Tested Environments

ALMoviePlayerController has been tested to work on iOS 5.0, 5.1 and 6.0 (simulator), and iOS 6.1 and 7.0 (device). ALMoviePlayerController requires that ARC be enabled.

ALMoviePlayerController在iOS5.0,iOS5.1以及6.0,7.0上测试过,ALMoviePlayerController需要开启ARC.

Example Usage

The process is as follows:

使用流程:

1. Create an ALMoviePlayerController movie player and assign yourself as its delegate 创建出实例对象并设置好代理
2. Create the ALMoviePlayerControls controls (and optionally customize) 创建出ALMoviePlayerControls(可选)
3. Assign the controls to the movie player 将控制器赋值给播放器
4. Set the movie player‘s contentURL, which will start playing the movie 设置好电影播放的文件URL地址,用以控制电影开始播放
5. On device rotation, adjust movie player frame if it‘s not in fullscreen (when in fullscreen, rotation is handled automatically)
6. Implement ALMoviePlayerController delegate methods 实现ALMoviePlayerController代理方法

In code:

@property (nonatomic, strong) ALMoviePlayerController *moviePlayer;

//...

// create a movie player
self.moviePlayer = [[ALMoviePlayerController alloc] initWithFrame:self.view.frame];
self.moviePlayer.delegate = self; //IMPORTANT!

// create the controls
ALMoviePlayerControls *movieControls = [[ALMoviePlayerControls alloc] initWithMoviePlayer:self.moviePlayer style:ALMoviePlayerControlsStyleDefault];

// optionally customize the controls here...
/*
[movieControls setBarColor:[UIColor colorWithRed:195/255.0 green:29/255.0 blue:29/255.0 alpha:0.5]];
[movieControls setTimeRemainingDecrements:YES];
[movieControls setFadeDelay:2.0];
[movieControls setBarHeight:100.f];
[movieControls setSeekRate:2.f];
 */

// assign the controls to the movie player
[self.moviePlayer setControls:movieControls];

// add movie player to your view
[self.view addSubview:self.moviePlayer.view];

//set contentURL (this will automatically start playing the movie)
[self.moviePlayer setContentURL:[NSURL URLWithString:@"http://archive.org/download/WaltDisneyCartoons-MickeyMouseMinnieMouseDonaldDuckGoofyAndPluto/WaltDisneyCartoons-MickeyMouseMinnieMouseDonaldDuckGoofyAndPluto-HawaiianHoliday1937-Video.mp4"]];

On rotation:

if (!self.moviePlayer.isFullscreen) {
    [self.moviePlayer setFrame:frame];
    //"frame" is whatever the movie player‘s frame should be at that given moment
}

Note: you MUST use [ALMoviePlayerController setFrame:] to adjust frame, NOT[ALMoviePlayerController.view setFrame:]

Delegate methods

@required
- (void)moviePlayerWillMoveFromWindow;

@optional
- (void)movieTimedOut;

Note: moviePlayerWillMoveFromWindow is required for fullscreen mode to work properly. It should be used to re-add the movie player to your view controller‘s view (because during the transition to fullscreen, it was moved to [[UIApplication sharedApplication] keyWindow].

Your code might look something like this:

- (void)moviePlayerWillMoveFromWindow {
    if (![self.view.subviews containsObject:self.moviePlayer.view])
        [self.view addSubview:self.moviePlayer.view];

    [self.moviePlayer setFrame:frame];
}

Controls Properties

ALMoviePlayerControls has the following editable properties:

/**
 The style of the controls. Can be changed on the fly.

 Default value is ALMoviePlayerControlsStyleDefault
 */
@property (nonatomic, assign) ALMoviePlayerControlsStyle style;

/**
 The state of the controls.
 */
@property (nonatomic, readonly) ALMoviePlayerControlsState state;

/**
 The color of the control bars. 

 Default value is black with a hint of transparency.
 */
@property (nonatomic, strong) UIColor *barColor;

/**
 The height of the control bars. 

 Default value is 70.f for iOS7+ and 50.f for previous versions.
 */
@property (nonatomic, assign) CGFloat barHeight;

/**
 The amount of time that the controls should stay on screen before automatically hiding.

 Default value is 5 seconds.
 */
@property (nonatomic, assign) NSTimeInterval fadeDelay;

/**
 The rate at which the movie should fastforward or rewind.

 Default value is 3x.
 */
@property (nonatomic, assign) float seekRate;

/**
 Should the time-remaining number decrement as the video plays?

 Default value is NO.
 */
@property (nonatomic) BOOL timeRemainingDecrements;

/**
 Are the controls currently showing on screen?
 */
@property (nonatomic, readonly, getter = isShowing) BOOL showing;

Controls Styles

typedef enum {
    /** Controls will appear in a bottom bar */
    ALMoviePlayerControlsStyleEmbedded,

    /** Controls will appear in a top bar and bottom bar */
    ALMoviePlayerControlsStyleFullscreen,

    /** Controls will appear as ALMoviePlayerControlsStyleFullscreen when in fullscreen and ALMoviePlayerControlsStyleEmbedded at all other times */
    ALMoviePlayerControlsStyleDefault,

    /** Controls will not appear */
    ALMoviePlayerControlsStyleNone,

} ALMoviePlayerControlsStyle;
