AirPlay

需求:绕过系统限制,自动选择支持AirPlay的设备

Airplay基础知识

要调用出AirPlay列表需要使用到MPVolumeView控件,当系统检测到网络环境中有支持AirPlay的设备时才会出现AirPlay图标,用户点击这个图标,呼出支持AirPlay的设备列表。

 MPVolumeView *volumView = [[MPVolumeView alloc] initWithFrame:CGRectMake(60, 100, 40, 40)];
[volumView setRouteButtonImage:[UIImage imageNamed:@"pic-02"] forState:UIControlStateNormal];
volumView.showsVolumeSlider = NO;

setRouteButtonImage 自定义AirPlay图标

自动选择AirPlay设备

自动选择AirPlay设备要使用了MediaPlayer.framework的私用类MPAVRoutingController,在这里可以搜到iOS所有的framework的头文件。

Class MPAVRoutingController = NSClassFromString(@"MPAVRoutingController");
self.routerController = [[MPAVRoutingController alloc] init];
[self.routerController setValue:self forKey:@"delegate"];
[self.routerController setValue:[NSNumber numberWithLong:2] forKey:@"discoveryMode"];

NSClassFromString 获取MPAVRoutingController 类定义,并通过KVC给它的属性赋值,discoveryMode 为2时才能及时在AirPlay设备发生变化时触发它协议的-(void)routingControllerAvailableRoutesDidChange:(id)arg1;方法

-(void)routingControllerAvailableRoutesDidChange:(id)arg1{
    if (self.deviceName == nil) {
        return;
    }
    NSArray *availableRoutes = [self.routerController valueForKey:@"availableRoutes"];
    for (id router in availableRoutes) {
        NSString *routerName = [router valueForKey:@"routeName"];
        if ([routerName rangeOfString:self.deviceName].length >0) {
            BOOL picked = [[router valueForKey:@"picked"] boolValue];
            if (picked == NO) {
                [self.routerController performSelector:@selector(pickRoute:) withObject:router];
            }
            return;
        }
    }
}

MPAVRoutingControllerDelegateroutingControllerAvailableRoutesDidChange用代码来选择用户指定的AirPlay设备,如果用户想取消自动选择的功能,将deviceName属性赋值为nil即可。
