So I have an issue with using a constant variable in the following switch statement in Objective-C. I have Constants.h with the following: // Constants.h extern NSInteger const TXT_NAME; And Constants.m as: // Constants.m #import "Constants.h" NSInteger const TXT_NAME = 1; Then in TabBasic.m I am trying to use this constant in a switch-case statement: // TabBasic.m #import "TabBasic.h" #import "Constants.h" ... code ... - (IBAction)saveValue:(id)sender { if ([sender isKindOfClass: [UITextField class]]) { UITextField *txtField = (UITextField *) sender; switch (txtField.tag) { case TXT_NAME: NSLog(@"Set property name to: %@", txtField.text); break; } } } But unfortunately it is giving me the following two errors on the "case TXT_NAME:" line: Expression is not an integer constant expression Case label does not reduce to an integer constant Does anyone know what I'm doing wrong? The "tag" variable of a UITextField returns an NSInteger, so I don't see the issue... Thanks for your help!
