浅谈iOS设计中用XML解析美团外卖地址信息并在tableView上显示

思路与步骤：

1、制作.XML文件（美团外卖）

=====》

======》点击“获取城市列表”

====》点击网址

====》进入页面把所有的内容复制到编辑文本  做成.xml 类型的文件

做好.xml文件后  把它拖入工程中就可以进行解析了

如果网络状态非常好的话 ， 也可以不用制作.xml文件  直接对网址进行网络XML解析就行；

下面我主要介绍对.xml文件的解析(xml解析)

代码实现如下；

1.

  AppDelegate.h

#import <UIKit/UIKit.h>
#import "ShowTableViewController.h"
@interface AppDelegate : UIResponder <UIApplicationDelegate>
@property (strong, nonatomic) UIWindow *window;

@end

 

AppDelegate.m

#import "AppDelegate.h"

@interface AppDelegate ()

@end

@implementation AppDelegate

 

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    self.window.rootViewController=[[UINavigationController alloc]initWithRootViewController:[[ShowTableViewController alloc]initWithStyle:UITableViewStyleGrouped]];
    return YES;

}

ShowTableViewController.h

#import <UIKit/UIKit.h>
#import "SecondTableViewController.h"
@interface ShowTableViewController : UITableViewController<NSXMLParserDelegate>
//全局字符串  显示字典的Value值
@property(strong,nonatomic)NSString *string;
//用于显示所有数据的集合
@property(strong,nonatomic)NSMutableArray *Array;
//用于封装集合元素

@property(strong,nonatomic)NSMutableDictionary *Dictionary;
