从详细视图禁用/启用后退按钮

Question

如何从详细视图控制器中禁用后退按钮？

Answer 1

根据您的配置:

self.navigationItem.hidesBackButton = YES;

要么:

self.navigationController.navigationItem.hidesBackButton = YES;

或者,如果您只想在不隐藏按钮的情况下禁用该按钮,则可以使用此按钮.

self.navigationController.navigationItem.backBarButtonItem.enabled = NO;

Answer 2

您可以使用UINavigationItem hidesBackButton来隐藏它:

self.navigationItem.hidesBackButton = YES;
