I am trying to get a reply from a notification and pass the string to a label.
But the label (nResponse) does not change after I give the reply, why isn't the label updating? Is there a problem with the "activationType" method?
AppDelegate.h
#property (weak) IBOutlet NSTextField *nTitle;
#property (weak) IBOutlet NSTextField *nMessage;
-(IBAction)showNotification:(id)sender;
#property (weak) IBOutlet NSTextField *nResponse;
#property (assign) IBOutlet NSWindow *window;
#property BOOL hasReplyButton NS_AVAILABLE(10_9, NA);
#property (copy) NSString *responsePlaceholder NS_AVAILABLE(10_9, NA);
#property (readonly) NSAttributedString *response NS_AVAILABLE(10_9, NA);
#property (copy) NSImage *contentImage NS_AVAILABLE(10_9, NA);
#end
AppDelegate.m
#synthesize nTitle;
#synthesize nMessage;
#synthesize nResponse;
#synthesize window;
- (IBAction)showNotification:(id)sender{
NSUserNotification *notification = [[NSUserNotification alloc] init];
notification.title = [nTitle stringValue];
notification.informativeText = [nMessage stringValue];
notification.soundName = NSUserNotificationDefaultSoundName;
notification.responsePlaceholder = #"Reply";
notification.hasReplyButton = true;
[[NSUserNotificationCenter defaultUserNotificationCenter] deliverNotification:notification];
}
- (BOOL)userNotificationCenter:(NSUserNotificationCenter *)center shouldPresentNotification:(NSUserNotification *)notification;
{
if (notification.activationType == NSUserNotificationActivationTypeReplied){
NSString* userResponse = notification.response.string;
[nResponse setStringValue:userResponse]; //set label to response
NSLog(#"%#", userResponse);
}
return YES;
}
- (void)applicationDidFinishLaunching:(NSNotification *)aNotification
{
// Insert code here to initialize your application
[[NSUserNotificationCenter defaultUserNotificationCenter] setDelegate:self];
}
#end
NSUserNotificationCenter *center = [NSUserNotificationCenter defaultUserNotificationCenter];
center.delegate = self;
You should also make sure your Notice class implements the NSUserNotificationCenterDelegate protocol.

For some reason my Map wont present the Users location when button "GetLocation" is pressed. I also made sure "GetLocation" is delegated to the button on the viewcontroller. I have compared my code with others in this forum and been stuck on this matter for quite a while..

I'm trying to make a very simple iOS app where an integer is created within a MutableArray.
The integer must present itself in an label in a Custom ViewController. Here is my code:
#interface Photo : NSObject
#property (nonatomic) NSString *name;
#property (nonatomic) NSString *filename;
#property (nonatomic) NSString *naam;
#property (nonatomic) int leeftijd;
#property (nonatomic) NSString *herkomst;
#property (nonatomic) NSString *club;
#end
My Custom TableViewController with an mutableArray.
#interface PhotosTableViewController () {
NSMutableArray *photos;
}
#end
#implementation PhotosTableViewController
- (id)initWithStyle:(UITableViewStyle)style
{
self = [super initWithStyle:style];
if (self) {
// Custom initialization
}
return self;
}
- (void)viewDidLoad
{
[super viewDidLoad];
self.title = #"Soccer Players";
// Create an array
photos = [[NSMutableArray alloc]init];
Photo *pic = [[Photo alloc]init];
pic.name = #"Ronaldo";
pic.filename = #"ronaldo";
pic.naam = #"Christano Ronaldo";
pic.leeftijd = 29;
pic.herkomst = #"Portugal";
pic.club = #"Real Madrid";
[photos addObject:pic];
And at last my Custom ViewController
#interface DisplayViewController ()
#property (weak, nonatomic) IBOutlet UIImageView *currentImage;
#property (weak, nonatomic) IBOutlet UILabel *nameLabel;
#property (weak, nonatomic) IBOutlet UILabel *ageLabel;
#property (weak, nonatomic) IBOutlet UILabel *countryLabel;
#property (weak, nonatomic) IBOutlet UILabel *clubLabel;
#end
#implementation DisplayViewController
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
// Custom initialization
}
return self;
}
- (void)viewDidLoad
{
[super viewDidLoad];
UIImage *image = [UIImage imageNamed:self.currentPhoto.filename];
[self.currentImage setImage:image];
self.nameLabel.text = [self.currentPhoto naam];
self.ageLabel.text = [self.currentPhoto leeftijd];
self.countryLabel.text = [self.currentPhoto herkomst];
self.clubLabel.text = [self.currentPhoto club];
}
Not sure what i'm doing wrong. I gave the integer a Property , gave it a amount en declared it in a label. Must be something very stupid, but can't see the solution on the web.
