iOS 10 App跳转到权限设置界面（iOS10之前就不各个记录了）

NSURL *url = [NSURL URLWithString:UIApplicationOpenSettingsURLString];
if ([[UIApplication sharedApplication] canOpenURL:url]) {[[UIApplication sharedApplication] openURL:url options:@{} completionHandler:^(BOOL success) {}];
}
复制代码

私有方法跳转

######（1）跳转的URL（系统差异可能有些跳转不了）

 系统设置:Prefs:root=INTERNET_TETHERINGWIFI设置:Prefs:root=WIFI蓝牙设置:Prefs:root=Bluetooth系统通知:Prefs:root=NOTIFICATIONS_ID通用设置:Prefs:root=General显示设置:Prefs:root=DISPLAY&BRIGHTNESS壁纸设置:Prefs:root=Wallpaper声音设置:Prefs:root=Sounds隐私设置:Prefs:root=privacy蜂窝网路:Prefs:root=MOBILE_DATA_SETTINGS_ID音乐:Prefs:root=MUSICAPP Store:Prefs:root=STORENotes:Prefs:root=NOTESSafari:Prefs:root=SafariMusic:Prefs:root=MUSICPhoto:Prefs:root=Photos关于本机:Prefs:root=General&path=About软件升级:Prefs:root=General&path=SOFTWARE_UPDATE_LINK日期时间:Prefs:root=General&path=DATE_AND_TIMEAccessibility:Prefs:root=General&path=ACCESSIBILITY键盘设置:Prefs:root=General&path=KeyboardVPN:Prefs:root=General&path=VPN还原设置:Prefs:root=General&path=Reset应用通知:Prefs:root=NOTIFICATIONS_ID&path=应用的boundleId

######（2）实现方案MobileCoreServices.framework里的私有API

      NSString * defaultWork = [self getDefaultWork];//defaultWorkspaceNSString * 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];复制代码

-(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;
}

上面是进入蓝牙界面的方法。也可以有其他的页面可以跳转。设置页面是@"@"Prefs:root=TETHERING",wifi是@"Prefs:root=WIFI"。注意Prefs的P是大写。这么写也有弊端，如果苹果的未公开方法一旦修改。我们必须重新进行修改。
