Ios progressbar完成后显示alertview

我有用于将图像上载到服务器的应用程序。图像正在成功上载到服务器，progressbar也在工作。但我想在progressbar完成后显示alertview。。。这是我的progressbar代码

- (void)connection:(NSURLConnection *)connection didSendBodyData:(NSInteger)bytesWritten totalBytesWritten:(NSInteger)totalBytesWritten totalBytesExpectedToWrite:(NSInteger)totalBytesExpectedToWrite
{
     float progress = [[NSNumber numberWithInteger:totalBytesWritten] floatValue];
     float total = [[NSNumber numberWithInteger: totalBytesExpectedToWrite] floatValue];
     progress_bar.progress = progress/total;
     NSLog(@"%f",progress/total);
}

因此，我的问题是如何在progressbar为100%后显示alertview。

试试这个

if (progress_bar.progress == 1){
    //Add your alertview here. 
}

- (void)connection:(NSURLConnection *)connection didSendBodyData:(NSInteger)bytesWritten totalBytesWritten:(NSInteger)totalBytesWritten totalBytesExpectedToWrite:(NSInteger)totalBytesExpectedToWrite
{
     float progress = [[NSNumber numberWithInteger:totalBytesWritten] floatValue];
     float total = [[NSNumber numberWithInteger: totalBytesExpectedToWrite] floatValue];

     float actualProgress = progress/total; 

     if (actualProgress == 1.0){
         //showAlert
     }
     progress_bar.progress = actualProgress;
     NSLog(@"%f",progress/total);
}

您不能使用

connectiondFinishLoading

delegate方法吗

- (void)connectionDidFinishLoading:(NSURLConnection *)connection {
    // show alert with UIAlertView or iOS8 UIAlertController
}

if（progress==total）{showart}

？或者它可以是

float actualProgress=progress/total；如果（actualProgress==1.0）{showAlert}

我已经将浮点值取为1.0，让我们来看看。
