I was wandering if its possible to have more than one uiTableView in one ViewController.
For example:
tableView1 and tableView2 in one view controller.
Initial start up of view controller, tableView2 should be disabled and not visible.
tableView1 should show the data associated with it.
When user selects a row from tableView1... it should then show the data corresponding to the selected row in tableView2.
tableView1 should still be enabled, and if user selects another row, the contents of tableView2 should also change respectively.
Thanks for any help or guidance given. :)
Of course you can do this. This is 5 minutes in storyboard.
You should choose UIViewController (not UITableViewController!)
And create something like this:
Then you should create object references with a ctrl key.
You have to remember that you have to set delegate and dataSource in both tableViews to your ViewController:
And in yout second table view set initialView to hidden.
Then in your code in method - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath you should in first line call:
[self.mySecondTableView setHidden:NO]
and do all your stuff later. That's it.
EDIT:
Now i realize that you have set topic to "multiple" tableViews. This solution is messy enough for two TableViews. I suggest you to use container, and then all tableView will have own ViewController.
You can set different tags and outlets for this two TableView.
Then in
-(void)ViewDidLoad
self.yourSecondTableView.hidden = YES;
to hide second tableView
and when delegates methods was called
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
or
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
you can ask for tag like
if (tableView.tag == yourSecondTableViewTag)
return something

I haven't developed any iOS apps in a while. I am fine with both swift and Objective-C but what I find different is adding a UITableView to ViewController. Before, I used to add a UITableView to ViewController, add the required datasource methods and the typical UITableViewCell object, and return the cell in cellForRowAtIndexPath:, which would display empty cells depending on the number of rows I return. Now, I did everything the same, but the UITableView is empty and when I scroll I see the lines but not my cell.textlabel.text value, which I set. It seems now I am supposed to add UITableViewCell to the UITableView and remove the
#pragma-mark TableView Datasource
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return [_formTitles count];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewCell *cell =[tableView dequeueReusableCellWithIdentifier:#"cell"];
if(cell==NULL)
{
cell=[[UITableViewCell alloc]initWithStyle:UITableViewCellStyleValue1 reuseIdentifier:#"cell"];
}
cell.textLabel.text=[_formTitles objectAtIndex:indexPath.row];
cell.detailTextLabel.text=#"Kaushik";
return cell;
}
I can't find a simple post online regarding the same.
Can someone post what are the changes in the new iOS 9 in a simple manner?
Thank you
Right..For those of you who are still prefer to add a tableview to a viewcontroller.Here are the steps
In the ViewController drag and drop the tableview.Now instead of the lines which you see in the old Xcode.This time you would see a blank table view with the text " Table View prototype content" in the middle.
We usually create a tableviewcell only we doing anything different like adding more labels or image etc but hereafter it is required to add a tableviewcell in the tableview.Drag and drop a tableview onto the tableview.It will display as protype cells.One can select type of cell here itself as basic,value 1,value 2 or subtitle.Also NEED TO SET THE REUSE IDENTIFIER IN THE STORYBOARD UTILITIES PANEL ON YOUR RIGHT. At the end, you can select the tableview and add the missing constraints.
Implement the typical required datasource methods in your viewcontroller class.
(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return 5;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewCell *cell =[tableView dequeueReusableCellWithIdentifier:#"cell"];
cell.textLabel.text=#"text";
cell.detailTextLabel.text=#"DetailedText";
return cell;
}
The change here is that we dont require the usual if(cell==nil)
{..}
piece of code since we added the prototype cells to the storyboard.
Don;t forget to connect the delegate and datasource of the tableview to the viewcontroller.
This should display the tableview in your viewcontroller but i am getting a space on top of the tableview which i don't know why.Anyway this is how you add a tableview to a view controller using Objective-C language in iOS 9.3.
FYI: Guys if i've missed anything, please mention it in the comments
Thank you
Put tableView to view controller and link it to viewcontroller.
link delegate and datasource of tableview to viewcontroller.
in
viewcontroller.h
#interface ViewController :<UITableViewDelegate, UITableViewDataSource>
in viewWillAppear put
tblService.delegate=self;
tblService.dataSource=self;
and your array elements.
