help populating a uitableview

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 ===============

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];
}

Thanks an help will be appreciated.

 

ok, I added this code to my category interface

Code:

- (id) initWithName:(NSString*)name;

and this code to my category implementation

Code:

 - (id) initWithName:(NSString*)name {
self.name = name;
}

and I put this line in my category implementation where i create my array with category objects

Code:

Category *cat1 = [[Category alloc] initWithName:@"I LIEK TURTLES"];

so when I add this line to my interface file to populate the tableview it does not recognize arrayWithCategoryobjects

Code:

Category *category = [arrayWithCategoryobjects objectAtIndex:indexpath.row];

i know i'm missing something but don't know what.
if you want i will repost my code pieces, I have seen arrayWith... before, but don't remember where

thxs for your help so far

 

I got it all working. I followed and understand what you posted. I brain farted the the list part last post. This will be a big help going forward in showing me my mistakes, like forgetting my constructor in my object class as well as using the super init (much like java).

Although it is a very basic program it is my first objective c/iphone app.

Thanks for all your assistance and I will change self.name to _name.
