Does Gluon Mobile have any guidance on implementing a share button? My goal is to be able to share a string containing a link to different apps on the phone. At the moment, I need this only for the iOS implementation. I was able to find this link that provides a simple way to do this in Objective-C:
- (IBAction)shareButton:(UIBarButtonItem *)sender
{
NSString *textToShare = #"Look at this awesome website for aspiring iOS Developers!";
NSURL *myWebsite = [NSURL URLWithString:#"http://www.codingexplorer.com/"];
NSArray *objectsToShare = #[textToShare, myWebsite];
UIActivityViewController *activityVC = [[UIActivityViewController alloc] initWithActivityItems:objectsToShare applicationActivities:nil];
NSArray *excludeActivities = #[UIActivityTypeAirDrop,
UIActivityTypePrint,
UIActivityTypeAssignToContact,
UIActivityTypeSaveToCameraRoll,
UIActivityTypeAddToReadingList,
UIActivityTypePostToFlickr,
UIActivityTypePostToVimeo];
activityVC.excludedActivityTypes = excludeActivities;
[self presentViewController:activityVC animated:YES completion:nil];
}
Looking at the GoNative application example on the Gluon website, it seems like I can use the above code snippet where needed as the native iOS code. Do I have to update the ios build gradle to account for the UIActivity class mentioned in the first link above?
Update*
I have been able to get this to work based on help in this question here.
However when trying to install the native library, I get this error which is understandable as self is unknown in the scope of the code. How would I be able to do this? Instantiate a popover or dialog and pass the activityVC to it?
/Users/ashishsharma/NetBeansProjects/konfamdbranch/src/ios/native/Share.m:25:6: error: use of undeclared identifier 'self' [self presentViewController:activityVC animated:YES completion:nil];
So I was able to solve this using examples on the internet (shown above) along with going through the existing code for the Barcode Scan Service. The issue I was experiencing with the above code was that the present view controller could not be found. However, looking at the bit bucket source for Barcode Scan, I was able to get the root view with the following code:
if(![[UIApplication sharedApplication] keyWindow])
{
NSLog(#"key window was nil");
return;
}
// get the root view controller
UIViewController *rootViewController = [[[UIApplication sharedApplication] keyWindow] rootViewController];
if(!rootViewController)
{
NSLog(#"rootViewController was nil");
return;
}
Then in the code snippet I placed in the question, replace self with rootViewController:
[rootViewController presentViewController:activityVC animated:YES completion:nil];
This leads to the modified code snippet:
#import <UIKit/UIKit.h>
#include "/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/System/Library/Frameworks/JavaVM.framework/Versions/A/Headers/jni.h"
JNIEXPORT void JNICALL Java_com_gluonhq_charm_down_plugins_ios_IOSShareService_shareMessage
(JNIEnv *env, jclass jClass, jstring jMessage) {
if(![[UIApplication sharedApplication] keyWindow])
{
NSLog(#"key window was nil");
return;
}
// get the root view controller
UIViewController *rootViewController = [[[UIApplication sharedApplication] keyWindow] rootViewController];
if(!rootViewController)
{
NSLog(#"rootViewController was nil");
return;
}
NSString *textToShare = #"Check out this site!";
NSURL *myWebsite = [NSURL URLWithString:#"http://www.google.com/"];
NSArray *objectsToShare = #[textToShare, myWebsite];
UIActivityViewController *activityVC = [[UIActivityViewController alloc] initWithActivityItems:objectsToShare applicationActivities:nil];
NSArray *excludeActivities = #[UIActivityTypeAirDrop,
UIActivityTypePrint,
UIActivityTypeAssignToContact,
UIActivityTypeSaveToCameraRoll,
UIActivityTypeAddToReadingList,
UIActivityTypePostToFlickr,
UIActivityTypePostToVimeo];
activityVC.excludedActivityTypes = excludeActivities;
[rootViewController presentViewController:activityVC animated:YES completion:nil];
}
Note I followed the GoNative application to generate my objective-c/ios files correctly.
