I am sorry for the long post but I am at my wits end and have been stumped for days over this. Here's the scenario. My app loads a response from core data, converts the values to NSStrings so that I can add them to an NSDictionary. Then the NSDictionary is converted to NSData so I can attach it as a file to email. The purpose of this is so I can create a database of information including images, videos, etc. I was able to get everything to work except I am having an issue with an NSMutableArray. Here's the process:
I create an event and then load the data for exporting with this code.
EventDB *per = [[EventDB alloc]init];
per.customLayoutArray = [record.customLayoutArray description] ?
[record.customLayoutArray description] : #"";
NSDictionary *dict = [per dictionaryWithValuesForKeys:#[#"customLayoutArray"];
NSData *data = [NSJSONSerialization dataWithJSONObject:dict options:0 error:NULL];
Then I email the data using MFMailComposer. Then I have a custom UTI that allows me the open the url from the email and then I import the data and load it into my coredata entity with this
if([[url pathExtension] isEqualToString:#"ipix"]) {
NSData *data = [NSData dataWithContentsOfURL:url];
NSError *error;
NSDictionary *jsonData = [NSJSONSerialization JSONObjectWithData:data
options:kNilOptions
error:&error];
NSEntityDescription *entity = [NSEntityDescription entityForName:#"TSPItem"
inManagedObjectContext:self.managedObjectContext];
TSPItem *record = (TSPItem *)[[NSManagedObject alloc] initWithEntity:entity
insertIntoManagedObjectContext:self.managedObjectContext];
if (record) {
NSString *datetime = [jsonData objectForKey:#"customLayoutArray"];
record.customLayoutArray = [[datetime propertyList] mutableCopy];
}
That works fine. It does import the way I want but when I launch the event I get this crash message
** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason:
'-[__NSCFString apply]: unrecognized selector sent to instance 0x1c81a5f60
Now here's the code where it crashes.
NSMutableArray *archiveArray = self.record.customLayoutArray;
NSString *mycustom = [NSString stringWithFormat:#"%#_customlayout",
self.record.eventname];
NSData *data = [NSKeyedArchiver archivedDataWithRootObject:archiveArray];
[[NSUserDefaults standardUserDefaults] setObject:data forKey:mycustom];
self.customLayoutArray = [NSKeyedUnarchiver unarchiveObjectWithData:data];
NSLog(#"BOOTH EVENT ID %#", self.customLayoutArray);
[self.customLayoutArray makeObjectsPerformSelector:#selector(apply)];
This is the log from BOOTH EVENT ID
BOOTH EVENT ID (
"<Rectangle:0x102d38cb0self.scaleValue=1.842393\n, self.rotateValue=0.000000\n, self.width=368.478516\n, self.height=368.478516\n, self.radius=0\n, self.frame={{104, 113.5}, {200, 200}}\n, self.isApplied=NO\n>",
"<Rectangle:0x102d393c0self.scaleValue=1.000000\n, self.rotateValue=0.000000\n, self.width=200.000000\n, self.height=200.000000\n, self.radius=0\n, self.frame={{253, 273.5}, {200, 200}}\n, self.isApplied=NO\n>"
)
The app crashes here. Now if I load the original event on my iPad (the one that I didn't export) the app works perfect and the NSLog response for BOOTH EVENT ID is identical.
The "apply" section refers to this file.

