Passing a UIImage from one view controller to a UI

问题:

I am using a UITable to show images (Like a feed in instagram) I have the image saved in the viewcontroller I am taking the picture, but I need a way to pass the UIImage i have created to the UITableViewCell. What would be the best way to accomplish this.

回答1:

You need to subclass UITableViewCell and give it a public property like

@property (nonatomic, strong) UIImage *thumbnailImage;

then in your uitableviewcells implementation file create and add a UIImageView however you want.

- (void)setThumbnailImage:(UIImage *)thumbnailImage
{
   _thumbnailImage = thumbnailImage;
   self.imageView.image = _thumbnailImage;
}

in your cellForRowAtIndexPath method, do something like

cell.thumbnailImage = [UIImage imageNamed:"YourImage.png"];

This is just one of many ways to do this.
