Contrainer View storyboard 能拖出来的控件，继承UIView，当又与UIStackView 不一样，很奇葩的东西。
注1：可以直接拖入某个ViewController，并且可以多个！每一个对应连接了一个VC，相当于add childViewController了！
注2：链接有segue，但是不能直接用会崩溃，也不知道该怎么用才好。
注3：现在只能遍历自身的childViewControllers，然后去切换，感觉并没有纯代码方便啊，阿西吧。
// 找到对应的 childViewController（总觉得哪里不对！！！！）
- (void)checkChildViewController {
[self.childViewControllers enumerateObjectsUsingBlock:^(__kindof UIViewController * _Nonnull obj, NSUInteger idx, BOOL * _Nonnull stop) {
if ([obj isKindOfClass:[AViewController class]]) {
self.avc = obj;
}
else if ([obj isKindOfClass:[BViewController class]]) {
self.bvc = obj;
}
else if ([obj isKindOfClass:[CViewController class]]) {
self.cvc = obj;
self.currendViewController = obj;// 最后一个拖进去的 container View 是当前的
}
else {
// if more vc
}
}];
}
// 切换
- (void)transitionToViewController:(UIViewController *)destinationViewController {
if (destinationViewController == self.currendViewController) {
return;
}
[self transitionFromViewController:self.currendViewController toViewController:destinationViewController duration:CGFLOAT_MIN options:UIViewAnimationOptionCurveEaseOut animations:^{
} completion:^(BOOL finished) {
self.currendViewController = destinationViewController;
}];
}
顺便贴个纯代码的
self.viewControllers = @[self.detailViewController,
self.performanceViewController,
self.relatedDocumentViewController,
self.similarProductViewController,
self.productAboutViewController];
- (void)addChildViewControllers {
int temp = 0;
for (UIViewController *viewController in self.viewControllers) {
[self addChildViewController:viewController];
[viewController didMoveToParentViewController:self];
viewController.view.frame = self.contentView.bounds;
if (temp == 0) {
[self.contentView addSubview:viewController.view];
self.currentViewController = viewController;
}
temp ++;
}
}
- (void)transitionViewControlleToIndex:(NSInteger)index {
if (index >= self.viewControllers.count) {
return ;
}
UIViewController *transitionedController = self.viewControllers[index];
if (transitionedController != self.currentViewController) {
[self transitionFromViewController:self.currentViewController
toViewController:transitionedController
duration:CGFLOAT_MIN
options:UIViewAnimationOptionCurveEaseInOut
animations:^{
//
} completion:^(BOOL finished) {
self.currentViewController = transitionedController;
}];
}
}
