Question

I want to use in my application UISegmentedControl, to make something similar to TabBar component in windows. And I use ValueChanged Handler:

- (IBAction)tabBarChange:(id)sender{
    int pageId = tabBar.selectedSegmentIndex;
    // [self switchPage:pageId];
}

switchPage is empty function now, no one line of code written.

But, when taping on SegmentedControl, EXC_BAD_ACCESS exception appears.

What I did wrong?

Answer 1

So, i understand that this method crashed:

- (IBAction)tabBarChange:(id)sender {
    [self switchPage:sender.selectedSegmentIndex];
}

If you try to make some test function without passing any argument, will it work, for example:

- (IBAction)tabBarChange:(id)sender {
    [self testFunction];
}

- (void) testFunction {
    NSLog(@"test");
}
