IOS开发中本地消息推送方法.doc

第一步：接收本地推送实现代理方法didReceiveLocalNotification- (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification*)notification/在此时设置解析notification，并展示提示视图第二步：创建本地推送- （void）createLocalNotification / 创建一个本地推送UILocalNotification *notification = UILocalNotification alloc init autorelease;/设置10秒之后NSDate *pushDate = NSDate dateWithTimeIntervalSinceNow:10;if (notification != nil) / 设置推送时间 notification.fireDate = pushDate; / 设置时区 notification.timeZone = NSTimeZone defaultTimeZone; / 设置重复间隔 notification.repeatInterval = kCFCalendarUnitDay; / 推送声音 notification.soundName = UILocalNotificationDefaultSoundName; / 推送内容 notification.alertBody = 推送内容; /显示在icon上的红色圈中的数子 notification.applicationIconBadgeNumber = 1; /设置userinfo 方便在之后需要撤销的时候使用 NSDictionary *info = NSDictionary dictionaryWithObject:nameforKey:key; notification.userInfo = info; /添加推送到UIApplication UIApplication *app = UIApplication sharedApplication; app scheduleLocalNotification:notification; 第三步：解除本地推送- (void) removeLocalNotication / 获得 UIApplicationUIApplication *app = UIApplication sharedApplication;/获取本地推送数组NSArray *localArray = app scheduledLocalNotifications;/声明本地通知对象UILocalNotification *localNotification;if (localArray) for (UILocalNotification *noti in localArray) NSDictionary *dict = noti.userInfo; if (dict) NSString *inKey = dict objectForKey:key; if (inKey isEqualToString:对应的key值) if (localNotification) localNotification release; localNotification = nil; localNotification = noti retain; break; /判断是否找到已经存在的相同key的推送 if (!localNotification) /不存在初始化 localNotification = UILocalNotification alloc init; if (localNotification) /不推送 取
