Swift shardApplication().openURL() with data URI

Question

So I have a String with the template of

let dataURI = 'data:MIMEType;base64,DATA'

where the data is filled with a bunch of base64 representing the file I want to open. This url will load in a WKWebView or UIWebView; however, when I try to take the same URL and open it via

let uri = NSURL(string: dataURI)
UIApplication.sharedApplication().openURL(uri)

I get the error

LaunchServices: ERROR: There is no registered handler for URL scheme data

I also attempted a string with the format of

let uristring = 'data://' + dataURI 

which gets the same error.

Any ideas whats going on here?

Thanks!

iOS仅包含一些网址计划的处理程序（特别是http，mailto，tel和sms）。不幸的是，它没有对data方案的内置支持。因此，操作系统不知道它可以将您的数据传递给Safari进行显示。
