Question

我正在尝试将自己的图像设置为UITabBarItem上的选定图像和未选择图像，但没有运气。我在视图控制器viewDidLoad和viewWillAppear方法中尝试了以下代码，但都不起作用：

[self.tabBarItem setFinishedSelectedImage:[UIImage imageNamed:@"on_rojo"] withFinishedUnselectedImage:[UIImage imageNamed:@"on"]];

我做错了什么？我也读过：iOS 5: UITabBarItem setFinishedSelectedImage:withFinishedUnselectedImage: not working / ignored，但我在IB上创建了我的UITabBarController，而不是以编程方式创建。这是问题吗？

提前谢谢你，

您必须为每个标签项指定图像。以下代码适用于我

if ([[tabBarController.tabBar.items objectAtIndex:0] respondsToSelector:@selector(setFinishedSelectedImage:withFinishedUnselectedImage:)]) {

  [[tabBarController.tabBar.items objectAtIndex:0] setFinishedSelectedImage:[UIImage imageNamed:@"blabla1.png"] withFinishedUnselectedImage:[UIImage imageNamed:@"bleble1.png"]];
  [[tabBarController.tabBar.items objectAtIndex:1] setFinishedSelectedImage:[UIImage imageNamed:@"blabla2.png"] withFinishedUnselectedImage:[UIImage imageNamed:@"bleble2.png"]];
  [[tabBarController.tabBar.items objectAtIndex:2] setFinishedSelectedImage:[UIImage imageNamed:@"blabla3.png"] withFinishedUnselectedImage:[UIImage imageNamed:@"bleble3.png"]];
  [[tabBarController.tabBar.items objectAtIndex:3] setFinishedSelectedImage:[UIImage imageNamed:@"blabla4.png"] withFinishedUnselectedImage:[UIImage imageNamed:@"bleble4.png"]];

}