This leads to a minimal functionality share implementation only because I don't have Facebook installed on the IPhone simulator.
I started a blank tvOS project and created the following code:
- (void)viewDidLoad
{
[super viewDidLoad];
AVPlayer *avPlayer = [AVPlayer playerWithURL:[NSURL URLWithString:#"http://www.myurl.com/myvideo.mp4"]];
AVPlayerLayer *avPlayerLayer = [AVPlayerLayer playerLayerWithPlayer:avPlayer];
avPlayerLayer.frame = CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height);
[self.view.layer addSublayer:avPlayerLayer];
[avPlayer play];
}
Nothing happens in the simulator though once the app loads. No video, nothing, just a blank translucent screen in my Apple TV simulator.
What's the proper way to play a sample video on app launch for an Apple TV app from an HTTP source?
I just pasted your code in my tvOS sample project, replaced the URL and ran it.
Nothing happened. Well, except for the fact that there's a log entry telling me that App Transport Security has blocked my URL request.
So I headed to the Info.plist, disabled ATS and upon next launch the video showed up just fine.
So if you're also using a non-HTTPS URL you're very likely running into this issue which is easily fixed by either using an HTTPS URL, disabling ATS completely or allowing specific non-HTTPs URLs in your Info.plist.
P.S.: I used this video for testing.
You could also use TVML and TVMLJS
https://developer.apple.com/library/prerelease/tvos/documentation/TVMLJS/Reference/TVJSFrameworkReference/
Adhere to the 'TVApplicationControllerDelegate' protocol and add some properties.
AppDelegate.h
#interface AppDelegate : UIResponder <UIApplicationDelegate, TVApplicationControllerDelegate>
...
#property (strong, nonatomic) TVApplicationController *appController;
#property (strong, nonatomic) TVApplicationControllerContext *appControllerContext;
Then add the following to 'didFinishLaunchingWithOptions'
AppDelegate.m
#define url #"http://localhost:8000/main.js"
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// Override point for customization after application launch.
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
self.appControllerContext = [[TVApplicationControllerContext alloc] init];
NSURL *javascriptURL = [NSURL URLWithString:url];
self.appControllerContext.javaScriptApplicationURL= javascriptURL;
for (id key in launchOptions) {
id val=[launchOptions objectForKey:key];
NSLog(#"key=%# value=%#", key, val);
if([val isKindOfClass:[NSString class]]) [self.appControllerContext.launchOptions objectForKey:val];
self.appController = [[TVApplicationController alloc] initWithContext:self.appControllerContext window:self.window delegate:self];
}
return YES;
}
create a folder and add the following files
main.js
index.tvml
main.js
function launchPlayer() {
var player = new Player();
var playlist = new Playlist();
var mediaItem = new MediaItem("video", "http://trailers.apple.com/movies/focus_features/9/9-clip_480p.mov");
player.playlist = playlist;
player.playlist.push(mediaItem);
player.present();
//player.play()
}
//in application.js
App.onLaunch = function(options) {
launchPlayer();
}
careful with this url in the mediaItem
Set up a template of your choice.
index.tvml
<document>
<alertTemplate>
<title>…</title>
<description>…</description>
<button>
<text>…</text>
</button>
<text>…</text>
</alertTemplate>
</document>
open terminal and navigate to this folder then run
python -m SimpleHTTPServer 8000
make sure the port here is the port in your ObjC url. The Apple examples use 9001.

One issue I ran into was trying to play a local video file. It wouldn't work and there were constraint issues etc.
It looks like you can't use python to play the videos so either try apache or link to a video on the web.
This SO answer pointed me there.
