本地通知UILocalNotification
NSDate *date = [NSDate dateWithTimeIntervalSinceNow:20];
//chuagjian一个本地推送
UILocalNotification *noti = [[[UILocalNotification alloc] init] autorelease];
if (noti) {
//设置推送时间
noti.fireDate = date;
//设置时区
noti.timeZone = [NSTimeZone defaultTimeZone];
//设置重复间隔
noti.repeatInterval = NSWeekCalendarUnit;
//推送声音
noti.soundName = UILocalNotificationDefaultSoundName;
//内容
noti.alertBody = @"推送内容";
//显示在icon上的红色圈中的数子
noti.applicationIconBadgeNumber = 1;
//设置userinfo 方便在之后需要撤销的时候使用
NSDictionary *infoDic = [NSDictionary dictionaryWithObject:@"name" forKey:@"key"];
noti.userInfo = infoDic;
//添加推送到uiapplication
UIApplication *app = [UIApplication sharedApplication];
[app scheduleLocalNotification:noti];
}
2、程序运行时接收到本地推送消息
- (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification*)notification
{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"接收到本地提醒 in app"
message:notification.alertBody
delegate:nil
cancelButtonTitle:@"确定"
otherButtonTitles:nil];
[alert show];
//这里,你就可以通过notification的useinfo,干一些你想做的事情了
application.applicationIconBadgeNumber -= 1;
}
3、取消一个本地推送
UIApplication *app = [UIApplication sharedApplication];
//获取本地推送数组
NSArray *localArr = [app scheduledLocalNotifications];
//声明本地通知对象
UILocalNotification *localNoti;
if (localArr) {
for (UILocalNotification *noti in localArr) {
NSDictionary *dict = noti.userInfo;
if (dict) {
NSString *inKey = [dict objectForKey:@"key"];
if ([inKey isEqualToString:key]) {
if (localNoti){
[localNoti release];
localNoti = nil;
}
localNoti = [noti retain];
break;
}
}
}
//判断是否找到已经存在的相同key的推送
if (!localNoti) {
//不存在 初始化
localNoti = [[UILocalNotification alloc] init];
}
if (localNoti && !state) {
//不推送 取消推送
[app cancelLocalNotification:localNoti];
[localNoti release];
return;
}
}
- 第一步:创建本地推送
- // 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:@"确定" otherButtonTitles:nil];
- [alert show];
- // 图标上的数字减1
- application.applicationIconBadgeNumber -= 1;
- }
- 第三步:解除本地推送
- // 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;
- }
- }