Sorry, I have read a bunch of tutorials how to create a custom Callout for MapKit Annotation. It works with NSLog, but I cannot display the information in the Callouts.
I have two type of icons on the map. This is my viewForAnnotation method:
-(MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id<MKAnnotation>)annotation {
if (! [annotation isKindOfClass:[IGAMapAnnotation class]]) {
return nil;
}
IGAMapAnnotation *myLocation = (IGAMapAnnotation *) annotation;
self.typeIsFix = [myLocation.navaidType isEqualToString:#"FIX"];
self.typeIsPort = [myLocation.navaidType isEqualToString:#"PORT"];
int planeImageViewTag = 42;
NSString *reuseId;
if (self.typeIsPort)
reuseId = #"IGAMapAnnotationPort";
else if (self.typeIsFix)
reuseId = #"IGAMapAnnotationFix";
else
reuseId = #"IGAMapAnnotationOther";
MKAnnotationView *annotationView = [mapView dequeueReusableAnnotationViewWithIdentifier:reuseId];
if (annotationView == nil)
{
annotationView = [[MKAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:reuseId];
annotationView.enabled = YES;
UIButton *annotationInfo = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
annotationView.rightCalloutAccessoryView = annotationInfo;
annotationView.canShowCallout = YES;
if (self.typeIsPort)
{
annotationView.image = [UIImage imageNamed:#"mapPORT.png"];
annotationView.centerOffset = CGPointMake(0, 0);
}
else if (self.typeIsFix)
{
annotationView.image = [UIImage imageNamed:#"mapFIX.png"];
annotationView.centerOffset = CGPointMake(0, 0);
}
else
return nil;
}
else
{
annotationView.annotation = annotation;
}
return annotationView;
}
Then I have a calloutAccessoryControlTapped method
- (void)mapView:(MKMapView *)mapview annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control
{
IGAAnnotationInfoViewController *popOverCallout = [[IGAAnnotationInfoViewController alloc]init];
UIPopoverController *popOver = [[UIPopoverController alloc] initWithContentViewController:popOverCallout];
popOver.popoverContentSize = CGSizeMake(300, 200);
[popOver presentPopoverFromRect:view.bounds
inView:view
permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
}
I have also created a UIViewController which I assigned to UIPopoverController.
Now, when I tap the button on my annotation I see a white space for text. Great. If I assign text to a label in UIViewController, it also works great (the following is my UIViewController.m):
- (void)viewDidLoad {
[super viewDidLoad];
txtCallout = [[UILabel alloc] initWithFrame:CGRectMake(0.0, 0.0, 300, 200) ];
txtCallout.font = [UIFont fontWithName:#"Arial Rounded MT Bold" size:(14.0)];
txtCallout.numberOfLines = 0;
txtCallout.clipsToBounds = YES;
txtCallout.backgroundColor = [UIColor clearColor];
txtCallout.textColor = [UIColor blackColor];
txtCallout.textAlignment = NSTextAlignmentLeft;
txtCallout.text = #"text\ntext\ntext";
[self.view addSubview:txtCallout];
}
But how do I insert the text from my annotation method? Also the text must be different depending on the icon type, say #"PORT, PORT" or #"FIX,FIX". How do I do it?
EDIT:
I have managed to display callouts with the necessary information passed. My last problem is that sometimes my callout is 3 lines, sometimes -- as many as 15. How is it possible to make the callout adjust automatically to the number of lines in my string? Should I modify my popoverContentSize or my label size in the UIViewController?
Thank you so much!
I have figured out how to adjust the MK Annotation callout to a UILabel.
Implement the calloutAccessoryControlTapped method
- (void)mapView:(MKMapView *)mapview annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control
{
// OPTIONAL: Deselecting Annotation View when Callout is tapped
//[mapview deselectAnnotation:view.annotation animated:YES];
NSString *calloutDetails;
IGAMapAnnotation *annotationTapped = (IGAMapAnnotation *)view.annotation;
calloutDetails = [NSString stringWithFormat:#"YOUR TEXT:\nYOURTEXT\n"];
// Declare and initialize the UIViewController that has the label to contain the callout information
IGAAnnotationInfoViewController *detailViewController = [[IGAAnnotationInfoViewController alloc]initWithText:calloutDetails];
UIPopoverController *popOver = [[UIPopoverController alloc] initWithContentViewController:detailViewController];
// Size of the UIPopoverController = size of the label + 40 pts
popOver.popoverContentSize = CGSizeMake(detailViewController.txtCallout.frame.size.width+40,detailViewController.txtCallout.frame.size.height+40);
// Show popover controller
[popOver presentPopoverFromRect:view.bounds
inView:view
permittedArrowDirections:UIPopoverArrowDirectionAny
animated:YES];
}
Now, IGAAnnotationInfoViewController.h
#interface IGAAnnotationInfoViewController : UIViewController {
CGRect calloutSize;
}
#property (strong,nonatomic) NSString *calloutInformation;
#property (strong,nonatomic) IGACalloutLabel *txtCallout;
-(IGAAnnotationInfoViewController*) initWithText : (NSString*) calloutText;
IGAAnnotationInfoViewController.m
#implementation IGAAnnotationInfoViewController
#synthesize calloutInformation,txtCallout;
-(IGAAnnotationInfoViewController*) initWithText : (NSString*) calloutText {
self = [super init];
if ( self ) {
calloutInformation = calloutText;
// Creating a label that will display the callout information (passed from IGAAcarasViewController - Map Annotation)
txtCallout = [[IGACalloutLabel alloc] initWithFrame:CGRectMake(20, 20, 0, 0)];
txtCallout.lineBreakMode = NSLineBreakByWordWrapping;
txtCallout.numberOfLines=0;
txtCallout.backgroundColor = [UIColor clearColor];
txtCallout.textColor=[UIColor blueColor];
txtCallout.text = calloutInformation;
[txtCallout drawTextInRect:CGRectMake(10,10,0,0)];
[txtCallout sizeToFit];
[self.view addSubview:txtCallout];
}
return self;
}
Finally, subclass the UILabel class:
implementation IGACalloutLabel
#synthesize topInset, leftInset, bottomInset, rightInset;
- (void)drawTextInRect:(CGRect)rect
{
UIEdgeInsets insets = {topInset,leftInset,bottomInset,rightInset};
return [super drawTextInRect:UIEdgeInsetsInsetRect(rect, insets)];
}
Regards,
I'm working on sampling the screen using AVCaptureScreenInput and outputting it using a AVCaptureVideoDataOutput, and it's not working. The images it does output are blank, but it appears like I'm doing everything right according to all the documentation I've read.
I've made sure I make the AVCaptureVideoDataOutput to something that could be read by a CGImage (kCVPixelFormatType_32BGRA). When I run this same code and have it output to a AVCaptureMovieFileOutput, the movie renders fine and everything looks good - but what I really want is a series of images.

