How to create a custom UIImagePickerController with full-screen images ios - ios

Question

I have a simple UIImagePickerController which will use the camera to take a picture, but there are a couple things I would like it to do:
Have a custom camera UI
Take a full-screen instead of 480x640 (if on 4inch phone)
Here is my code for showing the UIImagePickerController:
- (IBAction)pick:(id)sender {
NSLog(#"abc");
picker = [[UIImagePickerController alloc] init];
if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]) {
[picker setSourceType:UIImagePickerControllerSourceTypeCamera];
} else {
[picker setSourceType:UIImagePickerControllerSourceTypePhotoLibrary];
}
[picker setDelegate:self];
[self presentViewController:picker animated:YES completion:nil];
}
and here is for when the image gets taken:
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
[self dismissViewControllerAnimated:YES completion:nil];
UIImage *image = [info objectForKey:UIImagePickerControllerOriginalImage];
[imageView setImage:image];
}
How do I do this?
Thanks

For the first bullet point I suppose that you could use the cameraOverlayView property of an UIImagePickerController object to add your custom UI over the picker default interface:
- (IBAction)pick:(id)sender {
NSLog(#"abc");
picker = [[UIImagePickerController alloc] init];
if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]) {
[picker setSourceType:UIImagePickerControllerSourceTypeCamera];
} else {
[picker setSourceType:UIImagePickerControllerSourceTypePhotoLibrary];
}
// Add here your custom UI here
[picker setCameraOverlayView:self.customCameraOverlayView];
[picker setDelegate:self];
[self presentViewController:picker animated:YES completion:nil];
}
EDIT
I've tested the UIImagePickerController and it returns the image with it's full dimensions (PixelXDimension and PixelYDimension):
UIImagePickerControllerMediaMetadata = {
DPIHeight = 72;
DPIWidth = 72;
Orientation = 6;
"{Exif}" = {
ApertureValue = "2.526068811667588";
BrightnessValue = "-0.5779073354035674";
ColorSpace = 1;
DateTimeDigitized = "2013:04:07 22:30:03";
DateTimeOriginal = "2013:04:07 22:30:03";
ExposureMode = 0;
ExposureProgram = 2;
ExposureTime = "0.05882352941176471";
FNumber = "2.4";
Flash = 24;
FocalLenIn35mmFilm = 35;
FocalLength = "4.28";
ISOSpeedRatings = (
800
);
MeteringMode = 3;
PixelXDimension = 3264;
PixelYDimension = 2448;
SceneType = 1;
SensingMethod = 2;
ShutterSpeedValue = "4.058893689053568";
SubjectArea = (
1874,
1478,
610,
612
);
WhiteBalance = 0;
};
"{TIFF}" = {
DateTime = "2013:04:07 22:30:03";
Make = Apple;
Model = "iPhone 4S";
Software = "6.1.3";
XResolution = 72;
YResolution = 72;
};
};
EDIT
Also you could set to your image view the content mode to resize and fit the container view:
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
[self dismissViewControllerAnimated:YES completion:nil];
UIImage *image = [info objectForKey:UIImagePickerControllerOriginalImage];
[imageView setContentMode:UIViewContentModeScaleAspectFill];
[imageView setImage:image];
}
and after that to fit the imageView as you need in you view controller taking in consideration the device screen (4inch or not) using auto layout or auto sizing.
