- 在Appdeleagte中加入这句话,虽然没有抖动了,但是会造成UI布局问题
[[UITabBar appearance] setTranslucent:false];
2.自定义TabbarView,继承UITabbarView,添加以下方法,亲测有效
CG_INLINE BOOL
OverrideImplementation(Class targetClass, SEL targetSelector, id (^implementationBlock)(Class originClass, SEL originCMD, IMP originIMP)) {
Method originMethod = class_getInstanceMethod(targetClass, targetSelector);
if (!originMethod) {
return NO;
}
IMP originIMP = method_getImplementation(originMethod);
method_setImplementation(originMethod, imp_implementationWithBlock(implementationBlock(targetClass, targetSelector, originIMP)));
return YES;
}
+ (void)load {
static dispatch_once_t onceToken;
dispatch_once(&onceToken, ^{
if (@available(iOS 12.1, *)) {
OverrideImplementation(NSClassFromString(@"UITabBarButton"), @selector(setFrame:), ^id(__unsafe_unretained Class originClass, SEL originCMD, IMP originIMP) {
return ^(UIView *selfObject, CGRect firstArgv) {
if ([selfObject isKindOfClass:originClass]) {
// 如果发现即将要设置一个 size 为空的 frame，则屏蔽掉本次设置
if (!CGRectIsEmpty(selfObject.frame) && CGRectIsEmpty(firstArgv)) {
return;
}
}
// call super
void (*originSelectorIMP)(id, SEL, CGRect);
originSelectorIMP = (void (*)(id, SEL, CGRect))originIMP;
originSelectorIMP(selfObject, originCMD, firstArgv);
};
});
}
});
}
