What I have an iphone screen with a main UIView which has another UIView inside it with the size of 280x280 which has a tableview inside it. What I want is that when a user selects any row of that table inside that inner UIView, it pushes the user to another 280x280 UIView, so basically the main view is going to be fixed but only the inner view changes. What's the concept that can make this happen ?
Thanks in advance.
I think that user994813 wants to say this:
A UINavigationController controls the total screen. So, only pushing
and popping a 280x280 field is not possible.
The best way to achieve this would be to let a UITableViewController
be the controller of the main view. Use this as delegate and datasource
for your 280x280 tableview.
When a user selects a row, use a transition to let the tableview
disappear and the other 280x280 view appear. In other words, I fear
that you have to do this manually, although it's not very hard.
If you need a NavigationBar, create it manually in interfaceBuilder.
you need to create two 280*280 view one for your tableview and another for other(push view) and whenever you select table row you need to hidden true first view and hidden false second view(pushview).

My app contains a Table View which is scrolling and taking events properly. But after that I have to show a custom pop up to screen for that I have added a full view over the Table View. But after adding the view over Table View, Table view is still scrolling and taking events.
Please help if anyone have knowledge about that...
Thanks
The best way to achieve this is to add a blur view into your nib file first. This is better approach as the user is made aware of the current enabled object.
Once you add the blur view over the tableView you are showing, add your custom pop-over. This would maintain a clear demarcation between the two views and you would be able to achieve the functionality you want as the touches won't flow to your tableView.
Follow below steps may work:
Add overlay view on screen to show data on top of table view
make TableView Disbaled as soon as u add view on it.
Generally:
Is it OK to add a UITableView as a subview of another UITableView? Or, should I create a UIView and add each UITableView to it?
Specifically:
For a ComposeTableViewController with a typeahead, like in the iPhone's native Mail app, which approach would you recommend and why?
Note: I prefer to construct things 100% programmatically (no Interface Builder).
Subclass UITableViewController.
Then, to show the typeahead results, create and add a resultsTableView as a subview of self.tableView positioned directly underneath the the cell (of self.tableView) with the typeahead text field.
The nice thing about this approach is that resultsTableView scrolls with self.tableView automatically.
But, is it OK to add a UITableView as a subview of another UITableView?
Subclass UIViewController.
Create and add tableView (custom property) as a subview of self.view.
Create and add resultsTableView also as a subview of self.view.
The annoying thing about this approach is that I have to reposition resultsTableView manually anytime self.tableView scrolls.
I think I'd prefer approach 1, but adding a UITableView as a subview of another UITableView just seems smelly to me.
TableViews cannot have subviews. You can try adding a tableview as the view of a TableViewCell, but then you have to ask yourself how it would scroll, if you tried scrolling in the subtableview would it scroll the child tableview or the parent tableview? It is much easier to present multiple tableviews within a view. This can be done easily by setting your custom viewcontroller as the datasource of both tableviews contained within its view and then comparing the tableview pointer that is sent as a parameter of the datasource method to the two tableview pointers that are IVars of your custom view controller.
Hold stuff like this in a container. Create a container view controller which only does typeahead. This container view controller will hold your main table view controller (and its table view) and it will hold the typeahead view controller (and its view).
It will keep the logic needed for the typeahead out of your main table view and as a bonus you might end up with a reusable typeahead container which could be applied to other views.
Yes it is good to go for adding UITableView in as a cell of another UITableView.
I had one issue and posted a question
Multiple Views as subviews
And requirement was like a group of controls with list of other controls. I thought that time that it will be messy if i'm going to add UITableView as a cell of UITableView.
What i found that... Boy !! it's how iOS meant to be. There is no any lag while doing this.
Tested for below functionalities:
Scrolls like a charm
Separate delegates called for each
Reordering of both UITableView cell
Swipe and remove cell
Runtime datasource update for both UITableView and reload both at the same time.
There is no any reason not to add subview UITableView.
You can do it but it is against the principle of MVC. You will be setting the delegate of a view to another view which is wrong.
I'm trying to change the size of a tableView I have in interface builder and can't seem to. When I first started the app I could drag it around and stretch the sides but all of a sudden I can't adjust it. I tried to delete my tableView and add a new one but the same thing happened. Thanks in advance. Here's what I see when I try to change the size:
if your using a UIViewController you can drag and drop a tableView and can place in a custom position you want. but if your using a UITableViewController you cant move the tableView to your custom position. if you want to do it in UITableViewController you can do like below
if you want your tableView content should show from a point, that you want you can do this way,
[self.tableView setContentInset:UIEdgeInsetsMake(100,0,0,0)];
else if you want set your tableView to a frame in UITableViewController you do this way,
- (void) viewWillLayoutSubviews
{
[super viewWillLayoutSubviews];
self.tableView.frame = CGRectMake(0,100,320,300);
}
hope this will help you.
What kind of view controller are you using to manage your table view? Since you show "prototype cells", I'm guessing it's a UITableViewController. Those are built to fill the entire screen with a single table view (which has always annoyed me.)
Starting with iOS 6, though, you can create a "container" view in another view controler, and then drag an embed segue from your container view onto the table view controller. That does all the housekeeping to make the table view controller a child view controller of the other one, and then you can make it whatever size you want.
If you don't want to use a UITableViewController as a child of another view controller, you can use a regular view controller and wire up the data source and delegate methods yourself. However, things like static table views and prototype cells don't work then.
Hopefully this helps someone still coming across this problem. What I did was make sure the UIViewController had a UIView as its direct child, then dragged the UITableView as a child of the UIView, this allowed me to resize the UITableView.
I have a screen with a table view managed by a controller based on UITableViewController. I would now like to affix a button to the bottom of the screen so that it does not scroll along with the table view cells.
Replacing the UITableViewController with a plain UIViewController is not an option, as I want to include a UIRefreshControl. From what I have read, using a UIRefreshControl without a UITableViewController is currently not possible without resorting to any hacks / relying on undocumented behaviour.
I tried using a UIToolbar provided by the navigation controller which my table view controller is contained in, but there are two problems with that approach:
I only want the toolbar with the button to be present in the top level table view. However, I have not found an elegant way to only show the toolbar for the top level table view. I want the toolbar to animate out of the screen to the left together with the table view when I drill down.
I have not found a way to increase the height of the toolbar. Would I have to put the button in a dummy UIView?
This is approximately what I am aiming for:

