Type Method

isSourceTypeAvailable:

Returns a Boolean value indicating whether the device supports picking media using the specified source type.

Declaration

+ (BOOL)isSourceTypeAvailable:(UIImagePickerControllerSourceType)sourceType;

Parameters

sourceType

The source to use to pick an image or movie.

Return Value

YES if the device supports the specified source type; NO if the specified source type is not available.

Discussion

Because a media source may not be present or may be unavailable, devices may not always support all source types. For example, if you attempt to pick an image from the user’s library and the library is empty, this method returns NO. Similarly, if the camera is already in use, this method returns NO.

Before attempting to use an UIImagePickerController object to pick an image, you must call this method to ensure that the desired source type is available.
