- (void)alertView:(LGAlertView *)alertView buttonPressedWithTitle:(NSString *)title index:(NSUInteger)index;
- (void)alertViewCancelled:(LGAlertView *)alertView;
- (void)alertViewDestructiveButtonPressed:(LGAlertView *)alertView;

@property (strong, nonatomic) void (^willDismissHandler)(LGAlertView *alertView);
@property (strong, nonatomic) void (^didShowHandler)(LGAlertView *alertView);
@property (strong, nonatomic) void (^didDismissHandler)(LGAlertView *alertView);
@property (strong, nonatomic) void (^actionHandler)(LGAlertView *alertView, NSString *title, NSUInteger index);
