QUESTION
Background
I need to get a square image to fill a table cell side to side, with a small margin, and have it work across all devices.
The approach I've taken to deal with different devices is to programmatically set the row height in the table based on device and use AspectFit to cause the image to fill the row -- which works well when I know what value to set the row height to. It only takes a couple of guesses to get it right.
Problem
The way the image looks in the simulator is different than the way it appears on a real device, making testing impossible on the simulator and requiring real devices to be certain.
Is this a known problem with images and the simulator? Is there some workaround or setting that I am missing?
I would like to get the simulator presentation to match the device presentation with respect to images so I can test effectively without access to a slew of physical devices.
Thanks in advance.
Reference Images
The first image is from the iPhone 6 simulator. The second (correct one) is from a real iPhone 6 device. You would not guess from the simulator that the image is correct on the actual device.
We have also seen this problem with other simulators, such iPhone 7 simulator, and iPhone SE simulator, so we assume it is a problem with all simulators.

Answered 2018-Jun-20 at 15:05As per comments discussion, the original issue was due to the Device display options being set to Zoom. Once Zoom is turned off, the Simulator again matches the device.
On a separate note... I'm assuming the goal is to have the image centered in the cell, with a bit of padding (20-pts or so) on each side, while maintaining a square shape? If so...
I'd suggest creating a custom cell class.
Add a UIImageView
with constraints of Top: 0, Bottom: 0, Leading 20, Trailing: 20
. Then set the image view to have a 1:1
ratio constraint.
Now, the image view will "auto" stretch to the width of the cell (minus the padding) and auto-layout will set the Height to match the Width. No need to do any manual calculating / setting of row height.
QUESTION
I am facing an incomprehensible problem I have a CollectionViewController and I want to make a custom animation. My collection is a gallery and I want to switch from collection gallery. to fullscreen gallery.
So I have ControllerTransitionDelegate
...ANSWER
Answered 2018-Jan-18 at 09:57Well, I checked and noticed that transitionContext.viewController(forKey: .from)
is NavigationController.
In line: let fromVC = transitionContext.viewController(forKey: .from) as? NavigationGalleryViewController
should be nil, because it is not NavigationGalleryViewController but NavigationController.
If you want you can make smth like this: let fromVC = transitionContext.viewController(forKey: .from).childViewControllers.first as? NavigationGalleryViewController
QUESTION
I'm using CocoaPods to integrate open-source libraries to my app and VSC, saying BitBucket to keep track my project.
Scenario: I use a computer (at work) to add new libraries to Podfiles
, and then use another work station (at home) to pull data from the remote repository, it will require me to do pod update
for the new libraries added using Podfiles
, which is ok.
Point is as long as I do pod update in the home computer, it will generate files asking me to add my repo. Should I also keep track those files?
My expression may not be very clear, so I take SwiftPhotoGallery as an example. I use SourceTree as my Git client.
...ANSWER
Answered 2017-May-28 at 23:52If you are asking whether you should be versioning library files used by your Swift program, then the answer is most likely no. Instead, you should just allow CocoaPods to manage libraries anywhere you want to develop your project. There are many reasons not to version your Swift library files. One reason already hinted is that CocoaPods will probably do a much better job than you in keeping library files up to date. Another reason is that in general one should avoid versioning binary files with Git because it does not handle binaries well.
