I'm building an app using the UIImagePickerController and a custom Overlay. What is does is comparing two images (before image and after image). I am using a custom overlay with the before image when taking the after photo(please see the image attached).
iPhone 5 - ios7
iPhone 4 - iOS7 (When taking the image)
iPhone 4 - iOS 7 (After taking the photo)
See the size difference between iPhone 4 and iPhone 5 camera view.
Application works fine with iPhone 5 screen size(Both ios 6 and ios7). But iPhone 4/4s screen size, it works fine ONLY with iOS6. The issue is with iphone 4/4s(ios7 ONLY), Camera view takes full screen. That means, you can notice iPhone 5 camera view size ~ 320*427 (iOS 6 and iOS 7) iPhone 4 camera view size ~ 320*427 (iOS 6) BUT iPhone 4 camera view size ~ 320*480 (iOS 7).
After the image is taken, it fitted to the actual size of 320*427. Because of this issue, I cannot align before image with camera view on iPhone 4 iOS7 (because its screeches to 320*480).
Does anyone faces this strange issue. I tried almost everything, but NO luck. Any ideas please???
This is my piece code for loading the camera view with custom before photo overlay.
- (void)loadCameraWithImage
{
if (!isLoadedOnce)
{
isLoadedOnce = YES;
UIImagePickerController *cameraView = [[UIImagePickerController alloc] init];
cameraView.sourceType = UIImagePickerControllerSourceTypeCamera;
cameraView.wantsFullScreenLayout = NO;
if ([self respondsToSelector:@selector(setEdgesForExtendedLayout:)]) {
[self setEdgesForExtendedLayout:UIRectEdgeNone];
}
// crop before image
UIImage *imgTmpCropped = [self imageByCropping:imgBefore toRect:CGRectMake(0, 0, imgBefore.size.width/2, imgBefore.size.height)];
UIImage *overleyImage = [[UIImage alloc] initWithCGImage: imgTmpCropped.CGImage
scale: [UIScreen mainScreen].scale
orientation: UIImageOrientationDownMirrored];
UIImageView *crosshairView;
UIImageView *beforeView;
CGFloat screenHieght = [UIScreen mainScreen].bounds.size.height;
if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad){
//overleyImage = [UIImage imageNamed:@"overlay_ipad.png"];
crosshairView = [[UIImageView alloc] initWithImage:overleyImage];
crosshairView.frame = CGRectMake(0, 0, 768, 1024);
[crosshairView setUserInteractionEnabled:YES];
crosshairView.backgroundColor = [UIColor clearColor];
beforeView = [[UIImageView alloc] initWithImage:overleyImage];
beforeView.frame = CGRectMake(0, 0, 384, 1024);
beforeView.alpha = 0.5;
beforeView.contentMode = UIViewContentModeScaleAspectFill;
}
else {
//overleyImage = [UIImage imageNamed:@"overleyImageAfter.png"];
crosshairView = [[UIImageView alloc] init];
beforeView = [[UIImageView alloc] initWithImage:overleyImage];
if(screenHieght>500){
crosshairView.frame = CGRectMake(0, 60, 320, 480);
beforeView.frame = CGRectMake(0, 70, 160, 427);
}
else{
if([[[UIDevice currentDevice] systemVersion] floatValue] <7.0){
crosshairView.frame = CGRectMake(0, 0, 320, 480);
beforeView.frame = CGRectMake(0, 0, 160, 427);
}
else{
crosshairView.frame = CGRectMake(0, 0, 320, 480);
beforeView.frame = CGRectMake(0, 0, 160, 480);
}
}
[crosshairView setUserInteractionEnabled:YES];
crosshairView.backgroundColor = [UIColor clearColor];
beforeView.alpha = 0.5;
beforeView.contentMode = UIViewContentModeScaleToFill;
}
//[crosshairView addSubview:beforeView];
//set our custom overlay view
cameraView.cameraOverlayView = beforeView;

cameraView.showsCameraControls = YES;
cameraView.navigationBarHidden = YES;

}
