iphone - Getting the contents of a text field as a number -

i have textfield in app, whre user can enter number (i have set number pad) want store integer in variable writing

int numofyears = [numofyearsfld text]; 

but reason taking incorrectly e.g. if user enters 10, taakes 10214475

am doing wrong ?

intvalue returns int.

integervalue returns nsinteger.

nsinteger numofyears = [[numofyearsfld text] integervalue];
