ios - 标签栏图标全部加载，除了第一个。在模拟器中工作。目标-c

Question

我正在加载所有标签栏图像，并且图像在模拟器上加载，但第一个标签栏项目图像未在设备上加载。

UITabBar *tabBar = self.tabBarController.tabBar;

UITabBarItem *item0 = [tabBar.items objectAtIndex:0];
UITabBarItem *item1 = [tabBar.items objectAtIndex:1];
UITabBarItem *item2 = [tabBar.items objectAtIndex:2];
UITabBarItem *item3 = [tabBar.items objectAtIndex:3];
[item0 setTitle:@"icon1"];
[item1 setTitle:@"icon2"];
[item2 setTitle:@"icon3"];
[item3 setTitle:@"icon4"];


[item0 setFinishedSelectedImage:[UIImage imageNamed:@"icon1.png"] withFinishedUnselectedImage:[UIImage imageNamed:@"icon1"]];
[item1 setFinishedSelectedImage:[UIImage imageNamed:@"CalendarIconSelected"] withFinishedUnselectedImage:[UIImage imageNamed:@"CalendarIconSelected"]];
[item2 setFinishedSelectedImage:[UIImage imageNamed:@"News"] withFinishedUnselectedImage:[UIImage imageNamed:@"News"]];
[item3 setFinishedSelectedImage:[UIImage imageNamed:@"Events"] withFinishedUnselectedImage:[UIImage imageNamed:@"Events"]];



[item1 imageInsets];
[item2 imageInsets];
[item3 imageInsets];

Answer 1

很常见的情况是文件名输入错误。由于某种原因，模拟器对图像文件不区分大小写。另一方面是设备。

所以检查并仔细检查文件名中的每个字符。是 Icon1.png 还是 icon1.PNG。
