Solution 1
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0]; // Get documents directory
NSError *error;
BOOL succeed = [myString writeToFile:[documentsDirectory stringByAppendingPathComponent:@"myfile.txt"]
atomically:YES encoding:NSUTF8StringEncoding error:&error];
if (!succeed){
// Handle error here
}
Solution 2
Something like this:
NSString *homeDirectory;
homeDirectory = NSHomeDirectory(); // Get app's home directory - you could check for a folder here too.
BOOL isWriteable = [[NSFileManager defaultManager] isWritableFileAtPath: homeDirectory]; //Check file path is writealbe
// You can now add a file name to your path and the create the initial empty file
[[NSFileManager defaultManager] createFileAtPath:newFilePath contents:nil attributes:nil];
// Then as a you have an NSString you could simple use the writeFile: method
NSString *yourStringOfData;
[yourStringOfData writeToFile: newFilePath atomically: YES];

He is how to save NSString into Documents folder. Saving other types of data can be also realized that way.
- (void)saveStringToDocuments:(NSString *)stringToSave {
NSString *documentsFolder = [NSHomeDirectory() stringByAppendingPathComponent:@"Documents"];
NSString *fileName = [NSString stringWithString:@"savedString.txt"];
NSString *path = [documentsFolder stringByAppendingPathComponent:fileName];
[[NSFileManager defaultManager] createFileAtPath:path contents:[stringToSave dataUsingEncoding:NSUTF8StringEncoding] attributes:nil];
}
