See the LLDB-GDB command map ( http://lldb.llvm.org/lldb-gdb.html ) - you have to import a script, and the command is named malloc_info now. 
请参阅LLDB-GDB命令图（ http://lldb.llvm.org/lldb-gdb.html ） - 您必须导入脚本，该命令现在名为malloc_info。 Obviously, malloc stack logging still needs to be turned on in the scheme options. 显然，仍然需要在方案选项中打开malloc堆栈日志记录。
(lldb) script import lldb.macosx.heap
(lldb) malloc_info --stack-history 0x10010d680
Unfortunately, it doesn't show dealloc's - didn't GDBs malloc-history show that as well? 不幸的是，它没有显示dealloc的 - 没有GDBs malloc-history显示那个？

Use instruments, you'll get the exact line - 使用乐器，你会得到确切的线 -
(In XCode) Run it through "Product" -> "Profile". （在XCode中） 通过“Product” - >“Profile”运行它。
This will start Instruments, there you should choose "Zombies" and reproduce the bug event. 这将启动Instruments，你应该选择“Zombies”并重现bug事件。
You'l get a pop-up once a zombie is called, press the chevron to see the exact line . 一旦调出一个僵尸，你会弹出一个弹出窗口， 按下V形符号查看确切的线条 。
Problem is usually a bad __bridge (optional bridges __brige_retained / __bridge_transfer / __bridge ) 问题通常是坏__bridge （可选桥__brige_retained / __bridge_transfer / __bridge ）

You used to be able to use the malloc_history command-line tool from a shell and give it the process ID and address of interest. 您以前可以使用shell中的malloc_history命令行工具，并为其提供感兴趣的进程ID和地址。 It appears this command is no longer installed by the latest Xcode's command line tools. 最新的Xcode命令行工具似乎不再安装此命令。 :-( :-(
