系统权限问题
iOS 10加强的隐私数据保护，需要使用系统权限必须弹框提示用户，同意才能使用，而且要在plist中添加相应的key。
10之前只需要获取位置时配置，现在更严格了，比如需要调用相册访问权限，也需要在Info.plist中配置privacy。好在这些key的名字在Xcode 8中已经有了自动补全。添加一个属性，输入Privacy后就会出现自动提示:
后面填的string会在弹出用户允许时展示在描述里。如果描述空着提交AppStore时会拒绝。
用户在点击允许后一切正常，但是点击不允许之后就需要对权限的状态进行判断，并作出相应的处理。
或者你直接粘贴需要的权限:
<key>NSPhotoLibraryUsageDescription</key>
<string>我们需要您的相册权限</string>
<key>NSMicrophoneUsageDescription</key>
<string>我们需要您的麦克风权限</string>
<key>NSCameraUsageDescription</key>
<string>我们需要您的相机权限</string>

如果你拒绝了某个权限,以麦克风为例,下次用到此功能需要给予用户提示:
//提示用户进行麦克风使用授权
- (void)showSetAlertView {
UIAlertController *alertVC = [UIAlertController alertControllerWithTitle:@"麦克风权限未开启" message:@"麦克风权限未开启，请进入系统【设置】>【隐私】>【麦克风】中打开开关,开启麦克风功能" preferredStyle:UIAlertControllerStyleAlert];
UIAlertAction *cancelAction = [UIAlertAction actionWithTitle:@"取消" style:UIAlertActionStyleCancel handler:^(UIAlertAction * _Nonnull action) {
}];
UIAlertAction *setAction = [UIAlertAction actionWithTitle:@"去设置" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {
//跳入当前App设置界面
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:UIApplicationOpenSettingsURLString]];
}];
[alertVC addAction:cancelAction];
[alertVC addAction:setAction];
[self presentViewController:alertVC animated:YES completion:nil];
}
谢谢!!!
