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;
}
}
}
