SDWebImage not working

I'm trying use SDWebImage for downloading image from a web. But it's not working. How can I fix it?

DetailView.m:

#import "DetailViewController.h"
#import "UIImageView+WebCache.h"

- (void)viewDidLoad {
    [super viewDidLoad];

    [self.imageView sd_setImageWithURL: [NSURL URLWithString:_downloadedimage]
                   placeholderImage:[UIImage imageNamed:@"image.png"]];

    self.imageView.frame = (CGRect){.origin=CGPointMake(1.0f, 1.0f), .size=_img.size};  // I think what error here
    [self.scrollView addSubview:self.imageView];

    self.scrollView.contentSize = _img.size; // and here?
}

Thanks for your help.

Looks like you not initialized imageview. Try to do it before.

- (void)viewDidLoad
{
    [super viewDidLoad];
    if (self.imageView == nil)
        self.imageView = [[UIImageView alloc] init];
    [self.imageView sd_setImageWithURL: [NSURL URLWithString:_downloadedimage] placeholderImage:[UIImage imageNamed:@"image.png"]];
    //...
}

Firstly Import the lib.

#import <SDWebImage/UIImageView+WebCache.h>

and then add this line 

[self.imageView setImageWithURL:[NSURL URLWithString:@"urlString" placeholderImage:[UIImage imageNamed:@"abc.png"]];

Make sure you using a valid url that contain some image and the image you are assigning to your placeholder should be there aswell.
