This question is quite similar to https://segmentfault.com/q/1010000004486783/a-1020000004487227. I moved my answer here:

Add the shouldAutorotate method in ViewController. The logic inside is roughly as follows:

@implementation ViewController
- (BOOL)shouldAutorotate {
    int32_t i = 1;
    if (i == 1) {
        return NO;
    }
    return YES;
}
@end

If your ViewController is managed in UINavigationController, you need to modify the corresponding behavior of UINavigationController. For example, the implementation idea through Category is roughly as follows:

#import "UINavigationController.h"
@implementation UINavigationController (Overrides)
- (BOOL)shouldAutorotate {
    id currentViewController = self.topViewController;
    if ([currentViewController isKindOfClass:[<#your-vc#> class]]) {
        int32_t i = 1; 
        if (i == 1) {
            return NO;
        }
        return YES;
    }
    return YES;
}
@end
