Progress bar for iPhone Customization

Progress bar for iPhone Customization

Train of Thought: instead of inheriting uiprogressview, It inherits uiview and adds two uiimageviews. One is a back image, and then adds a fill image to it and sets the X coordinate to the leftmost of the screen, then, a timer changes the X coordinates of the fill graph at intervals to achieve the effect similar to the progress.
