How to Choose position to print a string in a text?

Question

I’m developing an app where the user can choose in the middle of a text, the position where the output value of a string should be printed. Example: Normally when we print a string in the middle of a text we do so:

 NSLog (@" Um texto com:%@", minhaVariavelString);

Or when we use an Uitextfield:

_meuTextField.text = [NSString stringWithFormat: @"Meu valor:%@.", minhaString];

Maintaining the position of %@ fixed.

However I want to be able to provide the user with the possibility to change the output position of the string on a text composition screen when the app is running.

Just create a NSMutableString and use the method insertString:AtIndex:.

Example:

NSMutableString *vitima = [NSMutableString stringWithString:@"Minha String Legal"];
NSLog(@"%@", vitima); //Imprime "Minha String Legal"
[vitima insertString:@"Não tão " atIndex:13];
NSLog(@"%@", vitima); //Imprime "Minha String Não tão Legal"
