如何连续变更多个UITextField中的多个文本值？

Question

我正在寻找一种方法来找到一种更有效的方法来将多个UITextFields（在这种情况下，donorView1，donorView2等）我的报价变化后，只需点击一个UIButton。点击Randomize按钮会产生一个引号数组，但是，使用这个引号数组，我只能得到每个字段一个引号，但是我需要在每个方框中引用不同的引号（即donorView1会有字母DQ，A，DP，DR而donorView2可能有A，C，B，DP）。我对这段代码很陌生 - 因为这是我第一次编写一个iOS应用程序 - 所以如果可能的话，请尝试用简单的语言来解释！每个文本字段至少需要6个随机字母。

@IBOutlet weak var patientView: UITextField! 

@IBAction func patientFunction(sender: UIButton!) { 
} 
@IBOutlet weak var donorView1: UITextField! 

@IBOutlet weak var donorView2: UITextField! 

@IBOutlet weak var donorView3: UITextField! 

@IBOutlet weak var donorView4: UITextField! 

@IBOutlet weak var donorView5: UITextField! 

@IBOutlet weak var donorView6: UITextField! 

@IBOutlet weak var donorView7: UITextField! 

@IBOutlet weak var donorView8: UITextField! 

@IBOutlet weak var Randomize: UIButton! 

@IBAction func Randomize(sender: UIButton!) { 

    let quoteArray1 = [" -A,", " -B,", " -C,", " -DR,", " -DQ, ", " -DP,"] 
    self.patientView.text = quoteArray1 [Int(arc4random_uniform(UInt32(quoteArray1.count)))] + quoteArray1[Int(arc4random_uniform(UInt32(quoteArray1.count)))] + quoteArray1[Int(arc4random_uniform(UInt32(quoteArray1.count)))] 
    self.donorView1.text = quoteArray1[Int(arc4random_uniform(UInt32(quoteArray1.count)))] + quoteArray1[Int(arc4random_uniform(UInt32(quoteArray1.count)))] + quoteArray1[Int(arc4random_uniform(UInt32(quoteArray1.count)))] 
    self.donorView1.text = quoteArray1[Int(arc4random_uniform(UInt32(quoteArray1.count)))] + quoteArray1[Int(arc4random_uniform(UInt32(quoteArray1.count)))] + quoteArray1[Int(arc4random_uniform(UInt32(quoteArray1.count)))] 
    self.donorView2.text = quoteArray1[Int(arc4random_uniform(UInt32(quoteArray1.count)))] + quoteArray1[Int(arc4random_uniform(UInt32(quoteArray1.count)))] + quoteArray1[Int(arc4random_uniform(UInt32(quoteArray1.count)))] 
    self.donorView3.text = quoteArray1[Int(arc4random_uniform(UInt32(quoteArray1.count)))] + quoteArray1[Int(arc4random_uniform(UInt32(quoteArray1.count)))] + quoteArray1[Int(arc4random_uniform(UInt32(quoteArray1.count)))] 
    self.donorView4.text = quoteArray1[Int(arc4random_uniform(UInt32(quoteArray1.count)))] + quoteArray1[Int(arc4random_uniform(UInt32(quoteArray1.count)))] + quoteArray1[Int(arc4random_uniform(UInt32(quoteArray1.count)))] 
    self.donorView5.text = quoteArray1[Int(arc4random_uniform(UInt32(quoteArray1.count)))] + quoteArray1[Int(arc4random_uniform(UInt32(quoteArray1.count)))] + quoteArray1[Int(arc4random_uniform(UInt32(quoteArray1.count)))] 
    self.donorView6.text = quoteArray1[Int(arc4random_uniform(UInt32(quoteArray1.count)))] + quoteArray1[Int(arc4random_uniform(UInt32(quoteArray1.count)))] + quoteArray1[Int(arc4random_uniform(UInt32(quoteArray1.count)))] 
    self.donorView7.text = quoteArray1[Int(arc4random_uniform(UInt32(quoteArray1.count)))] + quoteArray1[Int(arc4random_uniform(UInt32(quoteArray1.count)))] + quoteArray1[Int(arc4random_uniform(UInt32(quoteArray1.count)))] 
    self.donorView8.text = quoteArray1[Int(arc4random_uniform(UInt32(quoteArray1.count)))] + quoteArray1[Int(arc4random_uniform(UInt32(quoteArray1.count)))] + quoteArray1[Int(arc4random_uniform(UInt32(quoteArray1.count)))] 
} 

    override func viewDidLoad() { 

    super.viewDidLoad() 
    // Do any additional setup after loading the view, typically from a nib. 
} 

override func didReceiveMemoryWarning() { 
    super.didReceiveMemoryWarning() 
    // Dispose of any resources that can be recreated. 
}

let textFields: [UITextField] = [self.patientView, self.donorView1, 2, 3, etc.] 
let quoteArray1 = [" -A,", " -B,", " -C,", " -DR,", " -DQ, ", " -DP,"] 
let randomRange = UInt32(quoteArray1.count) 
for textField in textFields { 
    textField.text = quoteArray1 [Int(arc4random_uniform(randomRange))] + 
       quoteArray1[Int(arc4random_uniform(randomRange))] + 
       quoteArray1[Int(arc4random_uniform(randomRange))] 
} 

只是风格上的说明，将节省您在长期，保持出口和动作在自己的部分，而沟店...... :)

之间的间距更新：

如果需要显示每个在各种序列的阵列元件上的所有文本框，你应该随机洗牌的阵列和设置与每个数组元素的级联的文本。在设置每个标签之前，先将数组随意排列。
