介面呼叫引數只能是字串格式，返回格式支援3種（字串，陣列，DataSet）

需要引用第三方庫，包含（DataSet,PlatServinceDataParser,WebserviceCommon,WebServiceHelper,XMLArrayParser,XMLDataSetParser,XMLResultParser）

程式中引用2個即可

#import "WebServiceCommon.h"

#import"DataSet.h"

- (void)getwebserver

{

WebServiceCommon *webService=[[WebServiceCommonalloc]

//方法一，取返回字串

NSString *result= [webServicegetResultWithURL:@"http://116.6.52.27:91/webservice/caskaforescService.asmx"xmlNS:nilmethod:@"GetCarTypeTree"pars:nil];

    NSLog(@"%@",result);

    [result release];

//帶引數傳值呼叫方法

NSMutableDictionary *dic=[[NSMutableDictionaryalloc]initWithObjectsAndKeys:@"test2",

NSString *result2= [webServicegetResultWithURL:@"http://116.6.52.27:91/webservice/caskaforescService.asmx"xmlNS:nilmethod:@"GetClub"pars:dic];

    NSLog(@"%@",result2);

    [dic release

    [result2 release];

//方法二，取返回資料組

    NSArray *array=nil;

NSMutableDictionary *dic2=[[NSMutableDictionaryalloc]initWithObjectsAndKeys:@"...",@"VerifyCode", @"",@"objParams", @"20120615170225282486",@"sAccountBookID", @"XYTY124",@"productModel", @"馨原奕絨",@"brandName", nil];

    array=[webServicegetArrayWithURL:@"http://resourceservice.41go.cn/systemupdate.asmx"xmlNS:nilmethod:@"GetProductPriceInfoExt"pars:dic2];

NSLog(@"productmodel=%@;name=%@,key=%@",[arrayobjectAtIndex:2],[arrayobjectAtIndex:3],[arrayobjectAtIndex:10]);

//判斷資料中的空值（NSArray,NSMutableDictionary等）

    if ([array objectAtIndex:10]==[NSNullnull]) {

        NSLog(@"空值！");

    }

    [dic2 release];

//方法三，取返回DataSet

    [webServiceinitDataSetWithURL:@"http://resourceservice.41go.cn/systemupdate.asmx"xmlNS:nilmethod:@"GetYarnList"pars:nil];

    NSMutableDictionary *wb=[webService.myDataset.TablesobjectForKey:@"YarnList"];//YarnList表名，如果沒有命名則為Table

    NSInteger count=[[webService.myDataset.TablesobjectForKey:@"YarnList"]count];

    for (int ii=0; ii<count; ii++) {

        NSMutableDictionary *dictemp=[wb objectForKey:[NSStringstringWithFormat:@"%d",ii]];

NSLog(@"col1=%@;col2=%@;col3=%@",[dictempobjectForKey:@"C_AccountBookID"],[dictempobjectForKey:@"C_Name"],[dictempobjectForKey:@"C_YarnID"]);

    }

    [webService release];
