I use youtube-ios-player-helper: https://github.com/youtube/youtube-ios-player-helper and https://developers.google.com/youtube/v3/guides/ios_youtube_helper
I have everything working well. Video playback is fine!
BUT!
In the project settings, I turned off landscape mode.Therefore, the video only plays in portrait mode. How do I turn on landscape mode when playing video in iOS 7?
My solution:
it works for iOS 7 and iOS 8
To play a video from YouTube, I used XCDYouTubeKit (https://github.com/0xced/XCDYouTubeKit)
AppDelegate.h:
#property (nonatomic) BOOL screenIsPortraitOnly;
AppDelegate.m:
- (NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window{
if (!self.screenIsPortraitOnly) {
return UIInterfaceOrientationMaskPortrait;
}
else {
return UIInterfaceOrientationMaskAllButUpsideDown;
}
}
MYTableViewController.m:
#import "XCDYouTubeVideoPlayerViewController.h"
#import "XCDYouTubeKit.h"
#import "AppDelegate.h"
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
XCDYouTubeVideoPlayerViewController *videoPlayerViewController = [[XCDYouTubeVideoPlayerViewController alloc] initWithVideoIdentifier:myIdYoutube];
[[NSNotificationCenter defaultCenter] removeObserver:videoPlayerViewController name:MPMoviePlayerPlaybackDidFinishNotification object:videoPlayerViewController.moviePlayer];
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(videoFinished) name:MPMoviePlayerPlaybackDidFinishNotification object:videoPlayerViewController.moviePlayer];
videoPlayerViewController.modalPresentationStyle = UIModalPresentationFullScreen;
[self presentViewController:videoPlayerViewController animated:YES completion:nil];
}
-(void)videoFinished
{
AppDelegate *appDelegate = [UIApplication sharedApplication].delegate;
appDelegate.screenIsPortraitOnly = false;
[self dismissViewControllerAnimated:YES completion:NULL];
}
XCDYouTubeVideoPlayerViewController.m
#import "AppDelegate.h"
- (instancetype) initWithVideoIdentifier:(NSString *)videoIdentifier
{
AppDelegate *appDelegate = [UIApplication sharedApplication].delegate;
appDelegate.screenIsPortraitOnly = true;
if ([[[UIDevice currentDevice] systemVersion] integerValue] >= 8)
self = [super initWithContentURL:nil];
else
self = [super init];
if (!self)
return nil;
[[NSNotificationCenter defaultCenter] removeObserver:self name:UIApplicationDidEnterBackgroundNotification object:nil];
if (videoIdentifier)
self.videoIdentifier = videoIdentifier;
return self;
}
- (void) viewWillDisappear:(BOOL)animated
{
[super viewWillDisappear:animated];
AppDelegate *appDelegate = [UIApplication sharedApplication].delegate;
appDelegate.screenIsPortraitOnly = false;
if (![self isBeingDismissed])
return;
[self.videoOperation cancel];
}

