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;
