Please check the below code:
(void) moviePlayerDidExitFullscreen:(NSNotification*)notification
{
MPMoviePlayerController *player = [notification object];
[[NSNotificationCenter defaultCenter] removeObserver:self
name:MPMoviePlayerDidExitFullscreenNotification
object:player];
[player setControlStyle:MPMovieControlStyleNone];
if (isPlaying)
{
[self stopCurrentMoviePlayer];
}
}
The issue is that this works perfectly in IOS 5, but not working in IOS 6 updates iPad3.
The movie player is not closing after the video is complete and I need to click done button every time to close the Movie Player.
Can anyone provide a solution for this issue?
Clicking done will call moviePlayerDidExitFullscreen
But if you let the movie finish normally moviePlaybackDidFinish is called but since IOS 6 it doesn't exit you from fullscreen mode. So the fix is to add player.fullscreen = FALSE; right before calling
[player.view removeFromSuperview];

I'am trying to call a function when the app com back to Foreground by applicationDidBecomeActiveNotification. I have it in iOS 8 and iOS 7 and it works well. But not in iOS 9 ? It docent call first time you open the app
-(void) viewWillAppear:(BOOL)animated {
[[NSNotificationCenter defaultCenter]
addObserver:self
selector:#selector(applicationDidBecomeActiveNotification:)
name:UIApplicationDidBecomeActiveNotification
object:[UIApplication sharedApplication]];
}
- (void)applicationDidBecomeActiveNotification:(NSNotification *)notification {
//stuff
}
It is every notification center that is not calling at startup...
I hade the same problem and for me it worked to move the addObserver code to awakeFromNib. Another solution could be to add a delay to the addObserver as in the example below:
dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(0.5 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(applicationDidBecomeActive) name:UIApplicationDidBecomeActiveNotification object:nil];
});
See Apple Foundation update for NotificationCenter
This is what you need,
NSNotificationCenter.defaultCenter().addObserverForName(UIApplicationDidBecomeActiveNotification, object: nil, queue: nil) { note in
self.applicationDidBecomeActiveNotification(note)
}
After switching to iOS8, I'm getting weird behavior when I move views during a keyboard transition. Can anyone explain what's going on?
Here's a minimal example to demonstrate the problem. I have a simple view with a UITextField and a UIButton. The function nudgeUp moves the text field and the button up by 10 points. It is triggered either by the buttonPressed callback, or the keyboardWillShow callback.
When I tap the button, the code works as expected: buttonPressed calls nudgeUp and the button and text field jump up by 10 points.
When I tap the text field, keyboardWillShow calls nudgeUp, but the behaviour is very different. The button and text field immediately jump down by 10 points, and then slide back up to their original position as the keyboard shows itself.
Why is this happening? How can I regain control of animations during keyboard presentation in iOS8?
#import "ViewController.h"
#implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(keyboardWillShow:)
name:UIKeyboardWillShowNotification
object:nil];
}
- (void)keyboardWillShow:(NSNotification *)notification
{
// Called when the keyboard appears.
[self nudgeUp];
}
- (IBAction)buttonPressed:(id)sender {
[self nudgeUp];
}
- (void)nudgeUp
{
CGRect newTextFieldFrame = self.textField.frame;
newTextFieldFrame.origin.y -= 10;
self.textField.frame = newTextFieldFrame;
CGRect newButtonFrame = self.button.frame;
newButtonFrame.origin.y -= 10;
self.button.frame = newButtonFrame;
}
#end
It's AutoLayout. Something changed in iOS8 and you can't just change frame or center points anymore if you have AutoLayout enabled. You have to create an outlet(s) of your constraint (vertical space) and update it accordingly instead of changing frame position. Constraints are like any other ui control and can have an outlet. Constraint change can be animated.
Example:
[UIView animateWithDuration:[notification.userInfo[UIKeyboardAnimationDurationUserInfoKey] doubleValue] delay:0 options:[[[notification userInfo] objectForKey:UIKeyboardAnimationCurveUserInfoKey] integerValue] animations:^{
self.bottomSpaceConstraint.constant = adjustmentedValue;
[self.view layoutIfNeeded];
} completion:^(BOOL finished) {
}];
You should use UIKeyboardDidShowNotification (you're using will version) and everything will work as you expect:
- (void)viewDidLoad {
[super viewDidLoad];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(keyboardDidShow:)
name:UIKeyboardDidShowNotification
object:nil];
}
- (void)keyboardDidShow:(NSNotification *)notification
{
// Called when the keyboard finished showing up
[self nudgeUp];
}
The explanation is that with UIKeyboardWillShowNotification you are changing the frames too early. After your changes the system will relayout everything to accomodate the keyboard and your changes won't have any effect.
Also, I recommend you to switch to autolayout and forget about frames.
Try using the UIKeyboardWillShowNotification userInfo to give you the frame of the keyboard. Then move the onscreen elements based on that.
I was wondering how to swipe the ViewController with a visible keyboard?
in iOS 7 I can swipe the ViewController from side to side, but the keyboard stays put.
in short, I would like to get to the following state:
Thanks!
Update:
I can't recommend the original solution. While it performed well (when it performed at all), it was an unreliable hack, and could easily break the pop gesture recognizer.
My colleague Dave Lyon came up with a great solution using iOS 7 view controller transitions and packaged it up into a pod:
https://github.com/cotap/TAPKeyboardPop
Once installed, just import the main file and you should be good to go.
