iOS 各种权限判断及设置跳转

iOS8之后用一下方法跳转到设置界面

//手机系统版本号
#define SYSTEMVERSION [[[UIDevice currentDevice]systemVersion]floatValue]
//跳转到设置界面，让用户开启权限        
NSURL *url;        
if(SYSTEMVERSION >= 8.0)      
 {            
//iOS8 以后           
url = [NSURL URLWithString:UIApplicationOpenSettingsURLString];            if ([[UIApplication sharedApplication] canOpenURL:url])           
[[UIApplication sharedApplication] openURL:url];      
 }

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

NSURL *url = [NSURL URLWithString:@“prefs:xxx"];
 if ([[UIApplication sharedApplication] canOpenURL:url])
 {     
    [[UIApplication sharedApplication] openURL:url]; 
 }

一些其他可用的参数:
隐私下常用字段

@"prefs:root=Privacy&path=CAMERA"
,
//设置相机使用权限
@"prefs:root=Privacy&path=PHOTOS"
//设置照片使用权限

打开一级界面可将上面的字符串修改为以下对应的字段:

@"prefs:root=WIFI"
,//打开WiFi

@"prefs:root=Bluetooth"
,//打开蓝牙设置页

@"prefs:root=NOTIFICATIONS_ID"
,//通知设置

@"prefs:root=General"
,//通用
@"prefs:root=DISPLAY&BRIGHTNESS",//显示与亮度
@"prefs:root=Wallpaper",//墙纸
@"prefs:root=Sounds",//声音
@"prefs:root=Privacy",//隐私
@"prefs:root=STORE",//存储
@"prefs:root=NOTES",//备忘录
@"prefs:root=SAFARI",//Safari
@"prefs:root=MUSIC",//音乐
@"prefs:root=Photos",//照片与相机
@"prefs:root=CASTLE"//iCloud
@"prefs:root=FACETIME",//FaceTime
@"prefs:root=LOCATION_SERVICES",//定位服务
@"prefs:root=Phone",//电话
@"prefs:root=AIRPLANE_MODE"//飞行模式 
@"prefs:root=General&path=Network"//网络
@"prefs:root=VIDEO"//视频

 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",//关于本机 
@"prefs:root=General&path=SOFTWARE_UPDATE_LINK",//软件更新 
@"prefs:root=General&path=DATE_AND_TIME",//日期和时间
@"prefs:root=General&path=ACCESSIBILITY",//辅助功能
@"prefs:root=General&path=Keyboard",//键盘 
@"prefs:root=General&path=VPN",//VPN设置 
@"prefs:root=General&path=AUTOLOCK",//自动锁屏
@"prefs:root=General&path=INTERNATIONAL",//语言与地区 
@"prefs:root=General&path=ManagedConfigurationList",//描述文件
prefs:root=General&path=ACCESSIBILITY//重力感应  
prefs:root=General&path=USAGE/CELLULAR_USAGE//用量
