QUESTION
I want to implement a popup notification into my app when data was being updated successfully or not. To do that I:
created a .xib file: Screenshot
created a class where I load that NIB:

ANSWER
Answered 2022-Mar-30 at 02:58I do not use XIB and storyboard too much these days so I also had to refresh my memory and I used this tutorial
This is the custom PopupView class, I prefer not to use singleton for this but it is my personal preference

Answered 2022-Mar-29 at 23:31Fields in classes ServiceLine
and Provider
have package-private
access modifiers. Jackson can't deserialize into private fields with its default settings. Because it needs getter or setter methods.
Solution 1: Make fields public
QUESTION
ANSWER
Answered 2022-Feb-16 at 17:40Doing it the way you are doing it right now is a way to do it but I think it is the most challenging way to do it for several reasons:
You don't have much control and access to the implementation of the search controller animation within the navigation bar so getting the right coordinates might be a task
Even if you did manage to get the right coordinates, trying to synchronize your animation frames and timing to look in sync and seamless with the search animation on the nav bar will be tricky
I suggest the 2 following alternatives to what you are currently doing where you will get the news experience pretty much for free out of the box.
Option 1: Use a UITableViewController instead of a UIViewController
This is all the code using a UITableViewController
and adding a UISearchController
to the navigation bar.
QUESTION
I am using AVPlayerViewController to play mp3 audio files. I can get the player to appear programmatically with no problems. I have also added subviews in order to set an overlay for an imageView and textView. This works fine but I cannot get the textView to scroll. I was able to test the same basic code using just a regular UIViewController and the textView scrolls fine. So, I'm wondering if there's an issue with scrolling using AVPlayerViewController or if I've missed something. Please note: This is NOT a duplicate of my other post about AVPlayerViewController. In the other post, I'm asking if it's possible to use Storyboard somehow to customize in this way. Any help/suggestions regarding scrolling here would be greatly appreciated. Code is as follows:
...ANSWER
Answered 2022-Feb-12 at 10:45There are a lot of gesture recognizers already present on an AVPlayerViewController
to pan
, pinch
etc to either interact with the media and / or dismiss the AVPlayerViewController
once presented.
Because of this, I believe your UITextView does not receive it's interaction events and so nothing happens when the user tries to scroll.
Infact, Apple documents that the contentOverlayView
of the AVPlayerViewController
should be used for non interactive views.
contentOverlayView
A view that displays between the video content and the playback controls.
Discussion
Use the content overlay view to add noninteractive custom views, such as a logo or watermark, between the video content and the controls.
What I suggest is the following like I suggested in your other question:
- Create a custom
UIViewController
- Add the
AVPlayerViewController
as a child view to this custom view controller - Add the
UIImageView
and theUITextView
to this customUIViewController
and not to theAVPlayerViewController
Here is how I would do that is as follows:

I have a dataframe of conditions that are time based. I would like to compare the time in a set of data to the start and end times in the conditions to give the correct condition. I was thinking of using purrr to map a function to do this, but I'm stuck.

QUESTION
I have a simple table storing teacher-student relationships to show who's class students are taking or who the teacher is teaching. Either way. (Sorted by Teacher for readability)
...ANSWER
Answered 2021-Dec-30 at 10:43This is a problem known as Relational Division Without Remainder. There are a number of solutions. Here is one:
Firstly, you must pass all your values to SQL as a table, for which you will need a Table Valued Parameter (shown below for C#).
I'm going to assume that TS_RELATIONSHIP
is unique over the two columns, and that the input list of students is unique also

I'm not sure what is going on, but every time I try to run this in my R script, I get no issues. When I run it in R Markdown, it produces errors despite pre-loading all of the necessary packages and data. I will list the error below. First, I will show what I have for a script.
Here is the dput for my data:
...ANSWER
Answered 2021-Dec-23 at 07:48You need to know the current directory before executing the code. You can get it using getwd()
.
The working directory of your R console and the working directory of the R markdown
file that you have created is different.
R markdown documents are compiled separately in separate R sessions. So your, current R console has nothing to do with the compilation of the R markdown documents.
Once, you get the current working directory with getwd()
. You need to change it with the correct path where your R markdown
file is saved using setwd()
.
EDIT The only thing I did different that your code is as follows:
QUESTION
I am using AVFoundation to merge two videos into one. The result of my attempt is a single video with a length equal to the sum of all the clips, and displaying a black screen.
Here is my code:
...ANSWER
Answered 2021-Nov-25 at 12:25You are inserting every time range at CMTime.zero instead of at the end of the previous asset. Also, are you using a videoComposition when you export?
UPDATE: A long time ago I was doing video playback within the app so I don't actually export, but when I first started I exported first then passed the exported video as an AVAsset into AVPlayer. I changed a lot since then so I don't export the video just to playback within the app because it was inefficient and a waste of time, but my code works perfectly in terms of merging assets together. I had it working when I was exporting, but I also changed my merge function a lot since then so no guarantees this will work with an export session.
