有没有一种方法可以使用简介,但只删除行的格式化程序?

$0.formatter = nil 就在这个下面 $0.placeholder = "Enter Asset Tag #"

你的第一个问题 section 在里面 EurekaForm tag 作为参数,为了获得正确的节,您需要更改此节的节初始化

        +++ Section("iOS Version"){ //"iOS Version" is actually the header text"
            $0.tag = "test"  //this is the tag
        }

.onChange { row in

              self.form.sectionBy(tag: "iOS Version")?.hidden = true
        }

通过这个

 .onChange { row in
                if let section = self.form.sectionBy(tag: "test")
                {
                    section.hidden = true 
                    section.evaluateHidden()   //you are missing calling this method
                }
        }

在这之后,在您的页面上写下任何数字后,名为“iOS版本”的标题就会隐藏 IntRow

form  +++ Section("Device Search")
            
            <<< IntRow()
                {
                    $0.title = "Asset Tag"
                    $0.placeholder = "Enter Asset Tag #"
                    $0.formatter = nil
                }
                
                .onChange { row in
                    if let section = self.form.sectionBy(tag: "test")
                    {
                        section.hidden = true
                        section.evaluateHidden()
                    }
            }
            
            +++ Section("iOS Version"){
                $0.tag = "test"
        }
        
        for version in countArray
        {
            form.last! <<< CheckRow()
                {
                    $0.title = version
                    $0.tag = $0.title
            }
        }
