iphone - 将图片从本地机器发布到 Facebook 的用户墙

Question

如何使用slRequestFacebook 用户墙发布图像？

-(IBAction)done
{
    NSString *message=@"hello";

    NSString *picture=[[NSBundle mainBundle]pathForResource:@"4" ofType:@"jpg"];

    NSDictionary *params = [NSDictionary dictionaryWithObjectsAndKeys:message, @"message",picture,@"picture", nil];
}

Answer 1

尝试使用这个，你知道你从 NSBundle 获取路径而不是图像，所以你需要从图片路径获取第一张图像，然后执行它。

NSString *picture=[[NSBundle mainBundle]pathForResource:@"4" ofType:@"jpg"];
 UIImage *image = [UIImage imageWithContentsOfFile:picture];

       NSMutableDictionary* params = [[NSMutableDictionary alloc] initWithObjectsAndKeys:message, @"message",image, @"picture",nil];

Answer 2

试试这个，使用@"source"密钥发布图片

 NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys:_image, @"source",msg,@"name",nil];
//_image is UIImage
