A Lot of Functions are deprecated - iOs 6

Question

    [self presentModalViewController:pNewController animated:YES];  presentModalViewController:animated is deprecated since iOs 6   Autosynthesized property 'String' will use synthesized instance variable '_String', not existing instance variable 'String'  Autosynthesized property 'phonenumber' will use synthesized instance variable '_phonenumber', not existing instance variable 'phonenumber'    Deprecated: Group Table View Background Color is deprecated in iOS 6.0. 

Could anyone help me how to fixed it so there wont be any deprecated functions in my project.

Thanks in Advance

Answer 1

[self presentModalViewController:pNewController animated:YES]; 

can be replaced by

[self presentViewController:pNewController animated:YES completion:nil]; 

The background of this change can be seen on WWDC 2012 video session #236, the evolution of view controllers on iOS.

Answer 2

click on the method which is deprecated. in the right column Quick Help inspector you can see the Quick Help from the Apple docs.
There is also a recommandation to use updated or alternate methods.
