I'm trying to take a photo using iPhone camera and save it to both document folder and Photo Album and load this image in another scene. Here is my code:
For image saving (in scene A):
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
UIImage *chosenImage = info[UIImagePickerControllerEditedImage];
self.ImageView.image = chosenImage;
[picker dismissViewControllerAnimated:YES completion:NULL];
NSString *mediaType = info[UIImagePickerControllerMediaType];
if ([mediaType isEqualToString:(NSString *)kUTTypeImage]) {
NSString *fileName = [NSString stringWithFormat:@"%@.png", self.patientMRN];
NSURL *urlSave = [[self getDocumentsPathURL] URLByAppendingPathComponent:fileName];
[UIImagePNGRepresentation(chosenImage) writeToFile:urlSave.path atomically:YES];
UIImageWriteToSavedPhotosAlbum(chosenImage, nil, nil, nil);
}
}
And for image loading (in scene B):
-(void)loadDefaultImage
{
NSString *fileName = [NSString stringWithFormat:@"%@.png", self.patientMRN];
NSURL *urlImage = [[self getDocumentsPathURL] URLByAppendingPathComponent:fileName];
if ([[NSFileManager defaultManager] fileExistsAtPath:urlImage.path]) {
NSData *dataFile = [[NSFileManager defaultManager] contentsAtPath:urlImage.path];
UIImage *image = [[UIImage alloc] initWithData:dataFile];
self.imageView.contentMode = UIViewContentModeScaleAspectFill;
self.imageView.autoresizingMask =
( UIViewAutoresizingFlexibleBottomMargin
| UIViewAutoresizingFlexibleHeight
| UIViewAutoresizingFlexibleLeftMargin
| UIViewAutoresizingFlexibleRightMargin
| UIViewAutoresizingFlexibleTopMargin
| UIViewAutoresizingFlexibleWidth );
self.imageView.image = image;
}
else {
NSLog(@"Image not found");
}
}
Now i have two problems.
In scene A, i have an UIImageView for which i set height and width constraints. Below the UIImageView i have two buttons, one for take photo and one for going back. After taking the photo and choose use photo, it'll go back to scene A and display the captured image in the UIImageView. However, the image displayed got so big it partially overlaps two buttons beneath it, as if the constraints i set doesn't work at all. Why does this happen?
In scene B, i have a smaller UIImageView used to display the photo i took earlier. However, only part of the original image is shown in scene B's imageView. I tried to set the contentMode as UIViewContentModeScaleAspectFill and set the autoresizingMask, but still doesn't work. Where does it go wrong?
Edit:
The Problem is solved! After i dragged the UIImageview to the storyboard, i just resize it to fit the screen, but forgot to add height and width constraints to it. Now i add the constraints, the image is displayed as expected. Thank you guys.
