How can I determine UITabBarItem position?

Question

如何确定UITabBarItem是否具有标题“ Hello”且位置为0？

Answer 1

我宁愿让使用项目的索引indexOfObject上tabBar项目数组：

NSUInteger index = [tabBar.items indexOfObject:item];

Answer 2

Use the items property of the UITabBar, like:

if([[myTabBar items] indexOfObject:myTabBarItem] == 0)
{
  UITabBarItem* theItem = [[myTabBar items] objectAtIndex:0];

  if([theItem.title isEqualToString:@"Hello"])
  {
    // it's in position 0 and has title "Hello"
  }
}

Answer 3

uitabbaritem继承自uibaritem，后者定义了标签和标题属性。
