Question

我正在使用下面的代码，但它没有显示准确的大小，假设我的文件大小为50Mb，但它显示大约90MB。

NSError *error;
NSURL * mediaURL = [info objectForKey:UIImagePickerControllerMediaURL];
NSDictionary * properties = [[NSFileManager defaultManager] attributesOfItemAtPath:mediaURL.path error:&error];
NSNumber * size = [properties objectForKey: NSFileSize];

我也试过下面的代码

NSDictionary *attribs = [[NSFileManager defaultManager] attributesOfItemAtPath:moviePath error:&error];
if (attribs) {
    NSString *string = [NSByteCountFormatter stringFromByteCount:[attribs fileSize] countStyle:NSByteCountFormatterCountStyleFile];
    NSLog(@"%@", string);
}

它也是一样的结果。我想要精确的文件大小。任何人都可以帮助我。谢谢

NSError *attributesError;
NSURL *videoUrl=[info objectForKey:UIImagePickerControllerMediaURL];

    NSDictionary *fileAttributes = [[NSFileManager defaultManager] attributesOfItemAtPath:[videoUrl path] error:&attributesError];
    NSNumber *fileSizeNumber = [fileAttributes objectForKey:NSFileSize];
    long long fileSize = [fileSizeNumber longLongValue];
    NSLog(@"SIZE OF VIDEO: %0.2f Mb", (float)fileSize/1024/1024);

此代码完全正常工作
