如何在 Objective-C 中从右上角淡入和展开模态框

Question

我正在尝试让我的 CalendarFlyoutView 在 Xcode 和 Objective-C 中淡入并从右上角展开。这是实现文件中存在的方法：

- (void)presentInView:(UIView *)holderView completion:(void (^) (void))completion
{
    // make this view stretch
    CGRect upperRightR = CGRectMake (CGRectRight (holderView.bounds), 0, 1, 1);
    [self setFrame:upperRightR];
    self.clipsToBounds = YES;
    self.alpha = 0.0;

    [holderView addSubview:self];

    [UIView animateWithDuration:kAnimation_ExpandCalendarDuration
        animations:^{
          [self setFrame:holderView.bounds];
          self.alpha = 1.0;
        }
        completion:^(BOOL finished){
        }];
}

如何使它从右上角淡入和展开？任何帮助将不胜感激。

这似乎是正确的，也许检查一下右上角的自动布局？这可能会导致问题...
