iPhone ProgressBar

Question

How can I change the color as well as size of UIProgressBar in iPhone SDK

Answer 1

Assuming you mean a UIProgressView, you can resize it as you would any other view, by setting the frame:

UIProgressView *progressView = [[UIProgressView alloc] initWithProgressViewStyle:UIProgressViewStyleBar];
[progressView setFrame:CGRectMake(0,0,320,10)];

or if you're using the default style, you can set the frame in the init method:

UIProgressView *progressView = [[UIProgressView alloc] initWithFrame:CGRectMake(0,0,320,10)];

As far as I know, the color of a UIProgressView cannot be changed. You'll probably have to roll your own view for that.
