变化较小和检查...

NSString *str = [append stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceCharacterSet]]; 
    NSLog(@"%@",str); 
    NSData* imageData = [NSData dataWithContentsOfURL:[NSURL URLWithString:str]]; 
    UIImage* image1 = [UIImage imageWithData:imageData]; 
    NSLog(@"Loaded Image: %@", image1); 

    if (image1 == nil) 
    { 
     cell.photoView.image = [UIImage imageNamed:@"$.png"]; 
     // cell.titleLabel.text = [[paiddic objectAtIndex:indexPath.row]objectForKey:@"group_name"]; 
    } 
    else 
    { 
    cell.photoView.image = image1; 
    } 
    cell.titleLabel.text = [[paiddic objectAtIndex:indexPath.row]objectForKey:@"group_name"];
