How can I do to have a title, followed by a few lines of text, followed by a title again and again few lines of text constrained in the middle of a view controller programmatically?
My goal is to have bolded for the titles, and it would be nice to have the textview lines incremented also.
My idea was to create 2 labels, and 2 textviews. And adding those to a textview in this order: label1, t1, label2, t2.
But it doesn't seem to work. I try to avoid defining the same textviews and labels many times. textviews add up if I copy its definition twice but not for labels (maybe it is view related?)
I tried with UIbuttons and it worked.
This is what I tried so far:...

UITextView are both UIKit classes written in Objective-C. They are reference types, NOT value types.
When you write following -
I am a beginner in Android development. I am trying to study the use of Graphstream (https://graphstream-project.org) in an android app. I have created a basic activity with a drawer layout which includes a navigationview and frame layout where I intend to display the graph.

First, you shouldn't need to scale the image - using
.contentMode = .scaleAspectFit on your image view should work properly.
The problem you are hitting, though, is you're setting the image on the wrong image view...
I'm pretty new with SwiftUI and I'm encountering a really unnerving issue.
I've created some custom views that are being shown with the right height inside the preview. When I try to add them inside a VStack, they behave instead like I'd set
.frame(minHeight: 0, maxHeight: .infinity). Adding a
Spacer() after the custom view, inside the
VStack, do not solve the issue.
I don't know the size of those views in advance so I can't set a fixed frame size, is there anything I can do to prevent this behaviour? I even thought about calculate their content size and apply a fixed size accordingly, but it sounds like a developer nightmare :|
Thanks for reading, and for the help!
EDIT: The most simple code that raises the issue:...

GeometryReader is the root view of your ChipGroup. GeometryReader always takes up the most space possible, expanding as much as possible.
If you don't want your view to take up all the space, you need to get rid of the GeometryReader - unless you want to set a fixed height, which you specifically mentioned you'd like to avoid. That's just how GeometryReader works.
I have a UICollectionView where some of the cells should have a dashed border and some of them should have a solid border. Also, the cells can be of varying size depending on the content that is present in the data model.
The problem I am having is that I cannot get the dashed border to be the same size as the collection view cell and again, the cell size can change based on the content. But basically, the cell should either have a dashed border or a solid border. The solid border is easy to get to resize to the correct size.
Here is a picture of what it looks like right now. The dashed border is colored green just to make it easier to see.
Here is the view hierarchy debug view. There are two dashed borders here because I have been experimenting. The green border is a sublayer on the UICollectionViewCell's root layer. The grey border is a sublayer of a separate view that is a subview of the collection view cell's contentView property.
Here I am trying to add a UIView subclass that has a dashed border. Then, when I need to show the dashed border or hide the dashed border, I just set the
hidden property of the view accordingly. This works fine, except I cannot get the dashed border sublayer to resize.
The view is resizing to be the correct width and height based on the AutoLayout constraints, as can be seen in the view hierarchy debugger screenshot above. But the sublayer is still the original size (approximately 50px x 50px, which I guess is coming from the UICollectionView because I am not specifying that size anywhere).
For this implementation, I have a custom UIView subclass called
MyResizableSublayerView. It overrides
layoutSublayersOfLayer to handle the resizing of the sublayer, or at least that is what is supposed to be happening, but clearly it is not working.
But then the
MyResizableSublayerView class is used in the collection view cell to add the dashed border to the view hierarchy.

It's not quite clear what you're doing with constraints on the content view ... however, if you are getting the layout you want, except for the dashed borders, give this a try.

I've been scratching my head about this all day. I am try to have the iphone 6s reflect what the iphone 12 is showing. I'm not good at autolayout but I'd just like an idea or a point in the right direction so I can make it look like its counterpart. All help is appreciated.
(P.S I'm using storyboard and have never tried to do it programmatically.)
All help is appreciated....

It's all the game of constraints if you want to handle this using story board.
There are multiple ways to achieve this UI. Either you can use UICollectionView and use UICollectionViewCells to show 2 cells in each column to manage the data or you can use UIStackView to manage your UI easily.
If you want square shapes, then you must use UIScrollView as the UI can exceed Screen Height. If not, just put your view in UIStackView and let it handle some of your UI constraints itself.
I'm working on making scrollview programmatically using snapkit, it works scroll but the problem is that the last element(systemTeal color tempView) can't see fully.
I create contentView inside Scrollview, which is containing every element....
ANSWERAnswered 2021-May-18 at 03:09
I think the problem might be the use of
make.edges.equalTo. It'll statically set the edges of the superview to your scrollview and content view, not constraining top, leading, trailing, bottom anchor to the superview. I suggest you to try with 'make.top.leading.trailing.bottom.equalToSuperview()' instead.
I am trying to get the second last value in each row of a data frame, meaning the first job a person has had. (Job1_latest is the most recent job and people had a different number of jobs in the past and I want to get the first one). I managed to get the last value per row with the code below:
first_job <- function(x) tail(x[!is.na(x)], 1)
first_job <- apply(data, 1, first_job)...

You can get the value which is next to last non-NA value.
I was tasked to solve this bug in the app (It's for comercial use so I can't link the project). I'm also completely new to Objective-C or IOS development and I have no idea why the following happens. Reminder, I'm using custom cells.
When the tableview loads, everything looks fine. Click here to see the example
But when I scroll up and back to the same postion the cell becomes blank, as if it had no data. Blank cell
If I repeat the same process everything looks fine again.

Register your cell nib in storyboard or in code before tableview is loaded, and after replace
dequeueReusableCell... with this one
I am trying to implement a table view that allows the user to "show more" rows to toggle the full number of rows or a smaller number of rows. I have all the data upfront when the view is loaded, so I do not need to fetch any extra data.
I am able to get it working, but the problem I am having is that my table view does not smoothly animate when expanding or collapsing. What happens is that if the "show more" action is triggered, the size of the table is updated all at once to the full height of the table with all the data in it. Then the rows will animate.
Likewise when hiding rows, the table height will shrink all at once to the end height and then the rows will animate.
Here is a picture of what is happening. It just "jumps" to the full height and then it animates the rows. But what I would like to happen would be for it to smoothly expand the height of the table unveiling the data as it smoothly expands downward. I would like the opposite, where it smoothly slides upward when pressing "show less".
The way my app is laid out is as follows:
UITableView<-- the section I am working on here
Basically, I have a scrollable list of sections of different data. Some sections are tables, some are just ad-hoc views arranged with AutoLayout, others have collection views or page view controllers or other types of views.
But this section is represented by the UITableView in the previous list....

You really have a bunch of questions here - but to address specifically the issue with trying to expand/collapse your table view...
I think you'll be fighting a losing battle with this approach. By trying to use an "auto-sizing" table view, you're counter-acting much of a table view's behaviors/ And, since you are not getting the benefit of memory management with reusable cells, you're probably better off formatting your "spec list" with a vertical stack view.
In either case, to create a collapse / expand animation with a "reveal / hide" effect, you may want to embed the tableView or stackView in a "container" view, and then toggle constraint priorities for the height (the bottom) of the container.
Here is a quick example...
- create a "container"
- add a vertical stack view to the container
- add labels to the stack view
- add a red
UIViewto place above the container
- add a blue
UIViewto place below the container
- define constraints for the height of the container
On each tap, the container will expand / collapse to reveal / hide the labels.

You can use AutoLayout like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the AutoLayout component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .
