首先要先设置一个继承与UIView的一个类，类中包含歌手图片，歌曲，歌手，上一曲和下一曲暂停的view －－

PlayView

然后在appdelegate中设置一个属性，属性的类属于

PlayView

在-(BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions{

self.window = [[UIWindow alloc]initWithFrame:[UIScreen mainScreen].bounds];

self.window.backgroundColor = [UIColor whiteColor];

[self.window makeKeyAndVisible];

[_window release];

NSNotificationCenter *center = [NSNotificationCenter defaultCenter];

[center addObserver:self selector:@selector(musicChange:) name:@"change" object:nil];

[center addObserver:self selector:@selector(hidden:) name:@"hidden" object:nil];

[center addObserver:self selector:@selector(didHidden:) name:@"didHidden" object:nil];

self.playView = [[PlayView alloc] initWithFrame:CGRectMake(0, self.window.frame.size.height - 60, self.window.frame.size.width, 75)];

self.playView.backgroundColor = [UIColor cyanColor];

self.playView.alpha = 0.5;

self.playView.userInteractionEnabled = YES;

UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(tap:)];

[self.playView addGestureRecognizer:tap];

}

- (void)tap:(UITapGestureRecognizer *)tap

{

self.play = [PlayViewController sharePlayVC];

[_homeview presentViewController:self.play animated:YES completion:^{

}];

}

- (void)hidden: (NSNotification*)noti

{

self.playView.hidden = NO;

}

- (void)didHidden:(NSNotification *)noti

{

self.playView.hidden = YES;

}

-(void)musicChange:(NSNotification *)noti

{

self.playView.detail = noti.object;

NSLog(@"%@",noti.object);

}

// 在播放页面的反回按钮的触发函数中载入

- (void)ReturnButton: (UIButton*)button

{

NSDictionary *notidic = [NSDictionary dictionaryWithObjectsAndKeys:@"value",@"key", nil];

[[NSNotificationCenter defaultCenter] postNotificationName:@"hidden" object:@"dddd" userInfo:notidic];

[self dismissViewControllerAnimated:YES completion:^{

}];

}

／／这样的设置可以使我们能达到想要的目的

点击底部的view弹出播放界面，播放界面会隐藏掉刚才的播放的view
