customising UITableViewCell with picture objective-C - objective-c

Question

I want to have custom cell in UITableView, I create my UIView via storyboard and I linked them to the code
I don't know why my picture does not appear
Would you please check my code ?
customise code .h
: UITableViewCell
#property (strong, nonatomic) IBOutlet UIImageView *weekImg;
#end
customise code .m
#synthesize weekImg;
- (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier
{
self = [super initWithStyle:style reuseIdentifier:reuseIdentifier];
if (self) {
// Initialization code
weekImg=[[UIImageView alloc]initWithImage:[UIImage imageNamed:#"red.png"]];
}
return self;
}
My method: cellForRowAtIndexPath:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
WeekTableViewCell *cell = (WeekTableViewCell*)[tableView dequeueReusableCellWithIdentifier:#"WeekTableViewCell"];
NSString *key = [[self sectionKeys] objectAtIndex:[indexPath section]];
NSArray *contents = [[self sectionContents] objectForKey:key];
NSString *contentForThisRow = [contents objectAtIndex:[indexPath row]];
[[cell textLabel] setText:contentForThisRow];
return cell;
}

Answer 1

I think this is because your code is just looking for previosuly created cells. at th start no cells will be created and wont be able to retrieve any this way.
WeekTableViewCell *cell = (WeekTableViewCell*)[tableView dequeueReusableCellWithIdentifier:#"WeekTableViewCell"];
if (cell == nil){
NSArray *topLevelObjects = [[NSBundle mainBundle] loadNibNamed:#"WeekTableViewCell" owner:nil options:nil];
for(id currentObject in topLevelObjects)
{
if([currentObject isKindOfClass:[WeekTableViewCell class]])
{
cell = (WeekTableViewCell *)currentObject;
break;
}
}
}
cell.selectionStyle = UITableViewCellSelectionStyleNone;
NSString *key = [[self sectionKeys] objectAtIndex:[indexPath section]];
NSArray *contents = [[self sectionContents] objectForKey:key];
NSString *contentForThisRow = [contents objectAtIndex:[indexPath row]];
[[cell textLabel] setText:contentForThisRow];
return cell;
this way create a new cell if there isnt a cell to re use

-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
cell.imageView.layer.cornerRadius=10.0f;
[cell.imageView.layer setMasksToBounds:YES];
cell.textLabel.text=[NSMUtableArray objectAtIndex:indexPath.row];
switch (indexPath.row)
{
case 0:
cell.imageView.image=[UIImage imageNamed:#"img1.png"];
break;
case 1:
cell.imageView.image=[UIImage imageNamed:#"img2.png"];
break;
case 2:
cell.imageView.image=[UIImage imageNamed:#"img3.png"];
break;
case 3:
cell.imageView.image=[UIImage imageNamed:#"img4.png"];
break;
default:
break;
}
}
cell.imageView.layer.cornerRadius=10.0f;
[cell.imageView.layer setMasksToBounds:YES];, it is used by QuartzCore.
The output of the cell like this, we can adjust the image size.
