92 }
93
94 end 运行效果 三、对xib进行连线示例 1.连线示例 新建一个xib对应的视图类继承自Uiview 在xib界面右上角与新建的视图类进行关联 把xib和视图类进行连线 2.连线后的代码示例 YYViewController.m文件代码如下 1 //2 // YYViewController.m3 // 10-xib文件的使用4 //5 // Created by apple on 14-5-24.6 // Copyright (c) 2014年 itcase. All rights reserved.7 //8 9 #import YYViewController.h
