QUESTION
I'm trying to learn to build views without storyboard. I tried to build a scrollview. On that scrollview is a UISearchBar, a UIImageView with an image and a UILabel. It works but none of the content moves. The content is all just frozen in place like no matter how far I scroll the search bar will always be on top of the page. and the image on the bottom. I've attached a video to show what I mean. There's also a problem because none of the content is where I want it to be but that's another problem. I realize this is probably because I don't know enough about constraints and autolayout and building views without storyboards.
...ANSWER
Answered 2022-Mar-08 at 22:05First, when constraining subviews in a UIScrollView
, you should constrain them to the scroll view's Content Layout Guide
. You're constraining them to the view's safe area layout guide, so they're never going to go anywhere.
Second, it's difficult to center subviews in a scroll view, because the scroll view can scroll both horizontally and vertically. So it doesn't really have a "center."
You can either put subviews in a stack view, or, quite common, use a UIView
as a "content" view to hold the subviews. If you constrain that content view's Width to the scroll view's Frame Layout Guide
width, you can then horizontally center the subviews.
Third, it can be very helpful to comment your constraints, so you know exactly what you expect them to do.
Here's a modified version of your posted code:

QUESTION
I am trying to get this part of my code to create a channel and add the user to the channel to see and type but can't post images.
...ANSWER
Answered 2021-Jun-17 at 06:45You should have a look at the valid permissions as post_images
is attach_files
.
create_text_channel states the overwrites are
A dict of target (either a role or a member) to PermissionOverwrite to apply upon creation of a channel. Useful for creating secret channels.
guild.member does not exist because guild is a Guild object. Use member
instead as stated by the quote.

ANSWER
Answered 2021-Jun-06 at 06:35Ok I figured out your issue.
In your "stylesheet.css" you have this code:
QUESTION
package com.company;
import java.lang.reflect.Type;
import java.util.Scanner;
public class Main {
public static void main(String[] args) {
// write your code here
Scanner nameInput = new Scanner(System.in);
System.out.printf("As of right now I noticed you have not selected a weapon. Please choose from the following selections that I recommend, I current have no information on your shooting style.\nSo these recommendations are based souly on beginner levels.");
System.out.printf(Gun.Type);
}
}
...ANSWER
Answered 2021-May-08 at 17:24You have multiple problems with your code example. Here are a few.
The gunList
method is declared as returning a String
. But you do not return a string. Instead you print to System.out
, a PrintStream
object. Change that to capture the generated text as a String
. See Sprintf equivalent in Java. Return that string object using the return
keyword.
There is no need for the public String Type() {
. (Also, methods in Java should be named starting with a lowercase letter.) Just instantiate a Guns
object, and call gunList
method. (Also, using “list” here in this method name is a poor choice, as that word has a specific commonly-used meaning in Java.)

QUESTION
I am new to python and I don't really understand the sql thing that well. Currently on the 6th week of team treehouse so please bare with me here if these are noob questions.
Goal
- Import CSV with stock_tickers and 5 other columns of data
- Convert CSV into pandas dataframe
- Import dataframe into database. If there is already the unique stock_ticker for it to not add a new row, but next to check if the data in the other 5 columns is different. If it is than update it.
Right now I can do steps #1 and #2 and half of #3. With the help on here was able to get the looping thing to work. If there is a new stock_ticker row in the csv it will add it to database. If the data changes for an existing stock_ticker it won't do any updates.
