Stack in SwiftUI

In previous post we have used Stack but i have not explained it there.
SwiftUI allows us to add nested Stacks too means you can have a HStack inside a VStack or vice-versa or any other combinations.

SwiftUI has categorized Stack into 3 types:
1. HStack - Horizontal Stack
2. VStack - Vertical Stack
3. ZStack - Z Index Stack

1. HStack - If you want to place UI horizontally use this type.

Code Snipped:
struct ContentView: View {
    var body: some View {
        HStack {
            Color(.red)
            Color(.blue)
        }
    }
}

Explanation - Here i have created a HStack and added two Color's namely red and blue.
Now you would like to ask me how you can add a Color instead of a View!!!
So in SwiftUI we can treat Color also as a View, let me elaborate it.
It will draw a View within a provided space by the HStack and fill it with the provided Color and returns it as a View.

Output of Code Snippet:




2. VStack - This will add a Vertical Stack to your View.

Code Snippet:
struct ContentView: View {
    var body: some View {
        VStack {
            Color(.red)
            Color(.blue)
        }
    }
}

Explanation - Similar to HStack here we have the VStack it will place the items in Vertical manner. Red color on top and blue color on bottom.


Output of Code Snippet:



























3. ZStack - If you want to place items one above another this is the one you can use.

Code Snippet:
struct ContentView: View {
    var body: some View {
        ZStack {
            Color(.red)
            Text("This is On the Top of Red Color View")
                .foregroundColor(.white)
        }
    }
}

Explanation -
Sometimes we need to place some item above other, like a Text on Image. So here we have a ZStack here to make it simple. I have placed a Text above the Color.

Output of Code Snippet:

Here is a code snippet for nested Stack:
struct ContentView: View {
    var body: some View {
        HStack {
            VStack {
                Color(.red)
                Color(.green)
            }
            Color(.blue)
        }
    }
}

Explanation - I have added a VStack inside HStack, so the left side will have two Color Views red and green.

UITableView - Add or Remove Rows Dynamically (Objective C & Swift Source codes)

In some situations we need to add or remove rows dynamically from a UITableView. We can achieve it very easily, just got through the tutorial : 1. Create a new project. 2.  In AppDelegate implementation file create an object of UINavigationController (navController here). 3. Add object of UIViewController (viewController here) as rootviewcontroller of UINavigationController. 4. In ViewController.xib nib file take a UITableView. 5. Set delegate and datasource of UITableView to File's Owner. 6. Create an IBOutlet to UITableView (tableViewForScreen here) in ViewControler.h header file. 7. Declare an object of NSMutableArray (arrayForTableContent here) in ViewControler.h header file. 8. In ViewController.m file in viewDidLoad method set edit and add buttons as leftBarButtonItem and rightBarButtonItem respectively. 9. Initialize arrayForTableContent array and add objects to it.
