how do you know "com.apple.wifi.linkdidchange"

[powfulhong]

hi, is there any "com.apple.wifi.***" that shows wifi's state? I found that after the wifi's association succeed， wifi icon would wait for seconds to show in the status bar...how do i know its truly time that everything is ready? wait for your answer...(poor english, sorry)

You mean a notification that is sent when WiFi turns on or turns off?

[powfulhong]

No, just like when android wifi is associating, it has a few states that would broadcast, for example authorization.what I want to know is what notification it will send when iOS wifi is associating. Because I found when association callback returns success, the wifi icon don't appear right now,likely it is doing something.

Try WiFiDeviceClientAssociateAsync with the callback argument.

I did use WiFiDeviceClientAssociateAsync and the callback show wifi was associating successfully . What i confused is why it would wait a few seconds to appear at top-left. And how do you know there is a notification called "com.apple.wifi.linkdidchange"? How can i find others? Thanks.

Run the command strings on a MobileWiFi binary. You should see all the notifications.

I try strings MobileWiFi | grep "com.apple", but it just return ------
com.apple.wifi.manager.available
com.apple.wifi.manager
com.apple.wifid.queue
com.apple.wifi.manager.available
com.apple.wifi.manager
com.apple.wifid.queue
com.apple.wifi.manager.available
com.apple.wifi.manager

com.apple.wifid.queue

is it right???(Though i do think so...)

or can you help me find out all notifications of MobileWiFi?

[davidmurray]

Sorry, not sure how you can find the other notifications. :( Maybe check the wifid binary?

[powfulhong]

can't find the other notifications.....:( i found when the association callback return success, it was actually doing something, for example, getting the ip address.
now i found another problem that even if i enter the wrong pwd, the association would return success but actually associated to a different wifi? How could it be?

And how did you get *.h??? class_dump doesn't get it. I use nm MobileWiFi and find that there are a lot of 'information' that you didn't show in headers...

[davidmurray]

I'm not really sure about the other issue you're experiencing. I don't know everything about the iOS WiFi.

I didn't use class-dump, I manually reverse engineered the functions.
