objective-c - swift 转到 objective-c 设置图像舞会Facebook登录

如何在目标C中编写以下代码：

let strPictureURL: String = (result.objectForKey("picture")?.objectForKey("data")?.objectForKey("url") as? String)!
self.ivUserProfileImage.image = UIImage(data: NSData(contentsOfURL: NSURL(string: strPictureURL)!)!)

我一直试图在目标C中重写代码，但找不到从NSString设置图像的方法。到目前为止，我已经做到了：

NSString *strPictureURL = [[[result objectForKey:@"picture"] objectForKey: @"data"] objectForKey:@"url"];

最佳答案

NSString *strPictureURL = [[[result objectForKey:@"picture"] objectForKey: @"data"] objectForKey:@"url"];
self.ivUserProfileImage.image = [UIImage imageWithData:[NSData dataWithContentsOfURL:[NSURL URLWithString:strPictureUrl]]];
