iOS 純程式碼設定導航欄上建立左按鈕右按鈕
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
//1、建立視窗
self.window = [[UIWindowalloc]initWithFrame:[[UIScreenmainScreen]bounds]];
self.window.backgroundColor = [UIColorwhiteColor];
//2.建立一個導航控制器並新增子檢視
UINavigationController *nav = [[
//nav.navigationBar.barTintColor = [UIColor redColor];
[nav.navigationBarsetBackgroundImage:[UIImageimageNamed:@"00"]forBarMetrics:UIBarMetricsDefault];
//3.設定根檢視
self.window.rootViewController = nav;
//4、顯示視窗
[self
returnYES;
}
其次在ViewController.m檔案裡面去定製導航欄左右按鈕，以及中間標題- (void)viewDidLoad {
[superviewDidLoad];
//定製標題
//方式2：
UILabel *titleLab = [[UILabelalloc]initWithFrame:CGRectMake(0,20, 80, 44)];
titleLab.text =@"通訊錄";
titleLab.textColor = [UIColorwhiteColor];
titleLab.
self.navigationItem.titleView = titleLab;
//定製右按鈕
UIButton *but = [UIButtonbuttonWithType:UIButtonTypeCustom];
but.frame =CGRectMake(0,0, 60, 44);
[but setTitle:@"下一頁"forState:UIControlStateNormal];
[but addTarget:selfaction:@selector(Next:)forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem *barBut = [[UIBarButtonItemalloc]initWithCustomView:but];
self.navigationItem.rightBarButtonItem = barBut;
//定製左按鈕
UIButton *but = [UIButtonbuttonWithType:UIButtonTypeCustom];
but.frame =CGRectMake(0,0, 60, 44);
[but setTitle:@"<返回"forState:UIControlStateNormal];
[but addTarget:selfaction:@selector(popView:)forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem *barBut = [[UIBarButtonItemalloc]initWithCustomView:but];
self.navigationItem.leftBarButtonItem = barBut;
}//左按鈕事件響應函式
-(IBAction)Next:(id)sender{
}
//右按鈕事件響應函式
-(IBAction)popView:(id)sender{
}
