Working on my second app...
Have buttons going to individual images and when app moves to new image. I want to play sound, but its not working...
in .h file:
#import <UIKit/UIKit.h>
#import <AVFoundation/AVFoundation.h>
#import "SoundController.h"
#interface BoatController : UIViewController {
}
#property (nonatomic, retain) UIView *Cruise_Ship;
#property (nonatomic, retain) UIView *Speed_Boat;
#end
in .m file:
#import "BoatController.h"
#implementation BoatController
#synthesize Cruise_Ship;
#synthesize Speed_Boat;
- (void)viewDidLoad {
[super viewDidLoad];
}
-(void)View01
{
UIView * containingView = Cruise_Ship;
[self.view removeFromSuperview];
[containingView addSubview:Cruise_Ship];
CFBundleRef mainBundle = CFBundleGetMainBundle();
CFURLRef soundFileURLRef;
soundFileURLRef = CFBundleCopyResourceURL(mainBundle, (CFStringRef) #"boathorn01",CFSTR ("wav"), NULL);
SystemSoundID soundID;
AudioServicesCreateSystemSoundID(soundFileURLRef, &soundID);
AudioServicesPlaySystemSound(soundID);
}
-(void)View2
{
UIView * containingView = Speed_Boat.superview;
[self.view removeFromSuperview];
[containingView addSubview:Speed_Boat];
CFBundleRef mainBundle = CFBundleGetMainBundle();
CFURLRef soundFileURLRef;
soundFileURLRef = CFBundleCopyResourceURL(mainBundle, (CFStringRef) #"nautical010",CFSTR ("wav"), NULL);
SystemSoundID soundID;
AudioServicesCreateSystemSoundID(soundFileURLRef, &soundID);
AudioServicesPlaySystemSound(soundID);
}
#end
Any ideas? Trying to move from a controller via buttons to various pictures. Navigation works, but sounds do not play.
You can use:
system("afplay path")

I've recently created a app with Xcode. When 2 images collide, it sends me to a new screen (which is good). However, when i push the button to return me back to the original view, it goes blank. Can you tell me why? Any feed back is appreciated.
Here is code from the First .h file:
import
#interface ViewController : UIViewController {
IBOutlet UIImageView *image1;
IBOutlet UIImageView *image2;
}
#property (nonatomic, retain) UIImageView *image1;
#property (nonatomic, retain) UIImageView *image2;
-(void)collision;
#end
And from the .m:
import "ViewController.h"
import "newview.h"
#interface ViewController ()
#end
#implementation ViewController
#synthesize image1, image2;
-(void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event {
UITouch *mytouch = [[event allTouches] anyObject];
image1.center = [mytouch locationInView:self.view];
[self collision];
}
-(void)collision {
if (CGRectIntersectsRect(image1.frame, image2.frame)) {
newview *second = [[newview alloc] initWithNibName:nil bundle:nil];
[self presentModalViewController:second animated:YES];
}
}
here is code from the second .h (The one with the go back button):
(IBAction)retry:(id)sender;
and from the .m:
import "newview.h"
import "ViewController.h"
#interface newview ()
#end
#implementation newview
(IBAction)retry:(id)sender {
ViewController *second = [[ViewController alloc] initWithNibName:nil bundle:nil];
[self presentModalViewController:second animated:YES];
}
The blank screen is another modal view from (IBAction)retry:(id)sender.
You should use [self dismissModalViewControllerAnimated:YES]; in (IBAction)retry:(id)sender for going back to previous screen instead of presenting another modal view.
Creating an app on Xcode 4.5.1 and wondering how do i save the current image in the specified UIImageView when i navigate to a different view. Then when i return to the View it loads up the saved image into the UIImageView?
Thank a lot, appreciate it :D
The code I've posted below involves passing a uiimage to a second view controller. It also includes a button on each controller to move back and forth between the two. The saved image will stay in the uiimageview when you switch to and from the views.
