A navigation bar appears at the top of an app screen. To read more about ithttps://developer.apple.com/designhttps://developer.apple.com/documentationGetting height of Navigation bar becomes important if you’ve multiple view controllers having different UI and requirement. It becomes hectic if you’re not aware how to get the height of the same or modify as per need. Let’s see how we can get the height of Navigation bar.import UIKit class ViewController: UIViewController { override func viewDidLoad() { super.viewDidLoad() let navBarHeight = UIApplication.shared.statusBarFrame.size.height + (navigationController?.navigationBar.frame.height ?? 0.0) print(navBarHeight) } }
For this, you can use ORDER BY DESC LIMIT. Let us first create a table −mysql> create table DemoTable -> ( -> Id int NOT NULL AUTO_INCREMENT PRIMARY KEY, -> Name varchar(100) -> ); Query OK, 0 rows affected (0.59 sec)Insert some records in the table using insert command −mysql> insert into DemoTable(Name) values('John'); Query OK, 1 row affected (0.12 sec) mysql> insert into DemoTable(Name) values('Sam'); Query OK, 1 row affected (0.19 sec) mysql> insert into DemoTable(Name) values('Carol'); Query OK, 1 row affected (0.34 sec)Display all records from the table using select statement −mysql> ...

In the crypt-arithmetic problem, some letters are used to assign digits to it. Like ten different letters are holding digit values from 0 to 9 to perform arithmetic operations correctly. There are two words are given and another word is given as answer of addition for those two words. As an example we can say that two words ‘BASE’ and ‘BALL’, and the result is ‘GAMES’. Now if we try to add BASE and BALL by their symbolic digits, we will get the answer GAMES.NOTE − There must be ten letters maximum, otherwise it cannot be solved.InputThis algorithm will take ...

The HTML DOM Legend Object in HTML represents the element.SyntaxFollowing is the syntax −Creating a elementvar legendObject = document.createElement(“LEGEND”)PropertiesHere, “LegendObject” can have the following properties −PropertyDescriptionformIt returns a reference of enclosing form that contains the legend elementExampleLet us see an example for Legend form property − Live Demo Legend form form { width:70%; margin: 0 auto; text-align: center; } * { padding: 2px; margin:5px; } input[type="button"] { border-radius: 10px; } ...

In C we have seen different format specifiers. Here we will see another format specifier called %p. This is used to print the pointer type data. Let us see the example to get a better idea.Example#include main() { int x = 50; int *ptr = &x; printf("The address is: %p, the value is %d", ptr, *ptr); }OutputThe address is: 000000000022FE44, the value is 50
This example demonstrate about How to start an activity when user clicks a notification in AndroidStep 1 − Create a new project in Android Studio, go to File ⇒ New Project and fill all required details to create a new project.Step 2 − Add the following code to res/layout/activity_main.xml. Step 3 − Add the following code to src/MainActivity.javapackage app.tutorialspoint.com.notifyme ; import android.app.NotificationChannel ; import android.app.NotificationManager ; import android.app.PendingIntent ; import android.content.Context ; import android.content.Intent ; import android.support.v4.app.NotificationCompat ; import android.support.v7.app.AppCompatActivity ; import android.os.Bundle ; import android.view.View ; import android.widget.Button ; public class MainActivity extends AppCompatActivity { ...

Let us first create three components −JComponent one = new JLabel("Label One"); one.setBorder(BorderFactory.createLineBorder(Color.yellow)); JComponent two = new JLabel("Label Two"); two.setBorder(BorderFactory.createLineBorder(Color.orange)); JComponent three = new JLabel("Label Three"); three.setBorder(BorderFactory.createLineBorder(Color.blue));Now, we will split one and two components.JSplitPane split1 = new JSplitPane(JSplitPane.HORIZONTAL_SPLIT, one, two); split1.setDividerLocation(0.5); split1.setDividerSize(2);After that the above splitted pane would be splitted with component three making the process nested −JSplitPane split2 = new JSplitPane(JSplitPane.VERTICAL_SPLIT, split1, three ); split2.setDividerLocation(0.9); split2.setDividerSize(2);The following is an example to create nested JSplitPane −Examplepackage my; import java.awt.BorderLayout; import java.awt.Color; import javax.swing.BorderFactory; import javax.swing.JComponent; import javax.swing.JFrame; import javax.swing.JLabel; import javax.swing.JSplitPane; public class SwingDemo { public static void main(String[] ...

To split a numerical query result, you can use the CONCAT() function in MySQL. Let us first create a table −mysql> create table DemoTable ( StudentId int ); Query OK, 0 rows affected (0.68 sec)Now you can insert some records in the table using insert command −mysql> insert into DemoTable values(2222); Query OK, 1 row affected (0.18 sec) mysql> insert into DemoTable values(5555); Query OK, 1 row affected (0.13 sec) mysql> insert into DemoTable values(4567); Query OK, 1 row affected (0.13 sec) mysql> insert into DemoTable values(8905); Query OK, 1 row affected (0.15 sec)Display all records from ...

The target attribute of the element is used to set where the linked document will open. You can set the document to open in a new window, same frame, parent frame, etc.Following is the syntax −Here, _blank is used to open the linked document in new window or tab, _self opens the linked document in the same frame as it was clicked, _parent opens the document in the parent frame, _top opens the linked document in the entire body of the window, frame opens the linked document in a named frame.Let us now see an example to implement target attribute ...

You might have come across many application where the screen extends to complete screen i.e transparent Status Bar and transparent navigation bar.Here we will be seeing how to create an application where the you’ll be having transparent status and navigation bar.So let’s get startedStep 1 − Open Xcode → New Project → Single View Application → Let’s name it “TransparentViews”Step 2 − Embed the View Controller in Navigation Controller. Add Image View and shown and add image.Step 3 − Run the application without adding any piece of code for making status and navigation bar transparent.The screen looks like belowStep 4 ... Read More
