通过 openURL 方法跳转至设置 - iOS

iOS 10 以下系统版本可以通过 openURL 的方式跳转至指定的设置界面,code 如下:

NSURL *url = [NSURL URLWithString:@"prefs:root=LOCATION_SERVICES"];// iOS 10 弃用
if( [[UIApplication sharedApplication] canOpenURL:url]) {
    [[UIApplication sharedApplication] openURL:url];
}

跳转至具体各个功能模块对应的参数如下:

    About — prefs:root=General&path=About
 
    Accessibility — prefs:root=General&path=ACCESSIBILITY
 
    Airplane Mode On — prefs:root=AIRPLANE_MODE

iOS 10 以上系统版本运行异常如下:

-canOpenURL: failed for URL: "prefs:root=LOCATION_SERVICES" - error: "The operation couldn’t be completed. (OSStatus error -10814.)"

解决办法,改成跳转至系统设置页面,完后再进行对应的配置选项进行设置,code 如下:

NSURL *url = [[NSURL alloc] initWithString:UIApplicationOpenSettingsURLString];// 跳转至系统设置
//NSURL *url = [NSURL URLWithString:@"prefs:root=LOCATION_SERVICES"];// iOS 10 弃用
if( [[UIApplication sharedApplication] canOpenURL:url]) {
    [[UIApplication sharedApplication] openURL:url];
}

以下是以位置访问权限为例写的例子,仅以此参考.
