ViewsIs there a way for Gmail to recognize line breaks from text from UIapplication.shared.open url
Gmail client does not recognize line breaks within text from UIApplication.shared.openURL(url)
I have a function that returns a tuple of available email clients (validated by UIApplication.shared.canOpen) and the associated URL. It's for an error reporting feature, so the arguments array contains the text that will autopopulate email fields.
There are no issues with launching any of the three email clients, but gmail is the only one that doesn't process the line breaks. Does gmail use a different method?
enum EmailClient {
case gmail
case outlook
case mail
var title: String {
switch self {
case .gmail: return "Gmail"
case .outlook: return "Outlook"
case .mail: return "Mail"
}
}
//Creates url used by UIapplciation.shared to launch the client and autopopulate the email
func url(error: CustomError?) -> URL? {
guard let username = CredentialManager.username,
let appVersion = Bundle.main.infoDictionary?["CFBundleShortVersionString"] as? String else {
return nil
}
let arguments = [
username,
UIDevice().modelName,
UIDevice.current.systemVersion,
appVersion,
error?.description ?? "N/A" //When called from the settings page, no error is passed in
]
var urlFormat: String
switch self {
case .gmail: urlFormat = "googlegmail:///co?to=%@&subject=%@&body=%@"
case .outlook: urlFormat = "ms-outlook://compose?to=%@&subject=%@&body=%@"
case .mail: urlFormat = "mailto:%@?subject=%@&body=%@"
}
return URL(string: String(format: urlFormat, arguments: [
EMAIL_RECIPIENT,
EMAIL_SUBJECT.replacingOccurrences(of: " ", with: "%20"),
String(format: EMAIL_BODY_FORMAT, arguments: arguments).replacingOccurrences(of: " ", with: "%20").replacingOccurrences(of: "\n", with: "%0A")
]))
}
}

It seems that using "\r\n" instead of "\n" fixes the problem

1) Add the the scheme to your info.plist
We can do this through the beautiful thing that is the Info.plist file. Add a new key called LSApplicationQueriesSchemes as an array. Then you can enter your apps within the array. The Mail app doesn’t need to go in here, presumably because it is an Apple app. Your entry should look like the below
func openGmail(withFrom: String?, withSubject: String?) {
var gmailUrlString = "googlegmail:///"
if let from = withFrom {
gmailUrlString += "co?to=\(from)"
}
if let subject = withSubject {
gmailUrlString += "&subject=\(subject)"
}
}
One last thing we will need to do is URL encode the subject line before we pass it into the URL. We can do this by calling subjectString?.addingPercentEncoding(withAllowedCharacters:NSCharacterSet.urlQueryAllowed) on the string.
