NSURLConnection和UITableView的delegate执行先后问题的解决方法

参考：http://stackoverflow.com/questions/12778213/uitableview-delegate-fires-nsurlconnection-delegate

一个ViewController同时包含NSURLConnection和UITableView的delegate时，无论怎样都会优先执行UITableView的delegate这就会导致dataSource出问题，那么解决方案就是：

didRecieveData might be called more than once, and does not indicates that all data is fetched. You should implement a private property on your class such as;

@property (nonatomic,retain) NSMutableData tableData;

and on your didRecieveData;

-(void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data{   [self.tableData appendData:data];}

After that when your connection is closed

-(void)connectionDidFinishLoading:(NSURLConnection *)connection{    // use tableData and refresh table...    [self.tableView reloadData];}
