Hi all,
I am new to Cocoa programming and am trying to do something that I thought was straightforward but not working. I am using the tag field of a button to tell me what button is pushed. This code does not work
- (IBAction) numberPressed:(id)sender {
NSLog(@"Sender tag is:%d", [sender tag]);
if ([sender tag] << 10) {
displayValues.rawNumber = [displayValues.rawNumber stringByAppendingString:[NSString stringWithFormat:@"%d", [sender tag]]];
}
buttons with tags 1-9 work great but the button with tag 0 does not. When I pass tag 0 the if statement is evaluated as false.
When I press button with tag 1 I get "Sender tag is:1" and the if statement is evaluated as true.
When I press button with tag 0 I get "Sender tag is:0" and the if statement is evaluated as false.
What is going wrong here?