SecondView.h
#import <UIKit/UIKit.h>
#interface SecondView : UIViewController {
IBOutlet UIImageView *yourphotoview;
UIImage *yourimage;
}
#property (retain, nonatomic) UIImage *yourimage;
- (IBAction)back;
#end
SecondView.m
#import "ViewController.h"
#import "SecondView.h"
#interface SecondView ()
#end
#implementation SecondView
#synthesize yourimage;
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
// Custom initialization
}
return self;
}
- (void)viewDidLoad
{
yourphotoview.image = image;
[super viewDidLoad];
// Do any additional setup after loading the view.
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
- (IBAction)back {
[self dismissViewControllerAnimated:YES completion:NULL];
}
- (void)dealloc {
[image release];
[super dealloc];
}
#end
ViewController.h
#import <UIKit/UIKit.h>
#import "SecondView.h"
#interface ViewController : UIViewController
{
IBOutlet UISlider *compression;
IBOutlet UISwitch *smurferderp;
SecondView *SecondViewdata;
}
#property (retain, nonatomic) SecondView *SecondViewdata;
#property (retain, nonatomic) IBOutlet UIImageView *theimage;
- (IBAction)switchview:(id)sender;
#end
ViewController.m
#import "ViewController.h"
#import "SecondView.h"
#interface ViewController ()
#end
#implementation ViewController
#synthesize SecondViewdata, theimage;
- (IBAction)switchview:(id)sender {
SecondView *secondview = [self.storyboard instantiateViewControllerWithIdentifier:#"rr"];
self.SecondViewdata = secondview;
SecondViewdata.yourimage = theimage.image;
[self presentViewController: secondview animated:YES completion:NULL];
}
- (void)dealloc {
[theimage release];
[super dealloc];
}
#end
My objective is to show in a label the text of an object of a custom class called Files. Here is Files.h :
#import <Foundation/Foundation.h>
#interface Files : NSObject
#property (nonatomic, retain) NSString *title;
#property (nonatomic, retain) NSString *text;
#end
This is Files.m :
#import "Files.h"
#implementation Files
#dynamic title;
#dynamic text;
#end
Here is the .h file of my app. the label is called trackName:
#import <UIKit/UIKit.h>
#import "Files.h"
#interface FirstViewController : UIViewController
{
Files *plainpalais;
}
#property (weak, nonatomic) IBOutlet UILabel *trackName;
-(Files*) chooseFile;
#end
This is the .m file of the app:
#import "FirstViewController.h"
#interface FirstViewController ()
#end
#implementation FirstViewController
#synthesize trackName;
-(Files*)chooseFile
{
return plainpalais;
}
- (void)viewDidLoad
{
[super viewDidLoad];
plainpalais.text=#"hello";
plainpalais.title=#"plainpalais";
trackName.text=plainpalais.title;
// Do any additional setup after loading the view, typically from a nib.
}
- (void)viewDidUnload
{
[self setTrackName:nil];
[super viewDidUnload];
// Release any retained subviews of the main view.
}
- (BOOL)shouldAutorotateToInterfaceOrientation: (UIInterfaceOrientation)interfaceOrientation
{
if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone) {
return (interfaceOrientation != UIInterfaceOrientationPortraitUpsideDown);
} else {
return YES;
}
}
#end
The problem is that the label trackName doesn't show plainpalais...
Thanks for help !
PS: I'm a beginner so this is probably a basic mistake.
You have used #dynamic in your Files.m implementation which tells the compiler that you'll provide getters/setters for these properties at a later time, i.e. using the Objective-C runtime.
I suspect you want to use #synthesize rather than #dynamic. For example,
#import "Files.h"
#implementation Files
#synthesize title;
#synthesize text;
#end
Also you haven't actually created a Files object in the code you have given us. The chooseFile method appears to be returning a nil object (assuming you haven't initialised plainpalais somewhere else). Perhaps you should initialise plainpalais in an init method, e.g.
- (id)init {
self = [super init];
if (self) {
plainpalias = [[Files alloc] init];
}
return self;
}
Don't forget to release this object in dealloc (if you aren't using ARC).
I have an app with ads banner (inner-active) in every view controller (4 views) and i keep getting this error after 2-3-4 minutes that my app is running:
'NSRangeException', reason: '*** -[__NSCFString substringToIndex:]: Range or index out of bounds'
My app is crashing & i can't find the solution for that, but i know for sure that is something with my AD banner issue cau's when i comment the ad banner code everything works great. i can assume that it happens when new request is loading on the banner.