The best way to play video in your app on AppleTV is going to be AVKit's AVPlayerViewController. If you use AVKit, you get a lot of stuff for free.
https://developer.apple.com/library/ios/documentation/AVFoundation/Reference/AVPlayerViewController_Class/index.html
You simply add that player to the viewController's player property:
// instantiate here or in storyboard
AVPlayerViewController *viewController = [[AVPlayerViewController alloc] initWithNibName:nil bundle:nil];
viewController.player = player;
[self addChildViewController:viewController];
[self.view addSubview:viewController.view];
[viewController didMoveToParentViewController:self];
// setup constraints, etc.
// play the video
[player play];
Also as mentioned below, make sure the video you're trying to play is coming either from an HTTPS connection or that you've disabled App Transport Security by setting the proper flags in the plist.
I didn't like the answers which messed about with subviews etc.
For full-screen playback, I use the following (Non-ARC) code:
// Play the stream
NSString *wifiStreamAddress = #"http://yourmoviefile.m3u8";
AVPlayer *player = [[AVPlayer alloc] initWithURL: [NSURL URLWithString: wifiStreamAddress] ];
AVPlayerViewController *playerViewController = [[AVPlayerViewController alloc] init];
playerViewController.player = player;
// Keep pointers to player and controller using retained properties:
self.player = player;
self.playerViewController = playerViewController;
[player release];
[playerViewController release];
[self presentViewController: playerViewController animated: true completion: ^{
[self.player play];
}];
This works really neat, animating presentation and fading back to previous view when you tap the MENU button. Also, it works great with the remote control using all the standard functions.
Its working for me.
May be helpful for you
-(void)playAction
{
AVPlayerViewController *viewController = [[AVPlayerViewController alloc] initWithNibName:nil bundle:nil];
viewController.player = player;
[self addChildViewController:viewController];
[self.view addSubview:viewController.view];
[viewController didMoveToParentViewController:self];
// play the video
[player play];
}
Swift version
Make a PlayViewController which inherit the AVPlayerViewController.
In the viewcontroller which has play button, add such function
#IBAction func onClickPlay(sender: AnyObject) {
let playerVC = PlayerViewController()
playerVC.playVideo(urlString)
[self.presentViewController(playerVC, animated: true, completion: nil)]
}
In the PlayerViewController
func playVimeoVideo(link : String) {
player = AVPlayer(URL: NSURL(string: link)!)
player?.play()
}
Notice
The question and some answers may be a little misleading so that you might think that only the url with ".mp4" at the end can be played by the Apple TV. I believed so at the first time I saw the post. It is not true. In fact, with AVPlayerViewController you can play Vimeo streaming video! The link to the stream video is not like https://vimeo.com/92655878. It is possible to get it from Vimeo site by extracting it from a json file, which can be downloaded from this link
let link = "https://vimeo.com/api/oembed.json?url=https%3A//vimeo.com/" + videoId
To be able to get correct url for the video, you need to use the Vimeo Pro user access to get the stream link for a specific video.
I am working on small application and i am new to osx programming, i have searched all over but I didnt find how to show custom about window.
In my application i have 3 controllers one for log in and then i switch to other but third one is About but I dont know how to change when someone click on about menu, i have come to know that orderfrontstandardaboutpanel called but how i gonna use it to show my view? this is my
- (void)applicationDidFinishLaunching:(NSNotification *)aNotification
{
_accountDetails = [[NSDictionary alloc] init];
self.loginViewController = [[MTLoginViewController alloc] initWithNibName:#"MTLoginViewController" bundle:nil];
self.loginViewController.delegate = self;
// 2. Add the view controller to the Window's content view
[self.window.contentView addSubview:self.loginViewController.view];
// [self setUIWindowsFrame:self.loginViewController.view.frame];
self.loginViewController.view.frame = ((NSView*)self.window.contentView).bounds;
}
Im trying to implement your implementation to my project as a button called 'Gallery" but receive an error when trying to run the project.
My implementation file looks like this.
