nsdataにファイルに書き込むことができないようです。私が間違っているかもしれないアイデア。前もって感謝します。

NSString* filename = @"myfile.txt";

NSString *applicationDocumentsDir = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];

NSString *storePath = [applicationDocumentsDir stringByAppendingPathComponent:filename];    

if ([fileManager fileExistsAtPath:applicationDocumentsDir])
    NSLog(@"applicationDocumentsDir exists");   // verifies directory exist

NSData *data = [NSData dataWithContentsOfURL:URL];

if (data) {    
     NSString *content = [[NSString alloc]  initWithBytes:[data bytes]
                                                      length:[data length] encoding: NSUTF8StringEncoding];

    NSLog(@"%@", content); // verifies data was downloaded correctly

    NSError* error;
    [data writeToFile:storePath options:NSDataWritingAtomic error:&error];

    if(error != nil)
        NSLog(@"write error %@", error);
}

エラーが発生し続ける

"The operation couldn’t be completed. No such file or directory"

試す 

NSString *storePath = [applicationDocumentsDir stringByAppendingPathComponent:@"myfile.txt"];

と

 if ([[NSFileManager defaultManager] fileExistsAtPath:storePath])
        NSLog(@"applicationDocumentsDir exists");
