Http get 请求
复制代码 代码如下:
// 组合一个搜索字符串
NSString *urlStr = [NSString stringWithFormat:@"http:///s?wd=%@", @"php"];
NSURL *url = [NSURL URLWithString:urlStr];

NSURLRequest *request = [NSURLRequest requestWithURL:url];

//发起请求，定义代理
[NSURLConnection connectionWithRequest:request delegate:self];

}

// 分批返回数据
- (void)connection:(NSURLConnection *) connection didReceiveData:(NSData *)data {
[_data appendData:data];
NSLog(@"%@", _data);
}

// 数据完全返回完毕
- (void)connectionDidFinishLoading:(NSURLConnection *)connection {
NSString *dataString = [[NSString alloc] initWithData:_data encoding:NSUTF8StringEncoding];
NSLog(@"%@", dataString);
}
