iphone - Unable to access method in the delegate -

-

here's how set app. have root view loads subview on top of during viewdidload method. in subview have button that, when clicked, hides , reveals root view. working great, hate having view loaded not in use. tried put method in delegate this:

[thelaunch release];

...where thelaunch subview.

this method, located in delegate, called hidethelaunch.

then trying call method within subview:

[[uiapplication sharedapplication].delegate hidethelaunch];

but says -hidethelaunch not found in protocol.

am doing wrong?

thanks in advance!

you need first cast uiapplicationdelegate specific delegate's type:

[((myappdelegate *) [uiapplication sharedapplication].delegate) hidethelaunch];
