1、增加一个本地推送
//设置20秒之后
NSDate *date = [NSDate dateWithTimeIntervalSinceNow:20];
//chuagjian一个本地推送
UILocalNotification *noti = [[UILocalNotification alloc] init];
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;
}
}
