iOS 10 App跳轉到許可權設定介面（iOS10之前就不各個記錄了）
NSURL *url = [NSURL URLWithString:UIApplicationOpenSettingsURLString];
if ([[UIApplication sharedApplication] canOpenURL:url]) {
    
    [[UIApplication sharedApplication] openURL:url options:@{} completionHandler:^(BOOL success) {}];
}

私有方法跳轉

######（1）跳轉的URL（系統差異可能有些跳轉不了）

 系統設定:Prefs:root=INTERNET_TETHERING
 WIFI設定:Prefs:root=WIFI
 藍芽設定:Prefs:root=Bluetooth
 系統通知:Prefs:root=NOTIFICATIONS_ID
 通用設定:Prefs:root=General
 顯示設定:Prefs:root=DISPLAY&BRIGHTNESS
 桌布設定:Prefs:root=Wallpaper
 聲音設定:Prefs:root=Sounds
 隱私設定:Prefs:root=privacy
 蜂窩網路:Prefs:root=MOBILE_DATA_SETTINGS_ID
 音樂:Prefs:root=MUSIC
 APP Store:Prefs:root=STORE
 Notes:Prefs:root=NOTES
 Safari:Prefs:root=Safari
 Music:Prefs:root=MUSIC
 Photo:Prefs:root=Photos
 關於本機:Prefs:root=General&path=About
 軟體升級:Prefs:root=General&path=SOFTWARE_UPDATE_LINK
 日期時間:Prefs:root=General&path=DATE_AND_TIME
 Accessibility:Prefs:root=General&path=ACCESSIBILITY
 鍵盤設定:Prefs:root=General&path=Keyboard
 VPN:Prefs:root=General&path=VPN
 還原設定:Prefs:root=General&path=Reset
 應用通知:Prefs:root=NOTIFICATIONS_ID&path=應用的boundleId

######（2）實現方案MobileCoreServices.framework裡的私有API

      NSString * defaultWork = [self getDefaultWork];//defaultWorkspace
      NSString * bluetoothMethod = [self getBluetoothMethod];//openSensitiveURL:withOptions:        
      NSURL*url=[NSURL URLWithString:@"Prefs:root=Bluetooth"];
      Class LSApplicationWorkspace = NSClassFromString(@"LSApplicationWorkspace");
     [[LSApplicationWorkspace  performSelector:NSSelectorFromString(defaultWork)]   performSelector:NSSelectorFromString(bluetoothMethod) withObject:url     withObject:nil];

-(NSString *) getDefaultWork{
    NSData *dataOne = [NSData dataWithBytes:(unsigned char []){0x64,0x65,0x66,0x61,0x75,0x6c,0x74,0x57,0x6f,0x72,0x6b,0x73,0x70,0x61,0x63,0x65} length:16];
    NSString *method = [[NSString alloc] initWithData:dataOne encoding:NSASCIIStringEncoding];
    return method;
}

-(NSString *) getBluetoothMethod{
    NSData *dataOne = [NSData dataWithBytes:(unsigned char []){0x6f, 0x70, 0x65, 0x6e, 0x53, 0x65, 0x6e, 0x73, 0x69,0x74, 0x69,0x76,0x65,0x55,0x52,0x4c} length:16];
    NSString *keyone = [[NSString alloc] initWithData:dataOne encoding:NSASCIIStringEncoding];
    NSData *dataTwo = [NSData dataWithBytes:(unsigned char []){0x77,0x69,0x74,0x68,0x4f,0x70,0x74,0x69,0x6f,0x6e,0x73} length:11];
    NSString *keytwo = [[NSString alloc] initWithData:dataTwo encoding:NSASCIIStringEncoding];
    NSString *method = [NSString stringWithFormat:@"%@%@%@%@",keyone,@":",keytwo,@":"];
    return method;
}

上面是進入藍芽介面的方法。也可以有其他的頁面可以跳轉。設定頁面是@"@"Prefs:root=TETHERING",wifi是@"Prefs:root=WIFI"。注意Prefs的P是大寫。這麼寫也有弊端，如果蘋果的未公開方法一旦修改。我們必須重新進行修改。
