Example doesn't work any more

[gradha]

The provided example doesn't compile out of the box. After adding missing files to the project it still fails at runtime with:

2013-03-01 12:12:32.071 KVOBlockBindingExample[69343:11303] -[KVOBlockBindingViewController bind:keyPath:to:keyPath:addReverseBinding:]: unrecognized selector sent to instance 0x7564cd0
2013-03-01 12:12:32.078 KVOBlockBindingExample[69343:11303] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[KVOBlockBindingViewController bind:keyPath:to:keyPath:addReverseBinding:]: unrecognized selector sent to instance 0x7564cd0'

+1
it's because of the nonexistent methods...

-(void)twoWayBinding
{
    [self bind:stepper1 keyPath:@"value" to:stepper2 keyPath:@"value" addReverseBinding:YES];

    // add one way blocks to observe the stepper values
    [self observe:stepper1 keyPath:@"value" block:^(id observed, NSDictionary *change) {       
        stepper1Label.text = [NSString stringWithFormat:@"%1.0f",stepper1.value];
    }];
    [self observe:stepper2 keyPath:@"value" block:^(id observed, NSDictionary *change) {
        stepper2Label.text = [NSString stringWithFormat:@"%1.0f",stepper2.value];
    }];

}
