프로그래밍 방식으로 탐색 모음에 단추 추가

프로그래밍 방식으로 탐색 모음에 단추 추가

---

안녕하세요, 탐색 모음의 오른쪽에있는 버튼을 프로그래밍 방식으로 설정해야합니다. 그러면 버튼을 누르면 몇 가지 작업을 수행 할 수 있습니다. 프로그래밍 방식으로 탐색 모음을 만들었습니다.

navBar=[[UINavigationBar alloc]initWithFrame:CGRectMake(0,0,320,44) ];

마찬가지로이 탐색 모음의 오른쪽에 버튼을 추가해야합니다. 내가 사용한 것을 위해

1.  

    UIView* container = [[UIView alloc] init];

    // create a button and add it to the container
    UIButton* button = [[UIButton alloc] initWithFrame:CGRectMake(0, 0, 130, 44.01)];
    [container addSubview:button];
    [button release];

    // add another button
    button = [[UIButton alloc] initWithFrame:CGRectMake(160, 0, 50, 44.01)];
    [container addSubview:button];
    [button release];

    // now create a Bar button item
    UIBarButtonItem* item = [[UIBarButtonItem alloc] initWithCustomView:container];

    // set the nav bar's right button item
    self.navigationItem.rightBarButtonItem = item;
    [item release];

2.  

    UIImage *im;
    im=[UIImage imageNamed:@"back.png"];
    [button setImage:im forState:UIControlStateNormal];
    [im release];
    backButton = [[UIBarButtonItem alloc] initWithCustomView:button];       
    [backButton setImageInsets:UIEdgeInsetsMake(0, -10,5, 5)];
    [self.navigationItem setRightBarButtonItem:backButton];

삼.  

    UIBarButtonItem *refreshItem = [[UIBarButtonItem alloc] initWithTitle:@"button"               style:UIBarButtonItemStylePlain target:self action:@selector(refreshLogsAction:)];
    self.navigationItem.rightBarButtonItem = refreshItem;

    [refreshItem release];

이 모든 방법을 시도했지만 오른쪽에 버튼이 표시되지 않습니다.

내 UIViewController파생 클래스 내부에서 다음을 사용하고 있습니다 viewDidLoad.

UIBarButtonItem *flipButton = [[UIBarButtonItem alloc] 
                               initWithTitle:@"Flip"                                            
                               style:UIBarButtonItemStyleBordered 
                               target:self 
                               action:@selector(flipView:)];
self.navigationItem.rightBarButtonItem = flipButton;
[flipButton release];

이렇게하면 제목이 Flip 인 오른쪽에 메서드를 호출하는 버튼이 추가됩니다.

-(IBAction)flipView

이것은 # 3과 매우 흡사하지만 내 코드 내에서 작동합니다.

UIImage* image3 = [UIImage imageNamed:@"back_button.png"];
CGRect frameimg = CGRectMake(15,5, 25,25);

UIButton *someButton = [[UIButton alloc] initWithFrame:frameimg];
[someButton setBackgroundImage:image3 forState:UIControlStateNormal];
[someButton addTarget:self action:@selector(Back_btn:)
     forControlEvents:UIControlEventTouchUpInside];
[someButton setShowsTouchWhenHighlighted:YES];

UIBarButtonItem *mailbutton =[[UIBarButtonItem alloc] initWithCustomView:someButton];
self.navigationItem.leftBarButtonItem =mailbutton;
[someButton release];

///// 호출 된 이벤트

-(IBAction)Back_btn:(id)sender
{
    //Your code here
}

빠른:

var image3 = UIImage(named: "back_button.png")
var frameimg = CGRect(x: 15, y: 5, width: 25, height: 25)

var someButton = UIButton(frame: frameimg)
someButton.setBackgroundImage(image3, for: .normal)
someButton.addTarget(self, action: Selector("Back_btn:"), for: .touchUpInside)
someButton.showsTouchWhenHighlighted = true

var mailbutton = UIBarButtonItem(customView: someButton)
navigationItem?.leftBarButtonItem = mailbutton

func back_btn(_ sender: Any) {
    //Your code here
}

탐색 모음에 검색 버튼을 추가하려면 다음 코드를 사용하세요.

 UIBarButtonItem *searchButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemSearch target:self action:@selector(toggleSearch:)];
self.navigationController.navigationBar.topItem.rightBarButtonItem = searchButton;

다음 방법을 구현하십시오.