Another idea is using a container view controller containing the button at the bottom and the table view controller above it as its child view controller. But that seems a lot of work for something this simple.
So what is the best way to do this? Any recommendations?
Create the UIView container view. But also create a UIViewController subclass to manage the container. Then, add your existing table view controller as a child view controller and add the table view as a subview. Now you can control all of the subviews and positions while still having automatic refresh control operation.
Just use
- (UIView *)tableView:(UITableView *)tableView viewForFooterInSection:(NSInteger)section
and return a UIView for the desired button. and
tableView:heightForFooterInSection
and return the footer height
If you aren't willing to use a container view controller, you could use a third-party pull to refresh control like https://github.com/samvermette/SVPullToRefresh instead. This has the added benefit of being backwards compatible with iOS 5, if you want to support it.
You can use a UITableViewController. Just override viewDidLoad and then resize the tableView to make room for your extra view and then add your view programmatically. Make sure to set the right resizing mask so that things look correct on different screen sizes. (Easily tested in the Simulator by trying it out on the iPhone4 and iPhone5)
Here is my app.

You can see three buttons at the top of the main screen. When you click it, the gallery will change to next. They are not the same layout style.
I created it by making three ScrollView in a big ScrollView. Code like this:
[backgroundScrollView addSubview:innerNewsScrollView];
[backgroundScrollView addSubview:innerHotScrollView];
[backgroundScrollView addSubview:innerLinkScrollView];
And when click the button, I changed the frame of the ScrollView.
Now there is a problem, when I add more than 100 Pictures(UIButton with image) to the ScrollView, It had crashed. I want to use UITableView replace ScrollView. But how can I Control more than one UITableView in a UIViewController?
Anybody can help me!
Two possibilities:
All the table view delegate methods include the table in question as one of the paramters, so it would simply be a case of checking which table is requesting data/information
You don't have to point your table views to the view controller. Your view controller could store two objects whose only purpose is to repond to table view delegate methods
Unless the tables are trivial, I think the second option is the cleanest.
Add all of your UITableViews in the UIViewController's view, set their tag properties to something you can distinct them and also set their delegates (usually self if your UIViewController implements the UITableViewDelegate protocol). Every method in the UITableViewDelegate passes UITableView reference as an argument and with the value of the tag property you can find out which table view is processed.
