解决iOS 10 之后调用拨号，系统弹窗延迟

#define IOS_VERSION_10 (NSFoundationVersionNumber > NSFoundationVersionNumber_iOS_9_x_Max)?(YES):(NO)

+ (void)callupWithPhoneNum:(NSString *)phoneNum andController:(UIViewController *)controller {
    //拨打电话
    NSURL *phoneURL = [NSURL URLWithString:[NSString stringWithFormat:@"telprompt://%@",phoneNum]];
    if (IOS_VERSION_10) {
        /// 大于等于10.0系统使用此openURL方法
        [[UIApplication sharedApplication] openURL:phoneURL options:@{} completionHandler:nil];
    }else {
        [[UIApplication sharedApplication] openURL:phoneURL];
    }
    
}
