  iphone nsurlconnection nsurlrequest
  I am using Storyboard with a Navigation Controller and prepareforsegue. I have two UITableViews. If you click on a row in the first table you get to the second table. The second table picks its data from a plist depending which row you clicked in the first table. This works fine as long there is an internet connection. If there is no internet connection it crashes.Now I want to check if there is an internet connection before the second table loads. And if there is no internet connection I want t

  iphone ios nsurlrequest
  I am experiencing an issue that has been reported in the following link: NSOperation, Synchronous NSURLConnection, & UIWebView on iPhonedescribing an issue when using NSOperationQueue and UIWebView in the same iOS App.The error I receive is slightly different – it returns ‘frame should already be nil’ but the described behaviour is roughly the same (app crashes). Seems UIWebView doesn’t like URLRequests being made by someone else first! :)The suggested workaround seems to fix the problem, bu

  ios monotouch nsurlrequest nsmutableurlrequest
  I have some code in objective-C which uses the ‘mutableCopy’ method to make a mutable copy of an NSURLRequest object called ‘request’:NSMutableURLRequest mutableRequest = [request mutableCopy];How do I go about doing this in Monotouch?I tried putting this code into an Objective-C monotouch binding dll but when I call the function which has this code in it, I get a hard crash in the simulator and the monodevelop ide unloads itself from memory spontaneously. The crash presumably has to do with t

  iphone nsurlconnection nsurlrequest sendasynchronousrequest
  So till some point of time I used this:[NSURLConnection sendAsynchronousRequest:request queue:[NSOperationQueue mainQueue]completionHandler:^(NSURLResponse *response, NSData *data, NSError *error) { …Some code here }];But then I realized that there is always one case when such approach crashes the app.For example, try use code on slow internet connection and till the block is done try to enter background and then return to the app again. You’ll see that it crashes with EXC_BAD_ACCESSSo is send

  My app is crashing when I try to post images in an HTTP request. I am trying to upload images to a server. The crash appears related to my autorelease pool because the crash is trapped at the [pool release] message.

  I’m using the latest stable releases of Mono/Monotouch/MonoDevelop on a iOS 5.0 iPhone and iPad. I have a UIWebView that in the emulator never crashes however randomly on the actual devices it crashes on EXC_BAD_ACCESS. Based on everything I’ve read with UIWebViews that most likely occurs when the UIWebView gets disposed before it finishes loading.Here is the code I am using in my ViewDidLoad():var urlAddress = BASE_URL + _page; var nsURL = new NSUrl(urlAddress); var nsURLRequest = new NSUrlRe

  objective-c ios nsurlrequest
  I’m using the OAuthConsumer library by Jon Crosby (google code link)I have successfully set up my project with a access & request token/secret to make basic authorized http requests with the server (GET). However now I need to create a call that uploads an image to the server…(POST)As far as i’ve found out, i need to define the entire httpBody myself (correct me if i’m wrong). I found some sample code somewhere that appends data to the httpBody but I have absolutely no idea what i’m doing.
