[操作系统]iOS xml文件的解析方式 XMLDictionary,GDataXMLNode,NSXMLParser


iOS9之后,默认网络请求是https,所有我们要设置一下网络安全,具体设置如下

1.第三方类库 

下载地址:

所用到的http://www.meituan.com/api/v1/divisions?mtt=1.help%2Fapi.0.0.im7eandj

效果如下:

代码实现:

根视图:

第二个视图:secondViewController.h

#import <UIKit/UIKit.h>@interface secondViewController : UIViewController@property(nonatomic,strong)NSDictionary *location;@property(nonatomic,strong)NSString *title;@end

secondViewController.m文件

#import "secondViewController.h"@interface secondViewController ()@property(nonatomic,strong)UILabel *latitudeName;@property(nonatomic,strong)UILabel *longitudeName;@property(nonatomic,strong)UILabel *timezoneName;@property(nonatomic,strong)UILabel *latitude;@property(nonatomic,strong)UILabel *longitude;@property(nonatomic,strong)UILabel *timezone;@end@implementation secondViewController- (void)viewDidLoad {  [super viewDidLoad];  [self setKongjian];  self.title=[NSString stringWithFormat:@"%@的经纬度",self.title];    self.view.backgroundColor=[UIColor colorWithRed:0.148 green:1.000 blue:0.946 alpha:1.000];  }-(void)setKongjian{  self.latitudeName=[[UILabel alloc]initWithFrame:CGRectMake(100, 200, 100, 30)];  self.latitudeName.text=@"纬度:";  self.latitude=[[UILabel alloc]initWithFrame:CGRectMake(150, 200, 200, 30)];  self.latitude.text=self.location[@"latitude"];      self.longitudeName=[[UILabel alloc]initWithFrame:CGRectMake(100, 250, 100, 30)];  self.longitudeName.text=@"经度:";  self.longitude=[[UILabel alloc]initWithFrame:CGRectMake(150, 250, 200, 30)];  self.longitude.text=self.location[@"longitude"];    self.timezoneName=[[UILabel alloc]initWithFrame:CGRectMake(100, 300, 100, 30)];  self.timezoneName.text=@"时区:";  self.timezone=[[UILabel alloc]initWithFrame:CGRectMake(150, 300, 200, 30)];  self.timezone.text=self.location[@"timezone"];      [self.view addSubview:self.latitudeName];  [self.view addSubview:self.longitudeName];  [self.view addSubview:self.timezoneName];  [self.view addSubview:self.latitude];  [self.view addSubview:self.longitude];  [self.view addSubview:self.timezone];}- (void)didReceiveMemoryWarning {  [super didReceiveMemoryWarning];  // Dispose of any resources that can be recreated.}/*#pragma mark - Navigation// In a storyboard-based application, you will often want to do a little preparation before navigation- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {  // Get the new view controller using [segue destinationViewController].  // Pass the selected object to the new view controller.}*/@end

 

2.GData

具体配置过程如下
