通過UILocalNotification 實現(xiàn)本地通知的推送

1 創(chuàng)建通知

UILocalNotification *notification = [[UILocalNotification alloc] init];
notification.fireDate = [NSDate dateWithTimeIntervalSinceNow:10];  
notification.alertTitle = @"打開廣播";
notification.alertBody = @"廣播";
notification.repeatInterval = NSCalendarUnitSecond;
//設置本地通知的時區(qū)
notification.timeZone = [NSTimeZone defaultTimeZone];
//設置角標的個數(shù)
notification.applicationIconBadgeNumber=1;
    
notification.userInfo = @{@"info":@"broadcast"};
notification.soundName = UILocalNotificationDefaultSoundName;

2 取消通知

UIApplication *app = [UIApplication sharedApplication];
NSArray *array = [app scheduledLocalNotifications];        
for (UILocalNotification * local in array) {
    NSDictionary *dic = local.userInfo;
    if ([dic[@"info"]  isEqual: @"broadcast"]) {
        //刪除指定的通知
        [app cancelLocalNotification:local];
    }
}
//也可以使用[app cancelAllLocalNotifications]刪除所有通知;

3 app跳出到后臺時，可在下列方法內(nèi)添加通知提示

- (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification；

4 app處于運行階段時

- (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification {
    //判斷應用程序當前的運行狀態(tài)是否為激活狀態(tài)
    if (application.applicationState == UIApplicationStateActive) {
        //只有激活狀態(tài) 在app運行時本地通知才有效
    }
}