Your data isn't planar, so there is no base address for plane 0--there's no plane 0. (To be sure, you can check with CVPixelBufferIsPlanar.) You'll need CVPixelBufferGetBaseAddress to get a pointer to the first pixel. All the data will be interleaved.
I'm trying to add a transition effect to my slideshow: here's my code
- (void)viewDidLoad
{
[super viewDidLoad];
photos = [[NSMutableArray alloc] init];
NSXMLParser *photoParser = [[NSXMLParser alloc] initWithContentsOfURL:[NSURL
URLWithString:#"http://localhost/index.xml"]];
[photoParser setDelegate:(id)self];
[photoParser parse];
currentImage = 0;
NSURL *imageURL = [NSURL URLWithString:[photos objectAtIndex:0]];
NSData *imageData = [NSData dataWithContentsOfURL:imageURL];
[imgView setImage:[UIImage imageWithData:imageData]];
timer = [NSTimer scheduledTimerWithTimeInterval: 0.5
target: self
selector: #selector(handleTimer:)
userInfo: nil
repeats: YES];
}
- (void) handleTimer: (NSTimer *) timer {
currentImage++;
if ( currentImage >= photos.count )
currentImage = 0;
NSURL *imageURL = [NSURL URLWithString:[photos objectAtIndex:currentImage]];
NSData *imageData = [NSData dataWithContentsOfURL:imageURL];
[imgView setImage:[UIImage imageWithData:imageData]];
}
- (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName
namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName
attributes:(NSDictionary *)attributeDict {
if ( [elementName isEqualToString:#"photo"]) {
[photos addObject:[attributeDict objectForKey:#"url"]];
}
}
I think I should use
[UIView transitionFromView:currentView toView:nextView duration:1.0
options:UIViewAnimationOptionTransitionCrossDissolve completion:nil];
but I don't how to fill the transitionFRomView: and toView: fields. I only have one view
Thanks for your help
You can use the method transitionWithView:duration:options:animations:completion: for which the documentation says:
You can use this block to add, remove, show, or hide subviews of the specified view.
This is an example of how you can use that method:
- (void) handleTimer: (NSTimer *) timer {
currentImage++;
if (currentImage >= photos.count) currentImage = 0;
NSURL *imageURL = [NSURL URLWithString:[photos objectAtIndex:currentImage]];
NSData *imageData = [NSData dataWithContentsOfURL:imageURL]
[UIView transitionWithView:containerView
duration:2
options:UIViewAnimationOptionTransitionFlipFromLeft
animations:^{
[imgView removeFromSuperview];
imgView = // create a new image view
[imgView setImage:[UIImage imageWithData:imageData]];
[containerView addSubview:toView];
} completion:NULL];
}
Where containerView is the parent view of imgView and most likely is self.view.
I made an App using cocos2D that has a hierarchical structure.
And I used a UIButton on glView in a child layer.
When I get back to parent layer, the button still on it's position.
I want to terminate that.
How can I do this?
Here's the code.
MainHallLayer.m

{
self = [super init];
if (self != nil)

CGFloat fontSize = 28;
{
CCLabelTTF *label = [CCLabelTTF labelWithString:#"Touch Field : Getting
touches coordinates" fontName:fontName fontSize:fontSize];
[label setColor:ccc3(0.0, 0.0, 0.0)];
label.anchorPoint = ccp(0, 0.5f);
CCMenuItem *menuItem = [CCMenuItemLabel itemWithLabel:label block:^(id

{
CCScene *scene = [TouchField1Layer node];
[ReturningNode returnToNodeWithParent:scene];
[[CCDirector sharedDirector] replaceScene:scene];
}];
[menuLists addChild:menuItem];
}
}
return self;

[self addChild:menu];
[parentNode addChild:self z:1000];
}
return self;
}
+ (id)returnToNodeWithParent:(CCNode *)parentNode
{
return [[[self alloc] initWithParentNode:parentNode] autorelease];
}
TouchField1Layer.m
- (id)init
{

if (self != nil)
{
BackgroundLayer *background = [BackgroundLayer node];
TouchField3Layer *layer = [TouchField3Layer node];
[self addChild:background z:3];
[self addChild:layer z:2];
[self preparingTools];
}
return self;
}
- (void)preparingTools
{
UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
button.frame = CGRectMake(0, 0, 100, 40);
UIView *glView = [CCDirector sharedDirector].openGLView;
glView.tag = TAG_GLVIEW;
[glView addSubview:button];
}
Any advices, helps are welcome. Always thanks. Bless You.
If you add UIKit views you will have to remove them manually at the appropriate point in time. Cocos2D does not manage the lifetime of UIKit views, only classes derived from CCNode.
For example when changing scenes you will have to remove the UIButton from the glView either in -(void) dealloc or in -(void) cleanup.
