DAY SEVEN – Settings Bundle

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
