iOS的本地推送UILocalNotification的使用

UILocalNotification

 

 

  1 第一步：接收本地推送
  2 
  3 实现代理方法didReceiveLocalNotification
  4 
  5     - (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification*)notification{
  6 
  7 //在此时设置解析notification，并展示提示视图
  8 
  9 }
 10 
 11 第二步：创建本地推送
 12 - （void）createLocalNotification {
 13 
 14 // 创建一个本地推送
 15 
 16 
 17 UILocalNotification *notification = [[[UILocalNotification alloc] init] autorelease];
 18 
 19 
 20 
 21 //设置10秒之后
 22 
 23 
 24 
 25 NSDate *pushDate = [NSDate dateWithTimeIntervalSinceNow:10];
 26 
 27 if (notification != nil) {
 28 
 29 // 设置推送时间
 30 
 31 notification.fireDate = pushDate;
 32 
 33   // 设置时区
 34 
 35 notification.timeZone = [NSTimeZone defaultTimeZone];
 36 
 37 // 设置重复间隔
 38 
 39 notification.repeatInterval = kCFCalendarUnitDay;
 40 // 推送声音
 41 notification.soundName = UILocalNotificationDefaultSoundName;
 42 // 推送内容
 43 notification.alertBody = @"推送内容";
 44 //显示在icon上的红色圈中的数子
 45 notification.applicationIconBadgeNumber = 1;
 46 //设置userinfo 方便在之后需要撤销的时候使用
 47 
 48 NSDictionary *info = [NSDictionary dictionaryWithObject:@"name"forKey:@"key"];
 49 
 50 notification.userInfo = info;
 51 
 52 //添加推送到UIApplication
 53 
 54 UIApplication *app = [UIApplication sharedApplication];
 55 
 56 [app scheduleLocalNotification:notification];
 57 
 58 }
 59 
 60 }
 61 
 62 第三步：解除本地推送
 63 
 64  - (void) removeLocalNotication {
 65 
 66 // 获得 UIApplication
 67 UIApplication *app = [UIApplication sharedApplication];
 68 
 69 //获取本地推送数组
 70 NSArray *localArray = [app scheduledLocalNotifications];
 71 
 72 
 73 
 74 //声明本地通知对象
 75 UILocalNotification *localNotification;
 76 
 77 if (localArray) {
 78 
 79 for (UILocalNotification *noti in localArray) {
 80 
 81 NSDictionary *dict = noti.userInfo;
 82 
 83 if (dict) {
 84 
 85 NSString *inKey = [dict objectForKey:@"key"];
 86 
 87 if ([inKey isEqualToString:@"对应的key值"]) {
 88 
 89 if (localNotification){
 90 
 91 [localNotification release];
 92 
 93 localNotification = nil;
 94 }
 95 
 96 localNotification = [noti retain];
 97 
 98 break;
 99 
100 }
101 
102 }
103 
104 }
105 
106 
107 //判断是否找到已经存在的相同key的推送
108 if (!localNotification) {
109 
110 //不存在初始化
111 localNotification = [[UILocalNotification alloc] init];
112 
113 }
114 if (localNotification) {
115 //不推送 取消推送
116 [app cancelLocalNotification:localNotification];
117 [localNotification release];
118 
119 return;
120 }
121 
122 }
123 
124 
125 }
