这类例子用于类var.不要包含bundle的名称。

extension NSObject {
    class var className: String {
        return "\(self)"
    }
}

你也可以使用镜子:

let vc = UIViewController()

String(Mirror(reflecting: vc).subjectType)

注意:此方法也可用于结构和枚举。有一个displayStyle指示结构的类型:

Mirror(reflecting: vc).displayStyle

返回值是一个枚举，所以你可以:

Mirror(reflecting: vc).displayStyle == .Class

方式1:

print("Class: \(String(describing: self)), Function: \(#function), line: \(#line)")

输出:

Class: <Test.ViewController: 0x7ffaabc0a3d0>, Function: viewDidLoad(), line: 15

方式2:

print("Class: \(String(describing: type(of: self))), Function: \(#function), line: \(#line)")

输出:

Class: ViewController, Function: viewDidLoad(), line: 16

试着反映了()。类self或实例dynamicType的摘要。在获取dynamicType之前解开可选项，否则dynamicType是可选包装器。

class SampleClass { class InnerClass{} }
let sampleClassName = reflect(SampleClass.self).summary;
let instance = SampleClass();
let instanceClassName = reflect(instance.dynamicType).summary;
let innerInstance = SampleClass.InnerClass();
let InnerInstanceClassName = reflect(innerInstance.dynamicType).summary.pathExtension;
let tupleArray = [(Int,[String:Int])]();
let tupleArrayTypeName = reflect(tupleArray.dynamicType).summary;

摘要是描述了泛型类型的类路径。要从摘要中获得简单的类名，请尝试此方法。

func simpleClassName( complexClassName:String ) -> String {
    var result = complexClassName;
    var range = result.rangeOfString( "<" );
    if ( nil != range ) { result = result.substringToIndex( range!.startIndex ); }
    range = result.rangeOfString( "." );
    if ( nil != range ) { result = result.pathExtension; }
    return result;
}

我在Swift 2.2中使用它

guard let currentController = UIApplication.topViewController() else { return }
currentController.classForCoder.description().componentsSeparatedByString(".").last!
