App被失活狀態的時候可以走蘋果的APNS；但是在活躍的時候卻接受不到推送！
那就用到本地推送：UILocalNotification 消息神器。
處理不好可能會有很多本地推送到來，那么問題來了要在什么地方去注冊通知？什么地方去移除通知？
一、要在什么地方去注冊通知
- (void)applicationDidEnterBackground:(UIApplication *)application；
手機剛進入后台會走的方法，applicationDidEnterBackground；
我會注冊一個通知：名字宏定義
/**應用獲取到刷新推送消息提醒*/
#define kString_NSNotificationCenterRefreshMessageData @"kString_NSNotificationCenterRefreshMessageData"
在AppDelegate.m的 applicationDidEnterBackground方法里邊添加通知
- (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: @"獵上網："];
}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:@"圖片"];
[inforDic setValue:@"圖片" forKey:@"name"];
}else if([message.content isKindOfClass:[RCVoiceMessage class]]){
[notifiMessage appendString:@"語音"];
[inforDic setValue:@"語音" forKey:@"name"];
}else if([message.content isKindOfClass:[IMPositionMessage class]]){
[notifiMessage appendString:@"職位名片"];
[inforDic setValue:@"職位名片" forKey:@"name"];
}else if([message.content isKindOfClass:[IMSwapPhoneMessage class]]){
[notifiMessage appendString:@"交換電話"];
[inforDic setValue:@"交換電話" forKey:@"name"];
}else if([message.content isKindOfClass:[IMResumeMessage class]]){
[notifiMessage appendString:@"簡歷名片"];
[inforDic setValue:@"簡歷名片" forKey:@"name"];
}else if([message.content isKindOfClass:[TaskedPositionToHunteron class]]){
TaskedPositionToHunteron *textMessage = (TaskedPositionToHunteron *)message.content;
[notifiMessage appendString:[NSString stringWithFormat:@"PA（%@）為您定向推薦了一個新的職位（ #%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 設置通知的內容
locNoti.alertAction = notifiMessage; // 鎖屏狀態下顯示: 滑動來快點啊
locNoti.alertBody = notifiMessage;
//1.2 設置通知的發送時間
locNoti.fireDate = [NSDate date];
locNoti.userInfo =inforDic;
//1.3 設置時區,一般默認
locNoti.timeZone = [NSTimeZone defaultTimeZone];
// 設置通知發送時, 提醒數字(==0, 會自動消失)
locNoti.applicationIconBadgeNumber = 0;
locNoti.repeatInterval = 0;
// 2. 發送通知
[[UIApplication sharedApplication]scheduleLocalNotification:locNoti];
NSLog(@"====%d",[NSThread isMainThread]);
[[UIApplication sharedApplication]cancelLocalNotification:locNoti];
}
二、什么地方去移除通知
手機剛進入前台會走的方法
- (void)applicationWillEnterForeground:(UIApplication *)application{
[[NSNotificationCenter defaultCenter] removeObserver:self name:kString_NSNotificationCenterRefreshMessageData object:nil];
}
因為手機不活躍的時候不能立即發通知！記住是立即，又不是延遲發本地推送，所以不需要處理已經不活躍的情況！要在進入前台的時候移除通知，要不然下次在進入后台會在此注冊通知！就會顯示兩條本地推送！
