ios - 如何让Uibutton被选中

Question

我有一个 UIButton，当我选择该按钮时它仍然处于选中状态。这是我的代码:

- (IBAction)cloudclick:(UIButton *)sender {
    UIImage *bgImage = [UIImage imageNamed:@"black_cloud.png"];
    UIButton *tmpButton = (UIButton *)[self.view viewWithTag:sender.tag];
    [tmpButton setBackgroundImage:bgImage forState:UIControlStateSelected];

} 

但是当我点击按钮时它并没有保持选中状态。它会更改背景，但不会保留为选定按钮。

Answer 1

你必须在你的代码后写一行

- (IBAction)cloudclick:(UIButton *)sender {
    ...
    [tmpButton setSelected:YES];
}
