Question

我正在调用 SOAP API ，我收到了 XML 格式的响应，我尝试通过设置 XML >委托。我没有调用委托方法的问题，这里是我调用的API和解析代码。

- (void)viewDidLoad {
[super viewDidLoad];

NSDictionary *dictionary = @{@"mobileuser3":@"loginUser"};
[[WMAPIClient sharedClient] loginAPI:@"/01/wsdl/LoginUserService" withParameters:dictionary withSuccessBlock:^(id responseObject){
    NSXMLParser *XMLParser = (NSXMLParser *)responseObject;
    [XMLParser setShouldProcessNamespaces:YES];
    XMLParser.delegate = self;
    [XMLParser parse];
}withFailureBlock:^(NSError *error) {
    UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Error Retrieving Data"
                                                        message:[error localizedDescription]
                                                       delegate:nil
                                              cancelButtonTitle:@"Ok"
                                              otherButtonTitles:nil];
    [alertView show];
}];
}

这是解析器委托方法

- (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName attributes:(NSDictionary *)attributeDict{
NSString *ele = elementName;
NSLog(@"elementName = %@, qName = %@",elementName,qName);}

- (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string{
NSLog(@"string = %@", string);

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

- (void) parserDidEndDocument:(NSXMLParser *)parser{
NSLog(@"End");
}

请帮我解决问题......提前致谢

据我所知，您收到的对象类型存在问题。 NSXMLParser初始化方法很少，最常见的方法是initWithData和initWithURL。

尝试添加这些行以进行修复;

NSString *xmlString = responseObject.responseString;
NSData *xmlData = [xmlString dataUsingEncoding:NSUnicodeStringEncoding];

然后使用initWithData选项。

NSXMLParser委托方法在iOS 8中不起作用
