Stuck on Capturing Photo and Video Using UIImage Picker Controller task 1 and 2

I am not event sure where to begin on this question, Could someone point me in the right direction. I have been fine up to these last videos.

In this Latergram app, we only want to upload an image if the 'image' and 'caption' properties of the view controller below are set. In the 'upload' method, add a check to make sure that both properties have values before executing the block of code. Note: 'image' is a UIImage and 'caption' is an NSString.

LatergramViewController.m
#import "LatergramViewController.h"

@implementation LatergramViewController

- (IBAction)upload {

- (IBAction)upload { if (self.image !=nil && [self.caption length] !=0){
    CGSize newSize = CGSizeMake(320.0f, 480.0f);
    CGRect newRectangle = CGRectMake(0, 0, 320.0f, 480.0f);
    UIGraphicsBeginImageContext(newSize);

    }

    // Task 2: Line missing here! How do we draw the image in the resized context?

    UIImage *resizedImage = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();

    // Rest of code omitted for brevity!
}

@end
LatergramViewController.h
#import "UIViewController.h"
#import "UIImage.h"

@interface LatergramViewController : UIViewController

@property (nonatomic, strong) UIImage *image;
@property (nonatomic, assign) NSString *caption;

- (IBAction)upload;

@end
