I'm working on a project that has given me MapView.xib, MapViewController.h, and MapViewController.m.
The .xib has two buttons, which are controlled in the .h and .m files. I need to create separate controller files (ExtendedMapViewController.h and ExtendedMapViewController.m) that will contain methods that control 2 more items in the MapView.xib (a segmented control that can change the map's type, and a button that will hide and show the segmented control).
I cannot figure out how to assign the IBActions to the segmented controller or the second button. Is this even possible to do? I'm fairly new to Obj-C, so even a hint in the right direction would be appreciated.

Good afternoon everybody.
Let me better explain the situation.
In a myComp.html I got the instance of some dropdown-buttons from another component <app-myButtonsFromAnotherComponent></app-myButtonsFromAnotherComponent>.
The dropdown-buttons are being displayed correctly BUT when I try to get the script which they are originally connected myButtonsFromAnotherComponent.ts they do not seem to communicate at all with it (I am using a Getter function in the .ts but it doesn't retrieve the datas) and at the same time, because of the instance, I cannot access their values from myComp.html either, I can just display the buttons on the screen and display the values through {{theValueInQuestion}} int their original HTML file.
Can anyone, please, help me to get those values and use them in my script?
PS Why "reusable" in the title? Because in such a way I can keep those buttons in a separate component and let other components grab them without copy and paste a ton of code.
They are two separate components you need a way to communicate between components.
you can look more into :
Localstorage
Output() and EventEmitter
Parent to Child via Input
In my application I have some modules which should have the possibility to upload images.
I created a child component for handling the image uploading, for easy reuse.
The problem is when I upload image from one of the child components it is always displayed in the first component instance.
I have replicated the issue here:

Anyone knows what the problem is?
Both of your file inputs have the same id, so when you click the second label, it refers back to the first input. Try generating a dynamic id for each input and that should do the trick.
I am using doxygen to generate an API document for my project written in pure C. I want to have a left side frame in the index.html generated by doxygen. So I enabled the option "GENERATE_TREEVIEW" in Doxyfile, but I am not satisfied with its layout.
I want a brief tree layout, not like this :
Files
File List
File Members
All
Functions
I have only one file to export, so I don't need "File List".
I have only functions to export(no variables, class etc.), so I don't need "File members".
And, the most reason I want to customize is that I want to classify my API into several different sub-class. Just like this:
Cursor Operation
vi_h()
vi_j()
vi_k()
vi_l()
Text Edit
vi_dw()
vi_dd()
Text Search
vi_f()
vi_F()
But doxygen seems doesn't provide a way to customize the side frame.
I have thought about another way: give up side frame, and use an category page, which can be accomplished using \section and #ref. But this is not good for readers, because every time they click, they have to switch to another web-brower tab, slow and inconvenient.
I am currently using the Views and Display Suite modules to create a page that works as an image gallery. You click on the menu button to take you to a page (the view) that has multiple links to nodes (individual galleries).
When you click these nodes, they take you into the separate page and show all images uploaded using the "event" content type that I made.
The event content type has one field (type: image) that uses a multiupload widget, allowing for multiple file uploads.
However, the images on the node are displayed within divs, so they all have their own rows basically. I would like to know if it was possible to put them all into grids, and if so; how? I tried using display suite, but I only have that one field to work with.
If you want to get a fully customized page and arrange the fields just like you want, use the theme suggestions.
For a node of type "event", as you said, it would be node--event.tpl.php. You can duplicate the code inside the base template node.tpl.php of your parent theme (or if you don't have one, of Bartik for example) to have a good starting material.
Just rearrange the div, the tags, the variables as your convenience, add some custom CSS to make your grid, and you should be done!
I hope it helps.
I have a basic ASP.Net MVC 3 application which has a number of controllers and a number of actions (and subsequently views)
A common feature of the application is to show a pop-up dialog window for basic user input. One of the key features of this dialog process is a faded mask that gets shown behind the dialog box.
Each of these dialog window controls is in a separate Partial View page.
Now, some view pages may use multiple dialog boxes, and therefore include multiple partial views in them - which as is would mean multiple instances of the "mask" element.
What I am trying to find a solution for is to only need to create one instance of a "mask" element regardless of the number of dialog partial views I include, and then the script in each partial dialog will have access to this element (so basically it just needs to be on the page somewhere)
The only real idea I have come up with so far is to add the "mask" element to the master page (or in the original view page) and this will mean it only gets added once. The problem here is that it will be added even when it is not needed (albeit one small single element)
I can live with this, but I would like to know if there is a better way to handle these kinds of scenarios?
A quick idea that came to mind is some kind of master page inheritance hierarchy, So I may have a DialogMasterPage that inherits from the standard current master page. How does that sound for an approach?
Thanks
To do something like this, where each module can register their need for a certain thing in the master page, you can use HttpContext to store a flag of whether you need to write the mask div, and just set that property in each partial. At the end of the master page, if the flag is set, you can then write the mask div if its set to true.
Obviously to make this cleaner you could wrap it all in an HtmlHelper extension or something.
My initial thought is for you to use something like jQuery UI where it handles the masking for you or if you are using something custom you can load the content for the dialog via ajax then show it in the single dialog on the master page.
