Saving text file to documents directory in iOS 7

Question

I am trying to save a plain text file to the Documents directory in iOS 7. Here is my code:

//Saving file
NSFileManager *fileManager = [[NSFileManager alloc]         


        

Answer 1

Mundi's answer in Swift:

    let fileName = "/File Name.txt"
    let filePath = self.applicationDocumentsDirectory().path?.stringByAppendingString(fileName)

    do {
        try strFileContents.writeToFile(filePath!, atomically: true, encoding: NSUTF8StringEncoding)
        print(filePath)
    }
    catch {
        // error saving file
    }

func applicationDocumentsDirectory() -> NSURL {

    return NSFileManager.defaultManager().URLsForDirectory(NSSearchPathDirectory.DocumentDirectory, inDomains: NSSearchPathDomainMask.UserDomainMask).last!
}

Answer 2

From Apple's Xcode Template:

/**
 Returns the URL to the application's Documents directory.
 */
- (NSURL *)applicationDocumentsDirectory {
    return [[[NSFileManager defaultManager] URLsForDirectory:NSDocumentDirectory 
         inDomains:NSUserDomainMask] lastObject];
}

You can save like this:

NSString *path = [[self applicationDocumentsDirectory].path 
                       stringByAppendingPathComponent:@"fileName.txt"];
[sampleText writeToFile:path atomically:YES
                       encoding:NSUTF8StringEncoding error:nil];

    -(void)writeATEndOfFile:(NSString *)content2
    {
        NSArray *paths = NSSearchPathForDirectoriesInDomains
        (NSDocumentDirectory, NSUserDomainMask, YES);
        NSString *documentsDirectory = [paths objectAtIndex:0];

        //make a file name to write the data to using the documents directory:
        NSString *fileName = [NSString stringWithFormat:@"%@/textfile.txt",
                              documentsDirectory];

        if([[NSFileManager defaultManager] fileExistsAtPath:fileName])
        {
            NSFileHandle *fileHandle = [NSFileHandle fileHandleForWritingAtPath:fileName];
            [fileHandle seekToEndOfFile];
            NSString *writedStr = [[NSString alloc]initWithContentsOfFile:fileName encoding:NSUTF8StringEncoding error:nil];
            content2 = [content2 stringByAppendingString:@"\n"];
            writedStr = [writedStr stringByAppendingString:content2];

            [writedStr writeToFile:fileName
                        atomically:NO
                          encoding:NSStringEncodingConversionAllowLossy
                             error:nil];
        }
        else {
            int n = [content2 intValue];
            [self writeToTextFile:n];
        }

    }   


 -(void) writeToTextFile:(int) value{
        //get the documents directory:
        NSArray *paths = NSSearchPathForDirectoriesInDomains
        (NSDocumentDirectory, NSUserDomainMask, YES);
        NSString *documentsDirectory = [paths objectAtIndex:0];

        //make a file name to write the data to using the documents directory:
        NSString *fileName = [NSString stringWithFormat:@"%@/textfile.txt",
                              documentsDirectory];
        //create content - four lines of text
       // NSString *content = @"One\nTwo\nThree\nFour\nFive";

        NSString *content2 = [NSString stringWithFormat:@"%d",value];
        content = [content2 stringByAppendingString:@"\n"];
        //save content to the documents directory
        [content writeToFile:fileName
                  atomically:NO
                    encoding:NSStringEncodingConversionAllowLossy
                       error:nil];

    }
