Usage

Designated Initializer

Use the designated initializer below to initialize the circle menu:

// |buttonCount| : count of buttons around (1<= x <=6)
// |menuSize| : size of menu
// |buttonSize| : size of buttons around
// |buttonImageNameFormat| : name format for button image
// |centerButtonSize| : size of center button
// |centerButtonImageName| : name for center button image
// |centerButtonBackgroundImageName| : name for center button background image
- (id)      initWithButtonCount:(NSInteger)buttonCount
                       menuSize:(CGFloat)menuSize
                     buttonSize:(CGFloat)buttonSize
          buttonImageNameFormat:(NSString *)buttonImageNameFormat
               centerButtonSize:(CGFloat)centerButtonSize
          centerButtonImageName:(NSString *)centerButtonImageName
centerButtonBackgroundImageName:(NSString *)centerButtonBackgroundImageName;

Button Action

Override the -runButtonActions: message to customize your button action:

- (void)runButtonActions:(id)sender {
  [super runButtonActions:sender];

  // Do buttons' action appropriately by |[sender tag]|
  // ...
}

Tags are defined like below:

TAG:        1       1   2      1   2     1   2     1 2 3     1 2 3
           \|/       \|/        \|/       \|/       \|/       \|/
COUNT: 1) --|--  2) --|--   3) --|--  4) --|--  5) --|--  6) --|--
           /|\       /|\        /|\       /|\       /|\       /|\
TAG:                             3       3   4     4   5     4 5 6

Navigation Bar

The default case is that the navigation bar is only shown in child views. If you want it to be shown with the circle menu together, add the macro below

#define KY_CIRCLEMENU_WITH_NAVIGATIONBAR 1

to your constatns.h or config.h, or any other files that are imported in your <Project>-Prefix.pch.

KYArcTab

Arcuated tab view controller with toggleing animation, 2 ~ 4 tabs are enabled. What's more, you can swipe left or right to toggle the views.

Usage

Subclass KYArcTabViewController and override the -setup message to configure the child view controllers.

Then use the designated initializer below to initialize the tab view controller when you need:

- (id)  initWithTitle:(NSString *)title                // title
           tabBarSize:(CGSize)tabBarSize               // size of tab bar
tabBarBackgroundColor:(UIColor *)tabBarBackgroundColor // background color of tab bar
             itemSize:(CGSize)itemSize                 // size of items on tab bar
                arrow:(UIImage *)arrow;                // arrow on the tab bar
