#chisel的安装常用命令解释和安装常见问题解决

安装 chisel

常见问题

bash: brew: command not found(没有安装brew)

解决方法:
在Terminal中输入 ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)" 安装brew

NO developer tools installed.(没有安装Xcode Command Line Tools)

解决方法:
xcode-select --install  

error: active developer path ("/Applications/Xcode 2.app/Contents/Developer") does not exist, use xcode-select --switch path/to/Xcode.app to specify the Xcode that you wish to use for command line developer tools (or see man xcode-select)(可能安装了多个Xcode)

解决方法:
sudo xcode-select -s /Applications/Xcode.app/Contents/Developer

Error: Could not create /usr/local/Cellar(权限问题,无法创建Cellar文件夹,可以功过磁盘工具修复权限解决也可以手动解决)

解决方法:
1.cd /usr/local
2.sudo mkdir Cellar
3.cd ..
4.chmod 777 /Cellar

常用命令

###pviews

递归打印出所有view,并显示层级关系

sample: pviews 0x7fb8e2fa2e00

 Options:
  --up/-u ; Print only the hierarchy directly above the view, up to its window.
  --depth/-d <depth>; Type: int; Print only to a given depth. 0 indicates
  infinite depth.

Syntax: pviews [--up] [--depth=depth] <aView> 

###pvc

?递归打印出当前所在viewController的层级,可以用于查看viewController结构和定位当前所在的viewController

sample: pvc

 Syntax: pvc <aViewController>

visualize

在预览app中预览UIImageView,CGImageRef,UIView,或CALayer,可用于查看图片详情,大小分辨,文件大小,定位view具体内容等

sample:visualize 0x787b3f00

Arguments:
  <target>; Type: (id); The object to visualize.

Syntax: visualize <target>

mask/unmask & border/unborder

这两组命令用于标识view或layer的位置,mask用来在view上覆盖一个半透明的矩形,border用于给view添加边框,unxxxx是用于解除命令

sample:

• mask 0x787b3f00
• border 0x787b3f00

mask

Options:
  --color/-c <color>; Type: string; A color name such as 'red', 'green',
  'magenta', etc.
  --alpha/-a <alpha>; Type: CGFloat; Desired alpha of mask.

Syntax: mask [--color=color] [--alpha=alpha] <viewOrLayer>

border

Options:
  --color/-c <color>; Type: string; A color name such as 'red', 'green',
  'magenta', etc.
  --width/-w <width>; Type: CGFloat; Desired width of border.

Syntax: border [--color=color] [--width=width] <viewOrLayer>

bmessage

常规添加断点的方法是在xcode中点击添加,但这种添加方式仅限于已经实现的方法添加断点,如果没有实现我们就没法添加断点
使用bmessage可以给没有实现的方法添加断点如:[viewController viewWillAppear:]

sample: bmessage [EmployeeViewController viewWillAppear:]

Arguments:
  <expression>; Type: string; Expression to set a breakpoint on, e.g. "-[MyView
  setFrame:]", "+[MyView awesomeClassMethod]" or "-[0xabcd1234 setFrame:]"

Syntax: bmessage <expression>

caflush

调试时刷新UI布局,不用重新build代码

Syntax: caflush

fv & fvc

通过类名搜送当前内存中的view和viewController实例(支持正则搜索)

sample:

• fv view
• fvc view

fv

Arguments:
  <classNameRegex>; Type: string; The view-class regex to search the view
  hierarchy for.

Syntax: fv <classNameRegex>

fvc

Options:
  --name/-n <classNameRegex>; Type: string; The view-controller-class regex to
  search the view controller hierarchy for.
  --view/-v <view>; Type: UIView; This function will print the View Controller
  that owns this view.

Syntax: fvc [--name=classNameRegex] [--view=view]

taplog

点击屏幕,程序暂停,打印点击的view信息

Syntax: taplog

presponder

打印presponder响应连

sample:presponder self

Arguments:
  <startResponder>; Type: UIResponder *; The responder to use to start walking
