I'm making an application that requires the use of a dock (think Mac dock) where I can have different items that I can drag out onto a map view.
It would make sense to me to just use and subclass a UITabBar, since you can easily add items to that bar in the interface builder. However, I'm not sure how I would transform a UITabBar into something more dynamic like the Mac dock, where things are only highlighted when the user touches them, copies of that tab can be dragged out, ect.
To that end, just a side question, what's the difference between the UITabBarDelegate and UITabBarControllerDelegate protocols?
I also thought of another way I could implement my task bar/dock using some sort of collection view with UIImageViews. That would be easier in terms of implementing drag and drop, highlight selection, ect but I would lose that nice, native iOS feel that the UITabBar has.
Any suggestions?
do one thing. create a custom class for tabbar add a view over it. and add image views over the view place small images in that view and add gesture recognizer over it. When the finger comes over it replace the smaller image with the larger one. and also change the tab bar selection if the user taps over it. you can do this by using tabbar property. or you call the tabbar delegate manually when the tap is made.

Is it possible create such element on base UITabBarController?
If not, how do you advise create it. Thank you,
Is it possible create such element on base UITabBarController?
No, you cannot add your own controls to a tab bar. The tabs in a tab bar should be used as they're intended, i.e. to switch between several different view controllers.
If not, how do you advise create it.
I recommend that you don't try to create something that both switches between view controllers and also does other things. That said, if you want to add controls that work differently from tabs in a bar at the top or bottom of the window, UIToolbar is the right class to use. You might be able to create a subclass of UIBarButtonItem that has radio-button functionality similar to what UISegmentedControl offers, and you could then use that with UIToolbar.
I do not think you can easily add a UISegmentControl to a UITabBarController. If you check Apple Documentation UITabBarController accepts UITabBarItems which can be initialize with either an image/String or with one of the preset cases.
You could create your own TabBar and then add a UISegment Control onto that, but if I was you I would use the normal UITabBarController and make the two buttons one next to the other with images that makes it look like a segment control to the user.
The issue with this approach that the TabBar is not supposed to be there for you to have more than one item selected at a time. So you could not have notes and All selected at once.
It might be easier for you to add the UISegmentControl onto a UINavigationController at the top of your app, and then use the TabBar normally.
That is what I would do in any case.
I am creating an app using Swift, and I'm still trying to figure out what the best configuration would be.
What I'd like to have is 3 screens (the left screen would have a side out panel) that users can access via the navigation bar menu or just by swiping left/right the screen for more accessibility.
I could easily create my TableViewControllers/CollectionViewController and the menu, but I'm struggling at making the screen able to detect users gestures at the same time, and I'm not sure whether I should use 3 View Controllers and then add the Collection View/Table View via the Storyboard, or directly use the CollectionViewController/TableViewController
I added a picture here describing what I'd like to accomplish:
Also, I wonder whether I should use storyboards or not for my project.
I know that's a lot of questions !
Any ideas please ?
Thank you very much and have a good day,

You need to add 2 "swipe gesture recogniser"s to your middle screen(your second screen in your attached image) , and set one for identifying left swipe and another for right swipe. Create action methods for both in your view controller and add code accessing left screen and right screen in respective methods.
note - you need to drag "swipe gesture recogniser" to top bar of your view controller scene to add it.
You can use a scrollview as a container, put three ViewController in it.
I would like to know if someone have an idea about how Tapbots made Tweetbot3 TabBar?
In my app, there will be many TabItems, and I don't want the "More" Tab (by default), but I'm very interested to have a similar system to Tweetbot, with a "picker" which opens on long press gesture on a TabBarItem.
But, I'm hesitating on the method. It's better to apply a customized UITabBar class, or to totally "deconstruct" the UITabBarController (to use a UIViewController and a custom "tabbar")?
Having created many custom tab bars, I'd start by subclassing UITabBar and UITabBarController. I wouldn't expect any roadblocks with this approach.
You may want to move the default buttons around and then add some custom buttons. Send a message back to the tab bar controller and let it display the popup choices view.
I need to create below thing
Currently i'm using WYPopover , but I can't create the button since it's outside of the popover. Is there any existing solution out there ? Many thanks
Create a bigger popover UIView holding all your child elements (current popover + button) and make its background transparent or however you wish.
Popover-controller's are exclusively used in iPad. If you want to use in iPhone, you should create it in a custom way.
I am not familiar with the XYPopover in Github, but normally the custom created popover should be dismissed whenever the user taps any place in the screen. That is one of the key feature of the popovers.
Normally the custom popovers are build like, adding a hidden parent view and then the visible image of a popover frame on it.
You should to do the following,
Avoid dismissing the parent view on tap of parent-hidden-view.
Add a close button at the area where you want to show the close button, on top of the parent-hidden-view.
Capture the button click and dismiss the view (remove the view from superview)
How to customize your need
Creating custom popover view is not a big task. It will take maxim one day, try it your self.
One Parent view with clear color
One background image of a popover frame.
View-inside popover (this needs to be customized for UIPopover also).
Close button.
I am developing an application that requires a scrolling UITabBarController. The customary 5 tab items max with the 5th being the More.. tab just won't do. I have found some pretty great third party classes such as https://github.com/Marxon13/M13InfiniteTabBar and they are great and have the functionality I would like but still, things aren't perfect. When I rotate my device to landscape things become glitchy.
Basically, I am fed up and want to create my own custom UITabBarController with scrolling..how would I go about doing this? I understand I would most likely put a UITabBar within UIScrollView but I am lost without a detailed tutorial of sorts..
Any help would be greatly appreciated! Thanks!!
The way I would approach this is to avoid modifying the UITabBar, since it is highly specialized, and create a UIViewController subclass that will provide this functionality for you. This view controller should have a container view (take a look at this Apple documentation for more detailed information) that will have each child view controller's content view.
For the actual tab bar itself, you have a few options depending on what you similar you want it to the standard UITabBar.
You could have a super basic tab bar that consists of a UIScrollView with standard UIButtons that change/load the correct content view controller. Creating the tab bar would be then easy, simply add the buttons to the scroll view inside some type of loop (you could have the x positions be a multiple of the tab index to make positioning easier). UIButtons have support for a selected button state that you can use. You can change the scroll view's background.
You could have a fancy tab bar which is constructed essentially like the above, but by having a custom UIButton subclass instead of a standard UIButton. This will allow you to implement a more intricate design (i.e. with and more customized touch handling.
Tips:
Use [myImage imageWithRenderingMode:UIImageRenderingModeAlwaysTemplate] to have your tab images tinted like the standard tabs when selected.
Design the basics of your custom view controller in your storyboard. It is really easy to add the child container view and the scroll view this way.
Hope this helps!
