iOS UIButton在分配图像时不加载图像

Question

我正在尝试将"图像"分配给"按钮",但由于原因,"图像"不会加载.

    UIImage *bottonImage = [UIImage imageNamed:@"bocinaMute.png"];

    [self.botton.imageView setImage:[UIImage imageNamed:@"mute.png"]];

当我在控制台中打印时,其值为imageView:

po _botton.imageView
<UIImageView: 0x15f53a390; frame = (0 0; 0 0); clipsToBounds = YES; hidden = YES; opaque = NO; userInteractionEnabled = NO; layer = <CALayer: 0x170235c20>>

我究竟做错了什么？

Answer 1

用这个:

[btnTwo setImage:[UIImage imageNamed:@"mute.png"] forState:UIControlStateNormal];

代替

[self.botton.imageView setImage:[UIImage imageNamed:@"mute.png"]];
