iphone - UISegmentedControl选中状态图标图片

Question

如何为 UISegmentedControl 的 selected 状态设置图标图像？ UISegmentedControl 真的缺少此功能还是只是我缺少技能？

Answer 1

   [segmentedControl addTarget:self action:@selector(segmentAction:) forControlEvents:UIControlEventValueChanged];

-(void)segmentAction:(UISegmentedControl*)sender {

    [sender setImage:[UIImage imageNamed:@"image.png"] forSegmentAtIndex:sender.selectedSegmentIndex];

}
