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 borderWidth and cornerRadius are limited to MIN(BUTTON_WIDTH / 2, BUTTON_HEIGHT / 2). So if you want to make a Round MRoundedButton, just set the cornerRadius to FLT_MAX

MRoundedButtonAppearanceManager

MRoundedButtonAppearanceManager is the appearance manager for the MRoundedButton, each appearance information can be stored in an NSDictionary object with a unique identifier:

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>];

MRHollowView

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

In the drawRect: method, each subview of HRHollowView are EO cliped to its bounds. Then the superview content can be displayed via the hollowed shapes.

TODO

1. Make it Cocoapods
2. Fix typo (may need your help)
3. Border issue
