KBRoundedButton

allows you to create beautiful rounded rect button with dynamic colors and activity indicator, completely in Interface Builder.

Button's corners alre always rounded to half of it's height.

Installation

KBRoundedButton is available via CocoaPods. To use it in your app simply add:

pod 'KBRoundedButton'

Setting colors

You can set colors for each state of the button in both code and Interface builder. Both background colors and title colors are supported. Set of colors:

@property (nonatomic, strong) UIColor *backgroundColorForStateNormal;
@property (nonatomic, strong) UIColor *backgroundColorForStateSelected;
@property (nonatomic, strong) UIColor *backgroundColorForStateHighlighted;
@property (nonatomic, strong) UIColor *backgroundColorForStateSelectedAndHighlighted;
@property (nonatomic, strong) UIColor *backgroundColorForStateDisabled;

@property (nonatomic, strong) UIColor *titleColorForStateNormal;
@property (nonatomic, strong) UIColor *titleColorForStateSelected;
@property (nonatomic, strong) UIColor *titleColorForStateHighlighted;
@property (nonatomic, strong) UIColor *titleColorForStateSelectedAndHighlighted;
@property (nonatomic, strong) UIColor *titleColorForStateDisabled;

Setting them in IB is very easy: all you have to do is to set a class of your button to KBRoundedButton and User Defined Runtime Attributes for a subset of properties from above.

Colors are set by creating an UIImage of 1x1 size in given color and placing it as a backgroundImage of button.

Setting shadow

KBRoundedButton has a property

@property (nonatomic, assign) BOOL shadowEnabled;

which can be also set in IB and enables bottom shadow for a button. Due to the fact that internal implementation uses CALayer's cornerRadius property altogether with clipsToBounds it was unable to use native shadow. Method

- (void)addBottomShadow

creates a separate view with size of the button and places it below the button in view hierarchy.

Activity Indicator

KBRoundedButton's last property

@property (nonatomic, assign) BOOL working;

displays activity indicator when set to YES and restores original title when set to NO. See Log in button for a realtime example.
