iphone - Load UIImage form NSData in UIWebView and center it -

-

So I basically get NSData of UIImage and I UIWebView I do this to display: 

  [self.view addSubview: webView]; WebView.delegate = self; WebView.scalesPageToFit = Yes; WebView.backgroundColor = [UIColor darkGrayColor];   
 Then I load it in the image like this:  
  NSData * image02Data = attachmentToLoad.attachment_data; [WebView load data: image02 Data MIMEType: @ "image / jpg" text encoding name: zero baseURL: zero];   
 And I'm getting results that I really do not want:  
  Enter image details here   
 As you can see, the image below leaves a white bottom line beneath the  UIWebView . How do I make the size of  UIWebView  equal to that image?   
 
 
 Did you see this post?  
 I think you really want

Trying to open Solver's VBA code is not good because it There is allegedly copyright. Besides, I do not think Solver creates any disadvantages while working with Excel or VBA.

github - Teamcity & Git - PR merge builds - anyway to get HEAD commit hash? -

-
I have a team city build project with Gitbab VCS route, I have been triggered for both / head on PR and / Merge the referee. The annoying thing is that you can not do anything useful with the merged hash - it is not present in Gitobb. I want to exclude newsgate packages with head in gutub comet situations in the version number along with Hewash (Newsaging 7) for the music build, but against head hash. However, I can not see a way to get the head hashes while constructing that merge. I just want to head because it's useless - we only care about merge. (PR - Pull Request) This command works reliably while running One on / merge is git log --no-merge -1 ---- = '% h'
