本文介绍了此类与@IBInspectable不符合键值编码的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧! 问题描述 29岁程序员,3月因学历无情被辞! 我在自定义视图上创建了一个@ IBDesignable ,以便从IB设置属性。但是我觉得这个课程不符合关键值编码,尽管我班上有这个属性。I created a @IBDesignable on a custom view to set a property from IB. But i get this class is not key value coding-compliant despite i have that attribute in my class.@IBDesignable class ExclusiveSelectorView: UIView { @IBInspectable var cellWidth: CGFloat?}无法设置(cellWidth)用户定义的检查属性(Test.ExclusiveSelectorView) :[setValue:forUndefinedKey:]:此类不是密钥cellWidth的密钥值编码兼容。Failed to set (cellWidth) user defined inspected property on (Test.ExclusiveSelectorView): [ setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key cellWidth.这是我的班级推荐答案您不能将基元定义为 @IBInspectable 的可为空。You cannot define primitives as nullable for @IBInspectables.当您尝试时要这样做,并设置其中一个属性的值,您将在IBDesignable时间收到以下警告:When you attempt to do so, and set the value for one of these properties, you'll get the following warning at IBDesignable time: @IBDesignable class TestDesignable IB Designables:忽略用户定义的运行时attri在TestDesignable实例上为关键路径testInt提供静音。尝试设置其值时遇到异常:[setValue:forUndefinedKey:]:此类不是密钥testInt的密钥值编码兼容。 @IBDesignable class TestDesignable IB Designables: Ignoring user defined runtime attribute for key path "testInt" on instance of "TestDesignable". Hit an exception when attempting to set its value: [ setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key testInt.在运行时,您将收到以下错误:And at runtime, you'll get the following error: 无法设置(testInt)用户定义的检查属性( TestDesignable):[setValue:forUndefinedKey:]:此类不是密钥testInt的密钥值编码兼容。 Failed to set (testInt) user defined inspected property on (TestDesignable): [ setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key testInt.修复它,将其从可选更改为非可选,并将其设为零默认值。To fix it, change it from an optional to non-optional, and give it some zero default value.无效:@IBDesignable class TestDesignable: UIView { @IBInspectable var testInt: Int? = nil // crash @IBInspectable var testFloat: CGFloat? = nil // crash @IBInspectable var testPoint: CGPoint? = nil // crash @IBInspectable var testColor: UIColor? = nil}有效期:@IBDesignable class TestDesignable: UIView { @IBInspectable var testInt: Int = 0 @IBInspectable var testFloat: CGFloat = 0 @IBInspectable var testPoint: CGPoint = .zero @IBInspectable var testColor: UIColor? = nil} 这篇关于此类与@IBInspectable不符合键值编码的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持! 阿里云证书,YYDS! 05-23 15:08
