最初の「redefineLayout」は要素の新しい位置を計算し、2 つ目は回転後のフック「didRotateFromInterfaceOrientation」です。

- (void)redefineLayout
{
    int margin = 20;
    int buttonWidth = ((int)self.view.frame.size.width - margin * 4)/3;

    [self.buttonNewOrder setFrame:CGRectMake(margin, 20, buttonWidth, 200)];
    [self.buttonStatistics setFrame:CGRectMake(margin * 2 + buttonWidth, 20, buttonWidth, 200)];
    [self.buttonSincronize setFrame:CGRectMake(margin * 3 + buttonWidth * 2, 20, buttonWidth, 200)];
}

- (void)didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation
{
    [self redefineLayout];
}

私のインターフェイスは機能しますが、回転後、要素が素早く見苦しい動きをすることがわかります。この動きをより滑らかにしたいと思います。なにか提案を？

私の解決策：

- (void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration
{
    [self redesignLayout:duration];
}

- (void)redesignLayout:(NSTimeInterval)duration {
    [UIView animateWithDuration:duration animations:^{
        int margin = 20;
        int buttonWidth = (((int)self.view.frame.size.width) - margin * 4)/3;
        [self.buttonNewOrder setFrame:CGRectMake(margin, 20, buttonWidth, 200)];
        [self.buttonStatistics setFrame:CGRectMake(margin * 2 + buttonWidth, 20, buttonWidth, 200)];
        [self.buttonSincronize setFrame:CGRectMake(margin * 3 + buttonWidth * 2, 20, buttonWidth, 200)];
    }];
}

- (void)viewDidLoad
{
    [super viewDidLoad];
    [self initLayout];
    [self redesignLayout:0];
}

didRotateFromInterfaceOrientation呼び出しを次のように置き換えてみてください。

- (void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation duration:(NSTimeInterval)duration
{
    [UIView animateWithDuration:duration animations:^{
        [self redefineLayout];
    }];
}
