    UIImage *buttonImage = [UIImage imageNamed:@"image.png"];
    [sender setImage:buttonImage forState:UIControlStateHighlighted];
    UIImage *buttonImage1 = [UIImage imageNamed:@"image.png"];
    [sender setImage:buttonImage1 forState:UIControlStateNormal];

Answer 2

您可以自定义＆＃34;突出显示的＆＃34;您在Interface Builder中的状态，或使用此代码：

[self.button setImage:[UIImage imageNamed:@"normal"] forState:UIControlStateNormal];
[self.button setImage:[UIImage imageNamed:@"pressed"] forState:UIControlStateHighlighted];

首先修复Backgroudimage is @"image1.jpeg"中的xib，然后

- (IBAction)mybutton:(id)sender
{
 [_buttonrefrence setBackgroundImage:[UIImage imageNamed:@"download.jpeg"] forState:UIControlStateHighlighted];
}
