Add UIProgressView to a NSURLConnection?

由 巧了我就是萌 提交于 2019-12-08 06:49:46
问题 Is it possible to add a UIProgressView to a NSURLConnection? Is it as simple as getting the length of the data and then setting it to an int then sending that int to my other class to my UIProgressView? Can someone show me how to do this? Are there any examples or links that will point me in the right direction? Thanks!!! 回答1: In your didReceiveResponse function you could get the total filesize like so - _totalFileSize = response.expectedContentLength; . In your didReceiveData function you

问题 I'm using a POST request to upload some data to a server, and I'm trying to update the UIProgressView's progress based on the totalBytesWritten property of the didSendBodyData method of NSURLConnection . Using the below code, I don't get a proper updating of the progress view, it's always 0.000 until it finishes. I'm not sure what to multiply or divide by to get a better progress of the upload. I'd appreciate any help offered! Code: - (void)connection:(NSURLConnection *)connection

问题 I'm trying to develop a progress view inside UITableViewCell . In my first realization I used AFHTTPRequestOperation and its setDownloadProgressBlock:^ inside my cell. Later my goal became more complicated. I have one UITableView that displays different content (song playlists). The same song might exits in several playlists. When I start to download the song in one playlist and switch to another (which also contains this song) I want to see the download progress like in the first playlist. I

iOS - UIProgressView only updating once

由 本小妞迷上赌 提交于 2019-12-06 01:44:54
I am loading data from an API and am using a UIProgressView to display how much has loaded. In my viewWillAppear I use Reachability to check that there is an internet connection. Then, if there is, the following line is called 10 times in a function. [self performSelectorInBackground:@selector(updateProgress) withObject:nil]; This then runs this method -(void)updateProgress { float currentProgress = myProgressBar.progress; NSLog(@"%0.2f", currentProgress); [loadingProg setProgress:currentProgress+0.1 animated:YES]; } The float increments by 0.1 and the loading view displays this. When the view

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 6 years ago . UIProgressView doesn't allow any customization. I know it's not exactly something complicated, but still I'd prefer to use an open sourced solution rather than re-inventing my own wheel. Are there any? 回答1: There are many at Cocoa Controls, some are more customizable than others. I like ATMHud. ... 回答2: Github

Why isn't UIProgressview progress bar resizable?

问题 From Bavarious' question about UIProgressViews here: I tried implementing what Dave DeLong said and I did everything the exact way he showed in his example, but when I run the program, my progress bar becomes a stretched image if I try changing the value of the progress. The track image however resizes perfectly and repeats along the track. For some reason, the progress isn't doing this along the progress bar. UIImage * load = [[UIImage imagedNamed:@"load.png"] resizableImageWithCapInsets
