Global Variable

AVCaptureMaxAvailableTorchLevel

Declaration

const float AVCaptureMaxAvailableTorchLevel;

Discussion

This constant always represents the maximum available torch level, independent of the actual maximum value currently supported by the device. Thus, pass this constant to the setTorchModeOnWithLevel:error: in situations where you want to specify the maximum torch level without having to worry about whether the device is overheating and might not accept a value of 1.0 as the maximum.
