问题描述
我有一个这种结构的xib：
I have a xib with this structure:
- Tab Bar Controller
-- Tab Bar
-- NavigationController
--- Navigation Bar
--- News List View Controller
---- Navigation Item
--- Tab Bar Item
-- NavigationController
--- Navigation Bar
--- News List View Controller
---- Navigation Item

[...]
如何编写循环以在每次迭代中获取每个UIViewController（新闻列表视图控制器）？
How can I code a loop to take each UIViewController (News List View Controller) in each iteration?
推荐答案
像这样以代码方式访问它们：
Access them codewise like this:
NSArray * controllerArray = [[self navigationController] viewControllers];
for (UIViewController *controller in controllerArray){
//Code here.. e.g. print their titles to see the array setup;
NSLog(@"%@",controller.title);
}
