Delegate TabBar from custom UITableViewCell - ios

Question

I have created a custom cell with a specific list of properties, including UITabBar. This cell has its specific Class called RecomandationCell, where I have declared these properties.
I use this custom cell to created multiple cells with different objects, also I want to know when I click an item of this tab bar in a specific row call its method that comes from Delegation of <UITabBarControllerDelegate> which is
- (void)tabBar:(UITabBar *)tabBar didSelectItem:(UITabBarItem *)item
{
if (item.tag==0)
{
NSLog(#"Likes Clicked");
}
if (item.tag==1)
{
NSLog(#"Comments Clicked");
}
if (item.tag==2)
{
NSLog(#"Shares Clicked");
}
if (item.tag==3)
{
NSLog(#"Add Clicked");
}
if (item.tag==4)
{
NSLog(#"Ratings Clicked");
}
}
The problem is that this method won't be fired because I don't know where to delegate it, and even If I delegate it I don't know which tab bar at a specific index was clicked.

oky u can do like this
in CustomCell.h
#interface CustomTabedCell : UITableViewCell<UITabBarDelegate>//confirms to delegate
in CustomCell.m file
#import "CustomTabedCell.h"
#implementation CustomTabedCell
- (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier
{
self = [super initWithStyle:style reuseIdentifier:reuseIdentifier];
if (self) {
// Initialization code
UITabBarItem *firstItem = [[UITabBarItem alloc]initWithTitle:#"1" image:nil tag:10];//you can specify image hear i put nil
UITabBarItem *secondItem = [[UITabBarItem alloc]initWithTitle:#"2" image:nil tag:11]; // ... give tag number
UITabBar *tabBar = [[UITabBar alloc]initWithFrame:CGRectMake(0, 0, 320, 70)]; //leave this if u are added in xib
tabBar.delegate = self; //delegate to custom cell itself
tabBar.tag = 100;//leave
tabBar.items = [NSArray arrayWithObjects:firstItem,secondItem, nil];//add to tab bar
[self.contentView addSubview:tabBar];
}
return self;
}
//in custom cell u are getting the delegate call's
- (void)tabBar:(UITabBar *)tabBar didSelectItem:(UITabBarItem *)item
{
if (item.tag==10) //compare using tages as u added to tabed bar
{
NSLog(#"Likes Clicked");
}
if (item.tag==11)
{
NSLog(#"Comments Clicked");
}
if (item.tag==12)
{
NSLog(#"Shares Clicked");
}
if (item.tag==13)
{
NSLog(#"Add Clicked");
}
if (item.tag==14)
{
NSLog(#"Ratings Clicked");
}
}
after this u can call custom delegate method to controller for further processing

First: You have specified UITabBarControllerDelegate in the interface for the cell, when you probably wanted to specify UITabBarDelegate.
Second: You set the delegate when you create the tabbar. Your provided code does not show this. You need to init the tabbar somewhere, and then you set a delegate on it.
Third: The place to setup something specific in a cell would be in the cellForRowAtIndexPath in the tableviewcontroller.
Fourth: To get the index of the tapped tabbar-item, you can do that in the didSelectItem method:
NSUInteger indexOfTab = [[tabBar items] indexOfObject:item];
NSLog(#"Tab index = %u", indexOfTab);
