ios - NSFileManager创建目录错误518 NSFileWriteUnsupportedSchemeError

我试图创建一个目录

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}

网址可能不正确？

最佳答案

代替

    [NSURL URLWithString:BIDirectory]

请用

    [NSURL fileURLWithPath:BIDirectory]

在本地文件上使用URLWithString:BIDirectory是错误的
