ios - Saving pictures to parse -
my project save data parse , while can pick image library cannot open camera. found tutorial not compatible code. link tutorial here: tutorial . using .storyboard , tutorial .xib, not know if change anything.
my .m file here:

take @ apple's provided sample project (especially aplviewcontroller.m)
you'll see them following 4 steps. doing last half of step one, without first verifying if source type available.
from uiimagepickercontroller class reference:
to use image picker controller containing default controls, perform these steps:
verify device capable of picking content desired source. calling issourcetypeavailable: class method, providing constant “uiimagepickercontrollersourcetype” enumeration. check media types available, source type you’re using, calling availablemediatypesforsourcetype: class method. lets distinguish between camera can used video recording , 1 can used still images. tell image picker controller adjust ui according media types want make available—still images, movies, or both—by setting mediatypes property. present user interface. on iphone or ipod touch, modally (full-screen) calling presentviewcontroller:animated:completion: method of active view controller, passing configured image picker controller new view controller.
