Question

I have a tab bar app. During the applicationDidFinishLaunching method I have the app check for some files and then display an alertview if the files exist.

I have all the code working except that the alertview will not appear after the tabBarcontroller is showing.

The sequence of events is

1. splashscreen shows
2. window dims (this tells me the alert is attempting to show)
3. the app pauses (it’s waiting for me to press a button a I have a CFRunloop running.

Any help would be appreciated.

Thanks

Ok,

thanks for the hints but I figured it out.

It needed a performSelectorOnMainThread wait(NO)

[self performSelectorOnMainThread:@selector(checkDownloads) withObject:nil waitUntilDone:NO];

on the main calling function inside applicationDidFinishLaunching:

to get it to work.
