iOS的本地推送UILocalNotification的使用

UILocalNotification

 

 

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:@"name"forKey:@"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 UIApplication
UIApplication *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 取消推送
[app cancelLocalNotification:localNotification];
[localNotification release];

return;
}

}


}
