iphone - 使用 asihttp 请求在表中发出带有进度条的多个请求

Question

我正在使用asihhtp请求在ios中发出多个图像上传请求以将图像提交到服务器。但是我的应用程序总是由于进度条而崩溃。这是我的代码

                ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:[NSURL URLWithString:urlStr]];
                [request appendPostData:postData];
                [request setTag:[[dic objectForKey:@"unique"] integerValue]];
                [request setDelegate:self];
                [request setUploadProgressDelegate:cell.mProgressBar];
                [request setDidFailSelector:@selector(requestFail:)];
                [request setDidFinishSelector:@selector(requestDone:)];
                [request setRequestMethod:@"POST"];
                [request addRequestHeader:@"Content-Type" value:@"text/plain"];
                [request setShouldContinueWhenAppEntersBackground:YES];
                //[myQueue addOperation:request];
                [appDelegate window].userInteractionEnabled = NO;
                [request startAsynchronous];

我有自定义单元格，其中有进度条和标签，因此一旦流程完成，我就会隐藏进度条并显示已完成的标签。

用户滚动表格应用崩溃使用进度条时出现问题

崩溃输出

> -[UIProgressView respondsToSelector:]: message sent to deallocated instance 0x10d210c0

自定义单元格代码

    #import <UIKit/UIKit.h>

    @interface CustomProgressBar : UITableViewCell
    {

    }

    @property (retain, nonatomic) IBOutlet UILabel         *mlblCompllrtrlbl;
    @property (retain, nonatomic) IBOutlet UIProgressView  *mProgressBar;
    @property (retain, nonatomic) IBOutlet UIImageView     *mCellImafge;

    @end

自定义单元格代码

    #import "CustomProgressBar.h"

    @implementation CustomProgressBar
    @synthesize mlblCompllrtrlbl;
    @synthesize mProgressBar;
    @synthesize mCellImafge;

    - (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString*)reuseIdentifier
    {
    self = [super initWithStyle:style reuseIdentifier:reuseIdentifier];
    if (self) {
        // Initialization code
    }
    return self;
    }

    - (void)setSelected:(BOOL)selected animated:(BOOL)animated
   {
    [super setSelected:selected animated:animated];

    // Configure the view for the selected state
   }

   - (void)dealloc 
   {
    [mCellImafge release];
    [mlblCompllrtrlbl release];
    [mProgressBar release];
    [super dealloc];
   }

   @end

您可能在某处发布了progressview，所以首先删除该语句

[UIProgressView发布];
