我有以下方法，我还有另一种方法可以调用此方法，但还没有成功。
- (void) parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName
namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qualifiedName
attributes:(NSDictionary *)attributeDict{
if ([elementName isEqualToString:@"isphone-config"]) {
Pusername = [attributeDict valueForKey:@"authentication_username"];
Ppassword = [attributeDict valueForKey:@"authentication_password"];
Pidentity = [attributeDict valueForKey:@"sip_identity"];
Pdomain = [attributeDict valueForKey:@"domain"];
Pprotocol = [attributeDict valueForKey:@"protocol"];
Pudpport = [attributeDict valueForKey:@"registrar_port"];
Ptcpport = [attributeDict valueForKey:@"listening_port"];
NSLog(@"Title: %@, ID: %@", Pusername, Ppassword);
}
}
}
我通过以下方法调用它..
NSString* username = [[NSUserDefaults standardUserDefaults] stringForKey:@"username_preference"];
NSString* accountPassword = [[NSUserDefaults standardUserDefaults] stringForKey:@"password_preference"];
NSString* urlString = [NSString stringWithFormat:@"https://%@:%@@test.com/test.php",username,accountPassword];
NSURLRequest* request = [NSURLRequest requestWithURL:[NSURL URLWithString:urlString]];
NSData *response = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
parser = [[NSXMLParser alloc] initWithData: response];
NSLog(@"at parser %@", parser);
[parser setDelegate:self];
我在调用解析器的代码的最后一行遇到问题。我假设这一行将调用方法解析器，如果我错了请纠正我。我不知道我必须导入、包含或实现哪些文件、接口(interface)和类。
最佳答案
使用 NSXMLParser 进行 XML 解析要困难得多，查看 Apple 的示例“earthquakes”。
相反，我建议您使用另一个 XML 解析器。例如，this one :
