  1 第一步：接收本地推送  2   3 實現代理方法didReceiveLocalNotification  4   5     - (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification*)notification{  6   7 //在此時設定解析notification，並展示提示視圖  8   9 } 10  11 第二步：建立本地推送 12 - （void）createLocalNotification { 13  14 // 建立一個本地推送 15  16  17 UILocalNotification *notification = [[[UILocalNotification alloc] init] autorelease]; 18  19  20  21 //設定10秒之後 22  23  24  25 NSDate *pushDate = [NSDate dateWithTimeIntervalSinceNow:10]; 26  27 if (notification != nil) { 28  29 // 設定推送時間 30  31 notification.fireDate = pushDate; 32  33   // 設定時區 34  35 notification.timeZone = [NSTimeZone defaultTimeZone]; 36  37 // 設定重複間隔 38  39 notification.repeatInterval = kCFCalendarUnitDay; 40 // 推送聲音 41 notification.soundName = UILocalNotificationDefaultSoundName; 42 // 推送內容 43 notification.alertBody = @"推送內容"; 44 //顯示在icon上的紅色圈中的數子 45 notification.applicationIconBadgeNumber = 1; 46 //設定userinfo 方便在之後需要撤銷的時候使用 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 // 獲得 UIApplication 67 UIApplication *app = [UIApplication sharedApplication]; 68  69 //擷取本地推送數組 70 NSArray *localArray = [app scheduledLocalNotifications]; 71  72  73  74 //聲明本地通知對象 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:@"對應的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 //判斷是否找到已經存在的相同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 }
