[UIColor colorWithRed：0.000绿色：0.333蓝色：0.557 alpha：1.000]
应该给海洋颜色。
我看到直接选择对象的海洋颜色（在我的情况下是按钮）属性时颜色不完全相同：你知道是否有工具可以准确检测特定颜色的值吗？

颜色选择器会帮助你吗？在Mac上，我使用http://colorsnapper.com/，如果是网页，我会使用https://chrome.google.com/webstore/detail/pendule。
您可以将鼠标悬停在所需的颜色上，然后获取十六进制代码。有关从十六进制转换为UIColor的详细信息，请参阅How can I create a UIColor from a hex string?，或使用此handy web app。
（注意：ColorSnapper不是免费的，但它有一个iOS UIColor选项，无需你自己转换为十六进制）
答案 2 :(得分：1)
以下是上面Timm Kent's答案的略微修改版本。此版本使用类常量来避免在引用颜色时输入括号。
使用常量，而不是键入以下内容：
let myColor = UIColor.cantaloupe()
您可以输入以下内容：
let myColor = UIColor.cantaloupe
