By searching for strings like "NSURLConnection", it would show you piece of code with pinning.
Below are the Steps to Intercept the apps on IOS and Bypassing SSL Pinning.
1) Configure the IOS device (Jailbroken) and auditor laptop on same network. Set the proxy settings in IOS device to point to auditor laptop.
2) Then import the Burpsuite CA certificate to IOS device (Best method is to email cert to device). Then install the certificate on device.
3) Then download the latest release of IOS-SSL-KILLSWITCH (i.e. *.deb file) and copy the same to device. Exit the Cydia before installation of Kill switch (otherwise you get space error).
