Question

I have a little problem with adding actions on UITabBarItems. I am not using a TabBarController, just the tabbar with items.

I have tried the following in viewDidLoad:

[_myTabItem performSelectorOnMainThread:@selector(myfunction:) withObject:nil waitUntilDone:NO];

This is causing a Unrecognized Selector sent to instance exception.

Have anyone dealt with similar problem?

Answer 1

[_myTabItem performSelectorOnMainThread:@selector(myfunction:) withObject:nil waitUntilDone:NO];

from the above line of code its is clear that myfunction having an argument , but you are not passing any argument ,you set withObject:nil

Either pass required parameter for myfunction ,or just use simple myfunction { }