Thanks for your help!
You should 'convert' int to string:
self.ageLabel.text = [NSString stringWithFormat:#"%d", [self.currentPhoto leeftijd]];
Integer is not auto converted to NSString. Change
self.ageLabel.text = [self.currentPhoto leeftijd];
to
self.ageLabel.text = [[self.currentPhoto leeftijd] description];
or to
self.ageLabel.text = [NSString stringWithFormat:#"%i", [self.currentPhoto leeftijd]];
Lable only show NSString so you convert your int to NSString..
self.ageLabel.text = [NSString stringWithFormat:#"%d", [self.currentPhoto leeftijd]];
I nearly followed this post. The viewcontroller will push via storyboard. Here the relevant code:
ViewController.m:
-(void)mapView:(MKMapView *)mapView annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control
{
NSLog(#"%#", view.annotation.title);
MapPoint *annView = view.annotation;
DetailViewController *dvc = [self.storyboard instantiateViewControllerWithIdentifier:#"DetailViewController"];
dvc.title = #"my own Details";
dvc.titleTMP = annView.title;
dvc.subtitleTMP = annView.subtitle;
[self.navigationController pushViewController:dvc animated:YES];
}
MapPoint.h:
#interface MapPoint : NSObject <MKAnnotation>
{
NSString *_title;
NSString *_subtitle;
CLLocationCoordinate2D _coordinate;
UIImage *_storeImage;
}
#property (copy) NSString *title;
#property (copy) NSString *subtitle;
#property (nonatomic, readonly) UIImage *storeImage;
#property (nonatomic, readonly) CLLocationCoordinate2D coordinate;
- (id)initWithTitle:(NSString*)title subtitle:(NSString*)subtitle coordinate:(CLLocationCoordinate2D)coordinate storeImage:(UIImage*)storeImage;
and DetailViewController:
#interface DetailViewController : UIViewController
#property (strong, nonatomic) IBOutlet UIImageView *branchImage;
#property (strong, nonatomic) IBOutlet UILabel *titleLabel;
#property (strong, nonatomic) IBOutlet UITextView *textView;
I think my mistake is in the calloutAccessoryControlTapped method but I dont know what is the real reason for this issue.
If you use a storyboard, can use prepareForSegue method and set within a class similarly as you have made.
I post a portion of code
-(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender{
if([segue.identifier isEqualToString:#"Brs"]){
NSLog(#"segue %# ",[segue identifier]);
[segue.destinationViewController setPath:[ris_xml objectAtIndex:index_post-1] ];
}
}
In this example I set attribute "Path" of next UIViewController only if his identifier is "Brs".
For use this method is need set UIviewController identifier into storyboard right panel.
Using this isn't need to instantiate new UIViewController if you have it in storyboard.
I solved it by thinking about loading sequence.
All what to do is create temporary #properties
#interface DetailViewController : UIViewController
#property (strong, nonatomic) IBOutlet UIImageView *branchImage;
#property (strong, nonatomic) IBOutlet UILabel *titleLabel;
#property (strong, nonatomic) IBOutlet UITextView *textView;
#property (nonatomic) NSString *titleTMP; //added
#property (nonatomic) NSString *subtitleTMP; //added
and do
-(void)mapView:(MKMapView *)mapView annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control
{
NSLog(#"%#", view.annotation.title);
MapPoint *annView = view.annotation;
DetailViewController *dvc = [self.storyboard instantiateViewControllerWithIdentifier:#"DetailViewController"];
dvc.title = #"my own Details";
dvc.titleTMP = annView.title;
dvc.subtitleTMP = annView.subtitle;
[self.navigationController pushViewController:dvc animated:YES];
}
The DetailViewController:
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view.
titleLabel.text = titleTMP;
textView.text = subtitleTMP;
}
In my app I have two views: a mapView, and a detail view. The mapView has annotations, and the annotation views have right callout buttons that push the detail view onto the stack when the callout button is pressed. In the detail view, the user can take a picture that appears on the UIImage that is on the detail view controller. What I want is for a different image to be on the detail view controller for each annotation. I have read that I can use a singleton, and I have made a singleton class, but I do not know how to use it. Can someone help me out?
