UITextView私は一週間ずっとサイズを変更しようとしていました。これをどのように行うべきかわからないので、実質的にすべての関連コードを含めることにしました。
私はこの会話ビューを持っています:
この会話ビューは、(制約を使用して) 内部UIViewControllerにあるものです。UITableView2 つのサブビューを含むカスタムUIViewサブクラスConversationToolbarをinputAccessoryView(それUIViewControllerを含むものはファーストレスポンダになる可能性があるため、ビューは常に表示されます) に設定しています。1 つはUITextView左右のボタン用、もう 1 つは顔文字用です。絵文字は、左ボタンをタップしたときにのみ表示されます。
いずれかを選択すると、フローティング ラベルに表示されます。
UITextView複数の行が使用されている場合、これのサイズを変更するのに問題があります。すべてのフレームを自分で計算しようとしましたが、それは私の制約と奇妙な方法で競合しているようです。ほとんどの場合UITextView、小さすぎるか、別のキーを押してビューを更新した後にのみサイズが変更されます。または、UITextViewキーボード上で が大きくなったり、キーボードを閉じるとスライドして見えなくなったりします。
コードからすべてのサイズ変更機能を削除しました。このサイズ変更を行うために必要なことを知りたいです。
私の中でConversationViewController：
var toolbar: ConversationToolbar!
override var inputAccessoryView: UIView! {
get {
if toolbar == nil {
toolbar = NSBundle.mainBundle().loadNibNamed("ConversationToolbar", owner: nil, options: nil).last! as ConversationToolbar
toolbar.frame.size = CGSize(width: UIScreen.mainScreen().bounds.size.width, height: 80)
toolbar.delegate = self
toolbar.setDraft(conversation.draft)
}
return toolbar
}
}
であることConversationToolbar.xibで：
