Q:

setBackgroundimage in UIButton using SDWebimage

I want to set the UIButton background image using SDWebImage.
Code :- 
[btn.imageView setImageWithURL:[NSURL URLWithString:@"image url here"]
                           placeholderImage:[UIImage imageNamed:@"placeholder"]];

Thanks

A:

There are method for this in SDWebImage :  SDWebImage / SDWebImage / UIButton+WebCache.h
Import this file in your class:
#import <SDWebImage/UIButton+WebCache.h>

Use any of this method:
- (void)sd_setBackgroundImageWithURL:(NSURL *)url forState:(UIControlState)state;
- (void)sd_setBackgroundImageWithURL:(NSURL *)url forState:(UIControlState)state placeholderImage:(UIImage *)placeholder;
- (void)sd_setBackgroundImageWithURL:(NSURL *)url forState:(UIControlState)state placeholderImage:(UIImage *)placeholder options:(SDWebImageOptions)options;
- (void)sd_setBackgroundImageWithURL:(NSURL *)url forState:(UIControlState)state completed:(SDWebImageCompletionBlock)completedBlock;
- (void)sd_setBackgroundImageWithURL:(NSURL *)url forState:(UIControlState)state placeholderImage:(UIImage *)placeholder completed:(SDWebImageCompletionBlock)completedBlock;
- (void)sd_setBackgroundImageWithURL:(NSURL *)url forState:(UIControlState)state placeholderImage:(UIImage *)placeholder options:(SDWebImageOptions)options completed:(SDWebImageCompletionBlock)completedBlock;

A:

You can directly set image to UIButton using SDWebImage
#import <SDWebImage/UIButton+WebCache.h>

 [btnProfilePic sd_setImageWithURL:[NSURL URLWithString:[NSString stringWithFormat:@"IMAGE_URL_HERE"]]] forState:UIControlStateNormal];

Or using block
[btnProfilePic sd_setImageWithURL:[NSURL URLWithString:[NSString stringWithFormat:@"IMAGE_URL_HERE"]]] forState:UIControlStateNormal placeholderImage:UIImage imageNamed:@"placeholderImage.png"] completed:
    ^(UIImage *image, NSError *error, SDImageCacheType cacheType, NSURL *imageURL) {

    }];
