                        timeDuration =                         {
                            text = "5 days";
                        };
                        turnChangesIn =                         {
                            text = 0;
                        };
                    }
                );
                "xmlns:ns2" = "http://services.tgs.com/";
            };
        };
        "xmlns:S" = "http://schemas.xmlsoap.org/soap/envelope/";
    };
}

我需要key＆＃34; matchStartThresholdTime＆＃34;的值。我这样做：

NSDictionary *dictResult = [XMLReader dictionaryForXMLString:responseString error:nil];
                NSDictionary *Enveloper  = [dictResult objectForKey:@"S:Envelope"];
                NSDictionary *Body       = [Enveloper objectForKey:@"S:Body"];
                NSDictionary *profileDetails = [Body objectForKey:@"ns2:getMatchListResponse"];
                NSMutableArray *items = [profileDetails objectForKey:@"item"];

             //  NSLog(@"items===>%@",items);

               NSDictionary *temp1;

               for(temp1 in items)
               {

                   thresholdTime = [NSString stringWithFormat:@"%@",[[temp1 objectForKey:@"matchStartThresholdTime"]objectForKey:@"text"]];...thresholdTime is NSString object.......and this line causes exception

                   //NSLog(@"time is===>%@",[[temp1 objectForKey:@"matchStartThresholdTime"]objectForKey:@"text"]);
               }

这里有什么问题？

Temp1包含您期望的NSString对象，而不是NSDictionary。

在处理JSON时，最好（双）检查收到的对象是否真的是您期望的类型。始终使用

if ([temp1 isKindOfClass:[NSDictionary class]]) ...

左右。
