I am unable to find the way to hide a UIbarButtonItem set on a toolbar. The button is properly declared and linked on IB. However the following line does nothing,  self.botoVolver = nil;

I would like to dynamically hide a button in one of my views depending on a certain condition.  I tried adding some code to the view controller's -viewWillAppear method, to make the button hidden before displaying the actual view, but I still don't know how to do that.  I have a reference to the button through an IBOutlet, but I'm not sure how to move forward from here. For reference, this is a UIBarButtonItem instance.

I've been a .NET developer for several years now and this is still one of those things I don't know how to do properly. It's easy to hide a window from the taskbar via a property in both Windows Forms and WPF, but as far as I can tell, this doesn't guarantee (or necessarily even affect) it being hidden from the Alt+↹Tab dialog. I've seen invisible windows show up in Alt+↹Tab, and I'm just wondering what is the best way to guarantee a window will never appear (visible or not) in the Alt+↹Tab dialog.  Update: Please see my posted solution below. I'm not allowed to mark my own answers as the solution, but so far it's the only one that works.  Update 2: There's now a proper solution by Franci Penov that looks pretty good, but haven't tried it out myself. Involves some Win32, but avoids the lame creation of off-screen windows.

In macOS Sierra, it used to be Command + Shift + .. But that does not appear to work in macOS Mojave. Has something changed?  What is the keyboard shortcut to show/hide hidden files in Finder without restarting in macOS Mojave?

How do you add that little "X" button on the right side of a UITextField that clears the text?  I can't find an attribute for adding this sub-control in Interface Builder in the iPhone OS 2.2 SDK.  Note: In Xcode 4.x and later (iPhone 3.0 SDK and later), you can do this in Interface Builder.

I have my Win 7 taskbar set to autohide but its often pops up... and just stays visible, obscuring the bottom of all other programs (since they are behaving correctly (as if the Task Bar isn't there b/c it's supposed to autohide).  Any way to force it to HIDE again?

I thought there was a checkbox to suppress the hiding of my user Library folder on Mavericks, but I can't seem to find it. I appreciate hiding Library by default, but  have missed it being easily accessible.  How can I get the library folder to be visible in Finder, the Finder go menus / file save dialogs without needing to hold down shift?

In several cases I want to add a toolbar to the top of the iPhone keyboard (as in iPhone Safari when you're navigating form elements, for example).    Currently I am specifying the toolbar's rectangle with constants but because other elements of the interface are in flux - toolbars and nav bars at the top of the screen - every time we make a minor interface change, the toolbar goes out of alignment.  Is there a way to programmatically determine the position of the keyboard in relation to the current view?

Will there be a way to disable auto-hide behavior of global application menu in Unity. While I would prefer to have this behavior disabled by default (as it is bad UX), it looks like it's here to stay, so I'm wondering if, as a user, I will be able to turn it off.

I've configured my touch bar to always show function keys in one program where I use those frequently (IntelliJ IDEA, code editor). Many hotkeys in IDEA are triggered using a function key together with shift, alt or control, e.g. for renaming a variable, I use Shift+F6.  With the emulated function keys, this does not work, the program acts as if I had just hit F6 without holding down the alt key.  It was no problem with the hardware function keys on my old MacBook.  Is this a known bug, or a limitation one has to live with? Or is there some way to work around it? Perhaps I'm just to stupid and missing something obvious?  This is a major pain for me as a software developer…

In my plugin I have an operator that needs to iterate through potentially 100's of objects that might be 'hidden in viewport' or 'disabled in viewport' and perform some operations  that require the object to be visible in viewport. Afterwards I want to restore whatever visibility the object had, so I need to both get and set these options.  IE, get/set the status of these. When I hover over the icons, both show the parameter bpy.context.object.hide_viewport. Obviously they can't both be the same parameter as they both do different things. How do I get and set 'hidden in viewport' and how do I get and set 'disabled in viewport' using the Python API? Edit: I can see that both ObjectBase(bpy_struct) and Object(ID) have the hide_viewport property, however ObjectBase is documented as 'Temporarily hide in viewport' and Object is documented as 'Globally disable in viewports'. How do I access an Object's ObjectBase?

I don't like the auto hide launcher for it is too annoying for me. The launcher stays hidden and to reveal it, the mouse pointer has to be moved to the default hot spot. I'd instead like to have the hide to dodge windows previously available in Ubuntu 11.10. How do I change back to this behaviour?

How do I create a button on my taskbar along with the time and stuff that performs a specific task? I wanted to be able to disable and enable my keyboard with the help of a keyboard shortcut, but I realized that once I disabled my keyboard with a shortcut, I wouldn't be able to use the keyboard to enable it again. So, I want a button on my taskbar that does this for me with the click of a button, thus not requiring my keyboard. Thanks.
