Answer 1

You can try my library. I built this for my apps maybe helpful for you too.

Apple TV Project (Receiver)

Step 1: Create a TvOS Project and import the files from RemoteReceiver

libRemoteReceiver.a

RemoteReceiver.h

Step 2: In your ViewController.m file import the RemoteReceiver.h file

#import "RemoteReceiver.h"

Step 3: Inside ViewController.m file add the following code

@interface ViewController () 
@property (nonatomic, strong) RemoteReceiver *remoteReceiver;
@end

Step 4: Inside viewDidLoad alloc and set the delegate for remoteReceiver

self.remoteReceiver = [[RemoteReceiver alloc] init];
self.remoteReceiver.delegate = self;

Step 5: Implement the following delegate method for messages send from iOS remote app

-(void) didReceiveMessage:(NSDictionary *)userInfo{
    NSLog(@"%@",userInfo);
}

iOS Project (Sender/Remote Control)

Step 1: Create an iOS Project and import the files from RemoteSender

libRemoteSender.a

RemoteSender.h

Step 2: Import the RemoteSender class in your ViewController

#import "RemoteSender.h"

Step 3: Update ViewController.m with the following code

@interface ViewController ()
@property(nonatomic, strong) RemoteSender *remoteSender;
@end

Step 4: Allocate and initialize the remoteSender object

self.remoteSender = [[RemoteSender alloc] init];

Step 5: Implement gestures and methods (Check below for just button code)

- (IBAction)sendSomeInformation:(id)sender {
    NSDictionary *theDictionaryToSendToTV = @{@"name": @"John Smith",@"age": @"35", @"address":@"123 Main St"};
    [self.remoteSender sendInfo:theDictionaryToSendToTV];
}
