Popover with picker views not showing correctly - ios

Question

This is the code I have for when I try to open a popover that has 2 pickerviews in it.
-(void) showPopover {
NSLog(#"Showing popover.");
BOOL right = NO;
BOOL detected = NO;
int translate = 0;
if([[UIDevice currentDevice] orientation] == UIDeviceOrientationPortrait) {
NSLog(#"Device is now in Portrait Mode");
translate += 600;
detected = YES;
}
else if ([[UIDevice currentDevice] orientation] == UIDeviceOrientationLandscapeLeft) {
NSLog(#"Device is now in LandscapeLeft Mode ");
detected = YES;
}
else if ([[UIDevice currentDevice] orientation] == UIDeviceOrientationLandscapeRight) {
NSLog(#"Device is now in LandscapeRight Mode");
right = YES;
detected = YES;
}
else if([[UIDevice currentDevice]orientation] == UIDeviceOrientationPortraitUpsideDown) {
NSLog(#"Device is now in PortraitUpsideDown Mode");
detected = YES;
}
if(detected == NO) {
translate = 0;
NSLog(#"FREAK ACCIDENT, MATRIX GLITCH");
//right = YES;
}
if(right) translate += 600;
NSLog(#"Translate is %i", translate);
UIView *windowView = [[UIApplication sharedApplication] keyWindow];
UIViewController* popoverContent = [[UIViewController alloc]
init];
UIView* popoverView = [[UIView alloc]
initWithFrame:CGRectMake(0, 0, 600, 350)];
popoverView.backgroundColor = [UIColor colorWithWhite:1.0 alpha:0.0];
[pickerView setFrame:CGRectMake(0, 0, 150, 216)];
[popoverView addSubview:pickerView];
[secondPickerView setFrame:CGRectMake(150, 0, 450, 216)];
[popoverView addSubview:secondPickerView];
popoverContent.view = popoverView;
UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[button setFrame:CGRectMake(200, 250, 200, 50)];
[button setTitle:#"Go!" forState:UIControlStateNormal];
[button addTarget:self action:#selector(buttonPressed) forControlEvents:UIControlEventTouchUpInside];
[popoverView addSubview:button];
popoverContent.contentSizeForViewInPopover =
CGSizeMake(600, 300);
popoverController = [[UIPopoverController alloc]
initWithContentViewController:popoverContent];
[popoverController presentPopoverFromRect:CGRectMake(70 + translate, 512, 1, 1)
inView:windowView
permittedArrowDirections:UIPopoverArrowDirectionDown
animated:YES];
}
And if my iPad is laying down, the "matrix glitch" error prints out and causes my popover to not function properly. It also sometimes happen if the device is in a portrait mode.
The top picture is what it looks like when my popover doesn't function properly, the bottom is it working correctly.

[[UIDevice currentDevice] orientation] gives you the physical orientation
of the device, and there are 7 possible values:
typedef enum {
UIDeviceOrientationUnknown,
UIDeviceOrientationPortrait,
UIDeviceOrientationPortraitUpsideDown,
UIDeviceOrientationLandscapeLeft,
UIDeviceOrientationLandscapeRight,
UIDeviceOrientationFaceUp,
UIDeviceOrientationFaceDown
} UIDeviceOrientation;
What you probably want is the current orientation of the interface, which you get
by calling the interfaceOrientation method of the current view controller.
It has the 4 possible values
typedef enum : NSInteger {
UIInterfaceOrientationPortrait = UIDeviceOrientationPortrait,
UIInterfaceOrientationPortraitUpsideDown = UIDeviceOrientationPortraitUpsideDown,
UIInterfaceOrientationLandscapeLeft = UIDeviceOrientationLandscapeRight,
UIInterfaceOrientationLandscapeRight = UIDeviceOrientationLandscapeLeft
} UIInterfaceOrientation;
