I am using Open Flow(Cover Flow) implementation of Alex Fajkowski https://github.com/thefaj/OpenFlow. I would like to a text lable under the images, which should update for each view. I still cant make it work. Would anyone be so kind and give me some further hints where exactly and how to implement this?
Best Regards Regen
Well theres a delegate method (selectionDidChange) that gives you the currently selected index. Hook up a textView to your view controller. Then update the textview in the delegate method "selectionDidChange"

I was asked to display a list of three options for the user in a View sliding from the top to bottom. They say it should slide from the top because the action is initiated from a dropdown-like button on the navigation bar.
Most of what I found on that subject mentions the deprecated UIActionSheet class.
The "new" way using UIAlertController doesn't seem to allow us to change position of the view. At the least from what I've found.
The end result I'm trying to get can be seen on the image below,
From what I've learned about iOS programming, one method I could think to achieve that would be to create a new UIViewController and to use a custom class to control the transition. But it just seems so much. And I think it wouldn't not look like a dropdown afterall.
The other option would be to create the TableView with options and leave it on the Controller where it should be displayed, configuring its height to zero. And then Animating when necessary. I also have such a bad feeling doing it this way.
Is there a right way to do this on iOS? Does one of the options I've found seems acceptable?
Thanks.
Following the suggestion given by #Losiowaty on the comments, I started looking for a custom View/Control on cocoapods and ended up finding quite a few that did what I was looking.
The one I decided to use is this:

So I have added a UIUITableView to a UIViewController. I can't use a UITableViewController for reasons I don't need to explain since it will be unnecessary information. Anyway, I have set the delegate, and the data source to this viewController. I've added the delegate and datasource protocols as well. The cells are populated correctly, so the datasource is working fine. I can also scroll so it all works fine.
However, I can't get the didSelectRowAtIndexPath to trigger. It SHOULD trigger, but doesn't. I've read and a lot of issues with this can be correlated to a UIGestureRecognizer, but I haven't implemented one. I also use the standard UITableView, so not a custom made one.
If I long press the cells (3-4 sec) then it gets triggered as it's supposed to. This suggests that there is some issue with another view or something absorbing the tap gesture, which I have no control over. How would I solve this?
No, it's not didDeselectRowAtIndexPath.
Yes all delegates and datasources are correct, since I can get the delegates/sources to trigger.
Yes, Single Selection is set on the TableView in the inspector.
Yes, everything has user interaction enabled.
If I just copy the code over to a UITableViewController it will work just fine, but right now that is not an option, I'm afraid. Anyone got any ideas on how to solve this? Most people who've had this issue has either had the issues in the list above, or added a UIGesture on top of the UITableView - I haven't.
I want to start by saying that I appreciate all the answers here provided, it gave me a lot of things to try out so I learned a lot - thanks! None of your suggestions worked, but simply because I'm a complete idiot. I said in the post that I did NOT implement a UIGestureRecognizerwhich I didn't...in that class, but in its super class. So I DID in fact implement it, but in a class that this ViewController was a subclass off. The only reason I didn't remember it was because I haven't looked at that super class for weeks.
Someone did suggest it in the comments that I should check for it, and I did and I was already certain I didn't implement one, so I quickly dismissed it. But now, after about 4 hours of debugging and recreating the project, adding things one by one, I eventually realized that the only thing that differed at this point was the Super Class, and the first piece of code I see when I open the file up was a GestureRecognizer...
So keep this in mind in the future everyone - I know I will. Thanks again for the help!
Sincerely,
The complete idiot.
Make sure you don't add any controller in that cell, which covers the entire cell and also the user interaction of that controller is enabled.
Due to that controller's user interaction enabled the tap action is taken by that controller and when you long press that cell, that cell will receive your tap.
Example :
UIView *_view = [[UIView alloc] initWithFrame:CGRectMake(0, 0, _cellWidth, _cellHeight)];
[_view setUserInteractionEnabled:YES];
[cell.contentView addSubview:_view];
In the above case that view got your tap instated of the cell.
I have a 2 UIViewController(s), I need to be able to change the views at the bottom of the Airtime and Data Plan Upon tap gesture on Airtime and Data Plan!
The yellow line will indicate the active view controller. some thing like tab bar.
Perhaps, the image attached is an android version
Could anyone provide a help on how to go about this.
Thanks
I personally use a library called ICVIewPager
https://github.com/iltercengiz/ICViewPager
This is pretty simple and easy to use with examples. It should put you in the right direction without writing a lot of code.
I have a table with cells that the user may swipe to mark them "completed". I am trying to make this accessible using VoiceOver by implementing the accessbilityScroll method.
This works fine, but I can't figure out what cell has focus when the user scrolls.
I only find information on how to change focus.
Hehe, Ok. I just figured it out.
There is a protocol for this. Its called UIAccessibilityFocus
Method: accessibilityElementDidBecomeFocused:
Well, I will leave this question here to any one else that is out there struggling with this.
Your program can also tell where VoiceOver’s “focus” (the object that it’s dealing with) is, and when “focus” enters or leaves any given object.
For Focus Information click here
– accessibilityElementDidBecomeFocused
– accessibilityElementDidLoseFocus
– accessibilityElementIsFocused
As of iOS9, you can use
UIAccessibilityFocusedElement(UIAccessibilityNotificationVoiceOverIdentifier)

I want to implement a signature feature in my tabbar application. I want to add a subView to a UIScrollView or UIViewController (which ever is the more appropriate and easier). Which control should I use for it?
I want to pick the touch events on the signature view and draw on those points to get the signature. Any help would be highly appreciated.
You can use just a UIView for drawing points get touched. I needed to implement something like that and the following page was really helpful. It explains all with code. You may want to check it out.
