Hello i have a textview with text I want to move cursor position at beginning I have use NSMakeRange but i don't know why its not working. I have written NSMakeRange is different places , hoping that it would run atleast once but didn't work. Here is the code. thx in advance
- (void)viewDidLoad
{
[super viewDidLoad];
apnatxtView.textColor=[UIColor lightGrayColor];
apnatxtView.text=#"Description goes here";
totalLenght=apnatxtView.text.length;
apnatxtView.selectedRange=NSMakeRange(0,0);
}
- (BOOL)textViewShouldBeginEditing:(UITextView *)textView{
apnatxtView.selectedRange=NSMakeRange(0,0);
return YES;
}
- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{
[apnatxtView resignFirstResponder];
}
- (void)textViewDidChange:(UITextView *)textView{
if (apnatxtView.text.length == 0) {
apnatxtView.textColor= [UIColor lightGrayColor];
apnatxtView.text=#"Description goes here";
apnatxtView.selectedRange=NSMakeRange(0, 0);
}
}
- (BOOL)textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range replacementText:(NSString *)text
{
if (apnatxtView.textColor == [UIColor lightGrayColor]) {
apnatxtView.textColor=[UIColor blackColor];
// apnatxtView.text=#"Description goes here";
apnatxtView.text=nil;
return YES;
}
}

Answer 1

This works in my testing on the iOS 6.0 simulator:
- (void)textViewDidBeginEditing:(UITextView *)textView {
dispatch_async(dispatch_get_main_queue(), ^{
textView.selectedRange = NSMakeRange(0, 0);
});
}
I guess it updates the selection based on the touch location after it sends the textViewDidBeginEditing: message. The dispatch_async works around that.

K i found the solution. Im setting the cursor position before cursor appears I cut and paste the code in KeyBoardDidShow notification and it worked pretty fine.
