How can I declare string as with a paragraph with swift?
Question
I want to declare string with p paragraph by swift , like following, but not right, can anyone give me a favor?
I don't want to declare string with one line , which is not easy to read
let format = "<p><strong>%@ paddock selected</strong></p>
<p>Total Area %.1f ha</p>
<p>Effective Area %.1f ha</p>
<p></p>
<p><strong>%@</strong></p>
<p>Total Area %.1f ha</p>
<p>Effective Area %.1f ha</p>"
And I don't want somethings like following, I have to add " at leading and " + and trailing :(
let format = "<style>" +
"p {" +
" margin: 1 1 1 1;" +
"}" +
"</style>" +
"<body>" +
"<p><strong>%@ paddock selected</strong></p>" +
"<p>Total Area %.1f ha</p>" +
"<p>Effective Area %.1f ha</p>" +
"<p></p>" +
"<p><strong>%@</strong></p>" +
"<p>Total Area %.1f ha</p>" +
"<p>Effective Area %.1f ha</p>" +
"</body>"
With objective-c , I just need to add \\ each line will be ok, but not well in swift
NSString* format = @"<p><strong>%@ paddock selected</strong></p>\
<p>Total Area %.1f ha</p>\
<p>Effective Area %.1f ha</p>\
<p></p>\
<p><strong>%@</strong></p>\
<p>Total Area %.1f ha</p>\
<p>Effective Area %.1f ha</p>";

Swift lacks this feature. It has neither autoconcatenation of string literals nor here documents. File a bug report if it's important to you.
What I do is load big strings, including format strings, as a text file from the app bundle.

You can use the multiline format into Localizable.strings (which also is the right place where to write strings).
Please note that this method will actually add newline instructions at the end of each line! However this should not be a problem in your case since you are writing HTML.

This is not directly related to your question, however you could also find useful this String extension
extension String {
var localized: String {
return NSLocalizedString(self, comment: "")
}
}
since it does allow you to retrieve the localized version of your string simply writing
"Test".localized
