UI Activity View Errors - ios

Question

I'm quite the beginner to iOS Programming, and I googled how to get the UI Activity View implemented, but I'm getting errors that I do not quite understand. Anyone that can help me figure out what the errors mean in more specific detail and how to fix them, it would be greatly appreciated.
#pragma mark - SHARING OPTIONS (using a DocumentInteractionController) =============
/* =================
NOTE: The following methods work only on real device, not iOS Simulator, and you should have apps like Instagram, iPhoto, etc. already installed into your device!
================= */
-(void)shareImageToAllAppsAvailable {
NSLog(#"This code works only on device. Please test it on iPhone!");
// makes an NSURL file to the processed Image that needs to be saved
NSURL *fileURL;
docIntController.delegate = self;
//Saves the Image to default device directory
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *savedImagePath = [documentsDirectory stringByAppendingPathComponent:#"My Selfie.jpg"];
UIImage *image = combinedImage;
NSData *imageData = UIImagePNGRepresentation(image);
[imageData writeToFile:savedImagePath atomically:NO];
//Load the Image Path
NSString *getImagePath = [documentsDirectory stringByAppendingPathComponent:#"My Selfie.jpg"];
// this blank line here creates error 'use of undeclared identifier 'showActivityViewController''
// Create the URL path to the Image to be saved
fileURL = [[NSURL alloc] initFileURLWithPath:getImagePath];
// Open the Document Interaction controller for Sharing options
-(void)showActivityViewController
{
//-- set up the data objects
NSString *textObject = _aTextView.text;
UIImage *image = [UIImage imageNamed:#"My Selfie.jpg"];
NSArray *activityItems = [NSArray arrayWithObjects:textObject, url, image, nil];
//-- initialising the activity view controller
UIActivityViewController *avc = [[UIActivityViewController alloc]
initWithActivityItems:activityItems
applicationActivities:nil];
//-- define the activity view completion handler
avc.completionHandler = ^(NSString *activityType, BOOL completed){
NSLog(#"Activity Type selected: %#", activityType);
if (completed) {
NSLog(#"Selected activity was performed.");
} else {
if (activityType == NULL) {
NSLog(#"User dismissed the view controller without making a selection.");
} else {
NSLog(#"Activity was not performed.");
}
}
};
}

You're missing a closing } before your -(void)showActivityViewController declaration.
It looks like you're trying to call that method by defining it within another method, which is not valid Objective-C. Use the self construct to reference methods defined in the same class.
