Question

parserDidNotEndDocumentが呼び出されない、それは昨日働いていた、私は異なっていると思う唯一のことは、今私はxcode 4を使用しています。スローされるエラーはXML Parseでエラーです：操作を完了できませんでした。 （NSXMLParserErrorDomainエラー5）パースエラーを見つけるための

ソリューション：

- (void)parser:(NSXMLParser *)parser parseErrorOccurred:(NSError *)parseError 
{ 
    NSDictionary *userInfo = parseError.userInfo; 
    NSNumber *lineNumber = userInfo[@"NSXMLParserErrorLineNumber"]; 
    NSNumber *errorColumn = userInfo[@"NSXMLParserErrorColumn"]; 
    NSString *errorMessage = userInfo[@"NSXMLParserErrorMessage"]; 

    NSLog(@"Error occured in line %@ and column %@\nWith message: %@", lineNumber, errorColumn, errorMessage); 
}
