Question

该应用程序最近崩溃，我无法理解崩溃日志。

崩溃只发生在iPhone 5s SDK上：9.1，我无法在模拟器或其他SDK版本的设备上重现它..

我不明白这次崩溃背后的真正原因是什么。有什么想法吗？

Answer 1

SIGSEGV： - 它是一个分段错误。更多详情请见SegmentationFault

以下这些方法存在以下问题： -

public class LoginActivity extends AppCompatActivity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_login); // Some useless code... } }

在loadStandardContentCellOnTableView和调试中放置断点。其他行的堆栈跟踪与apple方法有关。

Answer 2

你的牢房可能是零。

我会建议第一件事，打开NSZombie。

然后尝试nil tableview数据源和委托。

- (void)dealloc {
  self.tableView.delegate = nil;
  self.tableView.dataSource = nil;
  [super dealloc];
}

希望得到这个帮助。

Answer 3

您正在使用不推荐使用的方法将您的单元格出列。不应使用dequeueReusableCellWithIdentifier:，而应使用dequeueReusableCellWithIdentifier:forIndexPath:。
