Answer 1

新しいビューを追加する前にこれを使用してください:

for (UIView *subview in [self.view subviews]) {
    [subview removeFromSuperview];
}

Answer 2

アクションが実行されるUIViewたびに作成されている場合。UITabBar

[view removeFromSuperview];

self.view に追加されたすべてのアイテムを削除する場合

for (id view in self.view) {
    [view removeFromSuperview];
}

それ以外の場合は使用

view.hidden=TRUE;
