# 21.Cycrupt用法

## 一、动态调试

![1](/files/-MaNQBPaXZdN-jEsifxp)

这里我通过Cycript修改了微信语言选择按钮的文案。

### 1.1 choose

```cpp
cy# choose(UILabel)
[#"<UIButtonLabel: 0x111f48ca0; frame = (70 12.6667; 37 22); text = '\xe7\x99\xbb\xe5\xbd\x95'; opaque = NO; userInteractionEnabled = NO; layer = <_UILabelLayer: 0x280c9b700>>",#"<UIButtonLabel: 0x111f674f0; frame = (70 12.6667; 37 22); text = '\xe6\xb3\xa8\xe5\x86\x8c'; opaque = NO; userInteractionEnabled = NO; layer = <_UILabelLayer: 0x280c8a530>>",#"<UIButtonLabel: 0x111f78250; frame = (15 16; 58 17); text = '\xe7\xae\x80\xe4\xbd\x93\xe4\xb8\xad\xe6\x96\x87'; opaque = NO; userInteractionEnabled = NO; layer = <_UILabelLayer: 0x280c8aa30>>",#"<MMUILabel: 0x111f89350; baseClass = UILabel; frame = (0 0; 0 36); userInteractionEnabled = NO; layer = <_UILabelLayer: 0x280cf1ef0>>",#"<MMUILabel: 0x111f8c750; baseClass = UILabel; frame = (0 0; 0 36); userInteractionEnabled = NO; layer = <_UILabelLayer: 0x280cf2ad0>>",#"<UILabel: 0x111f8e430; frame = (0 0; 0 0); userInteractionEnabled = NO; layer = <_UILabelLayer: 0x280cf3890>>",#"<UILabel: 0x111c36770; frame = (0 0; 0 0); userInteractionEnabled = NO; layer = <_UILabelLayer: 0x280cc9720>>"]
```

### 1.2 设置值

```cpp
cy# #0x111f78250.text = @"Ryukie"
@"Ryukie"
```

## 二、高级用法

### 2.1 cy封装

#### APPID

```cpp
cy# APPID
@"cn.Ryukie.Sama.Hanoi"
```

#### pvcs

```cpp
cy# pvcs()
"<MMUINavigationController 0x1120d5a00>, state: appeared, view: <UILayoutContainerView 0x111c0e060>\n   | <WCAccountLoginFirstViewController 0x11292d400>, state: appeared, view: <UIView 0x111c1c680>"
```

> 这些其实都是封装好的一些.cy文件。再拷贝进包中。

### 2.2 自定义cy

```cpp
➜  Cy touch Ryukie.cy
➜  Cy vim Ryukie.cy
➜  Cy cat Ryukie.cy
sum = function(a,b) {
    return a + b;
}
```

#### a. 添加到工程中

![2](/files/-MaNQBPbtYvvQXvlO1b8)

#### b. 添加Copy

![3](/files/-MaNQBPcr8gRo0znpXDU)

#### c. 运行工程，链接cy

```cpp
➜  Cy sh cyWifiLogin.sh // 这里是封装了链接的脚本
cy# @import Ryukie
{}
cy# sum(1,3)
4
```
