在ios 9中设置应用程序徽章编号 [英] Set the application badge number in ios 9

问题描述

我用过

[UIApplication sharedApplication].applicationIconBadgeNumber = 5;

用于设置应用程序徽章编号。它不能单独在ios 9中使用。

for setting application badge number. It's not working in ios 9 alone.

任何人都可以建议为什么？

Can anyone suggest why?

我试过了，

[[UIApplication sharedApplication] setApplicationIconBadgeNumber:5];

推荐答案

您需要注册这样的UIUserNotificationSettings

Hi You need to register UIUserNotificationSettings like this

UIUserNotificationSettings* notificationSettings = [UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeAlert | UIUserNotificationTypeBadge | UIUserNotificationTypeSound categories:nil];

[[UIApplication sharedApplication] registerUserNotificationSettings:notificationSettings];

[UIApplication sharedApplication].applicationIconBadgeNumber = 1;
