Use of unresolved IDentifIEr ‘Static’
这是我在以前的版本xcode 7.3.1 swift 2中创建和使用的类.
import UIKitenum FontSIZE:Int{ case sizesmall = 1 case sizesbig = 2 case sizemedium = 3}class sizeFont: NSObject { private static var __once: () = { Static.instance = sizeFont() }() class func getSize(_ enumFont : FontSIZE) -> CGfloat { var siz = 17 switch(enumFont){ case .sizesbig: if((UserDefaults.standard.value(forKey: "Fontsize") as AnyObject).int32Value == 0){// kecil if(isphone()){ siz = 22//17 }else{ siz = 22//24 } }else if((UserDefaults.standard.value(forKey: "Fontsize") as AnyObject).int32Value == 1){// besar if(isphone()){ siz = 30//19 }else{ siz = 30//28 } }else{ if(isphone()){ siz = 22//17 }else{ siz = 22//22 } } break case .sizesmall: if((UserDefaults.standard.value(forKey: "Fontsize") as AnyObject).int32Value == 0){// kecil if(isphone()){ siz = 17//15//12 }else{ siz = 24//22//19 } }else if((UserDefaults.standard.value(forKey: "Fontsize") as AnyObject).int32Value == 1){// besar if(isphone()){ siz = 19//17//15 }else{ siz = 28//26//24 } }else{ if(isphone()){ siz = 17//15//12 }else{ siz = 24//22//19 } } break case .sizemedium: if((UserDefaults.standard.value(forKey: "Fontsize") as AnyObject).int32Value == 0){// kecil if(isphone()){ siz = 15 }else{ siz = 22 } }else if((UserDefaults.standard.value(forKey: "Fontsize") as AnyObject).int32Value == 1){// besar if(isphone()){ siz = 17 }else{ siz = 26 } }else{ if(isphone()){ siz = 15 }else{ siz = 22 } } break } return CGfloat(siz) } func getnaMetag(){ } class func isphone() ->Bool { if(UIDevice.current.userInterfaceIdiom == UIUserInterfaceIdiom.phone){ return true }else{ return false } } // example singleton swift class var sharedInstance: sizeFont { struct Static { static var oncetoken: Int = 0 static var instance: sizeFont? = nil } _ = sizeFont.__once return Static.instance! }} 红线代码是Static.instance = sizeFont().
我不知道为什么我会得到这个,其他人都知道吗?
解决方法 静态在类变量中声明,导致var声明之外的每个人都不可达,只是将它移到外面....struct Static { static var oncetoken: Int = 0 static var instance: sizeFont? = nil}// example singleton swiftclass var sharedInstance: sizeFont { _ = sizeFont.__once return Static.instance!}... 总结 以上是内存溢出为你收集整理的ios – 使用未解析的标识符“静态”全部内容,希望文章能够帮你解决ios – 使用未解析的标识符“静态”所遇到的程序开发问题。
