Tableview is not visible on UIViewController - ios

Question

UITableView is not visible on the UIViewController Class.
On Storyboard added a new UIViewController set to related SlideViewcontroller class to it, Add a new UITableView (tbl_Slide), set the datasource and delegate to UIViewController in storyboard for the added UITableView.
And also included the related datasource and delegate methods to the UIViewController class.
- (void)viewDidLoad {
[super viewDidLoad];
self.tbl_SlideMenu = [[UITableView alloc]
initWithFrame:CGRectMake(0, 80, self.view.frame.size.width, self.view.frame.size.height) style:UITableViewStylePlain];
self.tbl_SlideMenu.tableFooterView = [[UIView alloc] initWithFrame:CGRectZero];
self.tbl_SlideMenu.autoresizingMask = UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleWidth;
self.tbl_SlideMenu.separatorColor = [UIColor lightGrayColor];
self.tbl_SlideMenu.dataSource=self;
self.tbl_SlideMenu.delegate=self;
[self.view addSubview:self.tbl_SlideMenu];
}
Since added the UITableView to the UIViewController for UIView, need not to induced above two lines of code
self.tbl_SlideMenu = [[UITableView alloc]
initWithFrame:CGRectMake(0, 80, self.view.frame.size.width,self.view.frame.size.height) style:UITableViewStylePlain];
[self.view addSubview:self.tbl_SlideMenu];
Once I included the allocation and added to subview its showing the data with tableview.
Once I removed allocation and frame added to subview is not visible.
So what is need of storyboard where I added UITableView to UIViewController for UIView (view default.) once Component added to storyboard and framed need not to allocate and frame in code.
Advance Thanks
Hope for best posible answers

Answer 1

If u added the tableview in storyboard there is no need to initialise the view components in the code in this case u don't need below lines as u mentioned
self.tbl_SlideMenu = [[UITableView alloc]
initWithFrame:CGRectMake(0, 80, self.view.frame.size.width,self.view.frame.size.height) style:UITableViewStylePlain];
however u need to create a outlet for your tableview to access the tableview in code that means as soon as view is loaded all your view components are initialised in your case tableview is initialised and u can ready to use it and also u don't need below lines of code if u set datasource and delegate in storyboard
self.tbl_SlideMenu.dataSource=self;
self.tbl_SlideMenu.delegate=self;
since u configured your tableview datasource and delegate and also added tableview to view controller's view there is no need of below line also
[self.view addSubview:self.tbl_SlideMenu];
and second way is as u mentioned creating the view in pure code, in this case u have to do all things by your self from initialising to adding the view component to controller's view as u mentioned like below
self.tbl_SlideMenu = [[UITableView alloc]
initWithFrame:CGRectMake(0, 80, self.view.frame.size.width, self.view.frame.size.height) style:UITableViewStylePlain]; //creating the tableview
self.tbl_SlideMenu.tableFooterView = [[UIView alloc] initWithFrame:CGRectZero];
self.tbl_SlideMenu.autoresizingMask = UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleWidth; //configuring the view
self.tbl_SlideMenu.separatorColor = [UIColor lightGrayColor];
self.tbl_SlideMenu.dataSource=self; //setting the datasource and delegate
self.tbl_SlideMenu.delegate=self;
[self.view addSubview:self.tbl_SlideMenu]; //adding it to tableview
hope u get this
Edit
it is working fine for me, i crossed checked it with some dummy values, for example as i mentioned , dragged and dropped a tableview, set its datasource and delegate to View Controller in storyboard and connected a outlet in ViewController.h file, like below,
#import <UIKit/UIKit.h>
#interface ViewController : UIViewController <UITableViewDataSource,UITableViewDelegate>
#property (weak, nonatomic) IBOutlet UITableView *tbl_SlideMenu;
#end
and in ViewController.m file
#import "ViewController.h"
#interface ViewController ()
#end
#implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
self.tbl_SlideMenu.autoresizingMask = UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleWidth;
self.tbl_SlideMenu.separatorColor = [UIColor lightGrayColor];
}
- (void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return 5;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:#"CELL"];
if(cell == nil)
{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:#"CELL"];
}
cell.textLabel.text = #"Hello";
return cell;
}
#end
and i got output showing the tableview with 5 "Hello" on each row
