I am implementing a way for the user to see a time-stamp for all messages when the any message is swiped to the left. Similar to the way iMessage does it.
(source: tekrevue.com)
Approach 1:
I invested some time in researching on StackOverflow. The nearest I got an answer to my problem:
How to Show time like iMessage iPhone app in UITableView
This question was asked in 2014, is meant for Objective-C and the only answer suggests to implement a Pod. I am gonna be honest with you, I am not a big fan of Pods. They do slow down my project.
(To be fair, the GitHub mentioned in the comments of the linked question was updated to Swift)
Approach 2:
After the first Approach, I was thinking about using Cell-Actions / Swipe-able TableView Cells.
The idea was to replace the buttons by a single label. This would get the job done but it wouldn't "feel the same" as the users are used to from iMessage. Only one message would slide instead of all messages and when the user stops swiping, the cells/messages wouldn't animate back to their standard position.

an iOS app page, which descirbes some item's detail
This is kind of what I want to make
This is exact what I want
Actually I am not an iOS developer.
But a member of our team lacks of knowledge of consisting of iOS app Page(Scene)
I think he usually use table view all the time. which I guess he can't handle very well.
He always struggle about height of UITableView in dynamic pages.
As you see in the picture, page has two views, which I don't know how to call it.
If round button on the right side of a woman is pressed those two views switches.
I guess it's kind of "TAB".
Is it normal that using UITableView in this kind of page. or Which is best practise?
Thanks in advance and sorry for my english.
The first image can be made using a UITableView or UICollectionView(UITableView will do the job with lesser hassle). For second image, you'd wanna use a segmented control.
The third can be built using UICollectionView, however, there are plenty of third party libraries out there on github for the same and you might wanna check them out.
Last but not the least, have some faith in your developer. He seems to be a newbie if he's facing troubles with tableviews but believe me, we've all been there some day.Encourage him to ask questions on various communities. If he's curious enough, he'll be just fine after a while.
While many UI-elements are easy to create in SwiftUI, there´s one I'm struggling with. I don't know what it's called, but I'm talking about the bottom-search bar which turns into a full-blown sheet akin to the one shown when calling .sheet(isPresented:) when dragged up.
Here's a visual:

I realize there's a good chance this isn't possible yet, but I thought asking was worth the shot :)
In CareKit there are Care Card and Symptom tracker. I'm not understanding how to customize Carecardviewcontroller and symptomtrackerviewcontroller. I don't want to use these view controllers but interested in using components of these view controllers. there is no clear documentation to explore this.
(source: carekit.org)
If you are coming at this from a Swift perspective, then it has to be admitted that CareKit is about as "un-Swifty" as anything you can imagine. The GitHub site is certainly a start, but there is a horrific gap between reading the programming guides there and actually implementing a solution. It certainly has been a long slog for me!
That said, you can add customization to CareKit's story-board-free approach by using the view controller delegate functions that CareKit provides.
For example, suppose you have an app that reminds your user to perform two intervention activities, (1) take aspirin and (2) go for a brisk walk. If the user opens the Care Card and taps an event icon (one of the circles) for "take aspirin" then that will fire a method in the OCKCareCardViewControllerDelegate called:
careCardViewController(_ viewController: OCKCareCardViewController,
didSelectButtonWithInterventionEvent: OCKCarePlanEvent)
In this method you can segue to whatever view controller you'd like. E.g. if the event is for taking aspirin then display a view controller that shows a photo of an aspirin table, a reminder that it should contain just an 81 mg dose, and a recommendation about taking it with water.
Of course, nothing is ever easy with CareKit. It turns out that you will probably also want to turn off CareKit's standard practice of calling an event completed if the circle icon is tapped. That is accomplished by returning "false" from another delegate method called:
careCardViewController( _ viewController: OCKCareCardViewController,
shouldHandleEventCompletionFor
interventionActivity: OCKCarePlanActivity )
-> Bool
There is a book called Beginning CareKit Development that I can cautiously recommend. It was written for an earlier version of Swift and you have to do a lot of "translation" to get things to work with Swift 3. The last time I checked the GitHub repository for the code associated with the book was also entirely in this earlier version. APress will provide the code updated to Swift 3 if you ask. On the Kindle there are numerous little glitches with the book, including an index that has no page numbers nor hyperlinks to the associated text, very odd formatting choices that make the text sometimes hard to distinguish from code, and occasional errors in the solution code. All that said, I doubt that I'd have made any progress with CareKit without the book's help.
I've been looking for this answer myself.
As far as I researched, you can customize this screen visually with UIAppearance.
AND/OR you can create a new screen like this one from scratch using its behavior.
You can check the CareKit source code for hints on this: https://github.com/carekit-apple/CareKit/tree/master/CareKit/CareCard
There you'll notice some interesting classes/files:
OCKCareCardWeekView
OCKWeekLabelsView
OCKHeartView
OCKHeartButton
OCKWeekViewController
OCKHelpers
CareKit draws each screen via code. You can see how they do it by reading the code.
The idea is to create your own ViewController with these pieces, or one from scratch.
Surely it's not as trivial as just using CareCardViewController, but this will get you there.
Here is context for my question, this is an optional read:
I have to develop an app for a
school project. At the end of the year some people I don't know will
listen to me presenting my app, and review my presentation and my app
(note that they will probably not be app developers, they are usually
IT professors) (note also that I'm allowed to ask for help to anybody,
and I can use internet since I do this mostly on my "free time")
So since October I'm developing my app, that takes a lot of time
because this is my first app. And here comes the issue:
My app is a giant Scroll view with 5 NavigationsControllers, each containing a ViewController. These ViewControllers sometimes have buttons that leads to an other ViewController. The problem is when I use these buttons, and another view controller is displayed, when I swipe right or left the ScrollView scrolls and another ViewController from the scrollView is displayed. I don't want this to happen because most of the time the ViewController displayed after the tap on a button is not meant to stay, it's generally a form to send data to the server.
As I think this is difficult to understand, you can download the project on Github
Is there a way for me to disable scroll on chosen ViewControllers? or should I change everything to avoid using a ScrollView?
Bonus question:
Is it a really really bad idea to make an app this way, or did I just miss something?
Thanks for your help!
The new facebook app has a new feature. There is a little circle in the bottom of a message that means where is the user in the conversation. (hist last seen message).
It is pretty awesome, but i couldn´t figure out how it was developed. I´m pretty sure they created a new cell type, to show where is each user in the conversation. And then, if the user reads it, it just update the table and the user will be in another message that he just read. This would be ok.
But my question is, during this transition, the little circle is animated from the current message to the new position, and the others little circle are animated to make space for the new coming little circle. How is that possible? To animate something on top of a listview?
Thanks in regards,
Can you give me a screenshot of what you're talking about so I can look at it, or give steps to get to the screen you're talking about?
Facebook does some pretty remarkable stuff with iOS. If you want to see some of the crazier things, check out the app Paper that was developed using the Pop Framework. In there you might find some of the UI actions you're looking for.
