我试图在我的导航栏中有两个 UILabel 而不是只有一个。
我点击此链接以获取有关如何执行此操作的信息: 导航栏中的 iPhone 标题和副标题
它运作良好,但我无法让我的文本正确居中。它在按钮之间居中,但默认的标题行为是在时间下方居中。
我在这里看了看,同样的问题,但没有答案: UINavigationBar TitleView with subtitle
我错过了什么?这是我的代码:
CGRect headerTitleSubtitleFrame = CGRectMake(0, 0, 200, 44);
UIView* _headerTitleSubtitleView = [[UILabel alloc] initWithFrame:headerTitleSubtitleFrame];
_headerTitleSubtitleView.backgroundColor = [UIColor clearColor];
_headerTitleSubtitleView.autoresizesSubviews = NO;
CGRect titleFrame = CGRectMake(0, 2, 200, 24);
UILabel *titleView = [[UILabel alloc] initWithFrame:titleFrame];
titleView.backgroundColor = [UIColor clearColor];
titleView.font = [UIFont boldSystemFontOfSize:20];
titleView.textAlignment = NSTextAlignmentCenter;
titleView.textColor = [UIColor whiteColor];
titleView.shadowColor = [UIColor darkGrayColor];
titleView.shadowOffset = CGSizeMake(0, -1);
titleView.text = @"Title";
titleView.adjustsFontSizeToFitWidth = YES;
[_headerTitleSubtitleView addSubview:titleView];
CGRect subtitleFrame = CGRectMake(0, 24, 200, 44-24);
UILabel *subtitleView = [[UILabel alloc] initWithFrame:subtitleFrame];
subtitleView.backgroundColor = [UIColor clearColor];
subtitleView.font = [UIFont boldSystemFontOfSize:13];
subtitleView.textAlignment = NSTextAlignmentCenter;
subtitleView.textColor = [UIColor whiteColor];
subtitleView.shadowColor = [UIColor darkGrayColor];
subtitleView.shadowOffset = CGSizeMake(0, -1);
subtitleView.text = @"Subtitle";
subtitleView.adjustsFontSizeToFitWidth = YES;
[_headerTitleSubtitleView addSubview:subtitleView];
self.navigationItem.titleView = _headerTitleSubtitleView;
