使用XIB实现一个简单view

1. AppDelegate

AppDelegate.h 文件

#import <UIKit/UIKit.h>

@interface AppDelegate : UIResponder <UIApplicationDelegate>

@property (strong, nonatomic) UIWindow *window;

@property (strong, nonatomic) UITabBarController *tabBarController;

@end

AppDelegate.m 文件

#import "AppDelegate.h"

#import "ViewController.h"

#import "AZImageViewController.h"

@interface AppDelegate ()

@end

@implementation AppDelegate

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {

    self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];

//    ViewController *viewController = [[[ViewController alloc] initWithNibName:@"ViewController" bundle:nil] autorelease];

//    self.window.rootViewController = viewController;

    ViewController *viewController = [[[ViewController alloc] initWithNibName:@"ViewController" bundle:nil] autorelease];

    AZImageViewController *imageViewController = [[[AZImageViewController alloc] initWithNibName:@"AZImageViewController" bundle:nil] autorelease];

    self.tabBarController = [[UITabBarController new] autorelease];

    self.tabBarController.viewControllers = @[viewController, imageViewController];

    self.window.rootViewController = self.tabBarController;

    [self.window makeKeyAndVisible];

    return YES;

}

- (void)dealloc

{

    [_window release];

    [super dealloc];

}

@end

---

2. ViewController

ViewController.h 文件

#import <UIKit/UIKit.h>

@interface ViewController : UIViewController

@property (retain, nonatomic) IBOutlet UILabel *status;

- (IBAction)leftButtonPress:(id)sender;

- (IBAction)rightButtonPress:(id)sender;

- (IBAction)setStatusText:(id)sender;

@end

ViewController.m 文件

#import "ViewController.h"

@interface ViewController ()

@end

@implementation ViewController

@synthesize status;

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil {

    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];

    if (self) {

        self.title = NSLocalizedString(@"First", @"First");

        self.tabBarItem.image = [UIImage imageNamed:@"first"];

    }

    return self;

}

- (void)viewDidLoad {

    [super viewDidLoad];

    // Do any additional setup after loading the view, typically from a nib.

}

- (void)didReceiveMemoryWarning {

    [super didReceiveMemoryWarning];

    // Dispose of any resources that can be recreated.

}

- (void)dealloc {

    [status release];

    [super dealloc];

}

- (IBAction)leftButtonPress:(id)sender {

     status.text = @"this is left btn";

}

- (IBAction)rightButtonPress:(id)sender {

    status.text = @"this is right btn";

}

- (IBAction)setStatusText:(id)sender {

    NSString *title = [sender titleForState:UIControlStateNormal];

//    status.text = title;

    NSString *newLableText = [NSString stringWithFormat:@"Hello, %@ btn", title];

    status.text = newLableText;

}

@end

ViewController.xib 文件

3. AZImageViewController

AZImageViewController.h 文件

#import "ViewController.h"

@interface AZImageViewController : ViewController

@property (retain, nonatomic) IBOutlet UITextField *nameField;

@property (retain, nonatomic) IBOutlet UITextField *numberField;

@property (retain, nonatomic) IBOutlet UILabel *rateLabel;

- (IBAction)textFieldDoneEditing:(id)sender;

- (IBAction)backgroudTap:(id)sender;

- (IBAction)sliderMove:(id)sender;

@end

AZImageViewController.m 文件

#import "AZImageViewController.h"

@interface AZImageViewController ()

@end

@implementation AZImageViewController

@synthesize nameField;

@synthesize numberField;

@synthesize rateLabel;

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil {

    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];

    if (self) {

        self.title = NSLocalizedString(@"Second", @"Second");

        self.tabBarItem.image = [UIImage imageNamed:@"second"];

    }

    return self;

}

#pragma mark - Custom Method

- (IBAction)textFieldDoneEditing:(id)sender {

    [sender resignFirstResponder];

}

- (IBAction)backgroudTap:(id)sender {

    [nameField resignFirstResponder];

    [numberField resignFirstResponder];

}

- (IBAction)sliderMove:(id)sender {

    UISlider *slider = (UISlider *)sender;

    NSInteger _rate = (NSInteger)roundf(slider.value);

    rateLabel.text = [NSString stringWithFormat:@"%ld", _rate];

}

- (void)dealloc {

    [nameField release];

    [numberField release];

    [rateLabel release];

    [super dealloc];

}

@end

AZImageViewController.xib 文件

4. info_plist
