how to write in append mode for text file

Question

My application navigation based. UItextView for notes UIViewController. I am writing data for text to file. Now i need to write in append mode , the below code i am tryin

Answer 1

Try this it works great

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *documentTXTPath = [documentsDirectory stringByAppendingPathComponent:@"Notes.txt"];
NSString *savedString = textview.text;

If file Does not exist create it and write to file or else its already created append to end of the file

NSFileManager *fileManager = [NSFileManager defaultManager];
if(![fileManager fileExistsAtPath:documentTXTPath])
{
  [savedString writeToFile:documentTXTPath atomically:YES];
}
else
{
  NSFileHandle *myHandle = [NSFileHandle fileHandleForWritingAtPath:documentTXTPath];
  [myHandle seekToEndOfFile];
  [myHandle writeData:[savedString dataUsingEncoding:NSUTF8StringEncoding]];
}
