Question

This is what I want the app to do.

Tap in a “Text View” not a “Text Field”, then the keyboard is displayed and a bullet point (“\u2022”) pops up. You type your sentence, and when you hit return it makes a new bullet.

So essentially, you have a Text View that is a bulleted list. Much like Word, where you start a bullet and when you hit return it make a new bullet for you, so you can start typing on that line.

How do I do this?

This is what worked for any other stupid noobs like me:

I put this into my .m file

-(BOOL)textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range  replacementText:(NSString *)text
{
if([text isEqualToString:@"\n"])
{
NSString *modifiedString = [myTextView.text stringByAppendingString:@"\n\u2022"];
[myTextView setText:modifiedString];
return NO;
}
return YES;
}

I put this into my .h file

@interface CRHViewController3 : UIViewController <UITextViewDelegate> {

    __weak IBOutlet UITextView *myTextView; 


} 

and then I put this under my viewDidLoad

    - (void)viewDidLoad
{
    [super viewDidLoad];

[myTextView setDelegate:self];   

}

Try out this.

(BOOL)textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range replacementText:(NSString *)text
{
    if([text isEqualToString:"\n"])
    {
        NSString *modifiedString = [textView.text stringByAppendingString:@"\n\u2022"];
        [textView setText:modifiedString];
        return NO;
    }
    return YES;
}
