可利用反射機(jī)制獲取某個(gè)類的屬性及方法列表，代碼很簡單,重點(diǎn)用到class_copyPropertyList和class_copyMethodList，如下：

extension NSObject {
   
    func getPropertyNames(){
        
        var outCount:UInt32
        
        outCount = 0
        
        
        let propers:UnsafeMutablePointer<objc_property_t>! =  class_copyPropertyList(self.classForCoder, &outCount)
        
        
        let count:Int = Int(outCount);
        
        print(outCount)
        
        for i in 0...(count-1) {
            
            let aPro: objc_property_t = propers[i]
            
            let proName:String! = String(UTF8String: property_getName(aPro));
            
            print(proName)
            
        }
        
    }
    
    
    func getMethodNames(){
        
        var outCount:UInt32
        
        outCount = 0
        
        let methods:UnsafeMutablePointer<objc_property_t>! =  class_copyMethodList(self.classForCoder, &outCount)
        
        let count:Int = Int(outCount);
        
        print(outCount)
        
        for i in 0...(count-1) {
            
            let aMet: objc_property_t = methods[i]
            
            let methodName:String! = String(UTF8String: property_getName(aMet));
            
            print(methodName)
            
        }
        
    }
    
}
