/**
注意点: 1.看 GIF 效果图.
2.看连线视图的效果图.
3.看实现代码(直接复制实现效果).
4.看实现代码MVC架构
*/
一、GIF 效果图:
二、连线视图的效果图:
图1:
图2:
图3:
三、实现代码:
=======
================================
=======
1.AppDelegate.m 中的代码
#import"AppDelegate.h"
#import"ViewController.h"//主控制器
@interfaceAppDelegate()
@end
@implementationAppDelegate
- (BOOL)application:(UIApplication*)application didFinishLaunchingWithOptions:(NSDictionary*)launchOptions {
//初始化
ViewController*vc = [[ViewControlleralloc]init];
//导航控制器
UINavigationController*nvc = [[UINavigationControlleralloc]initWithRootViewController:vc];
//添加图
self.window.rootViewController= nvc;
returnYES;
}
================================
=======
2.导入第三方数据库 FMDB 框架包
下载地址:https://github.com/ccgus/fmdb
注意:要导入 libsqlite3.tbd 包 (详情请看上面图3)
================================
=======
3.在 Other 模块中添加业务处理层处理 SQLite 语句
注意:如果现在拷贝到项目会报错-->原因是其他 MVC 模块中的类没有实现
