save - saving switch position and load data in another view controller -

i building app witch automatically generates email different chosen options user of app. have 3 view controllers each 10 / 15 different options. user has possibility choose different options sliding switches on/off. switch changes label "chosen option a" or "not chosen option a" when selected off. when change viewcontroller while testing, switches go standard off position when going viewcontroller. chosen position not stored in app. means text in labels go wrong text (not chosen option)

first question: how can store switch position text stays user has chosen? without separate safe button , how automatically reload these settings while opening view controller?

then, possible generate text these labels 1 textfield or textviewer on separate viewcontroller? example named page "email" user has possibility @ text in text box (textfield or text viewer) , has possibility add command these texts.

i have created email function generates email app including receiver, subject , message body.

please make answers easy/clear possible because new in programming ios app's. prefer example codes use.

thanks answer(s) , sorry bad english.

with kind regards,

tim
