NSDate *date = [NSDatedateWithTimeIntervalSinceNow:20];
//chuagjian一个本地推送
UILocalNotification *noti = [[[UILocalNotificationalloc] init]autorelease];
if (noti) {
//设置推送时间
noti.fireDate = date;
//设置时区
noti.timeZone = [NSTimeZonedefaultTimeZone];
//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 = [UIApplicationsharedApplication];
[appscheduleLocalNotification: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 = [[UIAlertViewalloc] initWithTitle:@"接收到本地提醒 in app"
message:notification.alertBody
delegate:nil
cancelButtonTitle:@"确定"
otherButtonTitles:nil];
[alertshow];
//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 = [UIApplicationsharedApplication];
//获取本地推送数组
NSArray *localArr = [appscheduledLocalNotifications];
//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){
[localNotirelease];
localNoti =nil;
}
localNoti = [notiretain];
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 = [[UILocalNotificationalloc] init];
}
if (localNoti && !state) {
//不推送 取消推送
[app cancelLocalNotification:localNoti];
[localNotirelease];
return;
}
}
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;
}
}
}
