When I open the installed application, I find that the "Untrusted Developers" dialog box pops up, and even more amazing is that there is only a cancel option. what am I supposed to do？ I'm at a loss.

2, according to his prompt, find the settings, and then vaguely remember that when installing pp assistant, there is a "profile" setting item, which seems to be a management matter.

3. I opened the general description file and found a similar setting option.

4. Click the corresponding option to enter. Because I am debugging my real machine, I choose the developer to click on the list bar of my appleid to edit the trust option.

5. The 5.ios system will foolishly ask you if you trust your application to run on your own machine. I chose trust without hesitation.

6. After trust, I found that the middle column "Information (my Apple account or other developers)" became "Delete application", indicating that the trust configuration was successful.

7. Now you can press the Home button to return to the desktop, open the application, and test and use it.
