iOS app跳转到系统设置

//无权限
        NSString * urlString = @"App-Prefs:root=Privacy";
        
        if ([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:urlString]]) {
            
            if ([[UIDevice currentDevice].systemVersion doubleValue] >= 10.0) {
                [[UIApplication sharedApplication] openURL:[NSURL URLWithString:urlString] options:@{} completionHandler:nil];
            } else {
                [[UIApplication sharedApplication] openURL:[NSURL URLWithString:urlString]];
            }
        }
