使用LLDB命令，在提示的方法上面，下内存断点 (LLDB) b -[__NSPlaceholderDictionary initWithObjects:forKeys:count:]; 即可断下来，原来是：请求的dict中lastGetTime是从缓存中取的，第一次是nil
第2个解决的问题:
NSLog打印一个长度为0的数组
报错:NSRangeException> -[__NSCFString deleteCharactersInRange:]: Range or index out of bounds 解决办法: 由于没有step into的概念,所以一直没有找到问题 最后,打了一个内存断点,才找到问题所在, b -[__NSCFString deleteCharactersInRange:] 原来是,用了一个NSArray的分类,美化打印效果,结果在打印的时候,没有对空数组作验证导致崩溃 |

Interactively search for a view by walking the hierarchy.
Arguments:
<view>; Type: UIView*; The view to border.
Syntax: vs <view>
This command is implemented as FBViewSearchCommand in /usr/local/Cellar/chisel/1.3.0/libexec/commands/FBFlickerCommands.py.
(LLDB adds the next line, sorry...)
Syntax: vs
(lldb) vs sender
Use the following and (q) to quit.
(w) move to superview
(s) move to first subview
(a) move to previous sibling
(d) move to next sibling
(p) print the hierarchy
