代理声明：

//oc调用代理@objc(NurseListCellDelegate)protocol NurseListCellDelegate  : NSObjectProtocol{    func nurseListCellDidClickedDeleteNurseAction(nurseListCell: NurseListCell)    func nurseListCellDidClickedFreezeNurseAction(nurseListCell: NurseListCell)}class NurseListCell: UITableViewCell{        weak var delegate : NurseListCellDelegate?}

代理触发

func delNurseAction() {        if (delegate != nil && (delegate?.respondsToSelector(Selector("nurseListCellDidClickedDeleteNurseAction")))!) {            delegate!.nurseListCellDidClickedDeleteNurseAction(self)        }    }    func freezeNurseAction() {        if (delegate != nil && (delegate?.respondsToSelector(Selector("nurseListCellDidClickedFreezeNurseAction")))!) {            delegate!.nurseListCellDidClickedFreezeNurseAction(self)        }    }

代理使用

//在oc中创建后，直接添加代理nurseCell.delegate = self;//实现- (void)nurseListCellDidClickedDeleteNurseAction:(NurseListCell *)nurseListCell{    NSLog(@"%s",__func__);}- (void)nurseListCellDidClickedFreezeNurseAction:(NurseListCell *)nurseListCell{    NSLog(@"%s",__func__);}
