Question

我已经以编程方式定义了UITabBar但如何在项目处于活动状态时设置自定义UITabBar图标？

以下是我用于声明UITabBar按钮的代码，但如何在自定义图片处于活动状态时设置它？

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];

    if (self) {
        self.title = NSLocalizedString(@"Free", @"Free");
        self.tabBarItem.image = [UIImage imageNamed:@"Free.png"];
    }

    return self;
}

Answer 1

iOS7中的新功能，现在的方法是使用selectedImage上的tabBarItem属性：

self.tabBarItem.selectedImage = [UIImage imageNamed:@"Free_Selected.png"];

Answer 2

您需要为每个标签栏项目设置正常和选定状态：

UIImage *normalImg = [UIImage imageNamed:@"Free.png"];
UIImage *selectedImg = [UIImage imageNamed:@"Free_Selected.png"];

[self.tabBarItem setBackgroundImage:normalImg forState:UIControlStateNormal]; //Normal
[self.tabBarItem setBackgroundImage:selectedImg forState:UIControlStateSelected]; //Selected

为UITabBar设置活动图像
