ios7 - I want to add a space in between a string in objective c - 


- (ibaction)addspace:(id)sender { //here nospce textbox in enter value     nsstring *one=self.nospace.text;      if (one.length==4)     //if length of string equal 4 should put whitespace      //in between string.     {         nsstring *blank=@"  ";         nsstring *two=[blank. stringbyappendingstring:one,index(2)];         nsstring *new=two;    //here withspace textbox in want show expected result             self.withspace.text=new;         }  //this not work me

nsstring *two=[blank. stringbyappendingstring:one,index(2)];

there's extraneous . after blank in method call. remove , index(2) , code should work better.

your code improved using mutable string. use -insertstring:atindex: , avoid need intermediate strings.

update: should change name of new variable. new name of method in nsobject, , reserved word in c++. using variable name should work, it's bound lead confusion in future.
