Question

I have a one NSString & I want to remove some characters from it, when the first comma is found in it.

ex. str = @"0,1,2,3"; 
output - > str = @"1,2,3";

How to do this. Can anyone help me please to sort out this issue.

Answer 1

The generic case:

NSString* str= @"0,1,2,3";
NSRange range= [str rangeOfString: @","];
if(range.location!=NSNotFound)
{
    str= [str substringWithRange: NSMakeRange(range.location+1, str.length-range.length-1)];
    NSLog(@"%@",str);
}

It doesn’t create a crash if the string hasn’t a comma.
