将图像上传到我的服务器时显示进度条

我的应用程序将图像上传到我的服务器。我想通过进度条显示此事件。

- (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

我使用上述方法来查看控制台中的进度。但我如何使用“进度条”在 nib 文件中做到这一点？

如果您使用 UIProgressView，您可以在 connection:didSendBodyData:totalBytesWritten:totalBytesExpectedToWrite: 方法中设置进度，如下所示：

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

If you use a UIProgressView you can set the progress in the connection:didSendBodyData:totalBytesWritten:totalBytesExpectedToWrite: method like this:

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