set the cursor position on textview

Question

I want to to set the cursor position based on the x,y coordinates on the text view. For example I want cursor position on (10,5,300,462), I want to insert the text this frame only based on cursor.

In view did load i set the delegate and use the NSMakeRange() function

- (void)viewDidLoad
    {
        [super viewDidLoad];
         _TextView.delegate=self;
           _TextView.editable = YES;
          [_TextView setSelectedRange:NSMakeRange(5,0)];
    }

I create a text view with frame of (10,22,300,462) and added to the view. My reqirement is i want display the cursor on text base on x,y coordinates x=10 after and y=5 after in the text view ...

hello stack overflow community. i hope i don't answer to late.

- (NSUInteger) textOffsetFromPoint: (CGPoint *) position
{
    // this gives you the nearest UITextPosition
    UITextPosition * closestPosition = [textView closestPositionToPoint:tapPoint];

    // and this "translate" UITextPosition into an integer
    NSUInteger offset = [textView offsetFromPosition:textView.beginningOfDocument 
                                          toPosition:closestPosition];
    return offset;
}

then the code suggested by Sunny.

[self performSelector:@selector(setCursorPosition:) withObject:textView afterDelay:0.01];

- (void)setCursorPosition:(UITextView *)textview
{
    textview.selectedRange = NSMakeRange([self textOffsetFromPoint:position], 0);
}

Look UITextInput Protocol Reference for more information.
