Check whether NSString contains a comma (,)

Question

I have string separated by a comma. First I want to check whether or not the string contains a comma. In my app the string looks like this:

NSString *str=@"1,2,3";    

How to check whether or not it contains a comma?

Answer 1

I solved my problem by using following code:

NSString *str=@"1,2,3";
NSArray *result=[str componentsSeparatedByString:@","];
if([result count]!=0)
{
    NSLog(@"String contains comma");
}
