上篇說到了添加UIBarButtonItem,接下來說說介面切換;

1、首先我們在剛才的RootViewController中添加一個按鈕用來實現跳轉:

開啟RootViewController.m(我就繼續寫了),添加一個跳轉button:

2、button動作實現,建立一個NewViewController繼承自UIViewController;用pushViewController到navigationController中去;

#import "NewViewController.h"
- (void)nextAction{        NewViewController *NewVC = [[NewViewController alloc] init];    [self.navigationController pushViewController:NewVC animated:YES];    NewVC.title = @"NewViewController";}

點擊button,Back為系統內建按鈕;

如果不想使用系統內建按鈕,我們可以自訂按鈕:

 UIBarButtonItem *backButton = [[UIBarButtonItem alloc] initWithTitle:@"返回"style:UIBarButtonItemStyleDone target:nil action:nil];    self.navigationItem.backBarButtonItem = backButton;

3、title的自訂:

 1 #import "NewViewController.h" 2  3 @interface NewViewController () 4  5 @end 6  7 @implementation NewViewController 8  9 - (void)viewDidLoad {10     [super viewDidLoad];11     // Do any additional setup after loading the view.12 13     UILabel *title = [[UILabel alloc] init];14     title.text = @"標題";15     title.font = [UIFont systemFontOfSize:20];16     [title sizeToFit];17     self.navigationItem.titleView = title;18     19 }

4、如果想放置多個按鈕:

 NSArray *colorArray = @[@"黑", @"白", @"灰"];    UISegmentedControl *segmentCtrl = [[UISegmentedControl alloc] initWithItems:colorArray];    segmentCtrl.selectedSegmentIndex = 1;    segmentCtrl.tintColor = [UIColor redColor];    self.navigationItem.titleView = segmentCtrl;

添加點擊響應事件:

[segmentCtrl addTarget:self action:@selector(segmentAction:) forControlEvents:UIControlEventValueChanged];

- (void)segmentAction:(id)segment{    switch ([segment selectedSegmentIndex]) {        case 0:        {            UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"提示" message:@"您選擇了顏色黑" delegate:self cancelButtonTitle:@"是" otherButtonTitles:@"否", nil];            [alert show];        }            break;        case 1:        {            UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"提示" message:@"您選擇了顏色白" delegate:self cancelButtonTitle:@"是" otherButtonTitles:@"否", nil];            [alert show];                    }            break;        case 2:        {            UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"提示" message:@"您選擇了顏色灰" delegate:self cancelButtonTitle:@"是" otherButtonTitles:@"否", nil];            [alert show];                    }            break;        default:            break;    }}
