Programmatically change Size of Table - ios

Question

The Storyboard: http://s7.directupload.net/images/140717/z5hwmezv.png
Hey guys,
Ive got an app that recursively triggers a the same tableview controller (lets say there are files and folders in it) until you trigger a file instead of a folder. When a file is clicked, it jumps into the GLKit View Controller.
Now I want to resize the tableView programmatically, which wont work. I already got the window size, which I'm going to use for calculation the position and size of the tableView:
CGFloat screenWidth = screenRect.size.width;
CGFloat screenHeight = screenRect.size.height;
I tried different ways to change the size like the following, which dont change anything.
mainTableView.frame = CGRectMake(0, 0, screenWidth, screenHeight);
It works If I programmatically create the mainTableView, but then my segue gets deleted and I did not found any solution to create a segue programmatically.
It would be great if you can help me to find a solution that works with a storyboard tableView.

Step 1: Add delegate UITableViewDataSource,UITableViewDelegate
#interface viewController: UIViewController<UITableViewDataSource,UITableViewDelegate>
{
UITableView *tableView;
}
Step 2:
-(void)viewDidLoad
{
tableView=[[UITableView alloc]init];
tableView.frame = CGRectMake(10,30,320,400);
tableView.dataSource=self;
tableView.delegate=self;
tableView.autoresizingMask = UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleWidth;
[tableView registerClass:[UITableViewCell class] forCellReuseIdentifier:#"Cell"];
[tableView reloadData];
[self.view addSubview:tableView];
}
Step 3: Properties for tableview
//-- For table sections
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return 1;
}
//-- For no of rows in table
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return 10;
}
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
return 1;
}
//-- Table header height if needed
- (CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section
{
return 50;
}
//-- Assign data to cells
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath] ;
if (cell == nil)
{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
cell.textLabel.text=[your_array objectAtIndex:indexPath.row]; ***(or)*** cell.textLabel.text = #"Hello";
return cell;
}
//-- Operation when touch cells
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
// Your custom operation
}

Looking at your pic makes me think your CustomerListVC is a UITableView subclass which means the tableview is the root view and if you are using a UINavigationController based flow then you can't resize the root view readily.
What you can do is place the UITableView in a container and manipulate its constraints from the controller.
first change
class CustomerListVC : UITableViewController
to
class CustomerListVC : UIViewController
next throw away the Customer List instance in Interface Builder and drag in a new UIViewController instance instead. Xcode doesn't like you changing the base class of its stock objects.
make the new UIViewController instance a CustomerListVC type FileOwner and drag a UITableView into the content view.
Set edge constraints and add outlets to the constraints in your view controller.
From there play with the table as you see fit. e.g
-(void)squishAtBottomLeftAnimated:(BOOL)animate {
CGFloat animateTime = animate? 0.5:0;
[UIView animateWithDuration:animateTime animations:^{
self.topEdgeConstraint.constant = 400;
self.bottomEdgeConstraint.constant = 5;
self.leadingEdgeConstraint.constant = 5;
self.trailingEdgeConstraint.constant = 200;
[self.view layoutIfNeeded];
}];
}
