为什么我的UIButton在分配图像后会改变大小和位置？我怎么能保持一样？

Question

我为其分配图像后，我的UIButton尺寸和位置发生了变化。我不知道为什么。有人知道吗？

我尝试将按钮重新定位到原来的位置，但它不起作用。

CGRect buttonFrame = _subscribeButton.frame;
CGAffineTransform transform = _subscribeButton.transform;

[_subscribeButton setTitle:@"Subscribe" forState:UIControlStateNormal];

[_subscribeButton setImage:[UIImage imageNamed:@"bigButton.png"] forState:UIControlStateNormal];

[_subscribeButton setFrame:buttonFrame];
[_subscribeButton setTransform:transform];

Answer 1

我应该设置backgroundImage而不是图像。这是整个问题。纵横填充仅影响背景图像，因为这是由框架缩放的。

回答：[button setBackgroundImage：[UIImage imageNamed：@“blah.png”]];

Answer 2

change this

CGAffineTransform transform = _subscribeButton.transform;

to

CGAffineTransform transform = CGAffineTransformIdentity;

<强>更新

CGRect buttonFrame = _subscribeButton.frame;

CGAffineTransform transform = CGAffineTransformIdentity;

[_subscribeButton setTitle:@"Subscribe" forState:UIControlStateNormal];

[_subscribeButton setImage:[UIImage imageNamed:@"bigButton.png"] forState:UIControlStateNormal];

[_subscribeButton setContentMode:UIViewContentModeScaleToFill];

_subscribeButton.autoresizingMask = UIViewAutoresizingNone;

_subscribeButton.autoresizesSubviews = NO;



[_subscribeButton setFrame:buttonFrame];

[_subscribeButton setTransform:transform];

Answer 3

试试这个

 CGRect buttonFrame = _subscribeButton.frame;
    CGAffineTransform transform = CGAffineTransformIdentity;

    [_subscribeButton setTitle:@"Subscribe" forState:UIControlStateNormal];

    [_subscribeButton setImage:[UIImage imageNamed:@"bigButton.png"] forState:UIControlStateNormal];

    [_subscribeButton setFrame:buttonFrame];
    [_subscribeButton setTransform:transform];
