So i have a static tableview with 4 rows, i'm connecting them to different viewcontrollers without using any code instead i'm simply dragging the cell and setting up the segue.
The issue i'm having is that when this segue is performed a navigation controller is automatically generated and embed at the top so i get the following result below.
How could i edit the text and the icon? I want to remove the settings text and use my own custom icon.
It's also worth noting that i have embed other navigation controllers throughout my app. So i'd like to target this view specifically rather than all of my views.
I suspect the accepted answer on this question may help: how to replace/customize back button image in storyboard navigationcontroller
You'll need to do it in your prepareForSegue I believe.

I use the same DataTemplate to populate some of the views inside my CarouselView: a XAML file with a ContentView. I assign a custom class list to ItemsSource of the carouselview AND use bindings inside the template layout fields to fill them with the properties of my custom class. Everything is working fine. Here comes the wierd part: Let's say there's a button in the template and when you click it on the screen, a Label with "Well Done" text is added to the current Stacklayout of the shown carouselview. This is done by the codebehind of my template XAML. This is ok, too, but I expect this "Well Done" to disappear after I swipe back and forth enough. Because it's not part of the template. It does not disappear, instead I see it on other carousels once in every 4 swipes and it is replaced, I mean it appears on different carousels if I swipe back and forth. To make it disappear completely I have to swipe away from the views that share the same DataTemplate. I cannot understand the mechanics behind this behaviour. I can create another field inside the template to put the "Well Done" text there and show it when the time comes, I know. But I want to understand the mechanics. Thank you.
Asking the right question about a problem is the key to any solution..
After the realization that I've mentioned at the Update comment, I've searched for DataTemplate Caching and found this issue post on Xamarin.Forms Github: https://github.com/xamarin/Xamarin.Forms/issues/9200
There you can find an explanation to how CollectionView was designed and understand the mechanics behind the behaviour. No bug. It's by design.
Is there a way to open a second Fragment Page? (ie. open multiple fragment pages at the same time)
I have a database setup and when users click a button a Fragment Page pops up so they can edit the fields. I would like to try and have a sub-menu appear for comments (so they don't have to scroll all the way to the bottom of the screen).
Something like the Menu in the Material Gallery Sample would be great.
Note:
I am currently using app.showDialog(app.pageFragments.Menu); to open the Page Fragments.
Having both Fragments open side by side would be a usable options as well.
Thanks!
Here is an example diagram.
Sorry for the late reply. I'll put this as an answer because I think it will get you what you need. You could implement this if you put the page fragments directly into your page, and toggled their visible property to show/hide them.
The biggest trick here is how does the first page fragment tell the second to open? That ends up being simple, just add a custom boolean property to the first fragment. Then in the base page (which contains the two fragments) bind the visible property of the second fragment to the custom property of the first fragment. Then in the first fragment, you can set that property to "true" when you want the second fragment to show, and "false" when you want it to hide.
Can anyone tell me how I might add buttons, or other components, to a title/tool bar without using the items array? For months I've been struggling to find a way to make the bar on all my views contain the same user buttons and icons.
It's a struggle mostly on List item detail views where only a back button shows. I want the back button but also own buttons on the same bar. This is so my app has a uniform look and accessible functionality across the entire build.
Toolbar and TitleBar extend Ext.Container.
In Sencha Touch containers always store their components inside the items array.
If you want to have a toolbar that always look the same just create your own by extending Ext.Toolbar. Use the initialize method of such extended Toolbar to add the buttons/icons.
To use it with a list you can create a wrapping container, which contains the extended toolbar and the list.
Short Version:
"How do you get a simple UITable drill down UINavigationController-styled non-full-screen modal dialog on the iPad?"
Long version:
I have a very specific set of requirements that I can't seem to get working...
I have a functioning iPad program that that needs to pop up a non-full-screen modal view. This modal needs to have a navigation controller and a simple drill-down table that displays a detailed view that I can have edit some values related to the selected item in the table.
Of course I am looking to have the regular "Back" and "Delete" buttons in the Navigation Bar.
I can handle the detailed view, what I am having issues with:
Non-full-screen popup (mine is
always full screen no matter what I
try).
The Navigation controller will not display the Table View I tell it to and the navigation bar does not even have the title I assigned to it in IB.
I can't seem to get any of this working. If anyone has a step by step example of how to do this, that would be great,
~Eric
P.S. I am not afraid of doing this 100% programmatically, but all the examples I have been trying to follow (and failing at extending to my problem) use IB.
As for the fullscreen issue, you need to set modalPresentationStyle to UIModalPresentationFormSheet or UIModalPresentationPageSheet on the controller you want to present modally. I'm not sure of a way to do this through IB.
As for your navigation controller/table view, I think more information is needed to provide an answer.
I am working on a navigation based application. I am using navigation controller for this purpose. I want to use tab bar on one of the screens and i am not able to find any way of doing this. As far as i have read, it is not possible to add tab bar controller when you are using navigation controller. Is it right? One solution was to manually add a tab bar on the screen and write its delegate class but in this solution, I will lose "More" button functionality because this thing is handled by tab bar controller itself. Does anyone has any solution to my problem? Please help!!!
You can add a UINavigationController to each of the UITabBarController's tab views but not the other way around.
According to Apple's documentation you cannot push a UITabBarController on top of the UINavigationController. I'm not sure if that is a technical limitation or if they will reject your application when you submit. Either way you shouldn't try to do this.
