Loading NSData into a UIWebView
提问by Greg
In my web browser, I am trying to load a UIWebViewwith NSDataobtained from a NSURLConnection. When I try to load it into the UIWebView, instead of the site, it comes up with the HTML plain text.
在我的网页浏览器，我试图加载UIWebView与NSData从获得的NSURLConnection。当我尝试将它加载到UIWebView, 而不是站点时，它会出现 HTML 纯文本。
Here is my code:
这是我的代码：
in viewDidLoad:
在 viewDidLoad:
NSURLRequest *request = [NSURLRequest requestWithURL: [NSURL URLWithString:@"http://www.msn.com"]];
[NSURLConnection connectionWithRequest: request delegate:self];
later in the code:
稍后在代码中：
-(void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data
{
webdata = [NSMutableData dataWithData: data];
}
-(void)connectionDidFinishLoading:(NSURLConnection *)connection
{
[webview loadData:webdata MIMEType: @"text/html" textEncodingName: @"UTF-8" baseURL:nil];
}

You are not appending data that you are receiving. Use this piece of code
您没有附加您正在接收的数据。使用这段代码
-(void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data{
if (webdata == nil) {
webdata = [[NSMutableData alloc] init];
}
[webdata appendData:data];
}
This method might be called once or more times depending upon your data length. So instead of assigning new data to your ivar, append your data to it so that you have the full response not the last packet of data received.

Updated
Or use like this.
根据您的数据长度，此方法可能会被调用一次或多次。因此，不要将新数据分配给您的 ivar，而是将您的数据附加到它，以便您获得完整的响应，而不是收到的最后一个数据包。
-------------------------------------------------- -------------------------------------------------- --------------------------------
更新
或这样使用。
- (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response{
webdata = [[NSMutableData alloc] init];
}
-(void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data{
[webdata appendData:data];
}
-(void)connectionDidFinishLoading:(NSURLConnection *)connection{
[mWebView loadData:webdata MIMEType: @"text/html" textEncodingName: @"UTF-8" baseURL:nil];
}
