试图获取Caches目录的内容:

NSError *error;
NSString *path = [[self.class cachesDirectoryURL] absoluteString];
NSArray *directoryItems = [[NSFileManager defaultManager] contentsOfDirectoryAtPath:path error:&error];

path是的,我可以在Finder中看到它存在并包含我的文件.
directoryItems是nil和error是

Error Domain=NSCocoaErrorDomain Code=260 "The folder “Caches” doesn’t exist." UserInfo={NSUnderlyingError=0x7982d2d0 {Error Domain=NSPOSIXErrorDomain Code=2 "No such file or directory"}, NSFilePath=file:///Users/seelts/Library/Developer/CoreSimulator/Devices/C1411C3D-91FB-4D91-83A4-D0747071AE36/data/Containers/Data/Application/800DE429-F10C-438E-BB04-2948C0B07E7C/Library/Caches/, NSUserStringVariant=(
    Folder
)}

我怎么了？
