UIActionSheet Menu in Xcode

To Show a Menu Sheet like below

We have to code as below

1. First of all, we need to add <UIActionSheetDelegate> delegate in class .h file

2. Now we have to code like below

UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle:@"Select Image from..." delegate:self cancelButtonTitle:@"Cancel" destructiveButtonTitle:nil otherButtonTitles:@"Camera", @"Image Gallary", nil];

actionSheet.actionSheetStyle = UIActionSheetStyleBlackTranslucent;

actionSheet.alpha=0.90;

actionSheet.tag = 1;

UIWindow* window = [[UIApplication sharedApplication] keyWindow];

if ([window.subviews containsObject:self.view]) {

    [actionSheet showInView:self.view];

} else {

    [actionSheet showInView:window];

}

Check iPhone or iPad by Code in Xcode

To Check iPhone or iPad view by Code, we can check by following code

if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone) {

    // Code for iPhone View

} else {

    // Code for iPad View

}

Now to Check iPhone5 or iPhone4, we can do a check in iPhone vide code

-(Boolean)checkIphone5{

    UIScreen *screen = [UIScreen mainScreen];

    CGRect fullScreenRect = screen.bounds;

    if (fullScreenRect.size.height==568) {

        return TRUE;

    }

    else{

        return FALSE;

    }

}

and We can use this as like below

if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone)

{

   if ([self checkIphone5]) {

      // Code for iPhone5 View

   }
   else
   {

      // Code for iPhone 4 View

   }

} else {

    // Code for iPad View

}

get Orientation of iPhone/iPad at runtime

Define previousOrientation first, as below in your class.h file

UIDeviceOrientation previousOrientation;

then write code in class.m as below to check the orientation of device. Remember Its not for accelerometer. 

- (id)init {

    

    if ((self=[super init])) {

        [[NSNotificationCenter defaultCenter] addObserver:self

                                                 selector:@selector(orientationChanged: )

                                                    name:@"UIDeviceOrientationDidChangeNotification" object:nil];

    }

}

- (void) orientationChanged:(NSNotification *)notification{

    UIDeviceOrientation orientation = [[UIDevice currentDevice] orientation];

    

    previousOrientation = orientation;

    if (previousOrientation == UIDeviceOrientationPortrait)

    {
        NSLog(@"PORTRAIT");
    }

    else if (previousOrientation == UIDeviceOrientationLandscapeLeft)

    {
        NSLog(@"LANDSCAPE LEFT");
    }

    else if (previousOrientation == UIDeviceOrientationLandscapeRight)

    {
        NSLog(@"LANDSCAPE RIGHT");
    }
    else
    {
        NSLog(@"PORTRAIT DOWN");
    }
}
