Question

我在iPhone开发中是新来的, 想要在我的应用程序中添加进度视图, 有人能帮助我如何在我的 iPhone 应用程序中添加进度视图,

Answer 1

这是使用 mbprogessshud 的样本代码, 希望 u 也可以用此方法设置您进度视图的进展。请参考 nsurldlegate 方法, 它们是如何根据服务器上的数据来设定进度的。

  - (IBAction)showWIthLabelAnnularDeterminate:(id)sender {
        HUD = [[MBProgressHUD alloc] initWithView:self.navigationController.view];
        [self.navigationController.view addSubview:HUD];

        // Set determinate mode
        HUD.mode = MBProgressHUDModeAnnularDeterminate;

        HUD.delegate = self;
        HUD.labelText = @"Loading";

        // myProgressTask uses the HUD instance to update progress
        [HUD showWhileExecuting:@selector(myProgressTask) onTarget:self withObject:nil animated:YES];
    }



    #pragma mark -
    #pragma mark NSURLConnectionDelegete

    - (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response {
        expectedLength = [response expectedContentLength];
        currentLength = 0;
        HUD.mode = MBProgressHUDModeDeterminate;
    }

    - (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data {
        currentLength += [data length];
        HUD.progress = currentLength / (float)expectedLength;
    }

    - (void)connectionDidFinishLoading:(NSURLConnection *)connection {
        HUD.customView = [[[UIImageView alloc] initWithImage:[UIImage imageNamed:@"37x-Checkmark.png"]] autorelease];
        HUD.mode = MBProgressHUDModeCustomView;
        [HUD hide:YES afterDelay:2];
    }

    - (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error {
        [HUD hide:YES];
    }
