Dynamic user interface schemes for an electronic device based on detected accessory devices

An electronic device comprising:

• a display;
• a housing;
• one or more processors;
• memory;
• and
• one or more programs stored in the memory and configured to be executed by the one or more processors and including instructions for:
• detecting an incoming call;
• in response to detecting the incoming call, outputting an incoming call alert, wherein outputting the incoming call alert includes at least one of generating an audible output or generating a haptic output to indicate the presence of the incoming call;
• while the incoming call alert is active, detecting an insertion of the electronic device into a case, wherein at least a portion of the display is covered by the case when the electronic device is in the case;
• in response to detecting the insertion of the electronic device into the case while the incoming call alert is active, ceasing to generate the at least one of the audible output or the haptic output without declining the incoming call;
• after detecting the coupling of a case to the computer system and after ceasing to generate the at least one of the audible output or the haptic output, detecting a decoupling of the case from the computer system;
• in response to detecting the decoupling of the case from the computer system, displaying an accept-call affordance on the display;
• and
• in response to detecting a selection of the accept-call affordance, accepting the incoming call.

A non-transitory computer readable storage medium storing one or more programs, the one or more programs comprising instructions, which when executed by an electronic device having a display, cause the electronic device to:

• detect an incoming call;
• in response to detecting the incoming call, output an incoming call alert, wherein outputting the incoming call alert includes at least one of generating an audible output or generating a haptic output to indicate the presence of the incoming call;
• while the incoming call alert is active, detect an insertion of the electronic device into a case, wherein at least a portion of the display is covered by the case when the electronic device is in the case;
• in response to detecting the insertion of the electronic device into the case while the incoming call alert is active, cease generating the at least one of the audible output or the haptic output without declining the incoming call;
• after detecting the coupling of a case to the computer system and after ceasing to generate the at least one of the audible output or the haptic output, detect a decoupling of the case from the computer system;
• in response to detecting the decoupling of the case from the computer system, display an accept-call affordance on the display;
• and
• in response to detecting a selection of the accept-call affordance, accept the incoming call.
