Question

I’m learning Obj-C and trying to build my first apps.
I wanted to do something using UISwitch.
Sadly I have problem with checking value of this element.

I got such action:

@synthesize SwitchValue;
[...]
- (IBAction)ToggleEnabled{
if ([SwitchValue isOn]) {
    NSLog(@"Switch ON");
    // [myImageView startAnimating];
} else {
    NSLog(@"Switch OFF");
    // [myImageView stopAnimating];
}

The problem is that in logs are displayed only:

2012-02-12 13:50:56.764 App[2763:f803] Switch OFF
2012-02-12 13:50:57.965 App[2763:f803] Switch OFF
2012-02-12 13:50:58.848 App[2763:f803] Switch OFF

By each setting of toggle.
I tried conditional even with “SwitchValue.on” or “SwitchValue.enabled” but didn’t work as well.

Seems like your IBoutlet UISwitch *SwitchValue; is not connected to xib file’s Switch. Double check this and you can do this way:

- (IBAction)ToggleEnabled:(id)sender{
    UISwitch *sw = (UISwitch *)sender;
    if ([sw isOn]) {
        NSLog(@"Switch ON");

    } else {
        NSLog(@"Switch OFF");
    }
}
