在将它与按钮一起使用之前删除 BlurEffect
Remove BlurEffect before to use it with a button
我有一个按钮,当我点击它时,我的 background_image 变成了模糊效果。
@IBAction func button_MainClicked2(_ sender: UIButton) {
if button_MainCenter == button_viajes.center{
UIView.animate(withDuration: 0.6, animations:
{
let blur = UIBlurEffect(style: UIBlurEffectStyle.light)
let blurView = UIVisualEffectView(effect: blur)
blurView.frame = self.image_Background.bounds
self.image_Background.addSubview(blurView)
})
} else {
UIView.animate(withDuration: 0.6, animations: {
// I want to remove blur effect as soon as i press the button again.
})
}
}
如何修复它以在单击返回按钮后立即删除效果?
您可以添加 tag
来模糊视图,例如 blurView.tag = 1000
,然后再将其添加为子视图,然后在动画块中
for view in button_MainCenter.subviews {
if view.tag == 1000 {
view.removeFromSuperview()
}
}
编辑:
不确定它是否会被动画化。如果不是,您可以将此视图的 alpha
从 1 变为 0,然后将其删除。
