This problem is simple, but crucial and urgent. Here's what needs to be done:
load 66px x 66px images into the table cells in the MainViewController table. each TableCell has a unique image.
But how?
Would we use cell.image?...
cell.image = [UIImage imageNamed:@"image.png"];
If so, where?
Is an if/else statement required? Help?
Here's the project code, hosted on Google Code, for easy and quick reference... http://www.google.com/codesearch/p?hl=en#Fcn2OtVUXnY/trunk/apple-sample-code/NavBar/NavBar/MyCustomCell.m&q=MyCustomCell%20lang:objectivec
To load each cell's labels, MainViewController uses an NSDictionary and NSLocalizedString like so...
//cell one
menuList addObject:[NSDictionary dictionaryWithObjectsAndKeys:
NSLocalizedString(@"PageOneTitle", @""), kTitleKey,
NSLocalizedString(@"PageOneExplain", @""), kExplainKey, nil]];
//cell two
menuList addObject:[NSDictionary dictionaryWithObjectsAndKeys:
NSLocalizedString(@"PageOneTitle", @""), kTitleKey,
NSLocalizedString(@"PageOneExplain", @""), kExplainKey, nil]];
...
// this is where MainViewController loads the cell content
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
MyCustomCell *cell = (MyCustomCell*)[tableView dequeueReusableCellWithIdentifier:kCellIdentifier];
if (cell == nil)
{
cell = [[[MyCustomCell alloc] initWithFrame:CGRectZero reuseIdentifier:kCellIdentifier] autorelease];
}
...
// MyCustomCell.m adds the subviews
- (id)initWithFrame:(CGRect)aRect reuseIdentifier:(NSString *)identifier
{
self = [super initWithFrame:aRect reuseIdentifier:identifier];
if (self)
{
// you can do this here specifically or at the table level for all cells
self.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
// Create label views to contain the various pieces of text that make up the cell.
// Add these as subviews.
nameLabel = [[UILabel alloc] initWithFrame:CGRectZero]; // layoutSubViews will decide the final frame
nameLabel.backgroundColor = [UIColor clearColor];
nameLabel.opaque = NO;
nameLabel.textColor = [UIColor blackColor];
nameLabel.highlightedTextColor = [UIColor whiteColor];
nameLabel.font = [UIFont boldSystemFontOfSize:18];
[self.contentView addSubview:nameLabel];
explainLabel = [[UILabel alloc] initWithFrame:CGRectZero]; // layoutSubViews will decide the final frame
explainLabel.backgroundColor = [UIColor clearColor];
explainLabel.opaque = NO;
explainLabel.textColor = [UIColor grayColor];
explainLabel.highlightedTextColor = [UIColor whiteColor];
explainLabel.font = [UIFont systemFontOfSize:14];
[self.contentView addSubview:explainLabel];
//added to mark where the thumbnail image should go
imageView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 66, 66)];
[self.contentView addSubview:imageView];
}
return self;
}
HELP?
