I think it's related to this question:
What is "off screen" and "on screen" in Xamarin.Forms Animations?
Unfortunately the answer doesn't help much nor explains what's " element's input layout" or how to change it (besides that X property of an visual element is readonly)
My scenario is like this: I've got a grid of elements. When an element is clicked I want to scale it 2 times. The problem is that its "clickable" area remains untouched. I tried to call layout method but it doesn't help.
So my question is: How to adjust "element's input layout" after transformation?
For more info look for the "element's input layout" here:

I really need your help.
I'm new at developing Xamarin.iOS apps and now I'm totally stuck.
I cannot get the hang of how to implement a dynamic ScrollView in iOS, it was fairly easy to implement on Android.
So what I'm trying to implement is a view that contains mostly text (that will be quite long, hence the scrolling, but also two buttons.
Here is a gif in Android showing what I'm trying to achieve
The view is like this:
Header
Long text
Copyright button
-- Copyright text
Terms of usage button
-- Terms of usage text
I have struggled with the scrolling so long and I really need your help.
All of the text properties are getting bound to the view by binding with MvvmCross so the view can't be with hard-coded heights and widths, it needs to adjust properly.
Can somebody please show me with a sample project how to implement it?
The view needs to be in a .xib view (because of MvvmCross) and it cannot contain a UIViewcontroller.
So the solution needs to be in a simple UIView
I'm working on a Windows, with Visual Studio 2015 enterprise, and I cannot use a Mac (and Xcode) other than to compile my code with.
What I've tried is a solution like this:
UIView called "MyRootview"
-- UIScrollView called "MyScrollView"
-- -- UIView called "MyContentView"
Can you please help me?
Method 1:
Use a TableView instead of ScrollView. Make the header row 1, long text row 2, button 1 and it's text row 3 and button 4 and it's text row 4.
Give row height for the last 2 rows so that you only see the button and on button click increase the row height and reload the table section.
Method 2:
If you keep wanna using ScrollView, put the button data in a label and give it a height of 0 (and number of lines 1) to hide it and on button click remove the height constraint and set the number of lines to 0 (max).
I used FluentLayout instead. Very easy.

I have perhaps a beginner's question but have not found any solutions addressing this specific problem after searching endlessly on stackoverflow and other forums.
My detail view in the storyboard appears to be too zoomed in. At this point, zooming in and out simply zooms in and out on the storyboard, but not the detail view specifically.
Indicators of this are that the alignment arrow to the left of my button is not positioned at half-latitude of the Detail View box, although when I align my button to this marker I do see a crosshair indicating that my button is "centered".
Detail View - Further Out
Upon simulation, it is apparent that using these crosshairs produces a run-time alignment far right and up from being centered. Where my button is currently placed seems to be in the center of the simulator screen but would like my guidelines to allow the button to be centered using the guidelines suggested.
Simulator View
A) How do I "zoom out" within the Detail View so I can see the entire screen in the detail view?
B) How can I center my object if the guidelines are inherently off-center?
Thank you so much for you advice and input.
Are you using constraints to keep the various controls in place etc...?
If not try:
Select all elements in the UI of the detail view. Click on an empty spot somewhere in the View and press CMD + A.
Click on resolve auto layout issues at the bottom right of the Nib editor. (it's the right most icon)
Click on Clear Constraints
Click on resolve auto layout issues again, then Reset to Suggested Constraints
From here, tweak your constraints as per the UI you're working with i.e. iPhone, iPad and whatever orientation it's in etc...
I forgot to mention how I fixed the "too zoomed-in" problem.
In the storyboard controller, on the left navigator panel, within the file inspector, I simply unchecked "Use Size Classes" within the Interface Builder Document section. My view controller changed into a normal iPhone shape and everything finally fit into place.
I have looked at many tutorials and just can't seem to get Buttons to resize and layout properly using Xcode 6 auto layout.
The tutorials that make the most sense just use Views as examples.
Trying to build a Universal soundboard app with buttons arranged in the attached picture.
I also tried putting all the buttons in one View container but still no luck.
What am i missing?
Thanks so much
Select the button you want the constraint on, and command click it's parent view.
Next, select add new constraint (at the bottom of xcode), click "Equal Widths", then click add constraint.
Select the object.
Double-click on the constraint rectangle (not obvious! "Edit" takes you somewhere else)
Then at the right hand side of xcode the attribute inspector should
come up:
At the multiplier property you can make a ratio or a decimal of the percentage value you want. If you want the button to be one fourth of it's parent view, then set the multiplier to 1:4.
This might not be the most ideal answer, but it's the best I can offer. Hope this helps!! Good luck!

