Another: NSString Compare Not Working in Objective-C

Question

I'm trying to use the IsEqualToString method (which I have used succesfully before). But I get the following error:

-[NSCFString IsEqualToString:]: unrecognized selector sent to instance 0xa055e7b0

Here is the code:

@interface EditHabitViewController : UIViewController<UITableViewDataSource,UITableViewDelegate> {

NSString *contactId;
}
@property (nonatomic, retain) NSString *contactId;


-(void)updateContactInfo {
NSString *sSQL = @"";
NSString *sCheck= self.contactId;

// nothing to load? then leave: 
if ([sCheck IsEqualToString: @"0"]) {
    return;
} // end if

Notice that both sCheck and contactId are both declared as NSString. This is driving me crazy!

Any help would be greatly appreciated.

You have some errant capitalization in IsEqualToString:-- try isEqualToString: instead.
