iOS8之后用一下方法跳轉(zhuǎn)到設(shè)置界面
//手機(jī)系統(tǒng)版本號(hào)
#define SYSTEMVERSION [[[UIDevice currentDevice]systemVersion]floatValue]
//跳轉(zhuǎn)到設(shè)置界面，讓用戶開啟權(quán)限
NSURL *url;
if(SYSTEMVERSION >= 8.0)
{
//iOS8 以后
url = [NSURL URLWithString:UIApplicationOpenSettingsURLString]; if ([[UIApplication sharedApplication] canOpenURL:url])
[[UIApplication sharedApplication] openURL:url];
}
補(bǔ)充資料：
在iOS應(yīng)用程序中打開設(shè)備設(shè)置界面及其中某指定的選項(xiàng)界面
NSURL *url = [NSURL URLWithString:@“prefs:xxx"];
if ([[UIApplication sharedApplication] canOpenURL:url])
{
[[UIApplication sharedApplication] openURL:url];
}
一些其他可用的參數(shù):
隱私下常用字段
@"prefs:root=Privacy&path=CAMERA"
,
//設(shè)置相機(jī)使用權(quán)限
@"prefs:root=Privacy&path=PHOTOS"
//設(shè)置照片使用權(quán)限
打開一級(jí)界面可將上面的字符串修改為以下對(duì)應(yīng)的字段:
@"prefs:root=WIFI"
,//打開WiFi
@"prefs:root=Bluetooth"
,//打開藍(lán)牙設(shè)置頁
@"prefs:root=NOTIFICATIONS_ID"
,//通知設(shè)置
@"prefs:root=General"
,//通用
@"prefs:root=DISPLAY&BRIGHTNESS",//顯示與亮度
@"prefs:root=Wallpaper",//墻紙
@"prefs:root=Sounds",//聲音
@"prefs:root=Privacy",//隱私
@"prefs:root=STORE",//存儲(chǔ)
@"prefs:root=NOTES",//備忘錄
@"prefs:root=SAFARI",//Safari
@"prefs:root=MUSIC",//音樂
@"prefs:root=Photos",//照片與相機(jī)
@"prefs:root=CASTLE"http://iCloud
@"prefs:root=FACETIME",//FaceTime
@"prefs:root=LOCATION_SERVICES",//定位服務(wù)
@"prefs:root=Phone",//電話
@"prefs:root=AIRPLANE_MODE"http://飛行模式
@"prefs:root=General&path=Network"http://網(wǎng)絡(luò)
@"prefs:root=VIDEO"http://視頻
prefs:root=CASTLE&path=STORAGE_AND_BACKUP//
prefs:root=General&path=INTERNATIONAL//
prefs:root=ACCOUNT_SETTINGS//
prefs:root=MUSIC&path=EQ//
prefs:root=MUSIC&path=VolumeLimit//
prefs:root=NIKE_PLUS_IPOD//
prefs:root=General&path=ManagedConfigurationList//
prefs:root=General&path=Reset//
prefs:root=Sounds&path=Ringtone//
prefs:root=General&path=Assistant//
prefs:root=General&path=SOFTWARE_UPDATE_LINK//
prefs:root=TWITTER// prefs:root=General&path=USAGE//
prefs:root=General&path=Network/VPN//
prefs:root=INTERNET_TETHERING//
通用下常用字段
@"prefs:root=General&path=About",//關(guān)于本機(jī)
@"prefs:root=General&path=SOFTWARE_UPDATE_LINK",//軟件更新
@"prefs:root=General&path=DATE_AND_TIME",//日期和時(shí)間
@"prefs:root=General&path=ACCESSIBILITY",//輔助功能
@"prefs:root=General&path=Keyboard",//鍵盤
@"prefs:root=General&path=VPN",//VPN設(shè)置
@"prefs:root=General&path=AUTOLOCK",//自動(dòng)鎖屏
@"prefs:root=General&path=INTERNATIONAL",//語言與地區(qū)
@"prefs:root=General&path=ManagedConfigurationList",//描述文件
prefs:root=General&path=ACCESSIBILITY//重力感應(yīng)
