaf5a2 _PurpleEventCallback (in GraphicsServices) + 590 11 GraphicsServices 0x37eaf1d2 PurpleEventCallback (in GraphicsServices) + 34 12 CoreFoundation 0x34388172 __CFRUNLOOP_IS_CALLING_OUT_TO_A_SOURCE1_PERFORM_FUNCTION (in CoreFoundation) + 34 13 CoreFoundation 0x34388116 __CFRunLoopDoSource1 (in CoreFoundation) + 138 14 CoreFoundation 0x34386f98 __CFRunLoopRun (in CoreFoundation) + 1384 15 CoreFoundation 0x342f9ebc CFRunLoopRunSpecific (in CoreFoundation) + 356 16 CoreFoundation 0x342f9d48 CFRunLoopRunInMode (in CoreFoundation) + 104 17 GraphicsServices 0x37eae2ea GSEventRunModal (in GraphicsServices) + 74 18 UIKit 0x3620f300 UIApplicationMain (in UIKit) + 1120 19 MyHD 0x0000394e main (in MyHD) (main.m:15) 0 libobjc.A.dylib 0x3c2075b0 objc_msgSend（在libobjc.A.dylib中）+16 1 UIKit 0x362d8d88 _uigestureRecognitizerSendActions（在UIKit中）+128 2 UIKit 0x362a03f4-[UIGestureRecognitor _updateGestureWithEvent:（在UIKit中）+392 3 UIKit 0x3648da38\u UIGEstiureRecognitizer更新\u块\u调用\u 0543（在UIKit中）+48 4 UIKit 0x361c482e _uigestureRecognitzerRemoveObjectsFromarrayandApplyBlock（在UIKit中）+218 5 UIKit 0x361c3292 _UIGEstiureRecognitzerUpdate（在UIKit中）+1274 6 UIKit 0x361ce1e6-[UIWindow\u sendGesturesForEvent:（在UIKit中）+766 7 UIKit 0x361cddb2-[UIWindow sendEvent:（在UIKit中）+90 8 UIKit 0x361bb800-[UIApplication sendEvent:（在UIKit中）+380 9 UIKit 0x361bb11a _UIKit中的UIApplicationHandleEvent）+6154 10个图形服务0x37eaf5a2 _PurpleEventCallback（图形服务中）+590 11图形服务0x37eaf1d2 PurpleEventCallback（图形服务中）+34 12 CoreFoundation 0x34388172\uuu CFRUNLOOP\u正在调用\uu来执行\u SOURCE1\u函数（在CoreFoundation中）+34 13 CoreFoundation 0x34388116 _ucfrunloopdosource1（在CoreFoundation中）+138 14 CoreFoundation 0x34386f98 _ucfrunlooprun（在CoreFoundation中）+1384 15 CoreFoundation 0x342f9ebc CFRunLoopRunSpecific（在CoreFoundation中）+356 16 CoreFoundation 0x342f9d48 CFRunLoopRunInMode（在CoreFoundation中）+104 17图形服务0x37eae2ea GSEventRunModal（图形服务中）+74 18 UIKit 0x3620f300 UIApplicationMain（在UIKit中）+1120 19 MyHD 0x0000394e干管（在MyHD中）（干管m:15）
