如何在iOS中设置表格视图单元格属性的初始值

Question

I have an image property on my table view cell. I want to populate this image to an image.

My cell looks like:

//.h
@interface GAFriendStatusTableViewCell : PFTableViewCell
@property (weak, nonatomic) IBOutlet UIImageView *friendImage;

@end

//.m
#import "GAFriendStatusTableViewCell.h"

@implementation GAFriendStatusTableViewCell

- (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier
{
    self = [super initWithStyle:style reuseIdentifier:reuseIdentifier];
    if (self) {
        self.friendImage.image = [UIImage imageNamed:@"user.png"];
    }
    return self;
}

- (void)awakeFromNib
{
    // Initialization code
}

@end

This doesn't set the image. How can I set the image for this cell within the cell class?

Answer 1

Since your image view is an IBOutlet, I'm assuming you've got your cell layout defined in a .xib or storyboard. That being the case, your initialization code should go in the awakeFromNib method. This is the method that is called when the cell is created from the nib. That's why the //Initialization code comment is there. initWithStyle:reuseIdentifier: is never called in this scenario, which is why your image is not appearing.

Answer 2

Set it in - (void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath

Otherwise if you have a Nib or Storyboard you're using then set the default in the prototype cell you are using.
