Reveal APP（有源码）

在有源码的情况下使用Reveal查看自己APP界面层次，可使用以下步骤实现

1.下载Reveal （下载地址：https://pan.baidu.com/s/1sjNySjz）
2.找到Reveal动态库

取Reveal库.png

3.把动态库添加到工程中（注意不要勾选target）

添加到project.jpeg
4.把动态库添加到bundle Resource
添加到bundle Resource_1.jpeg 添加到bundle Resource_2.jpeg 添加到bundle Resource_完成.jpeg

5.添加系统库

添加系统库.jpeg

6.添加脚本（下面途中第二个复选框不要勾）

添加脚本.jpeg

脚本源码：

set -e

if [ -n "${CODE_SIGN_IDENTITY}" ]; then

codesign -fs "${CODE_SIGN_IDENTITY}" "${BUILT_PRODUCTS_DIR}/${FULL_PRODUCT_NAME}/libReveal.dylib"

fi

7.在

• (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions函数中加载reveal动态库
