I have a monotouch project and I am trying to theme the uipicker without any luck. I have tried setting backgroundcolors to clear however none seem to do much.
To start with I don't want to do anything to difficult I really just want to be able to clear the black background then remove the 2 tone gradient bar that the picker is inside.
Any monotouch gurus care to lend a hand?
It is not an easy task (Apple doesn't have a clear cut way to do this). Read some of the options here.
So you can either:
Create an image with a transparent center to add a UIImageView as a subview,
Try settings properties on a Subview of UIPickerView
Try porting their IXPickerOverlayView to MonoTouch

As far as I know, there is no way to rotate a UITabBarController on its side. However, you could take a UITabView (https://developer.apple.com/documentation/uikit/uitabbar) and rotate it on its side using Core Animation. To add functionality, set something as the UITabBar's delegate to learn about changes.
As far as an actual code snippet, I typically write in Swift, but I found another Stack Overflow answer with what you're looking for.

I am developing a Cocoa Application for Mac OSX. I intend to have multiple NSScrollViews and I'd like all of them to scroll at the same time if one of them is selected and scrolled.
I saw for UIScrollView there is a method "scrollViewDidScroll" that I could do this with an iPhone application.
Is there anything similar for NSScrollView or a way to go about doing this? Any help would be greatly appreciated.
Your solution is going to require that one of the scroll views will need to receive notifications that the other scroll view is being scrolled.
Apple actually provides some very nice documentation on Synchronizing Scroll Views, which also has some sample code snippets as part of it.
I designed a web app for iPhone and am now trying my hands at a native Objective-C version, and I'd like to retain some continuity with my original design. Since my web version uses CSS, I was able to customize the color palette, even though the UI was designed to imitate a native iPhone UI. I'd like to use a similar color scheme for my native app, but it doesn't seem so easy out of the box. I've gone through a couple tutorials and played around a bit with Interface Builder, inspecting the individual settings available for each control. My biggest questions are:
Is it possible to (or how do I) change the color of a Round Rect Button?
Is it possible to (or how do I) change the color of cells in a Table View?
Where in the Cocoa Touch Library can I find the standard iOS UI buttons, e.g. the green "Call Back" and red "Delete" buttons in the native voice mail?
Thanks
Nope, I don't think so. And you probably shouldn't anyways. In my opinion it's better to rather stay consistent with the OS and not the web... What you can do is to use a custom image.
UITableViewCell has a property named backgroundView, which is only present if you have a grouped style. This view has -- just like every other view -- a background color. If you don't have this and want to color individual cells, build a custom cell where you put in a view as background view.
As far as I know, they are not publicly available. However, you may find a lot of template images etc on the web that you can use.
Please see the youtube:

notice that the 0:35 , the iPad bottom have a thin photo bar. Is it a private API or I need to create my own or Which UI Element will it be? Thz.
That's definitely a custom job. However, it's basically a UIToolbar with a fancy slider on it. You can easily make the toolbar using Interface Builder, and you could take a simple stab at the slider by taking a regular UISlider and giving it some replacement images for its track, thumb, etc. See the documentation on UISlider.
If that doesn't quite work, then you're going to have to get down and dirty in UIControl code and make on yourself from scratch (or hope and pray that someone has written an open source version already).
