我正在xCode上为iOS构建Notes应用程序。在情节提要中,我有一个表格视图>表格单元格>内容视图;然后在内容视图中,我有三个标签。我遇到了无法正确约束标签的问题,其他所有东西都显示正常。
我尝试了建议的约束条件,并且尝试了几个小时。在情节提要中看起来不错,并且各个方面都有约束。标签之间应该有间距,但是当我在模拟器中运行它时,就好像它忽略了我的约束并决定自己做一样,即将所有标签堆叠在彼此的左上角。我能做什么。我提供了几个截图以及情节提要的源代码片段。我基本上只希望标题在顶部,在其下方是作者的标签,在文本下方。我不明白发生了什么。
This is what the Storyboard looks like
This is how it looks like on the emulator
