我正在向我的视图控制器显示以下代码:
UINavigationController* navigation = [[UINavigationController alloc] initWithRootViewController:sessionController];
[self presentViewController:navigation animated:YES completion:^{
}];
在呈现的视图控制器的“ viewDidLoad”方法中,我尝试如下设置“后退按钮”:
UIBarButtonItem *newBackButton =
[[UIBarButtonItem alloc] initWithTitle:@"Test"
style:UIBarButtonItemStyleBordered
target:nil
action:nil];
[self.navigationController.navigationItem setBackBarButtonItem:newBackButton];
静默故障,无异常,无日志,无错误和NO按钮。任何想法将不胜感激!

您可以尝试:
self.navigationItem.leftBarButtonItem = newBackButton
