How to make transparent background for the whole application?
I have such settings for the main view:
But I still get non transperent background on the device
Put a bgView behind your desired view(original view), Set your original view background to clear color. Make bgView background color black and set alpha as desired.
EDIT:
If you meant to make the whole app transparent and show the device wallpaper as bg, then I am pretty sure its not possible.
For Transparency..
*) check Opaque off
*) change alpha depending on yur need.

My App has a white background UIWindow.backgroundcolor. When I rotate the device the white background rotates on black background.
Is it possible to change the background behind that window?
I would like to have all white. Any ideas? Thanks in advance.
You cannot change the black color as it is actually not a part of the app. What you can do in this case is add a very large (somewhat larger then the screen size) root view and center it. Then place everything else into this view. This way when your app changes orientation the large view will also rotate, but because of it's size it's edges will never reach the screen and the black color will remain hidden.
I've run into an interesting situation with a UIWebView. In Interface Builder, I set all four constraints to equal the margins and filled the webview with content. It works exactly as you'd expect.
An issue occurs when I rotate the webview. The webview rotates but in doing so, it reveals an grey background color. This isn't a color that I've set. In fact, I set the parent's view to have a black background color to match the webview content.
Here are my constraints for reference:
I'd appreciate any guidance on how to make my webview will the entire border or at least, manually change the grey color. Much thanks!
Note: This only occurs in the simulator. I haven't tried this on a device yet.
Ack ... it was the background view that was the culprit. The simulator didn't pick up my color changes. I never did a clean on them. I tested today and was able to change the grey color to the one of my choosing.
I would like to know how to change the keyboard background color programmatically in iOS? The background is normally grey but I need clear background color (behind letters).
There are no direct properties which would let you do that. One option is to create a custom inputView
Another is to get all the views from the key window, find the view for the keyboard and make changes. But this is not advisable and can break at any point.
I'm trying to add a beige color to the bounce white space area that appears when dragging this WebView off screen. I've tried setting the WebView and WebView.ScrollView background colors manually and also setting them to transparent with opaque set to false having the ViewController's view background color set to beige - no luck. I also read in some of the objective-C iOS threads that adding a SubView with the background color I want to the WebView would do the trick, but could not get this to work in Mono.
The background of the Web content has been set in the HTML code of the document.
I wish I could post an example image, but don't have 10 rep yet. Feel free to ask for a better description.
Can anyone shed some light on how to accomplish this?
I set the background colour of my webView to clearColor in my nib file and for me it works fine:
Let me know if it still doesn't work for you.
I have a view with a background color. How to re-size the background color when the view change its size? My problem is even if the view is bigger, the background color size still the same size.
I had the same problem. I thought I had.
When device have rotated, background (background colour) didn't have change its size.
At least it looked as background colour's size didn't change.
I had feeling the situation is stupid. Size of background colour, but not of background? What? I said I felt being mad. But everything looked like background colour keeps it's size despite of device rotation.
I am writing this in attempt to help developers who will google for answer in same circumstances.
Background colour is not separate view, it is a part of its view, so it is absolutely impossible for background colour to have size other than size of its view. Scrutinise hierarchy of your view. You must have some subviews which make you think your background doesn't change size.
NSLog(#"%#", [self.view recursiveDescription]); // compiler will warn it doesn't know method recursiveDescription, it doesn't matter.
// TODO: remove line above from production code if you don't want to be rejected!
will log view's hierarchy of your view controller.
