How to persist different Slider Value in ImageProcessing App??

[muzammil]

Hi All,


I am working on one iPad image processing app. In which i have 14 different sliders for different operation like changing Brightness, Contrast, Hue, applying Vignette, Blur, Tilt etc. Everything is working perfectly independently.

But my issue is how to persist the state of all slider. i.e. suppose user select Brightness slider and change the brightness of image then go to Hue slider and change the hue and then again go back to Brightness slider then there should be last applied Brightness can change. Currently what i am doing, I am saving the image when user apply any effect. An applied Brigtness image pass into Hue so user come back to brightness a new brightness become applied on image.

Please give me some idea how can i persist these slider value.


Thanks in advance

i think you need to persist the value only for the duration of the editing, don't make sense to persist when your user close the app, open it after 2-3 days and edit the same image......

I am asking only about persisting the value at running time of app.
