从UIViewController呈现UINavigationController

Question

CurrentViewController.h

#import <UIKit/UIKit.h>
#import "nextNavViewController.h"
@interface CurrentViewController : UIViewController 

{
nextNavViewController *contr;
}
- (IBAction)showNavView:(id)sender;

@end

CurrentViewController.m

/*..........*/
- (IBAction)showNavView:(id)sender {
    contr = [[nextNavViewController alloc]initWithNibName:@"nextNavViewController"bundle:nil];
    [self presentViewController: contr animated:YES completion:nil];


}
/* ......... */

nextNavViewController.h

#import <UIKit/UIKit.h>

@interface nextNavViewController : UINavigationController

@end

我有“nextNavViewController.xib”，其中包含一个表格，一些按钮和自定义导航栏。我希望加载此接口，但它加载空白屏幕的空白导航栏。

我做的事情可能吗？我需要做什么才能加载自定义界面？

Answer 1

有几件事：

1）小心你的课程名称。确保他们遵循objective-c standards

2）您不需要对UINavigationController进行子类化。如果您想获得UINavigationController的一些功能，只需：

contr = [[nextNavViewController alloc]initWithNibName:@"nextNavViewController"bundle:nil];

UINavigationController *myNavigation = [[UINavigationController alloc] initWithRootViewController:contr];

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