可用 xpath ，html解析lib， 下面为方法，xpath路径可专门另研究。 NSData *htmlData = [[response dataUsingEncoding:NSUTF8StringEncoding] retain]; TFHpple *xpathParser = [[TFHpple alloc] initWithHTMLData:htmlData]; NSArray *arrayTitle = [xpathParser searchWithXPathQuery:@"//div[@class= 'item-box']/h3/a/attribute::title"]; NSArray *arrayPic = [xpathParser searchWithXPathQuery:@"//div[@class= 'item-box']/div[@class= 'pic']/p/a/span/img/attribute::src"]; NSArray *arrayUrl = [xpathParser searchWithXPathQuery:@"//div[@class= 'item-box']/h3/a/attribute::href"]; NSArray *arrayPrice = [xpathParser searchWithXPathQuery:@"//div[@class= 'col price']"];//价格 //此陣列為篩選結果 //TFHpple使用XPath來篩選，XPath介紹(W3C)：http://www.w3school.com.cn/xpath/index.asp for(int i = 0; i < [arrayTitle count]; i++) { NSString *title = [[arrayTitle objectAtIndex:i] content]; NSString *pic = [[arrayPic objectAtIndex:i] content]; NSString *url = [[arrayUrl objectAtIndex:i] content]; NSString *price = [[arrayPrice objectAtIndex:i] content]; NSMutableDictionary* item_dic=[[NSMutableDictionary alloc] init]; [item_dic setValue:title forKey:ITEM_TITLE]; [item_dic setValue:pic forKey:ITEM_PIC]; [item_dic setValue:url forKey:ITEM_URL]; [item_dic setValue:price forKey:ITEM_PRICE]; [self.item_Array addObject:item_dic]; } [xpathParser release]; [htmlData release];
