1.在当前用户目录新建一个文件.lldbinit，位于~/.lldbinit，LLDB每次启动的时候都会加载这个文件。
2.在.lldbinit中输入如下内容（只能在模拟器使用）：
command script import "~/Library/Application Support/Realm/rlm_lldb.py" --allow-reload
display @import UIKit
target stop-hook add -o "target stop-hook disable"
command script import /usr/local/opt/chisel/libexec/fblldb.py
command alias polayout po (id)[[UIWindow keyWindow] _autolayoutTrace]
command alias reveal_load expr (Class)NSClassFromString(@"IBARevealLoader") == nil ? (void *)dlopen("/Applications/Reveal.app/Contents/SharedSupport/iOS-Libraries/libReveal.dylib", 0x2) : ((void*)0)
command alias reveal_load_swift expr NSClassFromString("IBARevealLoader") == nil ? dlopen("/Applications/Reveal.app/Contents/SharedSupport/iOS-Libraries/libReveal.dylib", 2) : dlopen("", 0)
command alias reveal_start expr (void)[(NSNotificationCenter*)[NSNotificationCenter defaultCenter] postNotificationName:@"IBARevealRequestStart" object:nil];
3.oc下在appdelegateload里面断点，输入“ reveal_load”，swift输入“ reveal_load_swift”
