It looks like there is some sort of setup that prevents the button click action being called in ‘viewDidLoad’ – at least, I did it, but it didn’t work. Is anyone aware of an application or view delegate method in which instantiating the UIImagePickerController would work?

Do you (or any of the commenters here) have a sample or tutorial that shows you how to make an app that just uses the LED on the iPhone 4? I want to create a flashlight app with strobing….

Thanks

You will need to update the build settings to match your developer credentials.

Hi there.

Tried to run the app, but every time I build, I get the “The executable was signed with invalid entitlements.” error.

I am a paid developer, so something is wrong with the zipped file.

Hi John,

This is what I am searching for. Thank you for this page.

Charles, you do need to release the imagePicker to keep from creating a leaked object.

Where do you dealloc memory for the imagePicker? Do you find any leaks if you activate the camera multiple times?

JMT, interesting idea, I’m not sure off hand how to overlay an image on the camera (or if it’s possible). Anyone have any ideas?

Fantastic work – I’ve been struggling with the Apple docs on this topic and your code was great bootstrap for me.

Can you point me in the direction of a technique which will allow me to overlay or superimpose a frame or other “border” image while the camera is active and save the “merged” image?

Thanks in advance.

Hi Alan,

If you download the source code for the project you can see how I use the code shown above in a complete working example. That is probably a good starting point in which you can modify the code to see how things work.

Hope that helps.
