视频直播项目中添加了一个新功能，接收推送后进入到主播的房间，在这里做下笔记，写在前边，项目中我使用的推送是友盟，版本是V1.4.0，适配了iOS10，下面开始。
接入友盟推送
推荐看下这篇文章，写的很详细，在这里只补充一点。在一开始做好的时候我这里有时能获取到token，有时获取不到，如果你也有这种情况，试试下面这个图中的方法
接收推送消息后跳转到某个页面
iOS10以前使用- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo这个方法接收推送消息
iOS10以后则是使用
-(void)userNotificationCenter:(UNUserNotificationCenter *)center willPresentNotification:(UNNotification *)notification withCompletionHandler:(void (^)(UNNotificationPresentationOptions))completionHandler
和
-(void)userNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void (^)())completionHandler
这两种方法接收，这两个的区别我在代码里做了注释。
在appdelegate.h文件中生成一个协议和一个属性
//协议
@protocol getBaseurlDelegate <NSObject>
-(void)didGetPushNotifi;
@end
//属性
@property (nonatomic,strong) NSDictionary* userInfo; //友盟推送信息，跳转到指定房间
@property (nonatomic,strong) id<getBaseurlDelegate> delegate; //代理
在appdelegate.m中
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
//...其它处理
//友盟推送跳转到指定房间
NSDictionary* userInfo = [launchOptions objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey];
if(userInfo){//推送信息
self.userInfo = userInfo;//[userInfo copy]
}
return YES;
}
//iOS10以下使用这个方法接收通知
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
{
_userInfo = userInfo;
//关闭友盟自带的弹出框
[UMessage setAutoAlert:YES];
[UMessage didReceiveRemoteNotification:userInfo];
// self.userInfo = userInfo;
//定制自定的的弹出框
if([UIApplication sharedApplication].applicationState == UIApplicationStateActive)
{
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"标题"
message:@"Test On ApplicationStateActive"
delegate:self
cancelButtonTitle:@"不去"
otherButtonTitles:@"去看看",nil];
[alertView show];
}
}
/*
应用没启动(后台没有应用)
应用没启动(后台没有应用)而且锁屏状态下
didReceiveNotificationResponse
应用启动了但是在后台
didReceiveNotificationResponse
应用启动了而且在应用内
willPresentNotification
*/
//iOS10新增：处理前台收到通知的代理方法 在程序内
-(void)userNotificationCenter:(UNUserNotificationCenter *)center willPresentNotification:(UNNotification *)notification withCompletionHandler:(void (^)(UNNotificationPresentationOptions))completionHandler{
NSDictionary * userInfo = notification.request.content.userInfo;
_userInfo = userInfo;
if([notification.request.trigger isKindOfClass:[UNPushNotificationTrigger class]]) {
//自定义弹出框
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"标题"
message:@"接收到了推送消息"
delegate:self
cancelButtonTitle:@"不去"
otherButtonTitles:@"去看看",nil];
[alertView show];
//应用处于前台时的远程推送接受
//关闭友盟自带的弹出框
[UMessage setAutoAlert:NO];
//必须加这句代码
[UMessage didReceiveRemoteNotification:userInfo];
}else{
//应用处于前台时的本地推送接受
}
//当应用处于前台时提示设置，需要哪个可以设置哪一个
completionHandler(UNNotificationPresentationOptionSound|UNNotificationPresentationOptionBadge|UNNotificationPresentationOptionAlert);
}
//iOS10新增：处理后台点击通知的代理方法 程序挂起
-(void)userNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void (^)())completionHandler{
NSDictionary * userInfo = response.notification.request.content.userInfo;
_userInfo = userInfo;
if([response.notification.request.trigger isKindOfClass:[UNPushNotificationTrigger class]]) {
//应用处于后台时的远程推送接受
//必须加这句代码
[UMessage didReceiveRemoteNotification:userInfo];
}else{
//应用处于后台时的本地推送接受
}
[self.delegate didGetPushNotifi];
}
//这里需要遵守alertview的代理，自己添加<UNUserNotificationCenterDelegate,UIAlertViewDelegate>
-(void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex{
//点击去看看
if (buttonIndex==1) {
[self.delegate didGetPushNotifi];
}
}
在viewcontroller中(我这里使用的是tab+nav)，tab加载的带nav的viewcontroller
- (void)viewDidLoad {
[super viewDidLoad];
//...其它操作
//友盟推送，跳转到指定房间,处理程序未启动(后台也没有挂起)
NSString * pushName = [[self.appDele.userInfo objectForKey:@"aps"] objectForKey:@"alert"];
if([Common isEmptyOrNull:pushName]){
[self getPushInfo:self.appDele.userInfo];
}
}
#pragma mark - appdelegate中接收到了通知进入主播房间
-(void)didGetPushNotifi{
//友盟推送，跳转到指定房间，处理程序已启动(在后台或者程序内)
NSString * pushName = [[self.appDele.userInfo objectForKey:@"aps"] objectForKey:@"alert"];
if([Common isEmptyOrNull:pushName]){
[self getPushInfo:self.appDele.userInfo];
//
}
}
上面代码中的getPushInfo方法是我做的其他操作，因为我这里要用字段访问网络获取数据，打开其它房间就可以在这里面写，给个例子吧。
-(void)getPushInfo:(NSDictionary *)userInfo{
PlayLiveViewController * PLVC = [[PlayLiveViewController alloc]init];
PLVC.hidesBottomBarWhenPushed=YES;
PLVC.type = @"push";
[PLVC getValue:hM];
[self.navigationController pushViewController:PLVC animated:YES];
}
补充下，如果要是出现崩溃的情况，请检查一下后台发送的数据的格式，有时是不要错把int当做string来处理，还有就是后台发送的数据为空的情况下也会崩溃，需要做判断处理。
