How to create common UITableView for all view controllers?

Question

Does anyone have an idea about how to use a single UITableView in multiple ViewControllers?

I need to create a common UITableView for all my view controllers and use it through out the application.

Any help is appreciated.

Answer 1

Use ContainerView, you can drag ContainerView into your ViewControllers in a storyboard, adjust the size according what you need. You use the ContainerView in all that ViewController that need the TableView.

Attached is a screen shot of one of my app that is using ContainerView that contains a TableView inside the ViewController. I am using the same thing in 2 different ViewControllers.

Answer 2

You can use singleton. Here is an example:

CommonTableView.h file:

#import <Foundation/Foundation.h>

@interface CommonTableView : UITableView <UITableViewDelegate>

+ (CommonTableView *)sharedInstance;

@end

CommonTableView.m file:

#import “CommonTableView.h”

CommonTableView *sharedInstance = nil;

@implementation CommonTableView

+ (CommonTableView *)sharedInstance
{    
    static dispatch_once_t pred;

    dispatch_once(&pred, ^{
        sharedInstance = [[super allocWithZone:nil] init];
    });

    return sharedInstance;
}

- (id)init
{
    self = [super init];
    if (self) {
        self.delegate = self;
        //customize your table view
    }

    return self;
}

#pargma mark - UITableView delegate
//…

@end

Then you can access your tableView with [CommonTableView sharedInstance] in the UIViewControllers that you want.
