【问题描述】：

我正在努力解决这个问题，但不知道出了什么问题。我的一个界面构建器 xib 中有一个按钮，该按钮具有标题的属性字符串，该标题使用添加到我的应用程序中的自定义字体。界面生成器中的一切看起来都很好。

我 100% 确信我已将字体 (Montserrat) 正确加载到我的应用程序中。我可以在整个代码和控件的非属性标题中正确使用它，它工作正常。我还检查了调试器并正确列出了字体：

(lldb) po [UIFont familyNames]

<__NSCFArray 0x7bb34e20>(
Thonburi,
...
Montserrat,
...
Bodoni 72 Smallcaps
)

(lldb) po [UIFont fontNamesForFamilyName:@"Montserrat"]

<__NSCFArray 0x7be75400>(
Montserrat-Regular,
Montserrat-Bold
)

我还可以在文本编辑器的 xib 文件中看到，它看起来应该加载 Montserrat 的单词“got”：

                        <state key="normal">
                            <attributedString key="attributedTitle">

                                        <paragraphStyle key="NSParagraphStyle" alignment="center" lineBreakMode="wordWrapping" baseWritingDirection="natural"/>

                                <fragment content=" an account? ">

                                        <font key="NSFont" size="15" name="Helvetica"/>
                                        <paragraphStyle key="NSParagraphStyle" alignment="center" lineBreakMode="wordWrapping" baseWritingDirection="natural"/>

                                </fragment>
                                <fragment content="SIGN IN!">
                                    <attributes>
                                        <color key="NSColor" red="0.0" green="0.0" blue="0.0" alpha="1" colorSpace="calibratedRGB"/>
                                        <font key="NSFont" size="15" name="Helvetica-Bold"/>
                                        <font key="NSOriginalFont" size="15" name="Helvetica-Bold"/>
                                        <paragraphStyle key="NSParagraphStyle" alignment="center" lineBreakMode="wordWrapping" baseWritingDirection="natural"/>
                                    </attributes>
                                </fragment>
                            </attributedString>
                        </state>

但我可以看到 ios 在“got”一词中用“HelveticaNeueInterface-Regular”取代了我对“Montserrat-Bold”的使用。这是调试器的另一个摘录：

UILabels、模拟器或设备、iOS 7 或 8 上似乎也发生了同样的问题。但我可以在非属性标题上使用 Montserrat。在这一点上我真的很难过。有人遇到过这个问题吗？

谢谢， 暗里