After much reading and experimenting, I still cannot get a simple TextView to resize fully in the horizontal direction using Xcode 5.0.2 in Mavericks. It resizes partially as the window is resized, then stops with long lines wrapped around even though my containing NSScrollView continues to resize as expected (it has four default constraints and no horizontal scroller).
Can anyone point me to a simple code/IB+AutoLayout example, preferably just a window containing just an NSTextView dragged in from the IB template library --- one that works? The Apple TextEdit sample code is almost irrelevant for this purpose although it does resize horizontally quite well. Also, there is the clip view for which I can find little information.
Any other tips appreciated.
Thanks.
Answering my own question:
Turns out that my problem had nothing to do with AutoLayout and little to do with NSTextView. It was the textfile I was using to test my code! This file was composed of records with tab-delimited fields.
Turns out that NSTextView comes with a default NSParagraphStyle with predefined tab stops that end at character 56 whereas my test file had tabs beyond that. Therefore, my lines wrapped around at the last defined tab no matter how much I stretched the window.
After changing my search terms, I found what I needed at the following links:
Premature line wrapping in NSTextView when tabs are used

Apologies for wasting bandwidth.
Not sure why such a simple thing does not work in your case, but nevertheless here's what I did in Xcode to get an NSTextView follow window resize:
Create a new project (not document based in my case but it doesn't really make a difference)
Drag a NSTextView from the palette to your window. Align all four edges with the window edges.
Open the "Add constraints" pop-up (second button from the segmented control on the bottom-right part of your IB view.
Each of the four spacing constraints should show a number equal to the distance of your text view from the container window. If you aligned them, this number should be either 0 or -1. Click the down arrow for each of them and select "Use Current Canvas Value". Do it for all four. Make sure no other constraints are selected.
Click on "Add constraints" on the bottom of the panel.
Run your project. Your textview should resize with the window.
Also, as Jay's comment mentions, make sure you do not have any "leftover" constraints in your view. You can check this either by observing Xcode's warnings, or manually by inspecting your view's constraints by going to the Size Inspector tab (4th tab on the Utilities bar).
If you need to have your textview arranged in a more complex layout, it might be worth taking a look at the AutoLayout Guide.
I'm working on some updates to my first Mac app and I'm trying to get my window's toolbar buttons to look like the toolbar buttons on EVERY standard Mac app. However, for the life of me, I can't find a button type or a barbutton type that gets me what I'm looking for. Am I missing something?
Here is an image showing several Mac apps (Preview, Finder, and Safari) with toolbars at the top which have very-slighty rounded corner buttons which also have a slight gradient on them, etc.
However, in my .xib I've got a toolbar and I've dropped every kind of button I can find on the thing and nothing looks like the standard Mac button.
The first button looks pretty close, but it's clearly not the same color. Am I missing something?
#Matt Ball is right - you can use NSSegmentedControls, even for single one-time click buttons. Just set the number of segments to 1, and set the mode to "Select None".
One of my shipping apps uses this technique, see below:
All of the controls there are NSSegmentedControl, including the single one.
Update: there are a few standard button icons which are meant for toolbars. The NSImage Class Reference has a list.
In the above screenshot, only two of the buttons are using built-in images: NSLeftFacingTriangleTemplate, and NSRightFacingTriangleTemplate. The others I drew myself.
