webview - iOS UIWebView leaked -

class myviewcontroller: uiviewcontroller {      @iboutlet weak var webview: uiwebview?      override func viewdidload() {     super.viewdidload()      let url = nsurl(string: urlstring)     let request = nsurlrequest(url: url!)     svprogresshud.show()      webview?.loadrequest(request)     webview?.scrollview.header = mjrefreshnormalheader(refreshingblock: {        [weak self] in       if let strongself = self {         strongself.webview?.reload()       }})   }      override func viewdiddisappear(animated: bool) {     super.viewdiddisappear(animated)       svprogresshud.dismiss()   }    }  extension myviewcontroller: uiwebviewdelegate {      func webviewdidfinishload(webview: uiwebview) {     webview.scrollview.header.endrefreshing()     svprogresshud.dismiss()   }       func webview(webview: uiwebview, didfailloadwitherror error: nserror?) {     webview.scrollview.header.endrefreshing()     svprogresshud.dismiss()   }    }

according an answer posted here, there workaround if set configuration.selectiongranularity wkselectiongranularitycharacter, leaks stop:

let config = wkwebviewconfiguration() config.selectiongranularity = .character //wkselectiongranularitycharacter let mywebview = wkwebview(frame: frame, configuration: config) 

this worked me, then, when selecting text, there no selection rectangle in webview. may or may not viable workaround in case.

edit noticed question uiwebview, not wkwebview. doesn't can set on uiwebview. i'll leave answer since wkwebview folks googling memory leak find thread...
