UIButton image not resizing - Swift

我正在创建一个带有png图像的自定义按钮，因为我之前已经完成了数百次。UIButton image not resizing - Swift

但是由于某种原因，这次图像没有按比例缩放。

func constructInfoViewBtns() { 
    let buttonsView = UIView.init(frame: CGRectMake(0, 90, self.infoView!.frame.width, 90)) 

    let playPauseBtn = UIButton(type: UIButtonType.Custom) as UIButton 
    let playPauseBtnImg : UIImage = UIImage(named: "pauseBtn")! 
    playPauseBtn.setImage(playPauseBtnImg, forState: .Normal) 
    playPauseBtn.imageView?.contentMode = UIViewContentMode.ScaleAspectFill 
    playPauseBtn.frame = CGRectMake(0, 0, 55, 55) 
    playPauseBtn.backgroundColor = UIColor.blueColor() 
    playPauseBtn.center = CGPointMake(buttonsView.frame.width/2, buttonsView.frame.height/2) 
    playPauseBtn.addTarget(self, action: "playPauseTrack:", forControlEvents: .TouchDown) 
    self.playPauseBtn = playPauseBtn 

    buttonsView.addSubview(self.playPauseBtn!) 

    self.infoView!.addSubview(buttonsView) 

}

我得到的是一个蓝色框，其中按钮图像小于按钮的框架。喜欢它的填充或东西...

尝试设置的图像作为按钮的背景图像。 @broderickga –

可能是图片大小比按钮框大 –

添加此，并尝试

playPauseBtn.imageEdgeInsets = UIEdgeInsetsMake(25,25,25,25)
