导航器的基本运用
1：创建工程。值得的注意的是选Empty Application。
2：创建两个 UIViewController的两个子类first 和second。
3 添加你的应用所要用到的图片和声音等文件
在appdelegat.m中写入，记得加入相应的头文件
// 第一个页面，第一个视图控制器
first *fst=[[first alloc] init];
UINavigationController *n=[[UINavigationController alloc] initWithRootViewController:fst];
//显示第一个页面，并且将该页面的view铺满整个window
self.window.rootViewController=n;
在first.m中写入
#import "first.h"
#import "second.h"
#import<AudioToolbox/AudioToolbox.h>
@interface first ()
{
UIImageView *ff,*gg;
}
@end
@implementation first
- (instancetype)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
// Custom initialization
}
return self;
}
//创建 按钮
-(void)createbutton1
{
UIButton *btn=[UIButton buttonWithType:UIButtonTypeCustom];
btn.frame=CGRectMake(60, 43,30, 30);
[btn setImage:[UIImage imageNamed:@"a0017"] forState:UIControlStateNormal];
[btn addTarget:self action:@selector(didbtn:) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:btn];
UIButton *btn2=[UIButton buttonWithType:UIButtonTypeCustom];
btn2.frame=CGRectMake(115,43, 30, 30);
[btn2 setImage:[UIImage imageNamed:@"i0009"] forState:UIControlStateNormal];
[btn2 addTarget:self action:@selector(didbtn2:) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:btn2];
}
//按钮一的方法：
-(void)didbtn:(UIButton *)sender
{
second *scd=[[second alloc] init];
UIImageView *sk=[[UIImageView alloc] init];
scd.strok=sk;
scd.name = 1;
scd.strok.image=[UIImage imageNamed:@"a0001"];
//将一个新的页面在导航栈中显示出来, 入栈、压栈
//所有已经在导航控制器管理下的页面（UIViewController）都可以通过一个navigationController的属性访问它所在的导航控制器
[self.navigationController pushViewController:scd animated:YES];
}
//按钮二的方法：
-(void)didbtn2:(UIButton *)sender
{
second *scd=[[second alloc] init];
_strok =[[UIImageView alloc] init];
scd.strok=_strok;
scd.name = 2;
scd.strok.image=[UIImage imageNamed:@"i0001"];
[self.navigationController pushViewController:scd animated:YES];
}
//创建的视图
-(void)createview1
{
ff=[[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 320, 480)];
ff.image=[UIImage imageNamed:@"bg_01"];
[self.view addSubview:ff];
gg=[[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 320, 480)];
gg.image=[UIImage imageNamed:@"bg_01_01"];
[self.view addSubview:gg];
}
- (void)viewDidLoad
{
[super viewDidLoad];
[self createview1];
[self createbutton1];
self.navigationController.navigationBarHidden=YES;
// Do any additional setup after loading the view.
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose
of any resources that can be recreated.
}
在second.h中写入
@interface second : UIViewController
@property int name;
@property UIImageView *strok;
@end
在second.m中写入：
#import "first.h"
#import "second.h"
#import<AudioToolbox/AudioToolbox.h>
@interface second ()
{
//定义全局变量
UIImageView *bottomBg,*titleView,*kanaDeta,*stk;
SystemSoundID sound1;
}
@end
@implementation second
- (instancetype)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
// Custom initialization
}
return self;
}
//创建 视图
-(void)creatview2
{
//中间图片
kanaDeta=[[UIImageView alloc] initWithFrame:CGRectMake(0, 44, 320, 418)];
kanaDeta.image=[UIImage imageNamed:@"kanaDeta"];
[self.view addSubview:kanaDeta];
//顶部图片
titleView=[[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 320, 49)];
titleView.image=[UIImage imageNamed:@"titleView"];
[self.view addSubview:titleView];
//底部图片
bottomBg=[[UIImageView alloc ] initWithFrame:CGRectMake(0, self.view.frame.size.height-49, 320, 49)];
bottomBg.image=[UIImage imageNamed:@"bottomBg"];
[self.view addSubview:bottomBg];
}
//创建 按键
-(void)creatbutton2
{
//返回按钮
UIButton *backBtn=[UIButton buttonWithType:UIButtonTypeCustom];
//把按钮放置图片
