KBRoundedButton: An Objective-C repository from mdziadkowiec

#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.
