1.git修改强制覆盖本地 #git
git fetch --all //只是下载代码到本地，不进行合并操作
git reset --hard origin/分支名如master //把HEAD指向最新下载的版本
2.Objective-C 获取当前线程调用栈 #objc
NSArray *callStackSymbols = [NSThread callStackSymbols];
NSLog(@"%@", callStackSymbols);
输出示例：

6.adb获取截图以及xml #adb
# 获取页面元素xml文件
os.system("adb shell uiautomator dump /sdcard/uidump.xml")
os.system(f"adb pull /sdcard/uidump.xml ./sample/init/{case_name}.xml")
# 获取页面截图
os.system("adb shell screencap -p /sdcard/screenshot.png")
os.system(f"adb pull /sdcard/screenshot.png ./sample/init/{case_name}.png")
7.adb拉起app #adb
# 通过package_name及activity_name拉起
def launch_app(package_name, activity_name):
cmd = 'adb shell am start --activity-clear-top -n {}/{}'.format(package_name, activity_name)
os.system(cmd)
# 通过urlscheme拉起
def launch_app_by_urlscheme(urlscheme):
cmd = 'adb shell am start --activity-clear-top \"{}\"'.format(urlscheme)
os.system(cmd)