Original:
I'd love to know if there's a better way of doing this, but I was able to achieve the behavior by adding the keyboard's view as a subview of the view controller's main view:
- (void)viewDidLoad
{
[super viewDidLoad];
self.textView.inputAccessoryView = [UIView new];
}
- (void)viewWillAppear:(BOOL)animated
{
[super viewWillAppear:animated];
NSNotificationCenter *center = [NSNotificationCenter defaultCenter];
[center addObserver:self
selector:#selector(keyboardWillHide:)
name:UIKeyboardWillHideNotification
object:nil];
}
- (void)viewWillDisappear:(BOOL)animated
{
[super viewWillDisappear:animated];
[[NSNotificationCenter defaultCenter] removeObserver:self];
}
- (void)keyboardWillHide:(NSNotification *)note
{
if (self.textView.isFirstResponder) {
UIView *keyboardView = self.textView.inputAccessoryView.superview;
if (keyboardView) {
dispatch_async(dispatch_get_main_queue(), ^{
[self.view addSubview:keyboardView];
});
}
}
}
I've found you can also animate the keyboard with the gesture (via addTarget:action:), but the performance is abysmal and doesn't cleanly animate if the gesture is prematurely canceled.
I have a video that auto plays at launch. When the short clip is finished it shows a black screen. I would like to dismiss the subview to show an image or auto load another controller??
Below is my code:
(void)viewDidLoad
{
{
NSURL *url = [NSURL fileURLWithPath:[[NSBundle mainBundle]
pathForResource:#"cover" ofType:#"mp4"]];
MPMoviePlayerController *player = [[MPMoviePlayerController alloc]
initWithContentURL:url];
player.movieSourceType = MPMovieSourceTypeFile;
[player setControlStyle:MPMovieControlStyleNone];
player.view.frame = CGRectMake(0, 0, 768, 960);
[self.view addSubview:player.view];
[player play];
player = nil;
}
Thanks for any help..i'm a rookie at this.
I figured out a lot of this a couple of weeks ago. Check out the notifications available. http://developer.apple.com/library/ios/#documentation/mediaplayer/reference/MPMoviePlayerController_Class/Reference/Reference.html
Add something like this to viewDidLoad:
// Remove the movie player view controller from the "playback did finish" notification observers
[[NSNotificationCenter defaultCenter] removeObserver:_moviePlayer
name:MPMoviePlayerPlaybackDidFinishNotification
object:_moviePlayer];
// Register this class as an observer instead
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(movieFinishedCallback:)
name:MPMoviePlayerPlaybackDidFinishNotification
object:_moviePlayer];
Now you have a method where you can re-add the view, or a thumbnail, or whatever:
- (void)movieFinishedCallback:(NSNotification*)aNotification
{
// Obtain the reason why the movie playback finished
NSNumber *finishReason = [aNotification userInfo][MPMoviePlayerPlaybackDidFinishReasonUserInfoKey];
if ([finishReason intValue] == MPMovieFinishReasonPlaybackEnded) {
[self.view addSubview:self.moviePlayer.view];
}
(This code was adapted on the fly from my project, may need thinking to adapt!)
The MPMoviePlayerController has a lot of notifications that get fired when the movie is playing, is paused, is stopped, is finished, etc. You can add your code to those methods to get very good control of your presentation.
In my case, it took about a day of research and hacking (and maybe another half day of cleanup and tuning), but I managed to get a very nice play/pause transparent button, with a "play icon" image overlay when paused or stopped, all loading or unloading based on the player state. It's a simple custom player control that does exactly what I want. Totally doable, just start with one player state, get what you want, and move onto the next state.
I have a detail view, and when viewdidload in detailviewcontroller, MPMoviePlayerController allocs and plays an audio, but even if I navigate backto main table, audio is still being played.
How can I stop MPMovieplayercontroller when I navigate back to main table ? This is my MPMoviePlayerController code:
.h
MPMoviePlayerController *player;
.m
- (void)viewDidLoad
{
[super viewDidLoad];
//Get the Movie
NSURL *movieURL = [NSURL URLWithString:#"some link"];
player = [[MPMoviePlayerController alloc] initWithContentURL:movieURL];
//Place it in subview, else it won’t work
player.view.frame = CGRectMake(20, 20, 280, 25);
player.backgroundView.backgroundColor = [UIColor clearColor];
[self.view addSubview:player.view];
// Play the movie.
[player play];
}
I even added following code into viewdidunload method, but didn't work.
- (void)viewDidUnload {
[player stop];
player.initialPlaybackTime = -1;
[player release];
// Release any retained subviews of the main view.
// e.g. self.myOutlet = nil;
}
What do you guys suggest ?
Thanks in advance,
I liked the user experience of viewDidDisappear better than viewWillDisappear. The animation starts and the movie stops after - the audio flows better for me this way.
-(void)viewDidDisappear:(BOOL)animated {
[super viewDidDisappear:animated];
[_moviePlayer stop];
}
I am having a similar issue. I am unable to use "viewDidDisappear" or "viewWillDisappear" because I have a "config" type view that can be opened while the content is playing, and it will trigger those two methods.
EDIT: Found that viewDidUnload and viewWillUnload are not getting called any more (I'm currently on an iOS 6+ device)...
From the documentation:
Availability: iOS (3.0 and later) Deprecated: Views are no longer
purged under low-memory conditions and so this method is never called.
I just created a simple function called unload, and inside the function, set any objects I needed to = nil (I'm using ARC). At the time that I make the call to remove the view, I call the unload function as well. Hope it helps someone.
