通过 openURL 方法跳转至设置 - iOS

本文主要是介绍通过 openURL 方法跳转至设置 - iOS，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

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=AboutAccessibility — prefs:root=General&path=ACCESSIBILITYAirplane Mode On — prefs:root=AIRPLANE_MODEAuto-Lock — prefs:root=General&path=AUTOLOCKBrightness — prefs:root=BrightnessBluetooth — prefs:root=General&path=BluetoothDate & Time — prefs:root=General&path=DATE_AND_TIMEFaceTime — prefs:root=FACETIMEGeneral — prefs:root=GeneralKeyboard — prefs:root=General&path=KeyboardiCloud — prefs:root=CASTLEiCloud Storage & Backup — prefs:root=CASTLE&path=STORAGE_AND_BACKUPInternational — prefs:root=General&path=INTERNATIONALLocation Services — prefs:root=LOCATION_SERVICESMusic — prefs:root=MUSICMusic Equalizer — prefs:root=MUSIC&path=EQMusic Volume Limit — prefs:root=MUSIC&path=VolumeLimitNetwork — prefs:root=General&path=NetworkNike + iPod — prefs:root=NIKE_PLUS_IPODNotes — prefs:root=NOTESNotification — prefs:root=NOTIFICATIONS_IDPhone — prefs:root=PhonePhotos — prefs:root=PhotosProfile — prefs:root=General&path=ManagedConfigurationListReset — prefs:root=General&path=ResetSafari — prefs:root=SafariSiri — prefs:root=General&path=AssistantSounds — prefs:root=SoundsSoftware Update — prefs:root=General&path=SOFTWARE_UPDATE_LINKStore — prefs:root=STORETwitter — prefs:root=TWITTERUsage — prefs:root=General&path=USAGEVPN — prefs:root=General&path=Network/VPNWallpaper — prefs:root=WallpaperWi-Fi — prefs:root=WIFI

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.
