我相信这对你的专家来说非常简单。设置了SUDZC,一切似乎都正常工作,但是当一个值返回给委托时,它为空。 NSLog显示正确的XML响应,所以我知道它正常工作,但代码中的值显示为null。 SUDZC附带一个示例程序,这就是它的运行方式。我在网络服务“WhatsYourFavoriteMovie”上创建了一个测试功能,它返回“Pulp Fiction”。日志记录清楚地显示返回的值。为什么是最终值(null)?请帮忙,谢谢。
所以我打电话给...
[service WhatsYourFavoriteMovie:self action:@selector(WhatsYourFavoriteMovieHandler:) userid: 1];
然后当Web服务响应时,它会转到...
// Handle the response from WhatsYourFavoriteMovie.
- (void) WhatsYourFavoriteMovieHandler: (id) value {
// Handle errors
if([value isKindOfClass:[NSError class]]) {
NSLog(@"%@", value);
return;
}
// Handle faults
if([value isKindOfClass:[SoapFault class]]) {
NSLog(@"%@", value);
return;
}
// Do something with the NSString* result
NSString* result = (NSString*)value;
NSLog(@"WhatsYourFavoriteMovie returned the value: %@", result);
}
然而“值”和“结果”始终为“空”...正如您在下面的NSLog输出中所看到的那样,它在标签中返回“Pulp Fiction”。我哪里错了?

再次,正如您在日志中看到的那样,它从服务器获得了“纸浆小说”的值,但是日志的最后一行表示它返回值“null”。请帮我!!谢谢。

尝试在didrecivedata中NSLog响应。在SoapRequest.m类中
-(void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)value {
NSString *str=[[NSString alloc]initWithData:value encoding:NSUTF8StringEncoding];
NSLog(@"data receives %@",str);
}
然后你会知道确切的问题是什么。 在完成此操作后发布回复,我们会帮助您。

如果您使用ARC版本,请在SoapRequest中更改行
CXMLNode* element = [[Soap getNode: [doc rootElement] withName:@"Body"] childAtIndex:0];
带
CXMLNode* element = [[Soap getNode: [doc rootElement] withName:@"soap:Body"] childAtIndex:0];
