ios APP跳转到系统应用设置页

1、获取用户通知中心对程序消息通知的设置，是否开启消息通知

if ([[UIDevice currentDevice].systemVersion floatValue]>=8.0f) { 
       UIUserNotificationSettings *setting = [[UIApplication sharedApplication] currentUserNotificationSettings]; 
if (UIUserNotificationTypeNone == setting.types) { 
      NSLog(@"推送关闭");
 }else{
      NSLog(@"推送打开"); }
 }else{
     UIRemoteNotificationType type = [[UIApplication sharedApplication] enabledRemoteNotificationTypes]; if(UIRemoteNotificationTypeNone == type){ 
    NSLog(@"推送关闭");
 }else{ 
     NSLog(@"推送打开");
 } }

2、去设置
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:UIApplicationOpenSettingsURLString]];

补充资料： 在iOS应用程序中打开设备设置界面及其中某指定的选项界面
[[UIApplicationsharedApplication] openURL:[NSURL URLWithString:@”prefs:root=General”]]; [[UIApplicationsharedApplication] openURL:[NSURL URLWithString:@”prefs:root=General&path=Restrictions”]];

一些其他可用的参数:
List of currently known URLs in the Settings app:
prefs:root=General&path=About //关于 prefs:root=General&path=ACCESSIBILITY//重力感应
prefs:root=AIRPLANE_MODE//飞行模式 prefs:root=General&path=AUTOLOCK//自动锁定 prefs:root=General&path=USAGE/CELLULAR_USAGE//用量 prefs:root=Brightness//亮度调节 prefs:root=General&path=Bluetooth//蓝牙 prefs:root=General&path=DATE_AND_TIME//时间和日期 prefs:root=FACETIME// prefs:root=General//通用 prefs:root=General&path=Keyboard//键盘 prefs:root=CASTLE// prefs:root=CASTLE&path=STORAGE_AND_BACKUP// prefs:root=General&path=INTERNATIONAL// prefs:root=LOCATION_SERVICES//定位 prefs:root=ACCOUNT_SETTINGS// prefs:root=MUSIC//音乐 prefs:root=MUSIC&path=EQ// prefs:root=MUSIC&path=VolumeLimit// prefs:root=General&path=Network//网络 prefs:root=NIKE_PLUS_IPOD// prefs:root=NOTES// prefs:root=NOTIFICATIONS_ID// prefs:root=Phone// prefs:root=Photos//相册 prefs:root=General&path=ManagedConfigurationList// prefs:root=General&path=Reset// prefs:root=Sounds&path=Ringtone// prefs:root=Safari// prefs:root=General&path=Assistant// prefs:root=Sounds//声音 prefs:root=General&path=SOFTWARE_UPDATE_LINK// prefs:root=STORE// prefs:root=TWITTER// prefs:root=General&path=USAGE// prefs:root=VIDEO//视频 prefs:root=General&path=Network/VPN// prefs:root=Wallpaper//壁纸 prefs:root=WIFI// prefs:root=INTERNET_TETHERING//
