If I am correct, you simply want to suppress the warnings.

#pragma GCC diagnostic ignored "-Wdeprecated-declarations"

This is simply to suppress the warnings. In release builds, you should not use any deprecated functions.

EDIT: To suppress specific code that invokes warnings, use :

#pragma clang diagnostic push
#pragma clang diagnostic ignored "-Wdeprecated-declarations"

    [self dismissModalViewControllerAnimated:YES];

#pragma clang diagnostic pop

better replace the deprecated code with the new one instead of supressing, simply replace the line with: [self dismissViewControllerAnimated:NO completion:nil];. This is the better option. – Bikram Thapa May 20 '14 at 10:48
Thanks for your answer.Is there any solution to hide warnings for that particular warnings.I don't want to supress all the warnings in that VC. – Jayaprada May 20 '14 at 10:49
See updated code. Also, unless your deployment target < 5.0, it's suggested to use the newer methods. They are available since iOS 5.x – n00bProgrammer May 20 '14 at 10:53

Thanks, mate. Good job. – Felipe Apr 10 '15 at 14:35
Excellent! I've been looking for this forever. – jestro Sep 27 '15 at 20:57
Apps are not rejected for using deprecated methods?! If they were 75% of all Apps out there would be ejected from the store ;) – Cliff Ribaudo Jan 09 '16 at 19:48
Yes, if it won't make your app crash, it will be never rejected! – softninja Oct 23 '16 at 13:38
Others have mentioned it, but need to mention it again - APPLE WILL NOT REJECT AN APP THAT USES DEPRECATED METHODS. – Gruntcakes Dec 21 '16 at 18:10
This works well for me. Because I am using Api that was deprecated in iOS9. But the newer API does not work with iOS 9. So there is no other solution but to suppress the warnings. – Robert J. Clegg Mar 15 '17 at 08:57

@n00bProgrammer thanks for your answer.

For those of us who still have code that supports earlier versions of iOS, the way I handle such old code is to wrap the older code in a version macro test as well as to suppress the compiler warnings that result.

Note that sometimes a deprecated item generates an implicit conversion warning that needs to be suppressed using "-Wconversion".

    if (SYSTEM_VERSION_LESS_THAN(@"6.0")) {
        #pragma clang diagnostic push
        #pragma clang diagnostic ignored "-Wdeprecated-declarations"
        #pragma clang diagnostic ignored "-Wconversion"
        [controlCenter.label setLineBreakMode:UILineBreakModeWordWrap];
        #pragma clang diagnostic pop
    } else {
        [controlCenter.label setLineBreakMode:NSLineBreakByWordWrapping];
    }

You can find the version checker for older Objective-C code here: SYSTEM_VERSION_LESS_THAN()

You can find the version checker for new Swift and Objective-C code here: Swift and Objective-C version check past iOS 8

use

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

or

[self presentModalViewController:loginController animated:YES];

or

[self dismissViewControllerAnimated:NO completion:nil];
