我正在尝试创建一个目录
NSError*error=nil;
NSString* BIDirectory=[[NSSearchPathForDirectoriesInDomains(NSCachesDirectory,NSUserDomainMask,YES) objectAtIndex:0] stringByAppendingPathComponent:@"BI"];
BOOL isDir,flag=YES;
//if the directory doesn't exist create it.
if(!([[NSFileManager defaultManager] fileExistsAtPath:BIDirectory isDirectory:&isDir]&& isDir))
flag=[[NSFileManager defaultManager] createDirectoryAtURL:[NSURL URLWithString:BIDirectory] withIntermediateDirectories:YES attributes:nil error:&error];
我收到以下错误
enter code hereError Domain=NSCocoaErrorDomain Code=518 "The operation couldn’t be completed. (Cocoa error 518.)" UserInfo=0x197190 {NSURL=/var/mobile/Applications/55793654-6CDB-4B07-8FBF-553DC37D583D/Library/Caches/BI}
也许网址是错的？
