This document provides information and code snippets for iOS app development using Objective-C and Xcode. It covers topics such as adding an app icon and splash screen, setting the orientation to portrait only, adding an action sheet with buttons, and implementing a delegate method to handle button clicks. The document also discusses deploying the app by adding the bundle ID to the developer website and installing an archive file on a device.

3. iOS App Development
 App Logo / App Icon
 App Splash Screen
 App Orientation

4. App icon

5. Splash Screen

6. Increase screen time
[NSThread sleepForTimeInterval:5.0];
Add above line in viewController.m:
- (void)viewDidLoad
{
[NSThread sleepForTimeInterval:5.0];
[super viewDidLoad];
}

7. Only Portrait

9. Action Sheet
 Drag a button on Interface Builder

10. Create IBAction
 Ctrl + Click + Drag

11. Create UIActionSheet Obj.
- (IBAction)openActionSheet:(id)sender {
UIActionSheet *asheet=[[UIActionSheet
alloc]initWithTitle:
@"MyActionSheet" delegate:self
cancelButtonTitle:@"Cancel"
destructiveButtonTitle:@"Save"otherButtonTitles:@"Ok",@
"myTitle", nil];
[asheet showInView:self.view];
}

12. Implement a delegate
method
- (void)actionSheet:(UIActionSheet *)actionSheet
clickedButtonAtIndex:(NSInteger)buttonIndex{
if(buttonIndex==0){
UIAlertView *alert0 = [[UIAlertView alloc]initWithTitle:@"Welcome"
message:@"you clicked 0" delegate:nil cancelButtonTitle:@"cancle"
otherButtonTitles:nil];
[alert0 show];
}else{
UIAlertView *alert1 = [[UIAlertView alloc]initWithTitle:@"Welcome"
message:@"you clicked 1" delegate:nil cancelButtonTitle:@"cancle"
otherButtonTitles:nil];
[alert1 show];
}
}

13. To make it work
@interface ViewController :
UIViewController<UIAlertViewDelegate>
Add <UIAlertViewDelegate> after classname

14. Output after clicking button
click me… other than save

15. Deployment of App
 Add app bundle id in to website.
 Create an archive (.ipa)
 Install archive on device