5.Impliment your tableview delegate method and datasource method .
6.be sure you cell identifier equal the one put on storyboard.
this link will help you more to implement your first app and this video.
Im trying to have 2 table views on the same view. They both are within the same UIViewController which implementes the UITableViewDelegate and Datasource. one of the tableviews is static and the other is dynamic. The dynamic table view is loading just fine using the methods from its datasource, but the static one is showing up blank. Normally I erase the datasource methods from the controller so the static TableView doesn't override what's already done on the storyboard, but now I can't because those methods are being used by the dynamic TableView.
How can I have both of then under the same controller?
As Putz says, you can set up your view controller to manage 2 table views by setting up your data source and delegate methods to check the table view that's passed in.
However, I don't think you can use static table views with anything but a UITableViewController, and a table view controller only knows how to manage a single table view.
The trick is to add 2 container views to your view controller that will contain 2 table views, and embed a different UITableViewController into each container view. Then each table view is managed by it's own table view controller. I have a project on github that does exactly this: https://github.com/DuncanMC/test
I've set up protocols that the parent view controller and the 2 table view controllers use to communicate, although you don't have to do that if your needs are simpler.
Here is the easiest option, that let's you keep a single VC for your delegate/datasource :
Set both tableviews delegate and datasource to your UIViewController.
Ctrl-drag from one of the static cells to your .h file, and create an IBOutlet collection ( called here staticCellsCollection). Add each static cell to this collection, careful with the order, it will be important.
Implement cellForRowAtIndexPath: this way :
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
if (tableView == _dynamicTableView) {
// Do your dynamic thing
}
else if (tableView == _staticTableView) {
// Return the static cells one by one
// Here the static TV has only one section, and all cells are in staticCellsCollection
return staticCellsCollection[indexPath.row];
}
}
You also need to adapt numberOfRowsInSection and numberOfSectionInTableView but this is pretty basic (check which table is asking, and return appropriate values, for example staticCellsCollection.count for the number of rows of the static TV).
You may need to adapt this, for example if you want multiple sections in your static TableView, you should create an IBOutletCollection for each section, and handle the number of rows/sections accordingly, and return the correct cells. Anyway, this is pretty straightforward to implement once you get the idea.
You can have two tableView's use the same delegate functions. It's not amazingly pretty, but you can:
- (UITableViewCell *)tableView:(UITableView *)inTableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
if(inTableView == tableView1)
{
...
}
else if
...
}
Put that type of logic into every tableView delegate function.
I am using several static cells in a tableviewcontroller.
Each cell has a detail accessory. What method can I use in the tableviewcontroller to perform logic based on the click of a detail accessory?
You just need to make your tableView delegate implement the following method
- (void)tableView:(UITableView *)tableView accessoryButtonTappedForRowWithIndexPath:(NSIndexPath *)indexPath
I guess you can just drag from the cell to the view and it gives you a cell and accessory object.
First, why: I have a class called AKTableViewController that inherits from UITableViewController and most of my View Controllers inherit from that.
I'm tryingto make a Category to add a banner on the bottom of each screen, not scrolling with the content, so I add my banner as the self.tableView.tableFooterView and than I position it on scrollViewDidScroll:.
My problem is, when the data is reloaded the banner is sent back to the right position and I don't have any callback to properly position it.
So: How to be notified when an UITableViewController has reloaded its data?
Use the delegate method for UITableView:
-(void) tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath
{
if([indexPath row] == ((NSIndexPath*)[[tableView indexPathsForVisibleRows] lastObject]).row){
//Finished loading visible part of your table
}
}
The way you're doing this seems convoluted. It sounds like you should be adding the banner as a separate view, not as a footer of the table view.
This is what I am trying to do...but not sure how to do :
I have a tableview consisting of multiple rows in multiple sections. When I scroll the table going from 1 section to another, I want to do some other action - I want to have an action handler for this. But, I am not sure how to do it.
Cany anyone please help me out ? Thanks.
You can set the tableview delegate as the controller and implement this delegate function
- (void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath
This function will get called before a cell is going to be displayed. You can use the indexpath to check if it is going to be first item in a section.
Hope this helps.