-(IBAction) gallery{
NSMutableArray *photos = [[NSMutableArray alloc] init];
MWPhoto *photo;
{
photo = [MWPhoto photoWithFilePath:[[NSBundle mainBundle] pathForResource:#"fans1" ofType:#"jpg"]];
photo.caption = #"My fans 1";
[photos addObject:photo];
photo = [MWPhoto photoWithFilePath:[[NSBundle mainBundle] pathForResource:#"fans2" ofType:#"jpg"]];
photo.caption = #"My fans 2";
[photos addObject:photo];
photo = [MWPhoto photoWithFilePath:[[NSBundle mainBundle] pathForResource:#"fans3" ofType:#"jpg"]];
photo.caption = #"Fans3";
[photos addObject:photo];
photo = [MWPhoto photoWithFilePath:[[NSBundle mainBundle] pathForResource:#"fans4" ofType:#"jpg"]];
photo.caption = #"Fans4";
[photos addObject:photo];
}
self.photos = photos;
// Create browser
MWPhotoBrowser *browser = [[MWPhotoBrowser alloc] initWithDelegate:self];
browser.displayActionButton = YES;
//browser.wantsFullScreenLayout = NO;
//[browser setInitialPageIndex:2];
// Show
if (_segmentedControl.selectedSegmentIndex == 0) {
// Push
[self.navigationController pushViewController:browser animated:YES];
} else {
// Modal
UINavigationController *nc = [[UINavigationController alloc] initWithRootViewController:browser];
nc.modalTransitionStyle = UIModalTransitionStyleCrossDissolve;
[self presentModalViewController:nc animated:YES];
}
}
#pragma mark - MWPhotoBrowserDelegate
- (NSUInteger)numberOfPhotosInPhotoBrowser:(MWPhotoBrowser *)photoBrowser {
return _photos.count;
}
- (MWPhoto *)photoBrowser:(MWPhotoBrowser *)photoBrowser photoAtIndex: (NSUInteger)index {
if (index < _photos.count)
return [_photos objectAtIndex:index];
return nil;
}
When I run the project but the image gallery is not displayed. Im fairly new to ioS development.If you can please point me in the right direction i will deeply appreciate it. The main goal is to have the image gallery displayed when the user touches the Gallery button.
I copied and edited the code from the MWPhotoBrowser Demo Project File I don't receive any errors but I can't get the gallery to appear once button is touched. (BTW I assigned the IBACTION to the buttons). If there is another source code or alternative Framework I can use please advise. Thanks!
Some Ideas:
1) try using 'initWithPhotos'.
2) put a breakpoint at the place you are pushing, check that the push is called.
3) check that the navigationController is not null (0x0) in debugging.
4) remember to release 'browser'.
I'm trying to create a new tab in a Safari window from Cocoa using Scripting Bridge. My code looks something like this:
SafariApplication *safari = [SBApplication applicationWithBundleIdentifier:#"com.apple.Safari"];
if ([[safari windows] count] == 0)
{
NSLog(#"No window found. Creating a new one.");
SafariDocument *newDoc = [[[safari classForScriptingClass:#"document"] alloc] init];
[[safari windows] addObject:newDoc];
[newDoc release];
}
else
{
NSLog(#"Seems we already have a safari window");
SafariTab *newTab = [[[safari classForScriptingClass:#"tab"] alloc] init];
[[[safari windows] objectAtIndex:0] addObject:newTab];
[newTab release];
}
The first part if the "if" works, creating a new window. Creating the tab does not. This gets me "-[SafariWindow addObject:]: unrecognized selector sent to instance...", so obviously that's not the way to do it. I can't figure out how windows, documents and tabs relate to each other in Safari. Any help is greatly appreciated.
Thanks,
Thor
A-ha! Creating a tab in a window is:
SafariTab *newTab = [[[safari classForScriptingClass:#"tab"] alloc] init];
[[[[safari windows] objectAtIndex:0] tabs] addObject:newTab];
[newTab release];
