如何使用ASIFormDataRequest从uiimagePickerController上传照片？

Question

我使用UIImagePickerController的委托来选择照片并将其放到服务器但问题是我不知道如何使用ASIFormDataRequest做到这一点我不知道应该使用哪个键作为info参数？

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{

NSString *str = [NSString stringWithFormat:@"http://www.siteweb.com/api/v2/businesses/%@/pics.xml",entry.permalink];
NSURL *url = [NSURL URLWithString:str];
ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:url];
request.delegate = self;

[request startAsynchronous];

[self dismissModalViewControllerAnimated:YES];
}

Answer 1

像这样：

  

[request addFile：（NSString *）filePath forKey：（NSString *）key];

事先得到这样的图像：

  

UIImage * image =（UIImage *）[info   valueForKey：UIImagePickerControllerOriginalImage];

     

[UIImageJPEGRepresentation（image，1.0）writeToFile：filePath   原子：YES];
