           //ProgressView
           self.progressView = [[UIProgressView alloc] initWithProgressViewStyle:UIProgressViewStyleBar];

推荐答案

我已经修改了你的代码.现在，进度视图正常工作.所有单元格都显示进度视图.此外，宽度 &单元格的位置可以修改，如果你改变下面代码中self.downloadB的frame

I have modified you code. Now, progress view is working properly. All cells are showing the progress view. Also, width & position of the cell can be modified, if you change the frame of self.downloadBin the below code

- (id)initWithFrame:(CGRect)frame
{
    self = [super initWithFrame:frame];
    if (self) {
        // Initialization code
        [self.contentView setBackgroundColor:[UIColor underPageBackgroundColor]];

        //cellImage
        self.imageView = [[UIImageView alloc] initWithFrame:CGRectMake(100, 0, 57, 57)];
        [self.imageView setBackgroundColor:[UIColor clearColor]];
        [self.contentView addSubview:self.imageView];

        //ProgressView
        self.downloadBar = [[UIProgressView alloc] initWithProgressViewStyle:UIProgressViewStyleBar];
        [self.downloadBar setFrame:CGRectMake(0, 10, 300, 10)];

        [self.contentView addSubview:self.downloadBar];
        [self.downloadBar setHidden:YES];

        self.receivedData = [[NSMutableData alloc] init];


    }
    return self;
}

我已经从你提供的 github url 中修改了 cell.m 的代码.

I have modified the code of cell.m from the github url which you have provided.
