Cell being populated with wrong images

[marcustoy]

Hi,

I'm currently using this code to set-up my images:

[cell.coverImage sd_setImageWithURL:[self.dataInJSONModel.Content[indexPath.row] CoverImage] placeholderImage:[UIImage imageNamed:@"imageplaceholder_general"]];

And my cells are often wrongly populated when I scroll. Guessed it is due to the cell reuse issue, where the async-downloaded images are populated to the cell that may have been re-used/disappeared. I have searched online and tried those recommendations but to no avail. Any standard method to solving this problem?

@marcustoy in your cell subclass add the prepareforreuse method and nullify the image in your imageview

Hi @mythodeia ,
I used above method, I followed almost all the tricks mentions over internet, but still problem exists. Is there any other solution for this ?

[mythodeia]

@siddhesh12 there must be a cell reuse issue somewhere hidden in your code. check the demo project to see how it works. if still you have issues please share a demo project so everyone can take a look and help

I got the solution for it. at the beginning I am calling sd_cancelImageLoadForState method. so when image gets download asynchronously it will never assign it to different cell which was previously reused. This was only used to happen when some cell do not have url from data model.

Before setting new image to imageView add:

cell.imageView.sd_currentDownloadTask?.cancel()
