[contentData writeToFile:fileName atomically:YES];

}

if i write like this i got only last split file. i mean 2mb data only some one guide me how to do that?

Answer 1

Im not sure whether writeToFile works in this scenario,

But to add a file in appending mode use the following code,

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *documentTXTPath = [documentsDirectory stringByAppendingPathComponent:@"Notes.txt"];
NSString *savedString = textview.text;
NSFileHandle *myHandle = [NSFileHandle fileHandleForWritingAtPath:logPath];
[myHandle seekToEndOfFile];
[myHandle writeData:[savedString dataUsingEncoding:NSUTF8StringEncoding]];

Remove the code,

[contentData writeToFile:fileName atomically:YES];
