Many thanks to @ZevEisenberg

MRoundedButton

MRoundedButton is a subclass of UIControl and the appearance is like the iOS 7 Phone app button or the button on the Control Center and also perform fade in/out animation for touch event.

Four button styles are suplied:

MRoundedButtonDefault           //  central text
MRoundedButtonSubtitle          //  text with subtitle 
MRoundedButtonCentralImage      //  central image
MRoundedButtonImageWithSubtitle //  image with subtitle

To set a transparent border:

MRoundedButton *button = [[MRoundedButton alloc] initWithFrame:#<BUTTON_FRAME>
                                                   buttonStyle:#<BUTTON_STYLE>];
button.borderWidth = 2;
button.borderColor = [UIColor clearColor];

The value of borderWidth and cornerRadius are limited to MIN(BUTTON_WIDTH / 2, BUTTON_HEIGHT / 2). Setting the cornerRadius to FLT_MAX or MRoundedButtonMaxValue can easily make a round button.

MRoundedButtonAppearanceManager

MRoundedButtonAppearanceManager is the appearance manager for MRoundedButton, each appearance information can be stored in a NSDictionary object to make it reusable in the whole project:

NSDictionary *appearanceProxy = @{kMRoundedButtonCornerRadius : @40,
                                  kMRoundedButtonBorderWidth  : @2,
                                  kMRoundedButtonBorderColor  : [UIColor clearColor],
                                  kMRoundedButtonContentColor : [UIColor blackColor],
                                  kMRoundedButtonContentAnimationColor : [UIColor whiteColor],
                                  kMRoundedButtonForegroundColor : [UIColor whiteColor],
                                  kMRoundedButtonForegroundAnimationColor : [UIColor clearColor]};
[MRoundedButtonAppearanceManager registerAppearanceProxy:appearanceProxy1 forIdentifier:#<UNIQUE_IDENTIFIER>];

MRHollowBackgroundView

MRHollowBackgroundView can be used to place the MRoundedButton on an image view or something.

In the drawRect: method, each subview of HRHollowView will be cliped to its bounds by CGContextEOFillPath(). Then the superview can be displayed from the hollowed shapes.
