答
试试这个,
[manager setDownloadTaskDidWriteDataBlock:^(NSURLSession *session, NSURLSessionDownloadTask *downloadTask, int64_t bytesWritten, int64_t totalBytesWritten, int64_t totalBytesExpectedToWrite) {
float percentageDone = ((float)totalBytesWritten/(float)totalBytesExpectedToWrite)*100;
NSLog(@"Downloading..%.f",percentageDone);
}];
