[IOS]Setting Bundle + StoryBoard

用storyboard添加一个导航栏，其中首页有一个switch，与setting联动，还有一个button，使用modal连接另一个viewControl，其上也有一个按钮，按下销毁本viewControl，回到前一页。

实现步骤：

1.创建一个SingleView的项目，勾选上storyboard。

2.向storyboard中添加一个NavigationController，两个ViewController，然后在NavigationController中右击指向第一个ViewController，然后设置为rootViewController，并且将箭头指向NavigationController。

3.将两个ViewController的Class分别设置为DXWViewController和DXWViewController1（两个自己创建的类，继承自ViewController）

4.创建setting文件，并将root.plist保存一个键值对，key改成switch

5.修改DXWViewController(主视图)

DXWViewController.h:

#import <UIKit/UIKit.h>
#import "DXWViewController1.h"
@interface DXWViewController : UIViewController<DXWFlipsideViewControllerDelegate>
- (IBAction)change:(id)sender;
@property (retain, nonatomic) IBOutlet UILabel *label;
@property (retain, nonatomic) IBOutlet UISwitch *switchButton;

- (IBAction)showInfo:(id)sender;

@end

DXWViewController.m:

#import "DXWViewController.h"

@interface DXWViewController ()

@end

@implementation DXWViewController

-(void)viewWillAppear:(BOOL)animated
{
    [self changeData];
}

-(void)changeData
{
    NSUserDefaults *usr = [NSUserDefaults standardUserDefaults];
    NSDictionary *dic = [NSDictionary dictionaryWithObjectsAndKeys:@YES,@"switch", nil];

    [usr registerDefaults:dic];
    ((UILabel *)self.label).text = [usr boolForKey:@"switch"]?@"开":@"关";
    self.switchButton.on = [usr boolForKey:@"switch"];
    //都要写入一下
    [usr synchronize];
}

- (void)viewDidLoad
{
    [super viewDidLoad];
	UIApplication *app = [UIApplication sharedApplication];
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(changeData) name:UIApplicationWillEnterForegroundNotification object:app];
}

- (void)dealloc {
    [self.switchButton release];
    [_label release];
    [super dealloc];
}
//实现协议的方法
- (void)flipsideViewControllerDidFinish:(DXWViewController1 *)controller
{
    [self dismissViewControllerAnimated:YES completion:nil];
}
- (IBAction)change:(id)sender {
    UISwitch *switchButton = sender;
    NSUserDefaults *user = [NSUserDefaults standardUserDefaults];
    [user setBool:switchButton.on forKey:@"switch"];
    [user synchronize];
    ((UILabel *)self.label).text = [user boolForKey:@"switch"]?@"开":@"关";
}
- (IBAction)showInfo:(id)sender {
    UIStoryboard *strBoard = [UIStoryboard storyboardWithName:@"MainStoryboard" bundle:nil];
    DXWViewController1 *controller = [strBoard instantiateViewControllerWithIdentifier:@"DXWViewController1"];
    controller.delegate = self;
    controller.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
    [self presentViewController:controller animated:YES completion:nil];
}
@end

上图中showInfo方法是通过代码的方法实现跳转到下一个view,如果是通过storyboard实现连线的方法然后跳过下一个view是这样实现：

@“Add”是连线的ID

//连线的方法
-(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
    if ([segue.identifier isEqualToString:@"Add"]) {
        DXWViewController1 *controlller = segue.destinationViewController;
        controlller.delegate = self;
    }
}

6.修改DXWViewController1(子视图)

DXWViewController.h:

#import <UIKit/UIKit.h>
@class DXWViewController1;

@protocol DXWFlipsideViewControllerDelegate
- (void)flipsideViewControllerDidFinish:(DXWViewController1 *)controller;
@end
@interface DXWViewController1 : UIViewController
@property (assign, nonatomic) id <DXWFlipsideViewControllerDelegate> delegate;
- (IBAction)done:(id)sender;
@end

DXWViewController.m:

#import "DXWViewController1.h"

@interface DXWViewController1 ()

@end

@implementation DXWViewController1

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {
        // Custom initialization
    }
    return self;
}

- (void)viewDidLoad
{
    [super viewDidLoad];
	// Do any additional setup after loading the view.
}

- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

- (IBAction)done:(id)sender {
    [self.delegate flipsideViewControllerDidFinish:self];
}
@end
