Help,
I have been try to populate a tableview with a list of object properties. I have an object class, object controller class and my ui. I could just use a simple list and populate my table but in other parts of my program I will need objects with multiple properties to fill in other tableviews.
Here is my code, I figure its a line or 2 that needs to be changed.
============ Object class ===============
================ Object controller class ==================
========================== UI screen with table view ====================
Thanks an help will be appreciated.

============ Object class ===============
Code:
#import <Foundation/Foundation.h>
@interface Category : NSObject
{
NSString *name;
}
@property (copy, nonatomic) NSString *name;
-(void) print;
@end
#import "Category.h"
@implementation Category
@synthesize name;
-(void) setName: (NSString *) theCategory
{
name = [[NSString alloc] initWithString: theCategory];
}
-(void) print
{
NSLog(@"Category name: %-31s",[name UTF8String]);
}
@end================ Object controller class ==================
Code:
#import <Foundation/Foundation.h>
#import "Category.h"
@interface Categories : NSObject
{
NSString *categoryName;
NSMutableArray *categoryList;
NSMutableArray *testList;
}
-(id) initWithName: (NSString *) name;
-(void) addCategory: (Category *) theCategory;
-(int) enteries;
-(void) list;
-(NSMutableArray *) getList;
-(void) testList;
//-(void) dealloc;
@end
#import "Categories.h"
@implementation Categories;
- (id) initWithName: (NSString *) name
{
self = [super init];
if (self)
{
categoryName = [[NSString alloc ] initWithName: name ];
categoryList = [[NSMutableArray alloc] init ];
}
return self;
}
-(void) addCategory:(Category *)theCategory
{
[categoryList addObject: theCategory];
}
-(int) enteries
{
return [categoryList count];
}
-(void) list
{
NSLog(@"======= Contents of: %@ =======", categoryName);
for (Category *theCategory in categoryList)
NSLog (@"%-20s", [theCategory.name UTF8String]);
NSLog (@"=======================================");
}
-(NSMutableArray *) getList
{
if([categoryList count] == 0)
{
[self testList ];
for (int i =0; i < [testList count]; i++)
{
Category *cat = [[Category alloc] init];
[cat setName: [testList objectAtIndex: i]];
[categoryList addObject: cat];
}
}
return categoryList;
}
-(void) testList
{
testList = [[NSMutableArray alloc] init];
[testList addObject: @"item1"];
[testList addObject: @"item2"];
[testList addObject: @"item3"];
[testList addObject: @"item4"];
[testList addObject: @"item5"];
}
@end========================== UI screen with table view ====================
Code:
#import <UIKit/UIKit.h>
@interface FirstViewController : UIViewController<UITableViewDataSource, UITableViewDelegate>
{
NSMutableArray *categoryList;
}
@property (nonatomic, retain) NSMutableArray * catList;
@end
#pragma - Tableview Methods
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return catList.count;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
//Step 1: Check to see if cell row can be reused
UITableViewCell * cell = [tableView dequeueReusableCellWithIdentifier:@"cell"];
//Step 2: If there are no cells to reuse create a new one
if (cell == nil)
{
cell = [[UITableViewCell alloc] initWithStyle: UITableViewCellStyleDefault reuseIdentifier:@"cell"];
}
//Add a detail view accessory
cell.accessoryType = UITableViewCellAccessoryDetailDisclosureButton;
//Step 3: Set text
// cell.textLabel.text = ([categoryList valueForKey:@"name"]);
[self getList];
cell.textLabel.text = [categoryList valueForKey:@"name"];
// cell.textLabel.text = [categoryList objectAtIndex:indexPath.row];
cell.textLabel.font = [UIFont systemFontOfSize:17];
cell.textLabel.numberOfLines = 0;
cell.textLabel.lineBreakMode = UILineBreakModeWordWrap;
//Step 4: return index row
return cell;
}
-(CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
CGSize size = [[catList objectAtIndex:indexPath.row]
sizeWithFont:[UIFont systemFontOfSize:17]
constrainedToSize:CGSizeMake(200,CGFLOAT_MAX)];
return size.height + 10;
}
-(void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath
{
cell.backgroundColor = (indexPath.row%2)?[UIColor lightGrayColor]:[UIColor clearColor];
