检查是否在 IOS 8 中启用了本地通知

问题描述

我已经在互联网上查看了如何使用 IOS 8 创建本地通知.我找到了很多文章，但没有解释如何确定用户是否已打开或关闭警报".有人可以帮我吗！！！我更喜欢使用 Objective C 而不是 Swift.

I've looked all over the internet for how to create local notifications with IOS 8. I found many articles, but none explained how to determine if the user has set "alerts" on or off. Could someone please help me!!! I would prefer to use Objective C over Swift.

推荐答案

您可以使用 UIApplication 的 currentUserNotificationSettings

if ([[UIApplication sharedApplication] respondsToSelector:@selector(currentUserNotificationSettings)]){ // Check it's iOS 8 and above
    UIUserNotificationSettings *grantedSettings = [[UIApplication sharedApplication] currentUserNotificationSettings];

    if (grantedSettings.types == UIUserNotificationTypeNone) {
        NSLog(@"No permiossion granted");
    }
    else if (grantedSettings.types & UIUserNotificationTypeSound & UIUserNotificationTypeAlert ){
        NSLog(@"Sound and alert permissions ");
    }
    else if (grantedSettings.types  & UIUserNotificationTypeAlert){
        NSLog(@"Alert Permission Granted");
    }
}
