Question

i’ve implemented a transition methood in my app delegate file and from every where in the
code i want to call it in order to make nice and cool transitions. i call her like that

[[[UIApplication sharedApplication] delegate] transFromMainToGalery];

for example.

the problem is that im getting warning which is ok (cause it already got approved by apple)
but i still want to fix it

the error:

‘-transFromMainToGalery’ not found in the protocol

any ideas??

thanks in advance!

Answer 1

In your myAppDelegate.h file, make sure you have:

- (void) transFromMainToGalery;

Then cast the generic app delegate returned by the sharedApplication delegate to your specific app delegate class:

[ (myAppDelegate *)[[UIApplication sharedApplication] delegate] transFromMainToGalery ];

Also include myAppDelegate.h in the header of your various other classes which use this message.

(substitute your app delegate class and file name for “myAppDelegate” as needed)
