1:創(chuàng)建繼承于UITabBar的類MyTabBar
2:設(shè)置代理實(shí)現(xiàn)UITabBar的代理協(xié)議
@protocol?MyTabBarDelegate
- (void)tabBarDidClickCenterButton:(XPFTabBar *)tabBar;
聲明代理
@property?(nonatomic, weak) id delegate;
3:在.m初始化方法重寫
- (nonnull instancetype)initWithFrame:(CGRect)frame {
? ? if (self = [super initWithFrame:frame]) {
? ? ? ? UIView * backView = [[UIView alloc]init];
? ? ? ? backView.backgroundColor = [UIColor whiteColor];
