How to display a progress indicator overlay/HUD on iPhone?

You can definitely overlap views. Just add the transparent overlay as a subview in the tableView From UIView's documentation: UIView objects are arranged within an UIWindow object, in a nested hierarchy of subviews. Parent objects in the view hierarchy are called superviews, and children are called subviews.

A view object claims a rectangular region of its enclosing superview, is responsible for all drawing within that region, and is eligible to receive events occurring in it as well. Sibling views are able to overlap without any issues, allowing complex view placement.

Interface Builder has been misleading me! I know that NSViews cannot overlap, and if you create overlapping UIViews in IB, it will flag them with warnings. Thank you for setting me straight.

You can save yourself some work by using the MBProgressHUD if it meets your needs.

Any object that lives in your MainWindow. Xib can get access to the application window via an outlet. The application delegate in the standard projects already has it, but you'll probably want to add the outlet to your view controller that needs to show the progress overlay.

Since in UIKit the UIWindow is a UIView (unlike NSWindow vs. NSView in Cocoa), you can simply add your progress view as a subview of the window: window addSubview:progressView; progressView will cover the entire application UI. This example uses the technique to fade out the Default. Png splash image: http://michael.burford.net/2008/11/fading-defaultpng-when-iphone-app.html With relation to the recent edit, as of MacOS X 10.5 Leopard NSView overlapping is deterministic (they always could overlap, you just got undetermined results), though it has a different front-to-back ordering depending on whether the containing view is layer backed or not.

This is most likely a side effect of integrating CALayers into the OS X view system.

Answer: Apples docs are pretty awesome. developer.apple.com/iphone/library/featu... Currently I'm into over laying transparent views (at least on the back of a napkin at this point). You can use them to hold menu buttons, move them in 3D space, just get nuts.

I mean is this a religious tract of or what? Amazing stuff from the guys at NEXT: UIView objects are arranged within an UIWindow object, in a nested hierarchy of subviews. Parent objects in the view hierarchy are called superviews, and children are called subviews.

I've just posted a HUD version of mine : https://github. Com/y0n3l/LGViewHUD you can get this result very easily : #import "LGViewHUD. H" .... LGViewHUD* hud = LGViewHUD defaultHUD; hud.

ActivityIndicatorOn=YES; hud. TopText=@"The longer...."; hud. BottomText=@"The better!"; hud showInView:self.

View; Once the task is ended, just invoke LGViewHUD defaultHUD hideWithAnimation:HUDAnimation and that's it!

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
