问题
I have created a mail template on mailchimp. It consists of a twitter link. But an IPad or an IPhone user clicks on the link from his/her mail, the twitter link opens in the browser instead of the twitter app.
This does not happen in Android.
Any workarounds?
回答1:
If you use a custom URL <a href="twitter://" than other Android/Desktop devices won't be able to open it. Twitter doesn't redirect with standard URLs from Safari and they should. But they do offer a "Open in app" button at the top left.
So if you want you could add two buttons in the email. One specifically for iOS: twitter://status?id=373205208664272897 and one for other devices https://twitter.com/support/status/373205208664272897.
Or you could create a site that reads the user agent of the device than determines which URL to redirect to.
The third option is just leaving it alone given that it's not really such a big issue in the grand scheme.
回答2:
NSString *stringURL = @"twitter://";
NSURL *url = [NSURL URLWithString:stringURL];
[[UIApplication sharedApplication] openURL:url];
From iPhone URL Schemes.
