【问题描述】:
我的问题
我正在尝试在 touchInside button 时使用 UIView.animate(..) 做一些带有标签的动画。在我添加一行之前,一切都还可以:“self?.confirm.setTitle("Đăng nhập", for: .normal)。动画不起作用。
我的意愿
我希望 Đăng Ký 下方的黄色下划线切换到 Đăng nhập 下方。
有代码就好了
@IBAction func signUpAction(_ sender:Any?){
if (signup == false){
signup = true
UIView.animate(withDuration: 0.4, delay: 0, options: [.curveEaseIn], animations: {[weak self] in
self?.underlineSignup.center.x -= (self?.underlineSignup.bounds.width)!
self?.view.layoutIfNeeded()
}, completion: nil)
}
}
@IBAction func signInAction(_ sender:Any?){
if (signup == true){
signup = false
UIView.animate(withDuration: 0.4, delay: 0, options: [.curveEaseIn], animations: {[weak self] in
self?.underlineSignup.center.x += (self?.underlineSignup.bounds.width)!
self?.view.layoutIfNeeded()
}, completion: nil)
}
}
但是当我添加 .setTitle
@IBAction func signUpAction(_ sender:Any?){
if (signup == false){
signup = true
UIView.animate(withDuration: 0.4, delay: 0, options: [.curveEaseIn], animations: {[weak self] in
self?.underlineSignup.center.x -= (self?.underlineSignup.bounds.width)!
self?.confirm.setTitle("Đăng ký", for: .normal)
self?.view.layoutIfNeeded()
}, completion: nil)
}
}
@IBAction func signInAction(_ sender:Any?){
if (signup == true){
signup = false
UIView.animate(withDuration: 0.4, delay: 0, options: [.curveEaseIn], animations: {[weak self] in
self?.underlineSignup.center.x += (self?.underlineSignup.bounds.width)!
self?.confirm.setTitle("Đăng nhập", for: .normal)
self?.view.layoutIfNeeded()
}, completion: nil)
}
}
It stuck, only the title of button confirm change, the underline doesn't move
请任何人解释一下这种情况。
编辑:
动画工作,但它的目的地总是在Đăng ký下的第一位(动画来自它的左侧或右侧,结果总是第一位)
【问题讨论】:
-
你能把标题设置成另一个字符串,比如“hello”吗?
-
是的,我可以,意思是用越南语登录和注册
-
我要问的是:当您使用仅具有拉丁字形的字符串时,应用程序是否可以正常工作?
-
我全部改成了拉丁字形(例如:setTitle("ok") all of above and mainboard)但它仍然是
