第五章，我想仿照做着，把辅助功能里面的小圆点功能逆向，然后放到sbseting设置下面，遇到了一些问题

我找到了对应Plist文件，然后也修改了一些值，书中使用通知，然后就解决了，我发了通知没用，根据截取到的通知，我xm文件代码如下：
%orig;
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@“第二次” message:nil delegate:self cancelButtonTitle:@“OK” otherButtonTitles:nil];
[alert show];
NSMutableDictionary *dictionary = [NSMutableDictionary dictionaryWithContentsOfFile:@"/var/mobile/Library/Preferences/com.apple.Accessibility.plist"];

[dictionary setObject:[NSNumber numberWithInt:1] forKey:@"AssistiveTouchEnabled"];
[dictionary setObject:[NSNumber numberWithInt:1] forKey:@"AccessibilityEnabled"];
[dictionary setObject:[NSNumber numberWithInt:1] forKey:@"AssistiveTouchUIEnabled"];

[dictionary writeToFile:@"/var/mobile/Library/Preferences/com.apple.Accessibility.plist" atomically:YES];
notify_post("com.apple.accessibility.asssistive.touch.status");
notify_post("com.apple.accessibility.status");
notify_post("com.apple.accessibility.cache.ast");
notify_post("com.apple.accessibility.cache.ax");

然后make page install 后，发现 设置里面选项是改了（说明Plist改对了），但是，小圆点没有出来，然后我就没有思路了， 谁能告诉我，还有什么思路我继续往下搞，谢谢了。

其实我就想实现，把辅助功能里面的小白点，功能暴露出来

3

一步一个坑呀 yumen

4

没人吗？难道我问得太难了？

5

一个人也没 哎

6

会不会是plist的配置改后，还要通知下系统重新加载下。继续找找如何通知系统重新加载的方法。（猜测）

7

已经找了， 使用 狗神的，拦截通知，然后把看着像的 通知都发了一遍，_UIWindowSystemGestureStateChangedNotification这个通知没有发，但是感觉不是这个通知,然而还是没有用

8

自己继续顶

9

给个意见也行

10

你逆向看看啊，我在书上举的我早期的一个例子，就是改配置文件然后发通知，但不推荐这么做，肯定有更优雅的解决方案

您就是传说中的作者呀。
明白了，那我就不纠结这个问题，继续往下学了，找到更好的方法的时候再来看看
