How do I create a tableview with multiple rows and multiple columns? - ios

Question

I know how to create a tableview with a single column and multiple rows, but I don't know how to create a tableview with multiple rows and multiple columns.
Can anybody help me?

Answer 1

This is how i did it:
#import <Foundation/Foundation.h>
#interface MyTableCell : UITableViewCell
{
NSMutableArray *columns;
}
- (void)addColumn:(CGFloat)position;
#end
implementation:
#import "MyTableCell.h"
#define LINE_WIDTH 0.25
#implementation MyTableCell
- (id)init
{
self = [super init];
if (self) {
// Initialization code here.
}
return self;
}
- (void)addColumn:(CGFloat)position
{
[columns addObject:[NSNumber numberWithFloat:position]];
}
- (void)drawRect:(CGRect)rect
{
CGContextRef ctx = UIGraphicsGetCurrentContext();
// Use the same color and width as the default cell separator for now
CGContextSetRGBStrokeColor(ctx, 0.5, 0.5, 0.5, 1.0);
CGContextSetLineWidth(ctx, LINE_WIDTH);
for (int i = 0; i < [columns count]; i++)
{
CGFloat f = [((NSNumber*) [columns objectAtIndex:i]) floatValue];
CGContextMoveToPoint(ctx, f, 0);
CGContextAddLineToPoint(ctx, f, self.bounds.size.height);
}
CGContextStrokePath(ctx);
[super drawRect:rect];
}
#end
and the last piece, cellForRowAtIndexPath
MyTableCell *cell = (MyTableCell *)[rankingTableView dequeueReusableCellWithIdentifier:MyIdentifier];
cell = [[[MyTableCell alloc] initWithFrame:CGRectZero reuseIdentifier:MyIdentifier] autorelease];

Answer 2

-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *cellIdentifier = #"MyCell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier];
if (cell == nil) {
// load cell from nib to controller's IBOutlet
[[NSBundle mainBundle] loadNibNamed:#"MyTableCellView" owner:self options:nil];
// assign IBOutlet to cell
cell = myCell;
self.myCell = nil;
}
id modelObject = [myModel objectAtIndex:[indexPath.row]];
UILabel *label;
label = (UILabel *)[cell viewWithTag:1];
label.text = [modelObject firstField];
label = (UILabel *)[cell viewWithTag:2];
label.text = [modelObject secondField];
label = (UILabel *)[cell viewWithTag:3];
label.text = [modelObject thirdField];
return cell;
}
i think this code will help you UITableView isn't really designed for multiple columns. But you can simulate columns by creating a custom UITableCell class. Build your custom cell in Interface Builder, adding elements for each column. Give each element a tag so you can reference it in your controller.
Give your controller an outlet to load the cell from your nib:
#property(nonatomic,retain)IBOutlet UITableViewCell *myCell;
Then, in your table view delegate's cellForRowAtIndexPath method, assign those values by tag.
