ios如何将json数据调用另存为文件

Question

Any of you knows how can I save a json data call into a file?

self.results=[NSJSONSerialization
                           JSONObjectWithData:jsonData
                           options:0
                           error:&error];

I tried:

 [_results writeToFile:@"jsonFile" atomically:YES];

But I don't see the file:

NSArray * directoryContents = [[NSFileManager defaultManager] contentsOfDirectoryAtPath:directory error:&error];

file path (
    "Default-568h@2x.png",
    "Default.png",
    "Default@2x.png",
    "en.lproj",
    "Info.plist",
    "JSON Generator",
    PkgInfo
)

Any of you knows what I'm doing wrong?

I'll really appreciate your help

JSONObjectWithData returns either an NSArray , NSDictionary or nil. If not nil write it with:

- (BOOL)writeToFile:(NSString *)path atomically:(BOOL)flag
