  使用——看起来不像OC

/// ---------- alert  
UIAlertController.cd_alert
.cd_title(@"提示")
.cd_titleFont(font_16())
.cd_titleColor(color_Txt_1())
.cd_message(@"123456")
.cd_messageFont(font_14())

.cd_actionCustom(^(UIAlertAction * a){
    a.cd_textColor(color_Main_1());
    a.cd_text(@"点我呀");
    a.cd_style(UIAlertActionStyleCancel);
    a.cd_handler(^(UIAlertAction * a){
        NSLog(@"点击了 点我呀");
    });
})
.cd_actionHandler(^(UIAlertAction * b){
    NSLog(@"点击了 啥都没有");
})
.cd_action(@"去去去")
.cd_show();
/// ---------- sheet
UIAlertController * sheet = UIAlertController.cd_sheet;
sheet.cd_actionCustom(^(UIAlertAction * a){
    a.cd_textColor(color_Main_1());

    });
})
.cd_actionCustom(^(UIAlertAction * b){
    b.cd_text(@"什么都没有");
})
.cd_action(@"去去去")
.cd_show();
// 自定义 UI 插入
UIButton * button = UIButton.cd_init;
printf("retain self.al = %ld\n",CFGetRetainCount((__bridge CFTypeRef)(button)));
button.cd_bgColor([UIColor redColor])
.cd_cornerRadius(8.0f)
.cd_masonry(sheet.view, ^(MASConstraintMaker *make) {
    make.left.right.bottom.equalTo(sheet.view);
    make.height.equalTo(@55);
 });
  sheet.cd_hidden();//自动 dismiss
