ios本地推送互动

篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了ios本地推送互动相关的知识,希望对你有一定的参考价值。
? 小编只是一个小白,每个app都需要推送功能,个人觉得是基础中的基础,所以自学了下推送,并且写了点小demo,也是第一次发原创博客,还请各路大神批评指导。
信息推送可以让App尚未运行的状态下可以接受一些信息,通常的推送有苹果自带的APNS推送,这个方面的知识还请自行查询学习,本文只是针对本地推送互动方面,后续会单独写APNS推送的博文,还请持续关注!
推送信息文字主要出现四个位置:1.屏幕锁定画面;2.屏幕上方下拉的“通知区域”;3.解锁后屏幕最上方的横幅的位置;4解锁后的提示位置;解锁模式下推送信息的位置需要在自己去调整 在系统--->通知--->要调整的App下面调整
推送信息的处理有互动按钮(本文使用四个),可以把这四个按钮放在- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions 方法中,封装在UIMutableUserNOtificationCategory类中,一个App可以有很多组Category,以供推送信息时选 择,最后将category封装到NSSet中,注册到UIUserNotificationSettings中。
代码如下:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { // Override point for customization after application launch. UIMutableUserNotificationAction *action1=[UIMutableUserNotificationAction new]; action1.identifier=@"ACTION_1"; action1.title=@"title"; action1.activationMode=UIUserNotificationActivationModeForeground; action1.authenticationRequired=YES; action1.destructive=NO; UIMutableUserNotificationAction *action2=[UIMutableUserNotificationAction new]; action2.identifier=@"ACTION_2"; action2.title=@"title2"; action2.authenticationRequired=NO; action2.activationMode=UIUserNotificationActivationModeBackground; action2.destructive=YES; UIMutableUserNotificationAction *action3=[UIMutableUserNotificationAction new]; action3.identifier=@"ACTION_3"; action3.title=@"title3"; action3.activationMode=UIUserNotificationActivationModeBackground; action3.authenticationRequired=NO; action3.destructive=NO;; UIMutableUserNotificationAction *action4=[UIMutableUserNotificationAction new]; action4.identifier=@"ACTION_4"; action4.title=@"titile4"; action4.activationMode=UIUserNotificationActivationModeBackground; action4.authenticationRequired=NO; action4.destructive=NO; UIMutableUserNotificationCategory *category=[UIMutableUserNotificationCategory new]; category.identifier=@"CATEGORY"; [category setActions:@[action1,action2,action3,action4] forContext:UIUserNotificationActionContextDefault]; NSSet *categories=[NSSet setWithObject:category]; UIUserNotificationSettings *setting=[UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeAlert|UIUserNotificationTypeBadge|UIUserNotificationTypeSound categories:categories]; [application registerUserNotificationSettings:setting]; return YES; }
这 其中:identifier是用来识别用户点击了哪个按钮的;title是按钮的文字;activationMode是指这个按钮按下去是不是要把app 调到前台运行,设置为前台运行就需要赋值为YES;authenticationRequired是只当设备属于锁定状态时候,是否要求用户先解 锁;destructive是标识特别重要的按钮,操作他可能带来一定的影响,例如删除数据。
互动操作需要在appdelega.m的一个方法中写互动操作方法代码如下:
-(void)application:(UIApplication *)application handleActionWithIdentifier:(NSString *)identifier forLocalNotification:(UILocalNotification *)notification withResponseInfo:(NSDictionary *)responseInfo completionHandler:(void (^)())completionHandler { if ([notification.category isEqualToString:@"CATEGORY"]) { if ([identifier isEqualToString:@"ACTION_1"]) { NSLog(@"单击了Category1,Action1"); } if ([identifier isEqualToString:@"ACTION_2"]) { [UIApplication sharedApplication].applicationIconBadgeNumber=0; NSLog(@"单击了Category2,Action2"); } if ([identifier isEqualToString:@"ACTION_3"]) { NSLog(@"单击了Category3,Action3"); } if ([identifier isEqualToString:@"AACTION_4"]) { NSLog(@"单击了Category4,Action4"); } } completionHandler();//必写 }
最后在viewDidLoad写(图方便)
- (void)viewDidLoad { [super viewDidLoad]; // Do any additional setup after loading the view, typically from a nib. UILocalNotification *note=[UILocalNotification new]; note.alertBody=@"自定义推送通知"; note.category=@"CATEGORY"; note.applicationIconBadgeNumber=1; note.soundName=UILocalNotificationDefaultSoundName; note.fireDate=[NSDate dateWithTimeIntervalSinceNow:10]; [[UIApplication sharedApplication] scheduleLocalNotification:note]; }
谢谢!初次写,不足之处请谅解!!!
