Generate CSV sample iphone app/code

Question

Does anyone have a sample app or some sample code to generate a CSV file on iOS?

Answer 1

Following code I used for generating CSV.

   NSMutableString *mainString=[[NSMutableString alloc]initWithString:@""];
    for(int i=0;i<[commentArray count];i++ ) {
        NSString *string=[[commentArray objectAtIndex:i]objectForKey:@"cmtName"]; 
        string=[string stringByReplacingOccurrencesOfString:@"\"" withString:@"\"\""];
        [mainString appendFormat:@"\"%@\"",string];

        string=[[commentArray objectAtIndex:i]objectForKey:@"cmtDesc"];  
        string=[string stringByReplacingOccurrencesOfString:@"\"" withString:@"\"\""];
        [mainString appendFormat:@",\"%@\"",string];

        string=[[commentArray objectAtIndex:i]objectForKey:@"cmtType"];
        string=[string stringByReplacingOccurrencesOfString:@"\"" withString:@"\"\""];
        [mainString appendFormat:@",\"%@\"",string];

        [mainString appendFormat:@",\"%@\"",string];
        [mainString appendFormat:@"\n"];
    }


    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,  NSUserDomainMask, YES);
    NSString *documentsDirectoryPath = [paths objectAtIndex:0];
    NSString *filePath = [documentsDirectoryPath  stringByAppendingPathComponent:@"Docment.conf"];


    NSData* settingsData;
    settingsData = [mainString dataUsingEncoding: NSASCIIStringEncoding];

    if ([settingsData writeToFile:filePath atomically:YES])
        NSLog(@"writeok");

And for importing CSV you use this