This is the code i'm using for the AD banner:
.h file:
#property (nonatomic, retain) UIView *adBanner;
.m file:
Did synthesize & import for what i need and after that:
- (void)viewWillAppear:(BOOL)animated
{
CGRect frame = CGRectMake(0, 430, 320, 50);
self.adBanner = [[UIView alloc] initWithFrame:frame];
[self.view addSubview:self.adBanner];
// Display ad
if (![InneractiveAd DisplayAd:#"iOS_Test" withType:IaAdType_Banner withRoot:adBanner withReload:60 withParams:optionalParams])
{
adBanner.hidden = YES;
}
}
This is my AppDelegate (don't know why but maybe it something with that too?):
.h file:
#import <UIKit/UIKit.h>
#class RootViewController;
#interface AppDelegate : UIResponder <UIApplicationDelegate>
#property (strong, nonatomic) UIWindow *window;
#property (nonatomic, strong) RootViewController *rootViewController;
#end
.m file:
#import "AppDelegate.h"
#import "RootViewController.h"
#implementation AppDelegate
#synthesize window = _window;
#synthesize rootViewController;
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
// Override point for customization after application launch.
self.rootViewController = [[RootViewController alloc] initWithNibName:nil bundle:NULL];
[self.window addSubview:self.rootViewController.view];
[self.window makeKeyAndVisible];
return YES;
}
I realy don't understand what it could be and how it related to NSCFString :\
Thanks.
Not sure if you got an answer to this but I was getting it with this line of code when there was no internet connection.
NSString *value = [serverOutput substringWithRange:NSMakeRange(2, [serverOutput length] - 2 * 2)];
I had to protect it with a check to the internet connection and an if then statement
I can't call the class "MapAnnotation" on XCode 4. I'm working on coding that will allow me to place pins in an MKMapView. I believe I've imported the right delegates. Here's what I've got:
MillersLocations.h
#import <Foundation/Foundation.h>
#import <MapKit/MKAnnotation.h>
#import <MapKit/MapKit.h>
#interface MillersLocations : NSObject <MKAnnotation> {
CLLocationCoordinate2D coordinate;
NSString *title;
NSString *subtitle;
}
#property (nonatomic, assign) CLLocationCoordinate2D coordinate;
#property (nonatomic, copy) NSString *title;
#property (nonatomic, copy) NSString *subtitle;
#end
MillersLocations.m
#import "MillersLocations.h"
#implementation MillersLocations
#synthesize coordinate, title, subtitle;
-(void)dealloc{
[title dealloc];
[subtitle dealloc];
[super dealloc];
}
#end
And here's my view controller for the map view:
MapViewController.h
#import <UIKit/UIKit.h>
#import <MapKit/MapKit.h>
#interface MapViewController : UIViewController <MKMapViewDelegate> {
IBOutlet MKMapView *mapView;
}
#end
MapViewController.m (just the segment I'm looking at)
#import "MapViewController.h"
#import "MillersLocations.h"
#implementation MapViewController
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
}
return self;
}
//skipping forward
- (void)viewDidLoad
{
[super viewDidLoad];
MKCoordinateRegion store1;
store1.center.latitude = 36.8605679;
store1.center.longitude = -76.2866713;
store1.span.latitudeDelta = 0.1;
store1.span.longitudeDelta = 0.1;
[mapView setRegion:store1 animated:YES];
//this is where I'm trying to put this code in:
MapAnnotation* annotation = [[MapAnnotation alloc] initWithCoordinate:newCoord];
//BUT "MapAnnotation" isn't an option
}
I'm wondering if I haven't imported the rights classes or something. I've Googled it and can't seem to find where "MapAnnotation" lies. What do I need to import to get access to "MapAnnotation"? Everything works fine up until that point.
Thanks for the help. I'm just learning this stuff!
What makes you think that there is class called MapAnnotation? Your annotation class is called MillersLocations. You need to create instances of that class and call [mapView addAnnotation:millersLocationInstance]; (or something similar).
