NSURLConnection 异步请求能不能封装诚一个公用的类？
异步请求能不能封装诚一个公用的类？每个页面都要copy一下几个方法，感觉很麻烦，
但是如果封装诚一个公共的类，又如何通知请求的页面返回数据？
//发送异步get请求
-(IBAction)BeginRequest:(NSString *)urlRequest
{
}
- (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response
{
[receivedData setLength:0];
}
//接收NSData数据
- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data
{
[receivedData appendData:data];
}
- (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error
{
}
//接收完毕,显示结果
- (void)connectionDidFinishLoading:(NSURLConnection *)connection
{
}
