IOS开发—本地推送

来源：互联网发布：appium python client 编辑：程序博客网时间：2024/05/19 11:20

思路介绍

主要考虑以下点

如何设置推送（包括推送内容、推送时间、推送周期等）
如何接收推送考虑3种情况
1. app在前台运行
2. app未关闭,在后台运行
3. app关闭
接收到推送后如何响应（主要的用户交互在这里）
如何移除本地推送

代码说明

注册本地通知

/*! *  注册本地通知 */+ (void)registerLocalNotification{    //初始化本地通知    UILocalNotification *localNotification = [[UILocalNotification alloc]init];    //触发通知时间    localNotification.fireDate = [NSDate dateWithTimeIntervalSinceNow:6]; //6s后触发通知    //时区    localNotification.timeZone = [NSTimeZone defaultTimeZone];    //触发通知后弹出警告框中显示的内容    localNotification.alertBody = @"这是一个本地通知";    //触发通知时的声音(这里使用系统的声音)    localNotification.soundName = UILocalNotificationDefaultSoundName;    //设置在app icon右上角显示的未读标识    NSInteger badgeNumber = [UIApplication sharedApplication].applicationIconBadgeNumber;    localNotification.applicationIconBadgeNumber = badgeNumber+1;    //设置通知的用户信息（可以用于移除通知，也可以传其他的值到获取通知的方法中）    localNotification.userInfo = @{@"key":@"notification1"};    //ios8后，需要先注册通知类型，才能得到授权    if ([[UIApplication sharedApplication] respondsToSelector:@selector(registerUserNotificationSettings:)]) {        UIUserNotificationType type =  UIUserNotificationTypeAlert | UIUserNotificationTypeBadge | UIUserNotificationTypeSound;        UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:type categories:nil];        [[UIApplication sharedApplication] registerUserNotificationSettings:settings];        //触发通知的频率(是一个枚举变量，可以设置每分、每时、每天等)        localNotification.repeatInterval = NSCalendarUnitDay;    } else {        //触发通知的频率(是一个枚举变量，可以设置每分、每时、每天等)        localNotification.repeatInterval = NSDayCalendarUnit;    }    //执行通知计划    [[UIApplication sharedApplication] scheduleLocalNotification:localNotification];}

不同情况下本地推送的接收及响应

/*! *  接收到本地通知时的回调(有两种情况会在这里接收到通知推送。一、app在前台运行；二、app在后台运行,用户点击通知栏通知切回前台。注意：如果app在后台运行，用户接收到推送的通知，不是点击通知，而是点击app图标切回到app，是不会触发这个回调的) */- (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification{    NSLog(@"----------------%@",notification);    //接收到通知后的交互    UIAlertView *alert = [[UIAlertView alloc]initWithTitle:nil message:notification.alertBody delegate:nil cancelButtonTitle:@"确定" otherButtonTitles: nil];    [alert show];    //更新未读标识    NSInteger badge = [UIApplication sharedApplication].applicationIconBadgeNumber;    NSLog(@"%zi",badge);    badge--;    badge = badge >= 0 ? badge : 0;    [UIApplication sharedApplication].applicationIconBadgeNumber = badge;    //根据需要移除通知    [ViewController removeLocalNotificationForName:@"notification1"];    // do something else}

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {    // Override point for customization after application launch.    //当app在关闭情况下接收到本地推送通知时，点击通知栏对应的通知启动app会调用此方法,此时通过langchOptions参数可以获取到记载了本地通知的相关信息。如果是通过点击app图标启动app,也会调用这个方法，但是launchOptions通过UIApplicationLaunchOptionsLocalNotificationKey关键字获取到的本地通知信息为空。    UILocalNotification *localNotification = [launchOptions objectForKey: UIApplicationLaunchOptionsLocalNotificationKey];    if (localNotification) {        //获取本地通知详细信息        NSDictionary *userInfo = localNotification.userInfo;        //通过信息判断为哪条本地通知, 做出相应回应        NSString *key = [userInfo objectForKey:@"key"];        if ([key isEqualToString:@"notification1"]) {            //更新未读标识            NSInteger badge = [UIApplication sharedApplication].applicationIconBadgeNumber;            badge--;            badge = badge >= 0 ? badge : 0;            [UIApplication sharedApplication].applicationIconBadgeNumber = badge;            //接收到通知后的交互            UIAlertView *alert = [[UIAlertView alloc]initWithTitle:nil message:@"Mark" delegate:nil cancelButtonTitle:@"确定" otherButtonTitles: nil];            [alert show];            //根据需要移除通知            [ViewController removeLocalNotificationForName:@"notification1"];            // do something else        }    }    return YES;}

移除本地推送

/*! *  移除本地通知 *  [[UIApplication sharedApplication] cancelAllLocalNotifications]; 可以移除所有本地推送 * *  @param notificationName 本地通知自定义的名字标识 */+ (void)removeLocalNotificationForName:(NSString *)notificationName{    if (!notificationName) {        return;    }    //获取所有本地通知    NSArray *arrayNotifications = [UIApplication sharedApplication].scheduledLocalNotifications;    //遍历所有通知 根据名字标识移除指定通知    for (UILocalNotification *localNotification in arrayNotifications) {        NSDictionary *dic = localNotification.userInfo;        if ([[dic objectForKey:@"key"] isEqualToString:notificationName]) {            [[UIApplication sharedApplication] cancelLocalNotification:localNotification];            NSLog(@"通知 %@ 已移除",notificationName);        }    }}
