使用分段控件切换集合视图

Question

在iOS上，使用位于导航栏中的分段控件切换集合视图的正确/最有效方法是什么？

Answer 1

What you mean by switching? Actually you can use a single collection view and change the data source of the collection according to the switch value

Add an action for your segmented control to change the data source

- (IBAction)changeCollectionViewData:(UISegmentedControl*)sender {

switch (sender.selectedSegmentIndex) {
    case 0:
        self.images =self.cars // displays images of cars;
        break;
    case 1:
        self.images =self.bike // displays images of bikes;
        break;
}
[self.collectionView reloadData]

}  
// self.images is the data source array  

Remember you need to set the numberOfItemsInSection accordingly