Portrait App, loads video that displays in landscape.
in iOS7 all works fine (minor fix this is iOS6 too) but in iOS8 the statusbar, although showing in landscape actually shows at the size of a portrait statusbar so it only occupies the top left hand 60% of the video (if holding device in landscape).
The code I'm using is as follows:
- (void)viewDidLoad
{
[super viewDidLoad];
[planTitleLabel setText:[[ProgrammeHandler sharedHandler]
stringForElement:kPlanStringElementPlanTitle
onDay:0 inPlan:selectedPlan]];
}
- (NSUInteger)supportedInterfaceOrientations{
return 0;
}
-(void) viewDidAppear:(BOOL)animated {
[super viewDidAppear:animated];
if ([[UIDevice currentDevice].systemVersion floatValue] < 7.0) {
[[UIApplication sharedApplication] setStatusBarOrientation:UIInterfaceOrientationLandscapeRight animated:FALSE];
[[UIApplication sharedApplication] setStatusBarHidden:TRUE withAnimation:UIStatusBarAnimationNone];
}else if ([[UIDevice currentDevice].systemVersion floatValue] >= 8.0 && [[UIDevice currentDevice].systemVersion floatValue] < 9.0) {
[[UIApplication sharedApplication] setStatusBarHidden:TRUE];
}
NSString *moviePath = [[ProgrammeHandler sharedHandler] pathForAsset:kAssetVideoIntro onDay:0 forPlan:selectedPlan];
CGSize screenBounds = [[UIScreen mainScreen] bounds].size;
[whiteFadeView setFrame:CGRectMake(0, 0, screenBounds.width, screenBounds.height)];
NSURL *videoURL = [NSURL fileURLWithPath:moviePath];
moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:videoURL];
[[moviePlayer view] setBackgroundColor:[UIColor blackColor]];
[moviePlayer setControlStyle:MPMovieControlStyleNone];
[moviePlayer setScalingMode:MPMovieScalingModeAspectFill];
//For viewing partially.....
moviePlayer.view.transform = CGAffineTransformMakeRotation(M_PI/2);
[moviePlayer setScalingMode:MPMovieScalingModeAspectFill];
[movieView setAlpha:0];
[moviePlayer.view setFrame:[movieView frame]];
moviePlayer.view.backgroundColor = [UIColor blackColor];
[movieView addSubview:moviePlayer.view];
[moviePlayer prepareToPlay];
[moviePlayer play];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(playbackFinished:)
name:MPMoviePlayerPlaybackDidFinishNotification object:nil];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(hideControl)
name:MPMoviePlayerLoadStateDidChangeNotification
object:moviePlayer];
[UIView animateWithDuration:0.5f delay:0.50f

}
- (void) hideControl {
[[NSNotificationCenter defaultCenter] removeObserver:self

[moviePlayer setControlStyle:MPMovieControlStyleFullscreen];
}
I did see this question but don't think it applies in my case.
iphone: rotation in mpmovieplayercontroller?
Does any one know how to restore the statusbar to it's fullscreen 'width'?
Ok, after looking over this again today I noticed that there was an error that iOS7 seems happy with but it was correctly throwing an error in iOS8. For anyone else with the same issue:
The fix is simply to apply the transformation to the moviePlayer itself rather than the subview. e.g.
replace
moviePlayer.view.transform = CGAffineTransformMakeRotation(M_PI/2);
with
movieView.transform = CGAffineTransformMakeRotation(M_PI/2);
I present a viewcontroller to the user with a view that shows a UIButton to record a video. When the user presses the button, my app crashes with the following error:
Terminating app due to uncaught exception 'UIApplicationInvalidInterfaceOrientation', reason: 'preferredInterfaceOrientationForPresentation must return a supported interface orientation!'
My app only supports portrait orientation and the info.plist file reflects properly. I use the same code in another app, found on Ray Wenderlich's site, and it works great. The code for the .h and .m files is below. Any help would be appreciated.

Ok, here is the answer, finally.

