I am trying to find a way to make multiple annotation disclosure buttons open other views.
For example, annotation1 disclosure button needs to open ViewController 1.xib, annotation2 needs to open ViewController2.xib, and so on. Is this possible?
I've got this code so far, which sets the location according to coordinates, and sets the user location.
- (void)viewDidLoad
{
[super viewDidLoad];
_mapView.showsUserLocation = YES;
CLLocationCoordinate2D annotationCoord;
annotationCoord.latitude = 40.714353;
annotationCoord.longitude = -74.005973;
coord = 1;
MKPointAnnotation *annotationPoint = [[MKPointAnnotation alloc] init];
annotationPoint.coordinate = annotationCoord;
annotationPoint.title = #"New York";
[_mapView addAnnotation:annotationPoint];
CLLocationCoordinate2D annotationCoord1;
annotationCoord1.latitude = 51.511214;
annotationCoord1.longitude = -0.119824;
coord = 2;
MKPointAnnotation *annotationPoint1 = [[MKPointAnnotation alloc] init];
annotationPoint1.coordinate = annotationCoord1;
annotationPoint1.title = #"London";
[_mapView addAnnotation:annotationPoint1];
}
- (MKAnnotationView *)mapView:(MKMapView *)map viewForAnnotation:(id <MKAnnotation>)annotation
{
MKPinAnnotationView *mapPin = nil;
if(annotation != map.userLocation)
{
static NSString *defaultPinID = #"defaultPin";
mapPin = (MKPinAnnotationView *)[map dequeueReusableAnnotationViewWithIdentifier:defaultPinID];
if (mapPin == nil )
{
mapPin = [[[MKPinAnnotationView alloc] initWithAnnotation:annotation
reuseIdentifier:defaultPinID] autorelease];
mapPin.canShowCallout = YES;
UIButton *infoButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
mapPin.rightCalloutAccessoryView = infoButton;
}
else
mapPin.annotation = annotation;
}
return mapPin;
}
What do I put into here:
- (void)mapView:(MKMapView *)mapView annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control
{
// ???
}
All help is appreciated. Thanks
You could do something like this,
- (void)mapView:(MKMapView *)mapView annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control
{
if ([view.annotation.title isEqualToString:#"The titel of your annotation"])
{
// Do something
}
}

I have been trying to figure this issue out for days now with no luck, any advice would be greatly appreciated.
I have a uitableviewcontroller that loads data from core data. When the tableview loads, the first 6 (no matter how many objects are actually saved) are loaded. When I begin to scroll down, all of the following cells are labeled "(null)". When I go back up to the top, the data in the original 6 cells are replaced with "(null)". When I logged the contents of the array from the fetch, all of the objects from core data get logged, but when I log the contents of the cell, the first 6 contents get logged, the a long list of rows with (null) get logged.
I've tried a lot of differnet things to debug this, but nothing has worked so far.
Here is the tableviewcontroller file

Well maybe this is your problem.
if ([self.search isEqual:#0]){
I think you are initially fetching the data but than once you init the searchController it starts looking for the searchResults.
The code you are looking is:
if ([self.search isActive]){
I found the solution. I changed
AppDelegate *del = [[AppDelegate alloc] init];
NSManagedObjectContext *context = del.managedObjectContext;
to
AppDelegate *del = [[UIApplication sharedApplication] delegate];
NSManagedObjectContext *context =[del managedObjectContext];
and it works perfectly.
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)];
}

I've a problem with Annotation when clicked and send data to "Prepare to segue"

