App被失活状态的时候可以走苹果的APNS；但是在活跃的时候却接受不到推送！
那就用到本地推送：UILocalNotification 消息神器。
处理不好可能会有很多本地推送到来，那么问题来了要在什么地方去注册通知？什么地方去移除通知？
一、要在什么地方去注册通知
- (void)applicationDidEnterBackground:(UIApplication *)application；
手机刚进入后台会走的方法，applicationDidEnterBackground；
我会注册一个通知：名字宏定义
/**应用获取到刷新推送消息提醒*/
#define kString_NSNotificationCenterRefreshMessageData @"kString_NSNotificationCenterRefreshMessageData"
在AppDelegate.m的 applicationDidEnterBackground方法里边添加通知
- (void)applicationDidEnterBackground:(UIApplication *)application{
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(messageCome:) name:kString_NSNotificationCenterRefreshMessageData object:nil];
}
- (void)messageCome:(NSNotification *)notifi{
if (![notifi.name isEqualToString:kString_NSNotificationCenterRefreshMessageData]) {
return;
}
dispatch_async(dispatch_get_main_queue(), ^{
[self notifi:notifi];
});
}
- (void)notifi:(NSNotification *)notifi{
NSMutableString * notifiMessage = nil;
RCMessage *message = notifi.object;
if (message.conversationType == ConversationType_SYSTEM) {
notifiMessage = [[NSMutableString alloc]initWithString: @"猎上网："];
}else if(message.conversationType == ConversationType_PRIVATE){
MessageUser *user = [[MyFMDB sharedMyFMDB] findUserWithID:[message.senderUserId intValue]];
if (user.name&&![user.name isEqualToString:@""]) {
notifiMessage = [[NSMutableString alloc]initWithString: [NSString stringWithFormat:@"%@：",user.name]];
}
}else{
return;
}
NSMutableDictionary * inforDic = [NSMutableDictionary dictionary];
UILocalNotification * locNoti = [[UILocalNotification alloc]init];
if ([message.content isKindOfClass:[RCTextMessage class]]) {
RCTextMessage *textMessage = (RCTextMessage *)message.content;
[notifiMessage appendString:textMessage.content];
[inforDic setValue:textMessage.content forKey:@"name"];
}else if([message.content isKindOfClass:[RCImageMessage class]]){
[notifiMessage appendString:@"图片"];
[inforDic setValue:@"图片" forKey:@"name"];
}else if([message.content isKindOfClass:[RCVoiceMessage class]]){
[notifiMessage appendString:@"语音"];
[inforDic setValue:@"语音" forKey:@"name"];
}else if([message.content isKindOfClass:[IMPositionMessage class]]){
[notifiMessage appendString:@"职位名片"];
[inforDic setValue:@"职位名片" forKey:@"name"];
}else if([message.content isKindOfClass:[IMSwapPhoneMessage class]]){
[notifiMessage appendString:@"交换电话"];
[inforDic setValue:@"交换电话" forKey:@"name"];
}else if([message.content isKindOfClass:[IMResumeMessage class]]){
[notifiMessage appendString:@"简历名片"];
[inforDic setValue:@"简历名片" forKey:@"name"];
}else if([message.content isKindOfClass:[TaskedPositionToHunteron class]]){
TaskedPositionToHunteron *textMessage = (TaskedPositionToHunteron *)message.content;
[notifiMessage appendString:[NSString stringWithFormat:@"PA（%@）为您定向推荐了一个新的职位（ #%lld %@）。",textMessage.paName,textMessage.positionId,textMessage.positionName]];
[inforDic setValue:textMessage.paName forKey:@"paName"];
[inforDic setValue:[NSString stringWithFormat:@"%lld",textMessage.positionId] forKey:@"positionId"];
[inforDic setValue:textMessage.positionName forKey:@"positionName"];
}
//1.1 设置通知的内容
locNoti.alertAction = notifiMessage; // 锁屏状态下显示: 滑动来快点啊
locNoti.alertBody = notifiMessage;
//1.2 设置通知的发送时间
locNoti.fireDate = [NSDate date];
locNoti.userInfo =inforDic;
//1.3 设置时区,一般默认
locNoti.timeZone = [NSTimeZone defaultTimeZone];
// 设置通知发送时, 提醒数字(==0, 会自动消失)
locNoti.applicationIconBadgeNumber = 0;
locNoti.repeatInterval = 0;
// 2. 发送通知
[[UIApplication sharedApplication]scheduleLocalNotification:locNoti];
NSLog(@"====%d",[NSThread isMainThread]);
[[UIApplication sharedApplication]cancelLocalNotification:locNoti];
}
二、什么地方去移除通知
手机刚进入前台会走的方法
- (void)applicationWillEnterForeground:(UIApplication *)application{
[[NSNotificationCenter defaultCenter] removeObserver:self name:kString_NSNotificationCenterRefreshMessageData object:nil];
}
因为手机不活跃的时候不能立即发通知！记住是立即，又不是延迟发本地推送，所以不需要处理已经不活跃的情况！要在进入前台的时候移除通知，要不然下次在进入后台会在此注册通知！就会显示两条本地推送！