Here is some code:
My MKAnnotation class:
#import <CoreLocation/CoreLocation.h>
#import <MapKit/MapKit.h>
#interface MapPoint : NSObject <MKAnnotation>
{
NSString *_address;
CLLocationCoordinate2D _coordinate;
NSNumber *_identifier;
UIImage *_image;
}
- (id)initWithAddress:(NSString*)address
coordinate:(CLLocationCoordinate2D)coordinate
title:(NSString *)t
identifier:(NSNumber *)ident;
//This is a required property from MKAnnotation
#property (nonatomic, readonly) CLLocationCoordinate2D coordinate;
//This is an optional property from MKAnnotataion
#property (nonatomic, copy) NSString *title;
#property (nonatomic, readonly, copy) NSString *subtitle;
#property (nonatomic) BOOL animatesDrop;
#property (nonatomic) BOOL canShowCallout;
#property (copy) NSString *address;
#property (copy) NSNumber *identifier;
#property (copy,nonatomic) UIImage *image;
#end
#implementation MapPoint
#synthesize title, subtitle, animatesDrop, canShowCallout;
#synthesize address = _address, coordinate = _coordinate, identifier = _identifier, image = _image;
-(id)initWithAddress:(NSString *)address
coordinate:(CLLocationCoordinate2D)coordinate
title:(NSString *)t
identifier:(NSNumber *)ident
{
self = [super init];
if (self) {
_address = [address copy];
_coordinate = coordinate;
_identifier = ident;
[self setTitle:t];
NSDate *theDate = [NSDate date];
subtitle = [NSDateFormatter localizedStringFromDate:theDate
dateStyle:NSDateFormatterMediumStyle
timeStyle:NSDateFormatterMediumStyle];
}
return self;
}
#end
Here is the detail view controller:
#import <UIKit/UIKit.h>
#class P2OViewController;
#interface PinViewController : UIViewController <UINavigationControllerDelegate, UIImagePickerControllerDelegate,UITextFieldDelegate>
{
__weak IBOutlet UILabel *label;
__weak IBOutlet UIButton *removeButton;
NSString *addressForLabel;
__weak P2OViewController *_vc;
__weak NSNumber *_identifier;
}
#property (weak, nonatomic) IBOutlet UIImageView *imageView;
#property (weak, nonatomic) IBOutlet UILabel *label;
#property (weak, nonatomic) IBOutlet UIButton *removeButton;
#property (weak, nonatomic) P2OViewController *vc;
#property (weak, nonatomic) NSNumber *identifier;
-(void)takePicture:(id)sender;
-(void)buttonPressed:(id)sender;
#end
#import "PinViewController.h"
#import "MapPoint.h"
#import "P2OViewController.h"
#implementation PinViewController
#synthesize imageView, label, removeButton;
#synthesize vc = _vc, identifier = _identifier;
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
UIBarButtonItem *pic = [[UIBarButtonItem alloc]initWithBarButtonSystemItem:UIBarButtonSystemItemCamera
target:self
action:#selector(takePicture:)];
[[self navigationItem]setRightBarButtonItem:pic];
}
return self;
}
-(void)takePicture:(id)sender
{
UIImagePickerController *imagePicker = [[UIImagePickerController alloc]init];
//If our device has a camera, we ant to take a picture, otherwise, we just pick from photo library
if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]) {
[imagePicker setSourceType:UIImagePickerControllerSourceTypeCamera];
} else {
[imagePicker setSourceType:UIImagePickerControllerSourceTypePhotoLibrary];
}
[imagePicker setDelegate:self];
//Place the image picker on the screen
[self presentViewController:imagePicker
animated:YES
completion:nil];
}
-(void)imagePickerController:(UIImagePickerController *)picker
didFinishPickingMediaWithInfo:(NSDictionary *)info
{
//Get picked image from info dictionary
UIImage *image = [info objectForKey:UIImagePickerControllerOriginalImage];
//Put the image onto the screen in out image view
[imageView setImage:image];
//Take image picker off the screen - you must call this dismiss method
[self dismissViewControllerAnimated:YES
completion:nil];
}
#end
You surely have a class implementing the MKAnnotation protocol.
