.h

import <UIKit/UIKit.h>

import <Parse/Parse.h>

@interface ImageViewController : UIViewController

@property (nonatomic, strong) PFObject *message; @property (nonatomic, retain) IBOutlet UIImageView *imageView;

@end

.m

import "ImageViewController.h"

@interface ImageViewController ()

@end

@implementation ImageViewController

  • (void)viewDidLoad { [super viewDidLoad]; PFFile *imageFile = [self.message objectForKey:@"file"]; NSURL *imageFileUrl = [[NSURL alloc] initWithString:imageFile.url]; NSData *imageData = [NSData dataWithContentsOfURL:imageFileUrl]; self.imageView.image = [UIImage imageWithData:imageData];

    NSString *senderName = [self.message objectForKey:@"senderName"]; NSString *title = [NSString stringWithFormat:@"Sent from %@", senderName]; self.navigationItem.title = title; }

  • (void)viewDidAppear:(BOOL)animated { [super viewWillAppear:animated];

    if ([self respondsToSelector:@selector(timeout)]) { [NSTimer scheduledTimerWithTimeInterval:10 target:self selector:@selector (timeout)userInfo:nil repeats:NO]; } else { NSLog(@"Error:selector missing!"); } }
