ios-debugbar

No Maintenance Intended

Simply swipe down with 2 fingers to show a debug bar with customizable buttons. I use it for example to create or delete test data, force a reload, clean the cache, etc.

Screenshots

Example

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
#if DEBUG
    [[KRDebugBar sharedInstance] setup];

    [[KRDebugBar sharedInstance] addButtonWithTitle:@"Action 1" action:^{
        NSLog(@"Pressed action 1");
    }];

    [[KRDebugBar sharedInstance] addButtonWithTitle:@"Action 2" action:^{
        NSLog(@"Pressed action 2");
    }];

    [[KRDebugBar sharedInstance] addButtonWithTitle:@"Action 3" action:^{
        NSLog(@"Pressed action 3");
    }];

    [[KRDebugBar sharedInstance] addButtonWithTitle:@"Action 4" action:^{
        NSLog(@"Pressed action 4");
    }];

    [[KRDebugBar sharedInstance] addButtonWithTitle:@"Action 5" action:^{
        NSLog(@"Pressed action 5");
    }];
#endif

    return YES;
}

Custom activation methods

The default activation method is a two finger swipe down, but this is easily changed:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // ...
    [[KRDebugBar sharedInstance] setupWithDelegate:self];
    // ...
    return YES;
}

- (void)debugBar:(KRDebugBar *)debugBar addActivationMethodToWindow:(UIWindow *)window {
    UILongPressGestureRecognizer *longPress = [[UILongPressGestureRecognizer alloc] initWithTarget:self action:@selector(longPressed:)];
    longPress.numberOfTouchesRequired = 3;
    [window addGestureRecognizer:longPress];
}

- (void)longPressed:(UIGestureRecognizer *)sender {
    if (sender.state == UIGestureRecognizerStateBegan) {
        [[KRDebugBar sharedInstance] toggle];
    }
}

You could also very easily add shake detection by adding this to your AppDelegate:

- (BOOL)canBecomeFirstResponder {
    return YES;
}

- (void)motionBegan:(UIEventSubtype)motion withEvent:(UIEvent *)event {
    if (event.subtype==UIEventSubtypeMotionShake) {
        [[KRDebugBar sharedInstance] toggle];
    }
}

Notes and to-do's

Please note that there are some issues with this project that still need to be solved:

  • The debug bar doesn't handle rotations. Same goes for the direction of the two-finger swipe gesture.
  • The two-finger swipe down gesture doesn't play nice with tables, scroll views, collection views, etc. It's probably best to enable shake detection instead of relying on the default gesture.
