在soap web服务中，如何获取用户数组中的值并将其存储在不同的字符串中。我必须在NSString中存储标题，名字等。如何在目标c中做到这一点？

   - (IBAction)loginbutton:(id)sender {
   //calling the soap message
    NSString *userid = _username.text;
    NSString *password = _password.text;
   soapMessage = [NSString stringWithFormat:@"my soap url",userid,password];
    NSURL *url = [NSURL URLWithString:@"my soap url"];
    NSMutableURLRequest *theRequest = [NSMutableURLRequest requestWithURL:url];
    NSString *msgLength = [NSString stringWithFormat:@"%d", [soapMessage length]];
    [theRequest addValue:@"www.etownpanchayat.com" forHTTPHeaderField:@"Host"];
    [theRequest addValue: @"text/xml; charset=utf-8" forHTTPHeaderField:@"Content-Type"];
    [theRequest addValue: @"http://tempuri.org/LoginDetails" forHTTPHeaderField:@"SOAPAction"];
    [theRequest addValue: msgLength forHTTPHeaderField:@"Content-Length"];
    [theRequest setHTTPMethod:@"POST"];
    [theRequest setHTTPBody: [soapMessage dataUsingEncoding:NSUTF8StringEncoding]];
    //initiate the request
    NSURLConnection *connection =[[NSURLConnection alloc] initWithRequest:theRequest delegate:self];
    if(connection)
    {
        webResponseData = [NSMutableData data] ;
    }
    else
    {
        NSLog(@"Connection is NULL");
    }
}
-(void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response {
    [self.webResponseData  setLength:0];
}
-(void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data {
    [self.webResponseData  appendData:data];
}
-(void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error {
    NSLog(@"Some error in your Connection. Please try again.");
}
-(void)connectionDidFinishLoading:(NSURLConnection *)connection {
    NSLog(@"Received %d Bytes", [webResponseData length]);
    NSString *theXML = [[NSString alloc] initWithBytes:
                        [webResponseData mutableBytes] length:[webResponseData length] encoding:NSUTF8StringEncoding];

    NSLog(@"%@",theXML);

    //now parsing the xml

    NSData *myData = [theXML dataUsingEncoding:NSUTF8StringEncoding];

    NSXMLParser *xmlParser = [[NSXMLParser alloc] initWithData:myData];

    //setting delegate of XML parser to self
    xmlParser.delegate = self;

    // Run the parser
    @try{
        BOOL parsingResult = [xmlParser parse];
        NSLog(@"parsing result = %hhd",parsingResult);
    }
    @catch (NSException* exception)
    {
        UIAlertView* alert = [[UIAlertView alloc]initWithTitle:@"Server Error" message:[exception reason] delegate:self cancelButtonTitle:@"OK" otherButtonTitles: nil];
        [alert show];
        return;
    }
}
-(void) parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName
  namespaceURI:(NSString *)namespaceURI qualifiedName:
(NSString *)qName attributes:(NSDictionary *)attributeDict
{
    currentElement = elementName;
    NSLog(@" %@ the current .......",currentElement);

}
- (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName
  namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName
{
    NSLog(@"Parsed Element : %@", currentElement);
}

- (void)parser:(NSXMLParser *)parser foundCharacters:(NSArray *)userArray
{
    if ([currentElement isEqualToString:@"LoginDetailsResult"]) {
        NSLog(@"%@ the out value is ",userArray);
       //In user array i am getting the following response [{"Title":"Mrs","FirstName":"Pavithra","LastName":"(null)","ContactNo":"8073243634","EmailId":"test123456","DoorNo":"","StreetName":"","City":"v","Pincode":"v","State":"b","Country":"v","Address":"vb","UserId":526722}]

        }

}

首先创建一个名为UserModel的新类，继承自NSObject并在UserModel.h类中编写以下代码

@interface UserModel : NSObject
@property (nonatomic, strong) NSString* title;
@property (nonatomic, strong) NSString* firstName;
@property (nonatomic, strong) NSString* lastName;
@property (nonatomic, strong) NSString* contactNo;
@property (nonatomic, strong) NSString* emailId;
@property (nonatomic, strong) NSString* doorNo;
@property (nonatomic, strong) NSString* streetName;
@property (nonatomic, strong) NSString* city;
@property (nonatomic, strong) NSString* pincode;
@property (nonatomic, strong) NSString* state;
@property (nonatomic, strong) NSString* country;
@property (nonatomic, strong) NSString* address;
@property (nonatomic, strong) NSString* userId;

- (id) initWithDictionary:(NSDictionary*)dict;

在UserModel.m类中添加此代码

- (id) initWithDictionary:(NSDictionary*)dict
{
    self = [super init];
    if (self)
    {
        self.title = dict[@"Title"];
        self.firstName = dict[@"FirstName"];
        self.lastName = dict[@"LastName"];
        self.contactNo = dict[@"ContactNo"];
        self.emailId = dict[@"EmailId"];
        self.doorNo = dict[@"DoorNo"];
        self.streetName = dict[@"StreetName"];
        self.city = dict[@"City"];
        self.pincode = dict[@"Pincode"];
        self.state = dict[@"State"];
        self.country = dict[@"Country"];
        self.address = dict[@"Address"];
        self.userId = dict[@"UserId"];
    }
    return self;
}

在您正在解析的类中导入UserModel.h然后在您已收到字典数组的代码中获取Global（您也可以取本地取决于您正在应用的逻辑）

#import UserModel.h
UserModel* _userObj

- (void)parser:(NSXMLParser *)parser foundCharacters:(NSArray *)userArray
{
    if ([currentElement isEqualToString:@"LoginDetailsResult"])
   {
        NSLog(@"%@ the out value is ",userArray);
       for (NSDictionary* dict in  modelsListArray)
         {
            //UserModel* obj = [[UserModel alloc]  initWithDictionary:dict]; 
            _userObj = [[UserModel alloc]  initWithDictionary:dict]
         }
    }
}

现在如果您在UiTextFields用户的UIlabel上设置数据以下设置数据的代码

self.firstNameLabel.text = _userObj. firstName;
self.lastNameLabel.text = _userObj. lastName;

这是MVC设计模式。尝试始终遵循此模型。

Answer 2

我可以说使用模型类来更好地处理这类数据。创建NSObject类，说“User”并将所有这些属性添加到类中。使用任何JSON解析器（如SBJSON），将响应转换为模型类，以便获得模型类对象的数组。然后，您将能够非常轻松地处理此响应（user.title，user.firstname等。）

Answer 3

首先：字典写错了你可以试试这个：

NSArray * array = @ [@ {@“Title”：@“Mrs”，@“UserId”：@ 526722}];的NSLog（@ “％@”，数组）;希望可以帮助你;

如何从Objective-C中获取基于对象的数组的值？
