如何将NSMutableData转换为视图中的图像？-HowdoIturnanNSMutableDataintoanimageinaview?

I downloaded a .jpg file from the Internet with this code:

我使用以下代码从Internet下载了.jpg文件:

NSURLRequest *theRequest=[NSURLRequest requestWithURL:[NSURL URLWithString:@"http://cvcl.mit.edu/hybrid/cat2.jpg"]];
NSURLConnection *theCOnnection=[[NSURLConnection alloc] initWithRequest:theRequest delegate:self];
receivedData=[[NSMutableData data] retain]; // etc etc

Everything works fine. I just don't know how to handle the data. Say I created an image view in IB, how would I go about displaying the image? Here's the last bit:

一切正常。我只是不知道如何处理数据。假设我在IB中创建了一个图像视图,我将如何显示图像?这是最后一点:

- (void)connectionDidFinishLoading:(NSURLConnection *)connection
{
    // ******do something with the data*********...but how  
    NSLog(@"Succeeded! Received %d bytes of data",[receivedData length]);

    // release the connection, and the data object
    [connection release];
    [receivedData release];
}

2 个解决方案

NSImage *image = [[NSImage alloc] initWithData:receivedData];
[imageView setImage:image];
[image release];
