Is there an iPhone Class which i开发者_JAVA技巧mplements a nice looking progress bar which is a bit taller and more customizable than the built-in one? I'm looking for something that would look like this:

There isn't an easy way to alter the UIProgressView, but you could use a UISlider. This will allow you to set images for the two ends and the thumb image with - setMaximumTrackImage:forState:, - setMinimumTrackImage:forState:, and - setThumbImage:forState: respectively.

You can then update the slider value with – setValue:animated: and get the visualization that you want.
