Question

As we know that it is possible to create pdf file in iphone application but i want that my data which is in table view must be saved in the documents of the application in a text file.

Answer 1

You create a text file let it be “file.txt” and write required data, here “yourString” as follows,

NSString *filePath = [documentsDirectory stringByAppendingPathComponent:@"file.txt"];
 NSString *stringWithoutSpaces = [yourString stringByReplacingOccurrencesOfString:@" " withString:@""];
[stringWithoutSpaces writeToFile:filePath atomically:TRUE encoding:NSUTF8StringEncoding error:NULL];

You can read saved data as follows,

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *documentsDirectory = [paths objectAtIndex:0];
    NSString *filePath = [documentsDirectory stringByAppendingPathComponent:@"file.txt"];
    NSString *yourString = [NSString stringWithContentsOfFile:filePath encoding:NSUTF8StringEncoding error:NULL];
