ios开发中 应用设置的简单开发 (Settings.bundle)

文章转自  http://blog.csdn.net/iunion/article/details/7067544

1.首先创建iPhone应用工程

2.新建Settings Bundle文件

菜单->File->New->New File...

选择Settings Bundle创建文件，见上图

选中Root.plist并将Preference Items打开

这个编辑器很不好用，建议使用Source Code来编辑，在Root.plist文件上按鼠标右键，如下图

3.编辑Root.plist

具体的编辑就不写了，主要需要注意

“Default Value”项最好填写上，作为默认值初始化用

4.编写程序

首先修改ViewController.h

 #import <UIKit/UIKit.h>

 @interface ViewController : UIViewController
 {
     IBOutlet UILabel *lblTite;
     IBOutlet UILabel *lblText;
     IBOutlet UILabel *lblToogle;
     IBOutlet UILabel *lblSlider;
     IBOutlet UILabel *lblBackground;
 }

 @property (nonatomic, retain) UILabel *lblTite;
 @property (nonatomic, retain) UILabel *lblText;
 @property (nonatomic, retain) UILabel *lblSlider;
 @property (nonatomic, retain) UILabel *lblToogle;
 @property (nonatomic, retain) UILabel *lblBackground;

 @end

修改ViewController.m

 @synthesize lblTite,lblText,lblToogle,lblSlider,lblBackground;


 - (void)viewDidLoad
 {
     [super viewDidLoad];
     // Do any additional setup after loading the view, typically from a nib.

     NSString *titeValue = [[NSUserDefaults standardUserDefaults] stringForKey:@"title_preference"];
     NSString *textValue = [[NSUserDefaults standardUserDefaults] stringForKey:@"text_preference"];
     NSString *toogleValue = [[NSUserDefaults standardUserDefaults] stringForKey:@"enabled_preference"];
     NSString *sliderValue = [[NSUserDefaults standardUserDefaults] stringForKey:@"slider_preference"];
     NSString *backgroundValue = [[NSUserDefaults standardUserDefaults] stringForKey:@"backgroud_preference"];

     lblTite.text = [NSString stringWithFormat:@"Title Value: %@", titeValue];
     lblText.text = [NSString stringWithFormat:@"Text Value: %@", textValue];
     lblToogle.text = [NSString stringWithFormat:@"Toggle Control Value: %@", toogleValue];
     lblSlider.text = [NSString stringWithFormat:@"Slider Value: %@", sliderValue];
     lblBackground.text = [NSString stringWithFormat:@"Selected color value: %@", backgroundValue];
 }

修改AppDelegate.m

 // 获取默认设置
 - (void)registerDefaultsFromSettingsBundle
 {
     NSString *settingsBundle = [[NSBundle mainBundle] pathForResource:@"Settings" ofType:@"bundle"];
     if(!settingsBundle) {
         NSLog(@"Could not find Settings.bundle");
         return;
     }

     NSDictionary *settings = [NSDictionary dictionaryWithContentsOfFile:[settingsBundle stringByAppendingPathComponent:@"Root.plist"]];
     NSArray *preferences = [settings objectForKey:@"PreferenceSpecifiers"];

     NSMutableDictionary *defaultsToRegister = [[NSMutableDictionary alloc] initWithCapacity:[preferences count]];
     for(NSDictionary *prefSpecification in preferences) {
         NSString *key = [prefSpecification objectForKey:@"Key"];
         if(key) {
             [defaultsToRegister setObject:[prefSpecification objectForKey:@"DefaultValue"] forKey:key];
         }
     }
     [[NSUserDefaults standardUserDefaults] registerDefaults:defaultsToRegister];
     //[defaultsToRegister release];
 }


 - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
 {
     // Override point for customization after application launch.

     NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
     NSString *title = [defaults stringForKey:@"title_preference"];
     if(!title) {
         // 加载默认配置
         [self performSelector:@selector(registerDefaultsFromSettingsBundle)];
     }
     return YES;
 }
