Question

我正在尝试向tabViewController添加自定义图片。它对我来说很好;这是我正在使用的代码：

[[AppDelegate.Tabctrl.tabBar.items objectAtIndex:0] setFinishedSelectedImage:[UIImage imageNamed:@"Home-Select.png"] withFinishedUnselectedImage:[UIImage imageNamed:@"Home.png"]];
[[AppDelegate.Tabctrl.tabBar.items objectAtIndex:1] setFinishedSelectedImage:[UIImage imageNamed:@"MyTc-Select.png"] withFinishedUnselectedImage:[UIImage imageNamed:@"MyTc.png"]];
[[AppDelegate.Tabctrl.tabBar.items objectAtIndex:2] setFinishedSelectedImage:[UIImage imageNamed:@"Browse-Select.png"] withFinishedUnselectedImage:[UIImage imageNamed:@"Browse.png"]];
[[AppDelegate.Tabctrl.tabBar.items objectAtIndex:3] setFinishedSelectedImage:[UIImage imageNamed:@"Instore-Select.png"] withFinishedUnselectedImage:[UIImage imageNamed:@"Instore.png"]];
[[AppDelegate.Tabctrl.tabBar.items objectAtIndex:4] setFinishedSelectedImage:[UIImage imageNamed:@"More-Select.png"] withFinishedUnselectedImage:[UIImage imageNamed:@"More.png"]];

图片不适合标签栏（我无法发布图片）。有一些设计问题吗？我该如何解决这个问题？

Answer 1

图像的宽度应为（320 /标签栏项目数）。这意味着320/4。

Answer 2

参考这个 Add custom image to UITabBarController

UITabBarItem *tabBarItem1 = [AppDelegate.Tabctrl.tabBar.items objectAtIndex:0];

[tabBarItem1 setFinishedSelectedImage：[UIImage imageNamed：@“Home-Select.png”] withFinishedUnselectedImage：[UIImage imageNamed：@“Home.png”]];

tabBarItem1.imageInsets = UIEdgeInsetsMake（6,0，-6,0）;

Answer 3

 UITabBarItem *tabBarItem1 = [AppDelegate.Tabctrl.tabBar.items objectAtIndex:0];

  [tabBarItem1 setFinishedSelectedImage:[UIImage imageNamed:@"selected.png"] withFinishedUnselectedImage:[UIImage imageNamed:@"unselected.png"]];

此外，您还需要确保图像的大小适合空间。
