Because there are many reports from other developers who used the same API and faced the similar crash problem with the API, it seems it might be a bug of iOS9.0.
In the case of iOS8.4.1, there is no problem on “Burst Shot”.
So, please don’t use “Burst Shot” under iOS9.0 environment and wait for the update of iOS for a while.
What’s new in V1.50
“Selfy mode” which enable you to start the self timer with one eyed wink and cancel the timer with both eyes wink was added.
When you set “flash On” at “Selfy mode” or using front camera, the display tentatively becomes white instead of the flash light.
At the configuration screen, you can modify the timer duration and other condition for timer start and cancel such as passing your hand over the camera.
However, because the battery consumption for wink detection is high, please pay attention to the consumption when you use the “Selfy mode”.
You can change aspect ratio and photo size individually.
You can set On and Off of the shutter sound or set funny shutter sound at any aspect ratio and photo size.
Because the Low Light Boost is active at any aspect ratio and photo size, you can take a photo without dark display.
In addition to “Burst shots before and after shutter”, “Burst shots after shutter” function which sounds a shutter sound once when you push the shutter and no sound after the shutter On.
This “Burst shots after shutter” function is useful for taking a photo that a small child or a pet looking into the camera.
