SDWebImage in a simple test app crashes with NSInvalidArgumentException - ios

Question

In Xcode 5.0.2
I create a blank single view app for iPhone,
then add a "male.png" image to the project,
drag a UIImageView to the storyboard
and finally add the following code to the viewDidLoad:
_imageView.image = [UIImage imageNamed:#"male.png"];
This works well:
Then I add the files from SDWebImage project and change the ViewController.m to:
#import "ViewController.h"
#import <SDWebImage/UIImageView+WebCache.h>
static NSString* const kAvatar = #"http://gravatar.com/avatar/55b3816622d935e50098bb44c17663bc.png";
#interface ViewController ()
#end
#implementation ViewController
- (void)viewDidLoad
{
[super viewDidLoad];
[_imageView setImageWithURL:[NSURL URLWithString:kAvatar]
placeholderImage:[UIImage imageNamed:#"male.png"]];
}
#end
Unfortunately, this results in app crash with the error message:
2014-01-11 19:21:57.731 sdImage[2563:70b] -[UIImageView setImageWithURL:placeholderImage:]: unrecognized selector sent to instance 0x8a5aa80

Why does it happen please? While adding the framework files I have set the checkbox to copy the files.
UPDATE:
I have also tried the following:
git submodule add https://github.com/rs/SDWebImage.git
then built that project (SDWebImage.xcodeproj) and closed it.
Then I have reopened in Xcode my project (sdImage.xcodeproj) and dragged the SDWebImage.xcodeproj file into it.
After that I have tried to add a Target Dependency, but it doesn't show anything named "SDWebImage" there:
Here the full sized screenshot.
And I can not add an "SDWebImage.framework" under Link Binary With Libraries, because nothing named "SDWebImage" is there.

Answer 1

Why don't you just include the SDWebImage source files in your main project? This is how I incorporated SDWebImage, and the SDWebImage docs themselves state: "There are two ways to use this in your project: copy all the files into your project, or import the project as a static library." If you do this there is no need to open the SDWebImage project, compile the framework, link the framework with your project, etc.

Answer 2

I've got the project by using CocoaPods with the following Podfile:
platform :ios, '5.0'
pod 'SDWebImage'
and then running pod install and opening sdImage.xcworkspace in Xcode.
I'm still interested in how to use SDWebImage in a project - without using CocoaPods...
