Camera images are changing the orientation automatically in iphone - iphone

Question

Im developing a photo app.
Here i'm using the images from both photo library and also the images taking through camera and displaying it in a image view.
The images from photo library is coming in correct orientation but camera images are displaying in different orientation.
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0]; // Get documents folder
NSString *dataPath = [documentsDirectory stringByAppendingPathComponent:#"MyFolder"];
NSString *imagePath = [dataPath stringByAppendingPathComponent:#"girl.jpg"];
if ([[NSFileManager defaultManager] fileExistsAtPath:imagePath]) {
UIImage *image = [UIImage imageWithCGImage:[UIImage imageWithContentsOfFile:imagePath].CGImage scale:bieberImage.image.scale
orientation:NO];
// bieberImage.transform = CGAffineTransformMakeRotation(1.57079633);
CABasicAnimation *crossFade = [CABasicAnimation animationWithKeyPath:#"contents"];
crossFade.duration = 3.0;
crossFade.fromValue = (id)bieberImage.image.CGImage;
crossFade.toValue = (id)image.CGImage;
[self.bieberImage.layer addAnimation:crossFade forKey:#"animateContents"];
}
Can anyone tell me how can i correct this problem.
Thanks in advance.

Answer 1

Replace:
UIImage *image = [UIImage imageWithCGImage:[UIImage imageWithContentsOfFile:imagePath].CGImage scale:bieberImage.image.scale
orientation:NO];
With:
UIImage *image = [UIImage imageWithCGImage:[UIImage imageWithContentsOfFile:imagePath].CGImage scale:bieberImage.image.scale
orientation:UIImageOrientationRight];
Edit:
Or try this:
- (UIImage*) rotateImage:(UIImage* )src {
UIImageOrientation orientation = src.imageOrientation;
UIGraphicsBeginImageContext(src.size);
[src drawAtPoint:CGPointMake(0, 0)];
CGContextRef context = UIGraphicsGetCurrentContext();
if (orientation == UIImageOrientationRight) {
CGContextRotateCTM (context, [self radians:90]);
} else if (orientation == UIImageOrientationLeft) {
CGContextRotateCTM (context, [self radians:90]);
} else if (orientation == UIImageOrientationDown) {
// NOTHING
} else if (orientation == UIImageOrientationUp) {
CGContextRotateCTM (context, [self radians:0]);
}
return UIGraphicsGetImageFromCurrentImageContext();
}
- (CGFloat) radians:(int)degrees {
return (degrees/180)*(22/7);
}
