There is an abundance of interesting code in the project, including numerous block animations. Many of the little things Sam has already dialed in – for example, the size of an HUD is dynamically adjusted when displaying text, the longer the text, the wider the view (and support for wrapping text works out of the box).

Below are a few screenshots, the first shows a long message that is wrapped to fit the display:

The images below show two of the options for dismissing messages, one for successful operations, one for error conditions:

The images below show the basic idea, however, you owe it to yourself to download and run the demo project to get the full effect.

And the best part of integrating the transition into your project, the code is as simple as shown below:

MFDoorwayTransition *transition = [[MFDoorwayTransition alloc] 
   initWithBaseView:self.view
   firstView:self.currentView 
   lastView:self.nextView];
[transition buildAnimation];
[transition release];

The demo project included shows how OBShapedButton differs from a standard button, as the figure below indicates:

OBShapedButton also supports complex image shapes:

As James Tang, the author points out, the control is in early development and is essentially a work in process/demo. However, with some additional coding, I think this could be a very nice control to display and manage content on a small screen (the iPhone).

Below is a screenshot of the demo application included with the project that shows a “revealed” view and the sidebar on the right.

In the screenshot above, the top progess view has an outer color of cyan and an inner color that is blue. The second bar has an outer color that is defined as [UIColor clearColor]], an inner color that is light gray and empty color that is white.

The example included with DDProgressView – which is the basis of the screenshots above – demonstrates how to create two controls, set their color values and update the progress indicator using an NSTimer with a scheduled timer interval.

You can also use section headers within the table, as shown below:

As described on github, the features include:

- Multiple and single selection of cells.
- Supports orientation change.
- Easy to customize, access UITableView and UIAlertView via properties.
- Supports sections and custom section headers.

This is a very creative use of an alert, thanks Simon Blommegård for creating this control.

Take a look at the screenshot on the left below, I’ve pressed the spacebar to enable DCIntrospect and tapped on the circle image in the upper right. Notice the information displayed for the UIImageView across the top where the status bar was previously shown, including the view size and location on screen. With a few keystrokes I can move and resize the image, as shown in the screenshot on the right.

As another example, in the screen below on the left , all views are outlined:

When DCIntrospect is active, you use hotkeys to invoke various operations such as moving views, logging, etc. The screenshot, above right, is the help screen listing the default hot keys and their actions – you can change the key bindings by editing an included configuration file.

As one who has always coded my user interfaces the old fashion way (sans Interface Builder), DCIntrospect is an intriguing tool, offering an inside look at layout information that is not easily accessible while running an app. There are many interesting features in DCIntrospect – take the demo project for a test drive, if nothing else it’s interesting to see layout information displayed in real time within an app.

Notice in the screenshot below that the tabbar on top has no icons, whereas the tabbar on the bottom has both icons and text. With a simple code change, you can also have only icons and no text.

The goal of Nimbus is quite admirable: Nimbus hopes to one day provide as much value as Three20 does on a feature-by-feature comparison, but with the invaluable benefit of sublime documentation and test coverage.

What You’ll Find in Nimbus

- Launcher offers an icon-centric UI
- Asynchronous image downloading and caching
- Photo scrolling viewer with zoom support
- Table-based form elements
- Many other helpful controls

Below is a screenshot of the support for tables and form elements as well the launcher UI. Both apps are included in the example set packaged with Nimbus.

Tapku includes a fair amount of code, from UI controls (coverflow, heads up display, background image downloading…) to a nice selection of category extensions for NSString, NSDate among others.

The screenshots below, from the demo universal application, show the graph and coverflow UI effects in Tapku:
