iPhone5 图标变大

[zhanglichuan]

模拟器和真机都会这样，iPhone5、iOS10，iPhone6以上都不会

- (void)tabBarController:(UITabBarController *)tabBarController didSelectControl:(UIControl *)control {
    UIView *animationView;
    if ([control cyl_isTabButton]) {
        animationView = [control cyl_tabImageView];
    }

    // 即使 PlusButton 也添加了点击事件，点击 PlusButton 后也会触发该代理方法。
    if ([control cyl_isPlusButton]) {
        UIButton *button = CYLExternPlusButton;
        animationView = button.imageView;
    }
    [self addScaleAnimationOnView:animationView repeatCount:1];
}

//缩放动画
- (void)addScaleAnimationOnView:(UIView *)animationView repeatCount:(float)repeatCount {
    //需要实现的帧动画，这里根据需求自定义
    CAKeyframeAnimation *animation = [CAKeyframeAnimation animation];
    animation.keyPath = @"transform.scale";
    animation.values = @[@1.0,@1.2,@0.9,@1.1,@0.95,@1.02,@1.0];
    animation.duration = 1;
    animation.repeatCount = repeatCount;
    animation.calculationMode = kCAAnimationCubic;
    [animationView.layer addAnimation:animation forKey:nil];
}

pod 'CYLTabBarController' # 1.25.0

[zhanglichuan]

我在测试了，在iOS10.0中，好像都有这样的情况

[ChenYilong]

imageset设置有问题，四个值加起来要等于0，其它issue讨论过

[zhanglichuan]

好的，已经可以的，

• top + bottom == 0
  • left+right == 0

才可以，谢谢
