TLSignals 0.1.2

Maintained by Unclaimed.

You want to add pod 'TLSignals', '~> 0.1' similar to the following to your Podfile:

target 'MyApp' do
  pod 'TLSignals', '~> 0.1'
end

Then run a pod install inside your terminal, or from CocoaPods.app.

Alternatively to give it a test run, run the command:

pod try TLSignals

Signals for Objective-C++

Example

Let me show you how it's easy to observe some object for notifications using TLSignal. For example, we've ExampleViewController, and we would like to know when his view is loaded:

ExampleViewController.mm

#import "Signals.h"

@interface ExampleViewController : UIViewController

@property (nonatomic, readonly) TLSignal<UIView *> *viewDidLoadSignal;

@end

@implementation ExampleViewController

tl_synthesize_signal(viewDidLoadSignal, UIView *);

-(void)viewDidLoad
{
    [super viewDidLoad];
    // Notifying watchers about viewDidLoad event
    self.viewDidLoadSignal->notify(self.view);
}

@end

Easy, huh?

AppDelegate.mm

#import "AppDelegate.h"
#import "ExampleViewController.h"

@implementation AppDelegate

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)options
{
    UIWindow window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
    self.viewController = [[ExampleViewController alloc] initWithNibName:@"ExampleViewController" bundle:nil];

    // Subscribe to our event
    self.viewController.viewDidLoadSignal->addObserver(^(TLSignal<UIView *> *signal, UIView *targetView)
    {
        targetView.backgroundColor = [UIColor blackColor];
    });

    self.window.rootViewController = self.viewController;
    [self.window makeKeyAndVisible];
    return YES;
}

@end
