本文為大家分解介紹了iOS本地推送代碼的三步驟，供大家參考，具體內容如下

第一步：創建本地推送

// 創建一個本地推送
UILocalNotification *notification = [[[UILocalNotification alloc] init] autorelease];
//設置10秒之後
NSDate *pushDate = [NSDate dateWithTimeIntervalSinceNow:10];
if (notification != nil) {
 // 設置推送時間
 notification.fireDate = pushDate;
 // 設置時區
 notification.timeZone = [NSTimeZone defaultTimeZone];
 // 設置重復間隔
 notification.repeatInterval = kCFCalendarUnitDay;
 // 推送聲音
 notification.soundName = UILocalNotificationDefaultSoundName;
 // 推送內容
 notification.alertBody = @"推送內容";
 //顯示在icon上的紅色圈中的數子
 notification.applicationIconBadgeNumber = 1;
 //設置userinfo 方便在之後需要撤銷的時候使用
 NSDictionary *info = [NSDictionary dictionaryWithObject:@"name"forKey:@"key"];
 notification.userInfo = info;
 //添加推送到UIApplication  
 UIApplication *app = [UIApplication sharedApplication];
 [app scheduleLocalNotification:notification]; 
 
}

第二步：接收本地推送

- (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification*)notification{
 UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"iWeibo" message:notification.alertBody delegate:nil cancelButtonTitle:@"確定" otherButtonTitles:nil];
 [alert show];
 // 圖標上的數字減1
 application.applicationIconBadgeNumber -= 1;
}

第三步：解除本地推送

// 獲得 UIApplication
UIApplication *app = [UIApplication sharedApplication];
//獲取本地推送數組
NSArray *localArray = [app scheduledLocalNotifications];
//聲明本地通知對象
UILocalNotification *localNotification;
if (localArray) {
 for (UILocalNotification *noti in localArray) {
  NSDictionary *dict = noti.userInfo;
  if (dict) {
   NSString *inKey = [dict objectForKey:@"key"];
   if ([inKey isEqualToString:@"對應的key值"]) {
    if (localNotification){
     [localNotification release];
     localNotification = nil;
    }
    localNotification = [noti retain];
    break;
   }
  }
 }
 
 //判斷是否找到已經存在的相同key的推送
 if (!localNotification) {
  //不存在初始化
  localNotification = [[UILocalNotification alloc] init];
 }
 
 if (localNotification) {
  //不推送 取消推送
  [app cancelLocalNotification:localNotification];
  [localNotification release];
  return;
 }
}
