Question

I want to write Tableview’s data into file .In tableview I have three column. how can I do that ?

Answer 1

The Data you are viewing in the Table must be coming from some Array or Dictionary.

Iterate through array or Dictionary to get each value of string (i suppose). Keep appending this values to an NSData. Then write this data to file using the method

- (BOOL)writeToFile:(NSString *)path atomically:(BOOL)useAuxiliaryFile;

Check this

 //For Array
    NSMutableArray *contentArr = [[NSMutableArray alloc] init];//your array here
    NSMutableData *bodyData = [[NSMutableData alloc] init];

    for (NSString *aStrData in contentArr) {
        [bodyData appendData:[aStrData dataUsingEncoding:NSUTF8StringEncoding]];

    }

    [bodyData writeToFile:FilePath atomically:YES];
