Python .read（）不会读取整个二进制文件

Question

我正在尝试构建一个程序来从class BookTableViewCell: UITableViewCell { let nameLabel = UILabel(frame: .zero) let detailLabel = UILabel(frame: .zero) let dateLabel = UILabel(frame: .zero) let authorProfileImg = UIImageView(frame: .zero) // MARK: Initalizers override init(style: UITableViewCell.CellStyle, reuseIdentifier: String?) { super.init(style: style, reuseIdentifier: reuseIdentifier) let marginGuide = contentView.layoutMarginsGuide // add the subviews contentView.addSubview(nameLabel) contentView.addSubview(detailLabel) contentView.addSubview(dateLabel) contentView.addSubview(authorProfileImg) // we will use auto-layout constraints nameLabel.translatesAutoresizingMaskIntoConstraints = false detailLabel.translatesAutoresizingMaskIntoConstraints = false dateLabel.translatesAutoresizingMaskIntoConstraints = false authorProfileImg.translatesAutoresizingMaskIntoConstraints = false // configure labels and image view properties nameLabel.numberOfLines = 0 nameLabel.font = UIFont(name: "Arial", size: 16) detailLabel.numberOfLines = 0 detailLabel.font = UIFont(name: "Arial", size: 13) detailLabel.textColor = UIColor.lightGray dateLabel.numberOfLines = 0 dateLabel.font = UIFont(name: "Arial", size: 12) dateLabel.textColor = UIColor.red dateLabel.text = "Jun 5" authorProfileImg.layer.cornerRadius = 25 authorProfileImg.backgroundColor = .blue // set the constraints NSLayoutConstraint.activate([ // image view leading is marginGuide leading authorProfileImg.leadingAnchor.constraint(equalTo: marginGuide.leadingAnchor, constant: 0.0), // image view centered vertically in cell authorProfileImg.centerYAnchor.constraint(equalTo: marginGuide.centerYAnchor, constant: 0.0), // if we want image view constrained to top of marginGuide (aligned to top of cell), // comment the above line (the centerYAnchor line) and un-comment this next line //authorProfileImg.topAnchor.constraint(equalTo: marginGuide.topAnchor, constant: 0.0), // image view is 50x50 authorProfileImg.widthAnchor.constraint(equalToConstant: 50.0), authorProfileImg.heightAnchor.constraint(equalTo: authorProfileImg.widthAnchor), // name label constrained to top // leading is 10-pts from image view trailing // trailing is marginGuide trailing nameLabel.topAnchor.constraint(equalTo: marginGuide.topAnchor, constant: 0.0), nameLabel.leadingAnchor.constraint(equalTo: authorProfileImg.trailingAnchor, constant: 10.0), nameLabel.trailingAnchor.constraint(equalTo: marginGuide.trailingAnchor, constant: 0.0), // detail label top constrained 5-pts from bottom of name label // leading is equal to name label leading // trailing is marginGuide trailing -20 pts detailLabel.topAnchor.constraint(equalTo: nameLabel.bottomAnchor, constant: 5.0), detailLabel.leadingAnchor.constraint(equalTo: nameLabel.leadingAnchor, constant: 0.0), detailLabel.trailingAnchor.constraint(equalTo: marginGuide.trailingAnchor, constant: -20.0), // date label top constrained 5-pts from bottom of detail label // leading is equal to name label leading // trailing is marginGuide trailing dateLabel.topAnchor.constraint(equalTo: detailLabel.bottomAnchor, constant: 5.0), dateLabel.leadingAnchor.constraint(equalTo: nameLabel.leadingAnchor, constant: 0.0), dateLabel.trailingAnchor.constraint(equalTo: marginGuide.trailingAnchor, constant: 0.0), // date label bottom constrained to marginGuide bottom dateLabel.bottomAnchor.constraint(equalTo: marginGuide.bottomAnchor, constant: 0.0), ]) } required init?(coder aDecoder: NSCoder) { fatalError("init(coder:) has not been implemented") } } class BookTableViewController: UITableViewController { override func viewDidLoad() { super.viewDidLoad() tableView.register(BookTableViewCell.self, forCellReuseIdentifier: "BookCell") // use a larger value if we expect rows to usually have multiple lines of text tableView.estimatedRowHeight = 60 } override func numberOfSections(in tableView: UITableView) -> Int { return 1 } override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int { return 10 } override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell { let cell = tableView.dequeueReusableCell(withIdentifier: "BookCell", for: indexPath) as! BookTableViewCell if indexPath.row % 2 == 0 { cell.nameLabel.text = "Row: \(indexPath.row) Name" cell.detailLabel.text = "Row: \(indexPath.row) Detail" cell.dateLabel.text = "Row: \(indexPath.row) Date" } else { cell.nameLabel.text = "Row: \(indexPath.row) Name with\nembedded new-line character." cell.detailLabel.text = "Row: \(indexPath.row) Detail label with enough text that it will need to word-wrap. Height of label will expand as needed." cell.dateLabel.text = "Row: \(indexPath.row) Date" } return cell } } 文件（Linux）中读取二进制代码。当我使用.out时，它在内存地址.read()处停止。我有一个解决方案，要求遍历每个0x1c9内存地址，但是我觉得0x1c9ish应该默认读取整个文件。有谁知道为什么要对我这样做？

下面是读取代码的函数的开头。我相信这就是您所需要的。任何帮助将不胜感激！

.read()