}
I would like to understand how to recognize some annotation is pressed and send the data to the next page through "PrepareForSegue".
Does anyone know how to help me? I'm going crazy.
Thanks in advance.
You will simply want to use the mapView:didSelectAnnotationView: delegate call.
https://developer.apple.com/documentation/mapkit/mkmapviewdelegate/1452393-mapview
From in mapView:didSelectAnnotationView, call the segue call via the performSegueWithIdentifier.
[self performSegueWithIdentifier:#"Prova" sender:self];
Assuming you setup "note1" from within mapView:didSelectAnnotationView based on the annotation selected.
my app is showing the map in the right way, but the annotation (the pin of a place choosen by me) isn't displayed... why?
- (void)viewDidLoad{
[super viewDidLoad];
CLLocationCoordinate2D zoomLocation;
zoomLocation.latitude = 45.40170;
zoomLocation.longitude = 8.91552;
MKCoordinateRegion viewRegion = MKCoordinateRegionMakeWithDistance(zoomLocation, METERS_PER_MILE, METERS_PER_MILE);
[_mappa setRegion:viewRegion animated:YES];
[_mappa regionThatFits:viewRegion];
MKPointAnnotation *point = [[MKPointAnnotation alloc] init];
point.coordinate = zoomLocation;
point.title = #"TITLE";
point.subtitle = #"SUBTITLE";
[_mappa addAnnotation:point];
}
sorry but i'm new to xcode, for smartphone, i've developed only on android
Your code appears to add the annotation to the MKMapView correctly, but you need to provide an annotation view for the annotation by implementing delegate method mapView: viewForAnnotation: in your view controller, like this:
- (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id <MKAnnotation>)annotation {
static NSString *identifier = #"MyLocation";
MKPinAnnotationView *annotationView = (MKPinAnnotationView *) [_mapView dequeueReusableAnnotationViewWithIdentifier:identifier];
if (annotationView == nil) {
annotationView = [[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:identifier];
} else {
annotationView.annotation = annotation;
}
annotationView.enabled = YES;
annotationView.canShowCallout = YES;
return annotationView;
}
Assuming you're using interface builder, make sure you set the MKMapView's delegate to your view controller.
At the moment I have an NSTableView with a custom NSTextFieldCell that holds an NSAttributedString with some ranges with the NSLinkAttribute. I tried to integrate code from Apple's TableViewLinks example and Toomas Vather's HyperlinkTextField.
I implemented the -trackMouse Function like this:
- (BOOL)trackMouse:(NSEvent *)theEvent inRect:(NSRect)cellFrame ofView:(NSView *)controlView untilMouseUp:(BOOL)flag {
BOOL result = YES;
NSUInteger hitTestResult = [self hitTestForEvent:theEvent inRect:cellFrame ofView:controlView];
if ((hitTestResult & NSCellHitContentArea) != 0) {
result = [super trackMouse:theEvent inRect:cellFrame ofView:controlView untilMouseUp:flag];
theEvent = [NSApp currentEvent];
hitTestResult = [self hitTestForEvent:theEvent inRect:cellFrame ofView:controlView];
if ((hitTestResult & NSCellHitContentArea) != 0) {
NSAttributedString* attrValue = [self.objectValues objectForKey:#"theAttributedString"];
NSMutableAttributedString* attributedStringWithLinks = [[NSMutableAttributedString alloc] initWithAttributedString:attrValue];
//HOW TO GET A RIGHT INDEX?
NSTableView* myTableView = (NSTableView *)[self controlView];
NSPoint eventPoint = [myTableView convertPoint:[theEvent locationInWindow] fromView:nil];
NSInteger myRow = [myTableView rowAtPoint:eventPoint];
NSRect myBetterViewRect = [myTableView rectOfRow:myRow];
__block NSTextView* myTextView = [[NSTextView alloc] initWithFrame:myBetterViewRect];
[myTextView.textStorage setAttributedString:attributedStringWithLinks];
NSPoint localPoint = [myTextView convertPoint:eventPoint fromView:myTableView];
NSUInteger index = [myTextView.layoutManager characterIndexForPoint:localPoint inTextContainer:myTextView.textContainer fractionOfDistanceBetweenInsertionPoints:NULL];
if (index != NSNotFound)
{
NSMutableArray* myHyperlinkInfos = [[NSMutableArray alloc] init];
NSRange stringRange = NSMakeRange(0, [attrValue length]);
[attrValue enumerateAttribute:NSLinkAttributeName inRange:stringRange options:0 usingBlock:^(id value, NSRange range, BOOL* stop)
{
if (value)
{
NSUInteger rectCount = 0;
NSRectArray rectArray = [myTextView.layoutManager rectArrayForCharacterRange:range withinSelectedCharacterRange:range inTextContainer:myTextView.textContainer rectCount:&rectCount];
for (NSUInteger i = 0; i < rectCount; i++)
{
[myHyperlinkInfos addObject:#{kHyperlinkInfoCharacterRangeKey : [NSValue valueWithRange:range], kHyperlinkInfoURLKey : value, kHyperlinkInfoRectKey : [NSValue valueWithRect:rectArray[i]]}];
}
}
}];
for (NSDictionary* info in myHyperlinkInfos)
{
NSRange range = [[info objectForKey:kHyperlinkInfoCharacterRangeKey] rangeValue];
if (NSLocationInRange(index, range))
{
NSURL* url = [NSURL URLWithString:[info objectForKey:kHyperlinkInfoURLKey]];
[[NSWorkspace sharedWorkspace] openURL:url];
}
}
}
}
}
return result;}
The character-Index when clicking into the cell's (nstextview's) text appears not to fit. So even if there are more than one link in the text, usually the last link is opened. My guess is that I don´t get the nsrect of the clicked cell. If so, how could I get the right NSRect?
I am glad for any suggestions, comments, code pieces - or simpler solutions (even if this would include switching to a view-based tableview).
Thanks.
