How to get data to write to a text file? - objective-c

Question

Here is the method that I'm using for a console output. How can I output to a text file?
#implementation GetMoves
- (id)initWithDevice:(Device *)device{
if(self = [super init]){
_device = device;
}
return self;
}
- (void)Render{
[super ClearConsole];
printf("MOVES INFO\n");
printf("==================================\n");
NSArray* data = [_device GetData:NULL];
NSDateFormatter* dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:#"yyyy-MM-dd HH:mm:ss"];
if(data != nil){
for(int i = 0; i < data.count; i++){
DataPoint* current = [data objectAtIndex:i];
NSMutableString* output = [[NSMutableString alloc] init];
[output appendFormat:#"%d",(i+1)];
[output appendString:#" - "];
[output appendString:[dateFormatter stringFromDate:current.RecordedAt]];
[output appendString:#" - "];
[output appendFormat:#"%d",current.StepCount];
printf("%s\n", [output UTF8String]);
}
}
else
printf("No new data found on device.\n");
printf("\n");
printf("==================================\n");
printf("\n");
printf("Press ENTER to continue.");
fgetc(stdin);
}
#end

You can simply write as :
NSString *path = [#"~" stringByExpandingTildeInPath] ;
//change your path here
path=[path stringByAppendingString:#"/Documents/*REPORTS/"];
//make a file name to write the data to using the documents directory:
NSString *fileName = [NSString stringWithFormat:#"%#/TWCodeFile.txt",path];
//create content - four lines of text
NSString *content = #"The content of file, can be more by appending string.";
//save content to the documents directory
[content writeToFile:fileName
atomically:NO
encoding:NSStringEncodingConversionAllowLossy
error:nil];
