Explanation / Answer

Step 1: Create your xcode project named <last-name><first-name>hw2

Select Application (in iOS) and then select "Single View Application" , then click on "Next". Under Product name, enter your project name as “<last-name><first-name>hw2”

Step 2: Now Drag from Object Library- “Vertical Stack View Object”

Step 3: Seek for the element “UILabel” from Library pane and drag it to your view. This will be found in right hand side.

Step 4: Next, search for the other element “UITextField” from lower part of right hand side and drag it into your view.

Step 5: Now, search “UIButton” from lower part of right hand side and drag it into your view.

Step 6: For changing the text of UIButton and UILabel, we need a method called “viewDidLoad”.

Add the code as follows:

(void)viewDidLoad

{//Additional setups can be done after loading of view from nib

    [super viewDidLoad];

    

    self. <last-name><first-name>hw2.text = @"name";

     self. <last-name><first-name>hw2.text = @"city";

    [self.saveButton setTitle:@"Save" forState:UIControlStateNormal];

}

Step 7: Add a method named “btnSaveClicked” under “handleButtonClick”.
