*************************************************************************

3. 피커뷰

*************************************************************************

1) 아웃렛을 선언하고 데이터를 받을 어레이를 만든다.

IBOutlet UIPickerView *picker;

NSMutableArray *pickData;

// Implement viewDidLoad to do additional setup after loading the view, typically from a nib.

- (void)viewDidLoad {

     pickData = [[NSMutableArray alloc]init];

     [pickData addObject:@"1빠"];

     [pickData addObject:@"2빠"];

     [pickData addObject:@"3빠"];

     [pickData addObject:@"4빠"];

     [pickData addObject:@"5빠"];

     [pickData addObject:@"6빠"];

     [super viewDidLoad];

}

2) 데이터 소스와 델리게이트 생성

// data source

// Picker View 개수

- (NSInteger)numberOfComponentsInPickerView:(UIPickerView *)pickerView

{

     return 1;

}

// Picker View의 데이터 개수

- (NSInteger)pickerView:(UIPickerView *)pickerView numberOfRowsInComponent:(NSInteger)component

{

     return [pickData count];

}

// delegate

- (NSString *)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component

{

     // NSLog(@"value : %i", row);

     return [pickData objectAtIndex:row];

}

- (void)pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component

{

     // 선택되었을시의 처리

     //label.text = [pickDataobjectAtIndex:row];

}

*************************************************************************

4. 뷰전환

*************************************************************************

뷰콘트롤러 하나에 뷰가 여러개 있을 때

- 최상위 뷰를 제거하고 새 뷰를 넣는다.

- (IBAction)ChangeView

{

     NSArray *subs = [windows subviews];

     [[subs objectAtIndex:0] removeFromSuperview];

     if([[subs objectAtIndex:0] == secondView)

     {

          [window addSubview:firstView];

     }

}

뷰콘트롤러 자체가 여러개 있을 때

- 루트뷰 콘트롤러 자체를 변경한다.

rootView *rView = [[rootView alloc]initWithNibName:@"rootView" bundle:nil];

self.view.window.rootViewController = rView;

[rView release];

내비게이션 콘트롤러에서의 뷰전환

1) push(front)

- 내비게이션 콘트롤러의 뷰콘트롤러를 설정한다.

UINavigationController *curNav = self.navigationController;

NewAccountView *viewControl = [[NewAccountView alloc]initWithNibName:@"NewAccountView" bundle:nil];

[curNav pushViewController:viewControl animated:YES];

[viewControl release];

2) pop(back) - 화면전환이 없을시에만 가능하다. 화면전환이 있다면..

UINavigationController *curNav = self.navigationController;

[curNavpopViewControllerAnimated:YES];

모달뷰인경우 

1) push

UINavigationController *curNav = self.navigationController;

[curNav presentModalViewController:thePlayer animated:NO]; 

2) pop

[self.navigationControllerdismissModalViewControllerAnimated:NO];

*************************************************************************

5. xib파일간의 데이터 전달

*************************************************************************

1) 전달받을 데이터 (SecondView)

@interface SecondView : UIViewController {

     NSString *receiveData; // FirstView 에서 넘어올 데이터

}

@property (readwrite, assign) NSString *receiveData;

@synthesize receiveData;

2) 전달받는 곳 (SecondView)

- (void)viewDidLoad {

lbltext.text = receiveData;

    [superviewDidLoad];

}

3) 전달하는 곳(FirstView)

// NavigationController인 경우

UINavigationController *sNav = self.navigationController;

SecondView *sView = [[SecondView alloc]initWithNibName:@"SecondView" bundle:nil];

sView.receiveData = textData.text;

[sNav pushViewController:sView animated:YES];

[sView release];

// View인 경우

rootView *rView = [[rootViewalloc]initWithNibName:@"rootView"bundle:nil];

self.view.window.rootViewController = rView;

[rView release];

*************************************************************************

6. Alert

*************************************************************************

1) UIAlertViewDelegate

- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex

{

     NSLog(@"Clicked Button index : %i", buttonIndex);

}

-(IBAction)clickSimple

{

     UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"제목" message:@"내용을적으면됨" delegate:self cancelButtonTitle:nil otherButtonTitles:@"OK버튼", nil];

     [alert show];

     [alert release];

}

-(IBAction)clickMulti

{

     UIAlertView *malert = [[UIAlertView alloc]initWithTitle:@"멀티제목" message:@"내용을적으셈" delegate:self cancelButtonTitle:nil otherButtonTitles:@"OK버튼", @"Cancel", nil];

     [malert show];

     [malert release];

}

2) UIActionSheetDelegate

// action sheet

- (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex

{

     NSLog(@"Action Sheet Index : %i\n", buttonIndex);

}

- (IBAction)clickActionSheet

{

     UIActionSheet *actionSheet = [[UIActionSheet alloc]initWithTitle:@"제목"delegate:self cancelButtonTitle:@"취소" destructiveButtonTitle:@"포커스" otherButtonTitles:@"천재", @"위대함", nil];

     [actionSheet showInView:[self view]];

     [actionSheet release];

}

*************************************************************************

7. ETC 콘트롤 : segmented, switch, slider, progress

*************************************************************************

1) secgmented control - |a|b|c|

인스펙터의 속성 : bar는 얇다, 매 세그먼트의 이름을 정해준다.

단순 IBAction과 동일하다. 단 sender를 사용한다.

- (IBAction) segmentChange:(id)sender

{

     NSLog(@"click Index: %i", [sender selectedSegmentIndex]);

}

2) switch control - [on|off]

- (IBAction) switchChange:(id)sender

{

     UISwitch *tmpSwitch = (UISwitch*)sender;

     if(tmpSwitch.isOn)

     {

          NSLog(@"On");

     }

     else 

     {

          NSLog(@"Off");

     }

}

3) slider control

- (IBAction) sliderChange:(id)sender

{

     UISlider *tmpSlider = (UISlider *)sender;

     NSLog(@"value : %f", tmpSlider.value);//0.0~1.0까지입니다.

}

4) progress view control : 아웃렛이 존재

IBOutlet UIProgressView *nowProgress;

단순하게 progress 접근자에 값만 세팅하면 변한다.

- (IBAction) click3

{

     nowProgress.progress = 1.0;

}

*************************************************************************

8. UITextField에서 키보드 감추기

*************************************************************************

- (IBAction)hiddenKeyboard

{

     NSLog(@"hidden keyboard");

     NSArray *subs = self.view.subviews;

     id curView;

     for(curView in subs)

     {

          if([curView conformsToProtocol:@protocol(UITextInputTraits)])

          {

               [curView resignFirstResponder];

          }

     }

}

*************************************************************************

10. 달력

*************************************************************************

// 현재 달력을 얻는다.

NSCalendar *calendar = [NSCalendar currentCalendar]; // 오늘달력을 얻는다.

unsigned unitFlags = NSYearCalendarUnit | NSMonthCalendarUnit |  NSDayCalendarUnit;

NSDate *date = [NSDate date]; // 오늘 날짜를 얻는다.

NSDateComponents *comp = [calendar components:unitFlags fromDate:date];

NSLog(@"yeay:month:day = %d:%d:%d", [comp year], [comp month], [comp day]);

NSDateComponents *comps = [[NSDateComponentsalloc] init];

[comps setMonth:20];

[comps setYear:1000];

NSDate *newDate = [calendar dateByAddingComponents:comps toDate:date options:0];

comp = [calendar components:unitFlags fromDate:newDate];

NSLog(@"yeay:month:day = %d:%d:%d", [comp year], [comp month], [comp day]);

[comps release];
