an IPhone OSStatus code to something useful? 15 answers I can easily find noErr = 0 in the OS X library source code. But it's pretty hard to find a full list of error code for OSStatus on iOS. On Mac OS X, it's not that hard to find stuff like kAudioHardwareUnsupportedOperationError But I can't seem to find useful info for iOS OSStatus codes. It would be nice to have a full list of them or any pointers to

the header files that define them. Thanks! UPDATE: I don't think my question is a duplicate of the above question. The op of that "possible duplicate" question wanted to convert the 4-char codes he already knew into human-readable strings. Instead, here is my further spec: I don't even know what 4-char or typedefed integers to use for iOS. I'd like to see something like a full list of codes, like you would normally see in many C++ framework/library design, e.g., an enum list, or standard exceptions, or even the OSX k-something codes, which at least can be found in the Xcode docs alone. My usecases of these codes include: In my custom functions, e.g., some CoreAudio callbacks that have to return OSStatus, I'd like to return these built-in human-readable codes to indicate the types of runtime errors. Without the list, I don't know what to return, other than noErr. Apparently, many OSX k-codes are undefined under iOS environment so they can't be used transparently. UPDATE (CONCLUSION): I finally found a clue: Search for keyword "Result Codes" in Xcode documentation (Organizer) and we get more or less categorized return codes documentation sections in the "System Guides" result. This is good enough for my original question. – ios cocoa error-handling share|improve this question edited Jun 26 '13 at 19:11 asked Jun 3 '13 at 21:26 kakyo 1,77342243 marked as duplicate by Carl Norum, mja, Trinimon, Cairn
NSError objects to convey information about runtime errors that users need to be informed about. In most cases, a program displays this error information in a dialog or sheet. osstatus error -43 foxtel go But it may also interpret the information and either ask the user

to attempt to recover from the error or attempt to correct the error on its own. The core attributes of osstatus 34018 an NSError object—or, simply, an error object—are an error domain, a domain-specific error code, and a “user info” dictionary containing objects related to the error, most significantly description and recovery strings. This http://stackoverflow.com/questions/16906111/ios-where-to-find-the-full-list-of-osstatus-codes-for-ios chapter explains the reason for error objects, describes their attributes, and discusses how you use them in Cocoa code.Why Have Error Objects?Because they are objects, instances of the NSError class have several advantages over simple error codes and error strings. They encapsulate several pieces of error information at once, including localized error strings of various kinds. NSError objects can also be archived https://developer.apple.com/library/content/documentation/Cocoa/Conceptual/ErrorHandlingCocoa/ErrorObjectsDomains/ErrorObjectsDomains.html and copied, and they can be passed around in an application and modified. And although NSError is not an abstract class (and thus can be used directly) you can extend the NSError class through subclassing.Because of the notion of layered error domains, NSError objects can embed errors from underlying subsystems and thus provide more detailed and nuanced information about an error. Error objects also provide a mechanism for error recovery by holding a reference to an object designated as the recovery attempter for the error.Error DomainsFor largely historical reasons, errors codes in OS X are segregated into domains. For example, Carbon error codes, which are typed as OSStatus, have their origin in versions of the Macintosh operating system predating OS X. On the other hand, POSIX error codes derive from the various POSIX-conforming “flavors” of UNIX, such as BSD. The Foundation framework declares in NSError.h the following string constants for the four major error domains:NSMachErrorDomainNSPOSIXErrorDomainNSOSStatusErrorDomainNSCocoaErrorDomainThe above sequence of domain constants indicates the general layering of the domains, with the Mach error domain at the lowest layer.
