I am working on barcode app.So when user enter barcode in textfield so when it match (-)insert in that string like this let suppose textfield.text =12345786 so when it match it converted into 1234-5786 it is inserted but not deleting from my textfield.text value when my text is 123457869 or 1234578 dash(-)is not removing and textfield.text becomes 1234----. here is my code tell me where i am doing wrong? NSMutableString *a = [NSMutableString stringWithString:textfield.text];
if([textfield.text floatValue]>=8 ){
[a insertString: @"-" atIndex: 4];
//textfield.text = [textfield.text stringByReplacingOccurrencesOfString:@"-" withString:@""];
textfield.text = a;
NSLog(@"in if");
}
else if([textfield.text length]<8){
//[a insertString: @"" atIndex: 4];
textfield.text = [textfield.text stringByReplacingOccurrencesOfString:@"-" withString:@""];
NSLog(@"in else");
//NSRange range = {4,5};
//[a deleteCharactersInRange:range];
//textfield .text = a;
}

NSString *abc=@"12345678";
NSString * a =[abc substringWithRange:NSMakeRange(0, 4)];
NSString *b =[abc substringWithRange:NSMakeRange(0, 8)];
abc =[NSString stringWithFormat:@"%@-%@",a,b];
NSLog(@"%@",abc);
