之前給應(yīng)用加入一個開機的閃屏圖片,只要設(shè)置在images.xcassets哪里設(shè)置好LaunchImage的圖片,那么應(yīng)用開啟的時候就會顯示這張圖片指導(dǎo)加載完畢.

最近老板心血來潮,說要把開機圖片換成一個3秒左右的視頻.好吧,滿足一下老板的虛榮心. (雖然明天離職了,但是工作還是要做的嘛) 于是尋思著如何去實現(xiàn)它.

StackOverFlow 有一篇關(guān)于這個方法的視線思路 Emulating splash video in iOS application

我實現(xiàn)好的具體的思路大概是這樣:

1.先把LaunchImage這圖換成黑色或者刪除.
2.在載入之后調(diào)用MPMoviePlayerController播放器, 全屏播放必須隱藏進度條.

代碼如下

-(void) openAnimation{                
    NSBundle *bundle = [NSBundle mainBundle];
    if(bundle != nil)
    {
        NSURL *movieURL;
        NSString *moviePath = [bundle pathForResource:@"OpenAnimation" ofType:@"mp4"];
        if (moviePath)
        {
            movieURL = [NSURL fileURLWithPath:moviePath];
            MPMoviePlayerViewController* mMoviePlayer = [[MPMoviePlayerViewController alloc] initWithContentURL:movieURL];
            id lastRootVC = self.window.rootViewController;
            [[NSNotificationCenter defaultCenter] addObserverForName:MPMoviePlayerPlaybackDidFinishNotification  object:nil queue:[NSOperationQueue mainQueue] usingBlock:^(NSNotification *note) {
                self.window.rootViewController = lastRootVC;
            }];
            mMoviePlayer.moviePlayer.controlStyle = MPMovieControlStyleNone;
            mMoviePlayer.moviePlayer.scalingMode = MPMovieScalingModeFill;
            self.window.rootViewController = mMoviePlayer;
            NSLog(@"%@",self.window.rootViewController);
            [mMoviePlayer.moviePlayer setFullscreen:YES animated:NO];
            [mMoviePlayer.moviePlayer play];
        }
    }
}
-(BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
        [self openAnimation];
}
