我有委托(delegate)@property(nonatomic,assign)iddelegate;但它在performSelector上崩溃if(_delegate!=nil&&[_delegateconformsToProtocol:@protocol(DelegateProtocol)]){NSObject*obj=_delegate;//HEREISEXC_BAD_ACCESS[objperformSelectorOnMainThread:@selector(didTouchImageView:)withObject:selfwaitUntilDone:NO];}我在这里设
我在使用SocketRocket时收到iOSEXC_BAD_ACCESS错误,我想知道我可以做些什么来进一步调试问题以确定问题是在我这边还是在SocketRocket那边。我得到的堆栈跟踪是:Crashed:com.apple.main-threadEXC_BAD_ACCESSKERN_INVALID_ADDRESSat0x2000000craw0libobjc.A.dylibobjc_msgSend+51OMlearningsSRWebSocket.mline692__30-[SRWebSocket_failWithError:]_block_invoke_22libdispatch
这是我遇到的一个有趣的快速问题。考虑以下类和协议(protocol):classPerson{}protocolParentwhereSelf:Person{funcspeak()}classGrandMotherPerson:Person,Parent{funcspeak(){print("IamaGrandmotherPerson")}}classGrandFatherPerson:Person,Parent{funcspeak(){print("IamaGrandfatherPerson")}}letgmp=GrandMotherPerson()letgfp=GrandFathe
我有下面的代码,用来获取一个已经归档的对象的路径letpaths=NSSearchPathForDirectoriesInDomains(NSSearchPathDirectory.DocumentDirectory,NSSearchPathDomainMask.UserDomainMask,true)letpath=paths[0]asStringletarchivePath=path.stringByAppendingString("archivePath")当我运行这段代码时,它在显示lldb的NSSearchPathForDirectoriesInDomains调用时崩溃Thr
这是整个崩溃日志。EXC_CORPSE_NOTIFY异常通知是什么意思?我必须替换一些关于我们公司的字符串。IncidentIdentifier:40BD3A10-43A5-4F0D-A283-218E1D3BEE46CrashReporterKey:3d8d75a8f5eeb7c3d28d52883b92ed4e0fb2529eHardwareModel:iPhone7,1Process:XxxxxXxxApp[13539]Path:/private/var/mobile/Containers/Bundle/Application/148C5049-8883-4E9D-BB98-54
我有一个删除空日志目录的方法,然后在下一步中用符号链接(symboliclink)替换它。directory"#{ENV['GS_HOME']}/logs/"doaction:deleteonly_if{::Dir.exists?("#{ENV['GS_HOME']}/logs/")}end它第一次工作,但在下一次chef-client运行时,当它不应该删除现在链接到另一个目录的项目时,我收到一个错误:Errno::ENOTDIR--------------Notadirectory@dir_s_rmdir...为什么守卫似乎将链接视为目录而不是跳过,但资源操作正确识别它,而不是一个,
我关注了"HowITest"screencastatRailsCasts,但是我遇到了spork的问题$guardGuardisnowwatchingat'/Users/darth/projects/auth-before'StartingSporkforTest::Unit&RSpecCouldn'tfindasupportedtestframeworkthatbeginswith'testunit'Supportedtestframeworks:()Cucumber(*)RSpecLegend:()-notdetectedinproject(*)-detectedUsingRSpe

用于保护std::mutex的c++11mutexRAII类型都有一个typedef:typedefMutexmutex_type;std::lock_guard::mutex_typestd::unique_lock::mutex_typestd::scoped_lock::mutex_type这个成员typedef有什么意义?起初我认为它可以用来概括创建一个对象来移动锁(在unique_lock的情况下)例如:templatevoidfunction(SomeLockin)SomeLock::mutex_typenewMutex;//Dosomething但我无法想象它的用途。需要
