我无法在接受的答案建议的文档中找到代码，但我在此处找到了更新的等效内容：文件系统编程指南::访问文件和目录»- (NSURL*)applicationDataDirectory { NSFileManager* sharedFM = [NSFileManager defaultManager]; NSArray* possibleURLs = [sharedFM URLsForDirectory:NSApplicationSupportDirectory inDomains:NSUserDomainMask]; NSURL* appSupportDir = nil; NSURL* appDirectory = nil; if ([possibleURLs count] >= 1) { // Use the first directory (if multiple are returned) appSupportDir = [possibleURLs objectAtIndex:0]; } // If a valid app support directory exists, add the // app's bundle ID to it to specify the final directory. if (appSupportDir) { NSString* appBundleID = [[NSBundle mainBundle] bundleIdentifier]; appDirectory = [appSupportDir URLByAppendingPathComponent:appBundleID]; } return appDirectory;}它不鼓励使用NSSearchPathForDirectoriesInDomain：NSSearchPathForDirectoriesInDomains函数的行为类似于URLForDirectory：inDomains：方法，但将目录的位置作为基于字符串的路径返回。您应该使用URLForDirectory：inDomains：方法。以下是一些其他有用的目录常量。毫无疑问，iOS中并不支持所有这些功能。您还可以使用NSHomeDirectory（）函数：在iOS中，主目录是应用程序的沙箱目录。在OS X中，它是应用程序的沙箱目录或当前用户的主目录（如果应用程序不在沙箱中）来自NSPathUtilities.hNSApplicationDirectory = 1, // supported applications (Applications) NSDemoApplicationDirectory, // unsupported applications, demonstration versions (Demos) NSDeveloperApplicationDirectory, // developer applications (Developer/Applications).
