swift中代理的声明：
@objc (ClassesViewDelegate)
public protocol ClassesViewDelegate : NSObjectProtocol {
//课节的点击事件
func classesView(number: String, name: String, sex : String) -> Void
}
@objc public weak var delegate : BJSCourseAllClassesViewDelegate?
self.delegate?. classesView(number: number, name: name, sex: sex)
OC中的实现：
<ClassesViewDelegate>
classesView.delegate = self;
- (void)classesViewWith number:(NSString *) number name:(NSString *) name sex:(NSString *) sex {
//代理实现
}
