I'm trying to make a custom tabgroup in appcelerator in which one (or two) of the tabs is bigger than the rest. I have attached an image of what I'm trying to pull off.
I am able to make a custom tabgroup, but it refreshes each time I change a tab, and I want my tabs to behave like a native tabgroup. Any help would be much appreciated
As you mentioned in a comment, on iOS the tab group it itself a view. You can add views to it, and they will persist regardless of which tab is active. Because you can programmatically change the active tab, you can overlay views on top of the normal tab group and use them to decide which tab should be active.
The following Gist demonstrates this:
https://gist.github.com/853935
I figured out this issue. For anyone that has this same issue in the future this should help: The tabgroup is its own view. If you want to add overlays to it, make a new view, and add it to the tabgroup, NOT to the window itself.
This also looks promising:

You can set a background image for active tab background. The advantage to this approach is that it uses the native iOS API. Actually, it will extend the Titanium tabgroup proxy and add some methods. No hacks required.

I have members complaining that they are unable to tap certain buttons located in a custom navigation bar at the top of my iOS app. The common complaint is that when they do attempt to tap, they see UI that looks like this:
This is about a 200x200 pixel square that appears over the middle of the screen.
We have no code in our app that is capable of drawing that kind of UI. I can only assume this is being triggered by some kind of iOS UI or Usability setting. The only thing I can think of is that we also have a UITabBarController, and the user (in this case) happens to be on the "Browse" tab of my app. If possible, I would like to either a) programmatically disable this or b) inform the user how he can manually disable this UI via an iOS setting someplace.
Can anyone identify what might trigger the UI you see above?
It is a new feature of iOS 11. Take a look at Bar Item Images.
To disable this you should remove an image from Accessibility on Bar Item (see link). But I am not sure how (or even whether) you can define that a user has enabled large content text.
For more info take a look at What's New in Accessibility.
I have a screen with 1 button. When clicking that button, a list of items should be shown (in which the user can select multiple items).
On android, i would like to do this using a dialog. I create a "DialogService" that does this, no problem.
On iOS, however, it seems that the best practice is to display a fullscreen tableview, for example as a modalView. Is it possible to do this without using a custom viewpresenter (e.g. modalViewPresenter)? I would very much prefer to have identical navigation on both platforms and just have different implementations of "DialogService"
I think trying to make one platform look and act like another is generally not a great idea as things start to look weird for the users.
But if you want to do it anyway I would start by trying to do something like this https://stackoverflow.com/a/29910246/1107580 (it is in objective-c) then trying to bind to the tableview that is in the alertcontroller.
I'm trying to create an APP prototype and I was wondering what is the name of animation/transition effect that you see on top of the mailing app when you click the new message button. It's animation effect where the navigation bar does not fully go to the top of the screen and you can the previous view in the background? And is there way to add that animation effect to my storyboard? If not, is there a easily available library that will
I do believe that is a custom transition for which apple does not provide api.
I am developing a dashboard system which I need to split the app's screen into 4 blocks. Each block needs to have a page/tab control with different tabs such as day, month, week, etc
Is this not supported in xcode? I can only see references to a tab control where the tabs are at the bottom of the app's screen
Can you please try one of the control here in http://www.cocoacontrols.com/tags/tab?
I strongly recommend sticking with the tabs at the bottom. If you want them at the top you will have to implement your own solution or find one by someone else.
I am developing an iPad app that needs to have multiple image sources, on the device/Photo Albums, remote and some included with the app. Now the ideal situation would be to have a UIPopover controller with 3 tabs for each source. The only problem is I can't seem to figure out how to have a UIImagePicker be in its own tab. What I am trying to do is very similar to Apple's Keynote for iPad. The photo icon's popover has tabs and the far left tab called media for sure has a UIImagePicker in there. I have no idea how they did that, is it possible for me to do something like that? I think the main issue is that the Image Picker is it's own navigation controller and it cannot be pushed on to another navigation controller. Any help would be greatly appreciated!
check out this - https://github.com/key1jp/ELCImagePickerController
you can implement it with custom asset library
The built-in image picker is no good.
Create your own image picker and add it to your navigation controller as a normal view. Start from either the Matt Tuzzolo or the MyImagePicker from the WWDC 2010 sample code. Note that you probably want to add image and video preview - I copied the image viewer from MyImagePicker and added a 'add' or 'remove' button to it, and the same for video.
Your image picking is in two steps, one for selecting the group, and one for selecting the assets within the group. I recommend dividing the first step into a two - if there is only one, then go directly to that group, i.e. when you have found the first group, check whether that group was the last (block stop argument). Then push the right view controller.
Obiously modify the size of the thumbnails also, they are iPhone size now. Adding a line of metadata (icon and duration) looks much nicer and is more informative for video.
I also recommend adding a 'click-and-hold' function for extended information after like 2 seconds.
Handle different sources by creating a protocol which gives you what you want, i.e.
-(BOOL)isImageAtIndex:(NSInteger)index;
-(UIImage*)thumbnailForUndex:(NSInteger)index;
-(void)setSelectedAtIndex:(NSInteger)index;
Creating a source which handles local files, included resources and assets is perfectly possible - I use NSURLs and check on the url scheme.
Are you not using UITabBarController for your tabs? You should be able to add a UIImagePickerController directly to viewControllers. I'm not sure whether that is a supported use of the image picker, though; the documentation only mentions displaying it modally or displaying it in a UIPopoverController.
It's not usually useful to look at an Apple app to find out what you can do with various built-in controls, as Apple allows themselves to use private APIs.
