iphone开发：构建软件的设置页面

 

今天建立一个 iPhone app，运用 Settings Bundle 设置运行程序

纲要：
－在程序显示前运行代码；
－UILabel的运用；
－把 Settings Bundle 加入程序；

首先运行以安装好的 xCode

选择: File->New Project. 从 "New Project" 窗口
 
选择 : iPhone OS ->Applications-> View-Based Application
命名 : 这里命名为 "SettingsBundle"

(1)  在 xCode 打开 File -> New File.. ；

选择 Settings Bundle; 命名为 Settings.bundle;

 

 

(2)  在 Setting.bundle 双击  Root.plist

把 PrefernceSpecifiers 前的三角向下，按下，加入：

Item1,

Item2,

Item3,

Item4,

Item5,

Item6,

 

在 xCode 打开 File -> Save；

 

(3)  在xCode 打开 SettingBundleViewController.h 文件,加入代码

#import <UIKit/UIKit.h>

@interface SettingsBundleViewController : UIViewController {
    
    IBOutlet UILabel *lblText;
    IBOutlet UILabel *lblReadOnly;
    IBOutlet UILabel *lblSlider;
    IBOutlet UILabel *lblColor;
    IBOutlet UILabel *lblToogle;
}

@property (nonatomic, retain) UILabel *lblText;
@property (nonatomic, retain) UILabel *lblReadOnly;
@property (nonatomic, retain) UILabel *lblSlider;
@property (nonatomic, retain) UILabel *lblColor;
@property (nonatomic, retain) UILabel *lblToogle;

@end

(4)  在xCode打开 SettingsBundleViewController.m 文件,加入下面代码

#import "SettingsBundleViewController.h"

@implementation SettingsBundleViewController

// The designated initializer. Override to perform setup that is required before the view is loaded.
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil {
    if (self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil]) {
        // Custom initialization
    }
    return self;
}
// Implement viewDidLoad to do additional setup after loading the view, typically from a nib.
- (void)viewDidLoad {
    NSString *textValue = [[NSUserDefaults standardUserDefaults] stringForKey:@"textEntry_key"];
    NSString *readOnlyValue = [[NSUserDefaults standardUserDefaults] stringForKey:@"readOnly_key"];
    NSString *sliderValue = [[NSUserDefaults standardUserDefaults] stringForKey:@"slider_key"];
    NSString *colorValue = [[NSUserDefaults standardUserDefaults] stringForKey:@"colors_key"];
    NSString *toogleValue = [[NSUserDefaults standardUserDefaults] stringForKey:@"toogle_key"];
   
    lblText.text = [NSString stringWithFormat:@"Text Value: %@", textValue];
    lblReadOnly.text = [NSString stringWithFormat:@"Read Only Value: %@", readOnlyValue];
    lblSlider.text = [NSString stringWithFormat:@"Slider Value: %@", sliderValue];
    lblColor.text = [NSString stringWithFormat:@"Selected color value: %@", colorValue];
    lblToogle.text = [NSString stringWithFormat:@"Toggle Control Value: %@", toogleValue];
   
}
// Override to allow orientations other than the default portrait orientation.
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
    // Return YES for supported orientations
    return (interfaceOrientation == UIInterfaceOrientationPortrait);
}

- (void)didReceiveMemoryWarning {
    [super didReceiveMemoryWarning]; // Releases the view if it doesn't have a superview
    // Release anything that's not essential, such as cached data
}

- (void)dealloc {
    [lblToogle release];
    [lblText release];
    [lblReadOnly release];
    [lblSlider release];
    [lblColor release];
    [super dealloc];
}
@end

(5) UIView 界面设置

双击文件： "SettingsBundleViewController.xib" ；

然后 "Interface Builder"  会自动打开，在这里我们可以编辑改变界面
 
选择： Tools -> Reveal In Document Window -> View

选择:  Tools -> Attributes Inspector

在色条内选择 "白色"，可以看到背景变为黑色

(3) 加入 五个 Label

选择: Tools -> Label ； 从Library显示菜单中拖拉一个 Label 到 Main View
在 Interface Builder

在主视窗口或文件窗口；点击 Label

选择: Tools -> Connection Inspector

移动鼠标在"Touch Up Inside" 后面圆圈上; 圆圈变为(+); 拖向直线连接到"File's Owner";
放开鼠标选择键出现 "lblText"; 选上它。

其余四个label步骤同上分别选上 “lblReadOnly”,”lblSlider”,”lblToogle”,”lblColor”

选择： File -> Save then close Interface Builde 

最后在 xCode 选择 Build -> Build and Go