- (IBAction)toggleSearch:(id)sender
{
    // do something or handle Search Button Action.
}

신속하게 navbar에 추가 버튼을 추가하는 방법 :

self.navigationItem.rightBarButtonItem = UIBarButtonItem(barButtonSystemItem: .Add, target: self, action: "onAdd:")

onAdd :

func onAdd(sender: AnyObject) {
}

---

Swift version, add this in viewDidLoad:

var doneButton = UIBarButtonItem(title: "Done", style: UIBarButtonItemStyle.Plain, target: self, action: "doneButton:")
navigationItem.rightBarButtonItem = doneButton

And this in your View Controller class

func doneButton(sender: UIBarButtonItem) {
    println(111)
}

---

self.navigationItem.rightBarButtonItem=[[[UIBarButtonItem alloc]initWithTitle:@"Save" style:UIBarButtonItemStylePlain target:self action:@selector(saveAction:)]autorelease];

-(void)saveAction:(UIBarButtonItem *)sender{

//perform your action

}

---

Use following code:

UIBarButtonItem *customBtn=[[UIBarButtonItem alloc] initWithTitle:@"Custom" style:UIBarButtonItemStylePlain target:self action:@selector(customBtnPressed)];
[self.navigationItem setRightBarButtonItem:customBtn];

---

Simple use native editBarButton like this

self.navigationItem.rightBarButtonItem = self.editButtonItem;
[self.navigationItem.rightBarButtonItem setAction:@selector(editBarBtnPressed)];

and then

- (void)editBarBtnPressed {
    if ([infoTable isEditing]) {
        [self.editButtonItem setTitle:@"Edit"];
        [infoTable setEditing:NO animated:YES];
    }
    else {
        [self.editButtonItem setTitle:@"Done"];
        [infoTable setEditing:YES animated:YES];
    }
}

Have fun...!!!

In ViewDidLoad method of ViewController.m

UIBarButtonItem *cancel = [[UIBarButtonItem alloc] initWithTitle:@"Cancel" style:UIBarButtonItemStyleBordered target:self action:@selector(back)];

[self.navigationItem setLeftBarButtonItem:cancel];

"(back)" selector is a method to dissmiss the current ViewController

Try this.It work for me. Add button to navigation bar programmatically, Also we set image to navigation bar button,

Below is Code:-

  UIBarButtonItem *Savebtn=[[UIBarButtonItem alloc]initWithImage:
  [[UIImage imageNamed:@"bt_save.png"]imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal] 
  style:UIBarButtonItemStylePlain target:self action:@selector(SaveButtonClicked)];
  self.navigationItem.rightBarButtonItem=Savebtn;

  -(void)SaveButtonClicked
  {
    // Add save button code.
  }

---

If you are not looking for a BarButtonItem but simple button on navigationBar then below code works:

UIButton *aButton = [UIButton buttonWithType:UIButtonTypeCustom];
[aButton setBackgroundImage:[UIImage imageNamed:@"NavBar.png"] forState:UIControlStateNormal];
[aButton addTarget:self
            action:@selector(showButtonView:)
  forControlEvents:UIControlEventTouchUpInside];
aButton.frame = CGRectMake(260.0, 10.0, 30.0, 30.0);
[self.navigationController.navigationBar addSubview:aButton];

Hello everyone !! I created the solution to the issue at hand where Two UIInterface orientations are wanted using the UIIMagePicker.. In my ViewController where I handle the segue to the UIImagePickerController

**I use a..

-(void) editButtonPressed:(id)sender {
   BOOL editPressed = YES;
    NSUserDefaults *boolDefaults = [NSUserDefaults standardUserDefaults];
    [boolDefaults setBool:editPressed forKey:@"boolKey"];
    [boolDefaults synchronize];

    [self performSegueWithIdentifier:@"photoSegue" sender:nil]; 

}

**

Then in the AppDelegate Class I do the following.

- (NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window {

    BOOL appDelBool;
    NSUserDefaults *boolDefaults = [NSUserDefaults standardUserDefaults];
    appDelBool = [boolDefaults boolForKey:@"boolKey"];

       if (appDelBool == YES)
           return (UIInterfaceOrientationMaskPortrait);
        else
            return UIInterfaceOrientationMaskLandscapeLeft;
}
