属性标题未在xib文件的UIButton中加载自定义字体

Question

我在这个问题上全神贯注，无法找出问题所在。 我的一个界面生成器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。 在界面生成器中，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。 我可以在代码中以及控件的非属性标题中正确使用它，并且效果很好。 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，看起来它应该为单词“ got”加载Montserrat：

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

                                        <font key="NSFont" size="15" name="Montserrat-Bold"/>
                                        <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"/>
                                    </attributes>
                                </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>

但是我可以看到iOS在单词“ got”中用“ HelveticaNeueInterface-Regular”替换了“ Montserrat-Bold”的用法。 这是调试器的另一段摘录：

}

在UILabels，模拟器或设备，iOS 7或8上似乎也发生了同样的问题。但是我可以在没有属性的标题上使用Montserrat。 在这一点上，我真的很沮丧。 有人遇到过这个问题吗？

谢谢Omri
