请求使用授权显示没有提示

问题描述

我有

NSLocationWhenInUseUsageDescription

和

NSLocationAlwaysUsageDescription

在我的Info.plist中定义。

defined in my Info.plist.

在我的代码中我做了

    if ([_locationManager respondsToSelector:@selector(requestWhenInUseAuthorization)]) {
        [_locationManager requestWhenInUseAuthorization];
    }

    [_locationManager startUpdatingLocation];

我不会在iOS8上收到提示。

And I don't get prompted on iOS8.

我在我的模拟器中做了一个干净的重新安装。在没有3 if块的iOS7上，我会收到提示。

I did a clean reinstall in my simulator. On iOS7 without the 3 if block I get prompted.

在startUpdatingLocation之后我检查 [CLLocationManager authorizationStatus] 这是 0- kCLAuthorizationStatusNotDetermined

Right after startUpdatingLocation I check [CLLocationManager authorizationStatus] which is 0- kCLAuthorizationStatusNotDetermined

如何提示iOS8用户？

How do I prompt iOS8 users?

推荐答案

4 ios 8：需要在info.plist中配置它，

4 ios 8: Need configure it in info.plist,

键名为NSLocationAlwaysUsageDescription值为

key name as "NSLocationAlwaysUsageDescription" value as ""

密钥名称为NSLocationWhenInUseUsageDescription值为

key name as "NSLocationWhenInUseUsageDescription" value as ""

当您致电：

[_locationManager requestWhenInUseAuthorization];

将自动提示。

测试使用模拟器，您可以单击重置内容和设置...并再次提示。

Testing with simulator, you can click "Reset content and settings..." and prompt again.
