Uibuttong在64位ipad视网膜中选择后没有改变图像？

Question

UIButton在32位iPad中更改其图像但在64位iPad视网膜中选择后不更改图像（仅使用高分辨率图像）。您能否提供一些相关信息？

[btn setBackgroundImage:[UIImage imageNamed:@"inactive.png"] forState:UIControlStateNormal];
[btn setBackgroundImage:[UIImage imageNamed:@"active.png"] forState:UIControlStateSelected];

Answer 1

你能试试吗？在按钮操作方法里面放

- (IBAction)buttonSelected:(UIButton*)sender
{
    [sender setSelected:!sender.selected];
}
