ios - Check if UIWebview is displaying PDF -

to clear, question not asking how display pdf in uiwebview. want check if user has navigated pdf (.pdf) document website or link. way can show more options user, saving pdf or printing it. what's best way check if uiwebview's content pdf?

you can check mime type too, longer journey:

@property (nonatomic, strong) nsstring *mime; - (void)connection:(nsurlconnection *)connection didreceiveresponse:(nsurlresponse *)response { mime = [response mimetype]; } - (bool)isdisplayingpdf { nsstring *extension = [[mime substringfromindex:([mime length] - 3)] lowercasestring]; homecoming ([[[self.webview.request.url pathextension] lowercasestring] isequaltostring:@"pdf"] || [extension isequaltostring:@"pdf"]); }
