Question

我正在使用此插件http://plugins.krajee.com/file-input/plugin-events 当您按DELETE BUTTOM时，通过删除所有上载或预加载的文件来执行此事件我需要一个类似的事件，但是当我删除上传或预载了DELETE ICON的单个文件时我该怎么办？

class Spaceship {

    var isUFO = false  
    var weapon:String 

     init(weapon:String) {      
         self.weapon = weapon
     }

    func printSomething() {
     print("Test")
    }
}

class UFO: Spaceship {
}


var a = Spaceship(weapon:"Laser")
a.printSomething() //OUTPUT: Test

var b = UFO(weapon:"")  
          //This runs, but I don't want to have to fill in parameters
b.printSomething()    //OUTPUT: Test

var c = UFO()       //Ultimately this is what I want to do
c.printSomething()  
       //OUTPUT: missing argument for parameter 'weapon' in call var c =    UFO()

已清除文件输入中的文件删除
