推荐答案

我想知道确切的图像名称不会成为问题，而是为获取的图像获取唯一名称将解决您的目的这样您就可以在服务器上传图像并通过其名称跟踪它。可能这可以帮到你

I guess knowing the exact image name would not be an issue rather getting a unique name for the picked image would solve your purpose so that you can upload the image on server and track it via its name. May be this can help you

NSMutableString *imageName = [[[NSMutableString alloc] initWithCapacity:0] autorelease];

CFUUIDRef theUUID = CFUUIDCreate(kCFAllocatorDefault);
if (theUUID) {
    [imageName appendString:NSMakeCollectable(CFUUIDCreateString(kCFAllocatorDefault, theUUID))];
            CFRelease(theUUID);
}
[imageName appendString:@".png"];

从Picker中选择图像后，您可以生成唯一名称并将其指定给Picked图像。
干杯

After you pick the image from Picker you can generate a unique name and assign it to the Picked image. Cheers
