解决一个问题，郁闷好久的问题

在创建UIButton时，点击动作里老是读取不到成员变量。调试Ｎ次，一到读取那个列表时程序就直接退出。

-(void)selectCompany:(id)sender{
	int index = [sender tag];
	//NSLog(@"sender:%d",index);
	
	NSArray *company = [companyList objectAtIndex:index];
	//NSLog(@"selectCompany:name:%@,id:%@",[company valueForKey:@"name"],[company valueForKey:@"cid"]);
	CompanyMatchController *cMatch = [[CompanyMatchController alloc]initWithCidAndName:[company valueForKey:@"cid"] cName:[company valueForKey:@"name"]];
	[self.navigationController pushViewController:cMatch animated:YES];																													  
}

 就这是

NSArray *company = [companyList objectAtIndex:index];

这里程序就直接退出了。

经别人指数，因为你self.是对你那对象retain了一次,所以就好了

 

后来慢慢地检查成员变量的初始化。发现问题问题出自：

-(void)fetchData{
	[self removeAllView];
	companyList = [JSONParser loadData:@"http://3g.wapzq.com/odds/json/company.jsp" isAllValues:NO valueForKey:@"list"];
	[[WaitDialog sharedWaitDialog]setLoadingLabel:@"正在构造界面..."];
	[self makeView];
}

以下

 

companyList = [JSONParser loadData:@"http://3g.wapzq.com/odds/json/company.jsp" isAllValues:NO valueForKey:@"list"];

 要加上self.

self.companyList = [JSONParser loadData:@"http://3g.wapzq.com/odds/json/company.jsp" isAllValues:NO valueForKey:@"list"];

 重新编译，运行，哦野。解决了整一个上午的问题。
