Saving Image to file from imagePickerController - unable to load image - ios

Question

I'm not quite sure whats going wrong here, I'd really appreciate some help as I'm very stuck.
This is my imagePickerController
-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
[[NSUserDefaults standardUserDefaults] setObject:[NSNumber numberWithLong:customphoto1] forKey:#"customphoto1count"];
UIImage *button1Image = [info objectForKey:#"UIImagePickerControllerOriginalImage"];
pngData = UIImagePNGRepresentation(button1Image);
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsPath = [paths objectAtIndex:0]; //Get the docs directory
NSString *filePath = [documentsPath stringByAppendingPathComponent:#"Button1image.png"]; //Add the file name
[pngData writeToFile:filePath atomically:YES]; //Write the file
[self dismissViewControllerAnimated:YES completion:NULL];
pngData = [NSData dataWithContentsOfFile:filePath];
UIImage *imageLoaded = [UIImage imageWithData:pngData];
[_button1 setImage:imageLoaded forState:UIControlStateNormal];
self.button1.clipsToBounds = YES;
self.button1.layer.cornerRadius = (self.button1.frame.size.width / 16);//half of the width
self.button1.layer.borderColor=[UIColor blackColor].CGColor;
self.button1.layer.borderWidth=1.0f;
[self dismissViewControllerAnimated:YES completion:NULL];
}
The above saves the image (as far as I believe) since _button1 is reading from imageLoaded
When the app closes and is reopened, this is the what calls the button to be displayed, and should load the picture from my NSData:
-(void)customButton1{
if (customphoto1 == 1) {
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsPath = [paths objectAtIndex:0]; //Get the docs directory
NSString *filePath = [documentsPath stringByAppendingPathComponent:#"Button1image.png"]; //Add the file name
[pngData writeToFile:filePath atomically:YES];
pngData = [NSData dataWithContentsOfFile:filePath];
UIImage *imageLoaded1 = [UIImage imageWithData:pngData];
NSLog(#"%#", filePath);
// UIImage *imageload1 = [UIImage imageWithData:[newManagedObject valueForKey:#"imagesone"]];
[_button1 setImage:imageLoaded1 forState:UIControlStateNormal];
}
else {
button1ImageName = #"addnew";
}
}
Why is my image not loading?
Many thanks

Try this:
-(void)customButton1{
if (customphoto1 == 1) {
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsPath = [paths objectAtIndex:0]; //Get the docs directory
NSString *filePath = [documentsPath stringByAppendingPathComponent:#"Button1image.png"];
UIImage *imageLoaded1 = [UIImage imagewithcontentsoffile:filePath];
NSLog(#"%#", filePath);
[_button1 setImage:imageLoaded1 forState:UIControlStateNormal];
}
else {
button1ImageName = #"addnew";
}
}
Debug: Check whether the filepath which is getting printed is correct or not. Open this path in Finder > CMD + Shift + G and paste the path (remove the file name from the path, use till folder level). Then check if that particular image is available in that folder or not.
Also in your didFinishPickingMediaWithInfo method, you are calling dismissViewControllerAnimated method two times, it should be once and at the end of method.
Hope this helps

Image was saving and loading alright all along - issue turned out to be with the buttons setImage function
