我正在使用进度条来显示上传到 ftpserver 的文件的上传百分比，这是它第一次很好地更新，当我取消上传并再次启动时。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（我正在使用 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"];
}
