//                    [_nextAction.imageView setImageWithURL:[NSURL URLWithString:postCoverImgURL]];
//                    [_nextAction setImageForState:UIControlStateNormal withURL:[NSURL URLWithString:postCoverImgURL] placeholderImage: nil];

1st is sync way, very slow
3rd works well for iPhone 4/5, but iPhone 6/7 Plus
4th works perfect, fix bug to show next button image (square in iPhone 6 plus with setImage), change the code to use setBackgroundImage instead of setImage that will give you what you want.
