Question

我正在使用进度条显示上传到ftpserver的文件的上传百分比，这是第一次更新，当我取消上传时，再次ID我开始。 50％的上传进度条正在填充，第三次为25％的总进度条正在填充。

这是代码（我使用s7ftp类上传到服务器）

- (void)uploadBytesWritten:(S7FTPRequest *)request {


if (uploadedData < totalFileSize) {
    uploadedData = uploadedData + request.bytesWritten;
}
float total = (float)totalFileSize;
float bytes = (float)request.bytesWritten;
float pt = (bytes/total);
float totalSizeMb = (total/1048576);
//    NSLog(@"File Size in Mb:%f",totalSizeMb);
float uploadDataMb = (uploadedData/1048576);
NSString* totalSize = [NSString stringWithFormat: @"%5.1f", totalSizeMb];
NSString* uploadData = [NSString stringWithFormat: @"%5.1f", uploadDataMb];
//    float str = (uploadDataMb/totalSizeMb);
float str = (uploadedData/total);
float string = str*100;
int PercentageFinal = roundf(string);
 NSString *uploadPercentage = [NSString stringWithFormat:@"%d",PercentageFinal];
uploadpercentage = [NSString stringWithFormat:@"%@Mb/%@Mb", uploadData, totalSize];
NSLog(@"Uploading percentage:%@",uploadpercentage);
NSString *percentage = [NSString stringWithFormat:@"%f",pt];
uploadProgressView.progress += [percentage doubleValue];
[[NSNotificationCenter defaultCenter]   postNotificationName:@"UpdatePercentageNotification" object:nil userInfo:[[NSDictionary alloc] initWithObjectsAndKeys:percentage, @"percentage",uploadpercentage,@"UploadPercentage",uploadPercentage,@"Percent",nil]];

}

在另一个班级

-(void)Viewdidload{
      [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(updatePercentageNotificationOne:) name:@"UpdatePercentageNotification" object:nil];
  }

- (void)updatePercentageNotificationOne:(NSNotification *)notification{
NSLog(@"Updating percentage in upload all view");
 //    NSString *uploadpercentage = [[notification userInfo ]objectForKey:@"UploadPercentage"];
//    NSLog(@"Percentage:%@",uploadpercentage);
NSString *percent= [[notification userInfo]objectForKey:@"Percent"];
NSLog(@"percent:%@",percent);
NSString *percentage = [[notification userInfo] objectForKey:@"percentage"];
//    NSLog(@"Percentage......%@",percentage);
percentageLabel.text = percent;
ProgressBar.progress +=[percentage doubleValue];
[[NSNotificationCenter defaultCenter] removeObserver:@"UpdatePercentageNotification"];

 }

ķ 当您再次开始上传时，需要重置progressBar。你只需在上传用户clcks时分配init。

progressBar不可动摇地移动
