我的导航栏上有两个按钮。一个在左边,一个在右边。左侧的按钮有效,但右侧的按钮无效。如果我交换按钮,重新编译并加载问题仍然存在右侧按钮,无论哪个按钮位于条形图的正确位置。

此外,当我尝试使用右按钮时左按钮工作,左按钮也停止工作。

如何使右键工作?以下是代码。

UINavigationBar *NavBar = [[UINavigationBar alloc] init];
[NavBar sizeToFit];
[self.view addSubview:NavBar];
UIBarButtonItem *cmdBack = [[UIBarButtonItem alloc] initWithTitle:@"Back"
                                                            style:UIBarButtonItemStyleBordered
                                                           target:self
                                                           action:@selector(cmdBackClicked:)];
UIBarButtonItem *cmdAddDevice = [[UIBarButtonItem alloc] initWithTitle:@"Add Device"
                                                                 style:UIBarButtonItemStyleBordered
                                                                target:self
                                                                action:@selector(cmdAddDeviceClicked:)];
UINavigationItem *NavBarItems = [[UINavigationItem alloc] initWithTitle:@"Settings"];
NavBarItems.leftBarButtonItem = cmdBack;
NavBarItems.rightBarButtonItem = cmdAddDevice;
NavBar.items = [NSArray arrayWithObjects:NavBarItems, nil];

按钮的功能是这些

- (void) cmdBackClicked:(id)sender
{
    [self.view removeFromSuperview];
}

- (void) cmdAddDeviceClicked:(id)sender
{
    vcAddDevice *ViewAddDevice = [[vcAddDevice alloc] initWithNibName:@"vcAddDevice"     bundle:nil];
    [ViewAddDevice SetEditDeviceMode:[NSString stringWithFormat:@"No"]];
   [self.view addSubview:ViewAddDevice.view];
}

在.h文件中我有这个。

#import <UIKit/UIKit.h>
#import "vcAddDevice.h"

@interface ViewControllerSettings : UIViewController<vcAddDeviceControllerDelegate, UITableViewDelegate, UITableViewDataSource>

- (IBAction) cmdBackClicked:(id) sender;
- (IBAction) cmdAddDeviceClicked:(id) sender;

@end
