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 have a UIImageView that is called upon programatically, I am trying to get it to spin around but its not working. The image will be placed inside a dynamic UITableView (I cannot change it to static). The image appears fine in my table view but it just doesn't spin.
- (void)viewDidLoad
{
[super viewDidLoad];
UIImageView *imageView = [[UIImageView alloc] initWithFrame:CGRectMake(20, 122, 38, 38)];
imageView.image = [UIImage imageNamed:#"settings1.png"];
[self.view addSubview:imageView];
CABasicAnimation *spin;
spin = [CABasicAnimation animationWithKeyPath:#"transform.rotation"];
spin.fromValue = [NSNumber numberWithFloat:0];
spin.toValue = [NSNumber numberWithFloat:((360*M_PI)/180)];
spin.duration = 4;
spin.repeatCount = 10*1000;
[imageView.layer addAnimation:spin forKey:#"360"];
It's probably because you're trying to start the animation in viewDidLoad. I'd suggest reorganizing your code in such a way that you create the image view instance in viewDidLoad, but then wait until viewDidAppear: is called to actually start the animation.
#property (strong, nonatomic) UIImageView *imageView;
And then
- (void)viewDidLoad
{
[super viewDidLoad];
self.imageView = [[UIImageView alloc] initWithFrame:CGRectMake(20, 122, 38, 38)];
self.imageView.image = [UIImage imageNamed:#"settings1.png"];
[self.view addSubview:self.imageView];
}
- (void)viewDidAppear:(BOOL)animated
{
[super viewDidAppear:animated];
CABasicAnimation *spin = [CABasicAnimation animationWithKeyPath:#"transform.rotation"];
spin.fromValue = [NSNumber numberWithFloat:0];
spin.toValue = [NSNumber numberWithFloat:((360*M_PI)/180)];
spin.duration = 4;
spin.repeatCount = 10*1000;
[self.imageView.layer addAnimation:spin forKey:#"360"];
}
I must be doing something wrong here:
My Cocoa app has a scrollview around a custom view which in turn has a textview. I only expect to see one "This is a " string but there the extra one up in the corner.
I have reduced the code to something very minimal and still do not understand what my error is, so here I am fishing for a clue.
The view controller for the custom view follows, but for simplicity here is a link to the project.
#import "TTTSimpleCtrlView.h"
#interface TTTSimpleCtrlView ()
#property (strong,nonatomic) NSTextView *tv1;
#property (strong,nonatomic) NSTextStorage *ts;
#end
#implementation TTTSimpleCtrlView
- (void) awakeFromNib {
NSFont *font = [NSFont fontWithName:#"Courier New Bold" size:20.0f];
NSMutableParagraphStyle *styleModel = [[NSParagraphStyle defaultParagraphStyle] mutableCopy];
[styleModel setLineHeightMultiple:1.0];
// [styleModel setLineSpacing:fontRect.size.height * 2];
NSDictionary *textAttrs = [NSDictionary dictionaryWithObjectsAndKeys: font, NSFontAttributeName,
[NSColor blackColor] ,NSForegroundColorAttributeName,
[NSColor whiteColor], NSBackgroundColorAttributeName,
styleModel, NSParagraphStyleAttributeName,
nil];
NSString *pilcrowStr = #"This is a test.";
NSAttributedString *s = [[NSAttributedString alloc] initWithString:pilcrowStr attributes:textAttrs];
NSRect rect = [s boundingRectWithSize:NSMakeSize(INFINITY,INFINITY)options:0];
NSLayoutManager *lm = [[NSLayoutManager alloc] init];
NSTextContainer *tc = [NSTextContainer new];
[tc setContainerSize:s.size];
[lm addTextContainer:tc];
_ts = [[NSTextStorage alloc] init];
[_ts setAttributedString:s];
[_ts addLayoutManager:lm];
[lm replaceTextStorage:_ts];
rect.origin.x = 10;
rect.origin.y = rect.size.height;
NSTextView *v = [[NSTextView alloc] initWithFrame:rect textContainer:tc];
[v setDrawsBackground:YES];
[self addSubview:v];
}
- (BOOL) isFlipped {
return YES;
}
- (void)drawRect:(NSRect)rect
{
NSLog(#"drawRect & %lu subviews",self.subviews.count);
for (NSTextView *v in self.subviews) {
if(CGRectIntersectsRect(v.frame, rect) || CGRectContainsRect(rect, v.frame)) {
[v drawRect:rect];
NSLog(#"frame = %#",NSStringFromRect(v.frame));
}
}
[super drawRect:rect];
}
You are calling:
[super drawRect:rect];
and you are drawing the text yourself in your draw function.
In effect you are drawing the text and cocoa is drawing the text for you as well.
So don't call super.
I am launching detail pages from a UITableView and within that detail page there is an image. I would like it to be zoomable, so I'd like the contents of that detail page to sit inside a scrollView. So far no luck, the labels, textviews and images are fine, but I can't get the ScrollView implemented.
here is my .m: THANKS!

I think that you're missing the following line to add the UIScrollView as a subview.
[self.view addSubView:scrollView];
i have implemented the following viewDidLoad() Method:
- (void)viewDidLoad {
[super viewDidLoad];
// loading images into the queue
loadImagesOperationQueue = [[NSOperationQueue alloc] init];
AFOpenFlowView *openFlow = self.view;
theControl = [[UIControl alloc] initWithFrame:self.view.frame];
NSString *imageName;
btn = [UIButton buttonWithType:UIButtonTypeCustom];
btn.frame = CGRectMake(10, 10, 40, 40);
[btn addTarget:self action:#selector(testMethode) forControlEvents:UIControlEventTouchUpInside];
[btn setTitle:#"<<" forState:UIControlStateNormal];
[btn setHidden:YES];
[theControl addSubview:btn];
for (int i=0; i < 10; i++) {
imageName = [[NSString alloc] initWithFormat:#"cover_%d.jpg", i];
imageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:imageName]];
UIImage *aktuellesImage = imageView.image;
UIImage *scaledImage = [aktuellesImage scaleToSize:CGSizeMake(100.0f, 100.0f)];
[openFlow setImage:scaledImage forIndex:i];
// [(AFOpenFlowView *)self.view setImage:scaledImage forIndex:i];
[imageName release];
[aktuellesImage release];
}
[theControl addSubview:openFlow];
[theControl setUserInteractionEnabled:YES];
[(AFOpenFlowView *)self.view setNumberOfImages:10];
}
And the following touchesEnded() Method:
- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event {
[btn setHidden:NO];
}
But the touchesEnded doesn't work, and the Button will not shown when i touch the picture, does anybody know what is the Problem???
Greetings Marco
Make sure your view has user interaction enabled in order to register touches. This can be set in your View Controller thusly:
self.view.userInteractionEnabled = YES;
