Accessing the IBOutlets's properties in the custom UITableViewCell with an IBAction - ios

Question

I'm a newbie in objective-c and iOS
I created several custom table cells with outlets in it. But I'm not sure if I use the right way.
What I want to do is to get the property of an Outlet which is inside the custom cell, by an IBAction defined in the table view controller.
I have a custom table cell called KolonNumberCell, and a UISlider in it.
I want to define an IBAction called playNumbers in the UITableViewController. The slider seems to work fine in the custom cell. I can get its value.
But I cannot figure out how to get the value of this slider when the playButton outlet is tapped.
I would be so grateful if you could give me some information or show me a way.
Thanks in advance
TableController.h
#import <UIKit/UIKit.h>
#class KolonNumberCell;
#class BankoNumberCell;
#interface TableViewController : UITableViewController{
NSArray *bundleArray;
IBOutlet KolonNumberCell *kolonCell;
IBOutlet BankoNumberCell *bankoCell;
UIButton *playButton;
}
#property (strong) IBOutlet KolonNumberCell *kolonCell;
#property (strong) IBOutlet BankoNumberCell *bankoCell;
#property (nonatomic,retain) NSArray *bundleArray;
#property (nonatomic,retain) IBOutlet UIButton *playButton;
- (void)playNumbers:(id)sender;
#end
part of TableController.m
#import "TableViewController.h"
#interface TableViewController ()
#end
#implementation TableViewController
#synthesize bundleArray,kolonCell,bankoCell,playButton;
- (void)viewDidLoad
{
[super viewDidLoad];
NSArray *bundle1 = [[[NSBundle mainBundle] loadNibNamed:#"KolonNumberCell" owner:self options:nil] objectAtIndex:0];
NSArray *bundle2 = [[[NSBundle mainBundle] loadNibNamed:#"BankoNumberCell" owner:self options:nil] objectAtIndex:0];
bundleArray = [[NSArray alloc] initWithObjects:bundle1,bundle2, nil];
}
- (void)playNumbers:(id)sender
{
NSLog(#"button");
// Get the value of the slider in KolonNumberCell... but how?
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Cell";
tableView.allowsSelection = NO;
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [bundleArray objectAtIndex:indexPath.section];
}
return cell;
}
#end
One of my customtableviewcell implementation file
#import "KolonNumberCell.h"
#implementation KolonNumberCell
#synthesize label,slider;
- (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier
{
self = [super initWithStyle:style reuseIdentifier:reuseIdentifier];
if (self) {
// Initialization code
}
return self;
}
- (void)setSelected:(BOOL)selected animated:(BOOL)animated
{
[super setSelected:selected animated:animated];
// Configure the view for the selected state
self.backgroundView = [[UIImageView alloc] initWithImage:[ [UIImage imageNamed:#"doubleRound.png"] stretchableImageWithLeftCapWidth:0.0 topCapHeight:0.0]];
}
- (IBAction)sliderChanged:(id)sender
{
[label setText:[NSString stringWithFormat:#"%i",(int)slider.value]];
}
+ (NSString *)reuseIdentifier {
return #"Cell";
}
#end

Your design is odd because your code will become really messy with more Cells.
Matt Gallagher has a nice implementation for Custom TableViews. He is using the TableViewCell as a Controller and puts all the logic related to cell in the cells class. The discussion thread on Stack Overflow:
CustomTableViewController
If you still want to do it your way:
Give your Slider a tag: slider.tag = x //Make sure that the tag is unique
In PlayNumbers:
UISlider *slider = (UISlider *)[[[bundleArray objectAtIndex:0] contentView] viewWithTag:x];
NSLog(#"%i",(int)slider.value);
Edit: thanks for correcting the syntax