Basically I needed to add a category to my UIImagePickerController. I tried a lot of other fixes but this worked.
You have implemented the bool for autorotation, but did not specify if it does not auto rotate what else it should do. Try the following after autorotate method.
-(NSUInteger)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskLandscapeRight | UIInterfaceOrientationMaskLandscapeLeft | UIInterfaceOrientationMaskPortrait | UIInterfaceOrientationMaskPortraitUpsideDown;
}
Please remove any of the masks you don't need from the method above and see if this works for you.
I would like to know if it's possible (and how) when the keyboard appears in the DetailView, to disable any MasterView controls until it disappears. All of this happens in a split view based app of course.
---Update for Prince's solution---
MasterViewController.h
#property (strong, nonatomic) UIView *MasterView;
MasterViewController.m
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
MasterView=self.view;
self.detailViewController = (DetailViewController *)[[self.splitViewController.viewControllers lastObject] topViewController];
self.detailViewController = (DetailViewController *)[[self.splitViewController.viewControllers lastObject] topViewController];
}
DetailViewController.m
- (BOOL)textFieldShouldBeginEditing:(UITextField *)textField
{
((MasterViewController *)self.parentViewController).MasterView.userInteractionEnabled=NO;
return YES;
}
This code as is, crashes the app with an "Unknown Selector" error.
How do i bind delegates; Don't know if that's the problem or not. Any help?
Use UITextField's delegate and also bind delegates:
- (BOOL)textFieldShouldBeginEditing:(UITextField *)textField
{
MasterView.userInteractionEnabled = NO;
.......
return YES;
}
- (BOOL)textFieldShouldReturn:(UITextField *)textField
{
MasterView.userInteractionEnabled = YES;
[textField resignFirstResponder];
return YES;
}
I found out a solution!
in MasterView viewDidLoad:
//---registers the notifications for keyboard---
// to see if keyboard is shown / not shown
[[NSNotificationCenter defaultCenter]
addObserver: self
selector:#selector(keyboardDidShow:)
name:UIKeyboardDidShowNotification
object:self.view.window];
[[NSNotificationCenter defaultCenter]
addObserver:self
selector:#selector(keyboardDidHide:)
name:UIKeyboardDidHideNotification
object:nil];
and then...:
//----------Handling Keyboard Appearence---
-(void) keyboardDidShow:(NSNotification *) notification {
[self.tableView setUserInteractionEnabled:NO];
}
//---when the keyboard disappears---
-(void) keyboardDidHide:(NSNotification *) notification {
[self.tableView setUserInteractionEnabled:YES];
}
//---before the View window disappear---
-(void) viewWillDisappear:(BOOL)animated {
//---removes the notifications for keyboard---
[[NSNotificationCenter defaultCenter]
removeObserver: self
name:UIKeyboardWillShowNotification
object:nil];
[[NSNotificationCenter defaultCenter]
removeObserver:self
name:UIKeyboardWillHideNotification
object:nil];
}
When I click “play movie” the mpmovieplayer presents itself for half a second and I see it’s loading movie and the controls are there, but then it returns to main screen without playing the video.
How do I fix this?
Edit:
I have changed code and now the player stays up but is stuck on loading, it doesn’t play movie.
IS the problem: not preparing the movie for play? Or not stopping movie in background and then restarting it?
#import "ViewController.h"
#implementation ViewController

Right now, I am developing an application which is composed of a table view, with a search bar. When someone taps on one of the rows on the table, it will load a new view that has the corresponding page. This is my code:
RootViewController.h:
#interface RootViewController : UIViewController <UITableViewDataSource, UITableViewDelegate, UISearchDisplayDelegate, UISearchBarDelegate>
{

}

// Save the state of the search UI so that it can be restored if the view is re-created.
[self setSavedSearchTerm:[[[self searchDisplayController] searchBar] text]];
[self setSearchResults:nil];
}

[array addObject:#"Hydrogen"];
[array addObject:#"Helium"];
[self setContentsList:array];
[array release], array = nil;
// Restore search term
if ([self savedSearchTerm])
{
[[[self searchDisplayController] searchBar] setText:[self savedSearchTerm]];
}
}
- (void)viewWillAppear:(BOOL)animated
{
[super viewWillAppear:animated];
[[self mainTableView] reloadData];
}
/*
// Override to allow orientations other than the default portrait orientation.

// Releases the view if it doesn't have a superview.
[super didReceiveMemoryWarning];

This code all works, perfectly, except for one flaw. When I use the search, the results appear as expected, with results matching the string that was typed in. However, when I tap on one of the rows of the search results, the corresponding XIB file does not load; instead, it loads the XIB file that corresponded with the original text in the UITableView without the search.
For example, if I were to type in the word "Helium" in the search, it would display one result saying "Helium," but when I tap into the result it loads the "Hydrogen" page, because hydrogen was the original link that was accessed when the first row was tapped.
Can anyone help me with this? I have spent many days on this code, and it is really getting frustrating.
Thank anyone out there who can help me out very, very much!
Here you go. Change your content in didSelectRowAtIndexPath to something like this:
NSArray *objectsToUse = nil;
if (tableView == [[self searchDisplayController] searchResultsTableView])
objectsToUse = [self searchResults];
else
objectsToUse = [self contentsList];
if ([[objectsToUse objectAtIndex:indexPath.row] isEqual:#"Hydrogen"])
{
Hydrogen *hydrogen = [[Hydrogen alloc] initWithNibName:#"Hydrogen" bundle:nil];
[self.navigationController pushViewController:hydrogen animated:YES];
[hydrogen release];
}
else if ([[objectsToUse objectAtIndex:indexPath.row] isEqual:#"Helium"])
{
Helium *helium = [[Helium alloc] initWithNibName:#"Helium" bundle:nil];
[self.navigationController pushViewController:helium animated:YES];
[helium release];
}
