将 UIImage 发布到网络上

Question

我刚刚开始从事 xcode 业务，到目前为止一切顺利，除了这个小细节：我不知道如何将 UIImage 发布到网络。在过去的三天里我一直在尝试一切（阅读和查询了很多）但没有成功。我想答案就在我眼皮子底下，仍然……不走运。

我把我写的代码（在 Objective-C 和 php 中）留在这里：它根​​本不起作用！没有上传图像。请问有人可以帮助我吗？

//objective-C

NSData *theData = UIImagePNGRepresentation(photo.image);  
NSString *urlString = @"http://www.testes01.com/newsie/receberprofilephoto.php";  
NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];  
[request setURL:[NSURL URLWithString:urlString]];  
[request setHTTPMethod:@"POST"];  
NSString *boundary = [NSString stringWithString:@"---------------------------14737809831466499882746641449"];  
NSString *contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@",boundary];  
[request addValue:contentType forHTTPHeaderField: @"Content-Type"];  
NSMutableData *body = [NSMutableData data];  
[body appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n",boundary]   dataUsingEncoding:NSUTF8StringEncoding]];  
[body appendData:[[NSString stringWithString:@"Content-Disposition: form-data; name=\"file\"; filename=\"iphoneimage.png\"\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];  
[body appendData:[[NSString stringWithString:@"Content-Type: application/octet-stream\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];  
[body appendData:[NSData dataWithData:theData]];  
[body appendData:[[NSString stringWithFormat:@"\r\n--%@--\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];  
[request setHTTPBody:body];  
NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];  
NSString *returnString = [[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding];  

//PHP

move_uploaded_file($_FILES["file"][tmp_name], "fotosprofile/" . $_FILES["file"]["name"]);  

提前致谢。

这是在网络上上传图像的代码
self.image 是我的 uiimage 对象，我已将其设置为属性并合成它。然后将您的图像放入 self.image 中：-

NSData *imagedata=[NSData dataWithData:UIImagePNGRepresentation(self.image)];
    NSString *base64string=[imagedata base64EncodedString];
    NSString *str = [NSString stringWithFormat:@"http://www.testes01.com/newsie/receberprofilephoto.php"];
    NSURL *url = [NSURL URLWithString:[str stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];
    ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:url];
    [request setPostValue:base64string forKey:@"imagedata"];
    [request setRequestMethod:@"POST"];
    [request setDelegate:self];
    [request startSynchronous];
    NSLog(@"responseStatusCode %i",[request responseStatusCode]);
    NSLog(@"responseStatusString %@",[request responseString]);

我希望这可以帮助您！！！！
