通过iOS获取Facebook图片的问题 [英] Problem getting Facebook pictures via iOS

问题描述

我试图通过iOS上的Facebook连接来获取事件和个人资料图片，
我已经提出了以下要求：

  [facebook requestWithGraphPath：@me / pictureandDelegate：self]; 
  

和响应处理方法：

<$ p $（$）$（$）$（$）$（$）$（$）$（$）$（$）$（$）$（$）$ ;

NSData * data = [NSData dataWithContentsOfURL：[NSURL URLWithString：url]];

imageView.image = [UIImage imageWithData：data];
}

它不会工作，结果变量类型是NSConcreteMutableData和url变量值为空。

请帮助:)
谢谢。

解决方案

NSConcreteMutableData是实际的图像数据，而不是其URL。所有你需要的是

 （void）request：（FBRequest *）request didLoad：（id）result {
 imageView .image = [UIImage imageWithData：result]; 
} 
  

I'm trying to fetch events and profile pictures via Facebook connect on iOS, I've made for example the request:

[facebook requestWithGraphPath:@"me/picture" andDelegate:self];

and the response handling method:

(void)request:(FBRequest *)request didLoad:(id)result {

    NSString *url = [[NSString alloc] initWithData:result encoding:NSUTF8StringEncoding];

    NSData *data = [NSData dataWithContentsOfURL:[NSURL URLWithString:url]];

    imageView.image = [UIImage imageWithData:data];
}

and it won't work, the result variable type is NSConcreteMutableData and the url variable value is null.

help please :) Thanks.

解决方案

The NSConcreteMutableData is the actual image data, not its URL. All you needed was

(void)request:(FBRequest *)request didLoad:(id)result {
    imageView.image = [UIImage imageWithData:result];
}
