Question

I have the following output to the console saying that this class is a __NSCFConstantString

NSLog(@"select category instance %@", [[SelectCategory instance] getCategoryText].class);

the output of that the string is: bar|cafe|grocery_or_supermarket|liquor_store|night_club

how do I extract just the first category? (The categories are separated by “|“) In this case it would be “bar“. I then need to store that in a variable.

thanks for any help

Since __NSCFConstantString is an NSString, you can use the componentsSeparatedByString: method:

NSString *all = [[SelectCategory instance] getCategoryText];
NSString *first = [[all componentsSeparatedByString:@"|"] objectAtIndex:0];
