將上傳圖像上傳到我的服務器時顯示進度條

Question

我的應用程序將圖像上傳到我的服務器。 我想通過進度條顯示此事件。

- (void)connection:(NSURLConnection *)connection didSendBodyData:(NSInteger)bytesWritten totalBytesWritten:(NSInteger)totalBytesWritten totalBytesExpectedToWrite:(NSInteger)totalBytesExpectedToWrite 

- (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response 

- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data 

- (void)connectionDidFinishLoading:(NSURLConnection *)connection 

我用這個上面的方法來查看控制檯中的指令。 但我怎麼做在使用'進度欄'的筆尖文件？

如果你使用一個UIProgressView可以設置在連接進度：像這樣的方法：didSendBodyData：totalBytesWritten：totalBytesExpectedToWrite

float progress = [[NSNumber numberWithInteger:totalBytesWritten] floatValue]; 
float total = [[NSNumber numberWithInteger: totalBytesExpectedToWrite] floatValue]; 
progressView.progress = progress/total;
