Question

Is this a UIButton? If it is, how is the background red done? Obviously, it is not
red UIColor? Is there same tool or utility included with Xcode to allow making buttons
like this?

Answer 1

You can generate similar buttons with private class UIGlassButton.
I saw it first here http://pastie.org/830884 by @schwa.

Run an app with this code in your iOS simulator to create a custom button (or in the device, save to $(APP)/Documents and enable iTunes file sharing).

Class theClass = NSClassFromString(@"UIGlassButton");
UIButton *theButton = [[[theClass alloc] initWithFrame:CGRectMake(10, 10, 120, 44)] autorelease];
// Customize the color
[theButton setValue:[UIColor colorWithHue:0.267 saturation:1.000 brightness:0.667 alpha:1.000] forKey:@"tintColor"];
//[theButton setTitle:@"Accept" forState:UIControlStateNormal];
[self.view addSubview:theButton];

UIGraphicsBeginImageContext(theButton.frame.size);
CGContextRef theContext = UIGraphicsGetCurrentContext();
[theButton.layer renderInContext:theContext];

UIImage *theImage = UIGraphicsGetImageFromCurrentImageContext();
NSData *theData = UIImagePNGRepresentation(theImage);
[theData writeToFile:@"/Users/<# your user #>/Desktop/button.png" atomically:NO];
UIGraphicsEndImageContext();

Once you obtain the png, use it as button background.

Alternatively, you can build the buttons programmatically (by Jeff Lamarche).