In this class simply add a UIImage property and assign to every annotation its custom image.
Then when presenting the detailed view you just pass around the annotation and access its image property you defined.
EDIT
In your PinViewController simply declare a property like this
#property(nonatomic, strong) MapPoint * annotation;
Before you present your PinViewController assign the corresponding annotation to it, doing something like
detailedController.annotation = theAnnotation;
Do whatever you need to do to get the image, then store it in the annotation in this way
self.annotation.image = theImage;
Now the annotation is storing the image, so as long as you keep it in memory it will be there available for you.
The next time you push the detailed view you can perform a check to see whether that annotation has already an image or not
if(nil != self.annotation.image) {
// do something
} else {
// do something else
}
I'm sure there is a simple explanation for this.
I am looking to transfer the data (not store) but transfer the text the user types into a text field and display it as a UILabel in another ViewController.
I already know how to convert text entered by the user into a label on the same viewcontroller.
I guess my problem is importing.
the .h:
#interface ViewController : UIViewController {
IBOutlet UITextField *firstPerson;
IBOutlet UITextField *secondPerson;
IBOutlet UIButton *calculateButton;
NSString *firstName;
NSString *secondName;
}
#property (nonatomic, retain) IBOutlet UITextField *firstPerson;
#property (nonatomic, retain) IBOutlet UITextField *secondPerson;
#property (nonatomic, retain) NSString *firstName;
#property (nonatomic, retain) NSString *secondName;
#property (nonatomic, retain) IBOutlet UIButton *calculateButton;
-(IBAction)calculate;
#end
the .m:
-(IBAction)calculate {
//Linked to UIButton
//This is the first View Controller.
// firstName = firstPerson.text;
// secondName = secondPerson.text;
secondViewController = [[ShowStats alloc] init];
}
my secondview controller .m (ShowStats):
#import "ShowStats.h"
#import "ViewController.h"
- (void)viewDidLoad
{
firstName = firstPerson.text;
secondName = secondPerson.text;
[super viewDidLoad];
}
Many thanks!
EDIT
ViewController.h
#import <UIKit/UIKit.h>
#import "ShowStats.h"
#interface ViewController : UIViewController {
IBOutlet UITextField *firstPerson;
IBOutlet UITextField *secondPerson;
IBOutlet UIButton *calculateButton;
//NSString *firstName;
// NSString *secondName;
}
#property (nonatomic, retain) IBOutlet UITextField *firstPerson;
#property (nonatomic, retain) IBOutlet UITextField *secondPerson;
//#property (nonatomic, retain) NSString *firstName;
//#property (nonatomic, retain) NSString *secondName;
#property (nonatomic, retain) IBOutlet UIButton *calculateButton;
-(IBAction)calculate;
#end
ViewController.m
#import "ViewController.h"
#import "ShowStats.h"
#implementation ViewController
#synthesize firstPerson, secondPerson;
//#synthesize firstName, secondName;
#synthesize calculateButton;
ShowStats *secondViewController;
-(IBAction)calculate {
secondViewController = [[ShowStats alloc] init];
secondViewController.firstName = firstPerson.text;
}
ShowStats.h
#interface ShowStats : UIViewController{
IBOutlet UILabel *nameStats;
}
#property (nonatomic, retain) IBOutlet UILabel *nameStats;
#property (nonatomic, retain) NSString *firstName;
#property (nonatomic, retain) NSString *secondName;
#end
ShowStats.m
- (void)viewDidLoad
{
nameStats.text = [NSString stringWithFormat:#"%#", firstName];
//secondLabel.text = self.secondName;
[super viewDidLoad];
}
Make these properties in ShowStats class
#property (nonatomic, retain) NSString *firstName;
#property (nonatomic, retain) NSString *secondName;
and change this to this
-(IBAction)calculate {
secondViewController = [[ShowStats alloc] init];
secondViewController.firstName = firstPerson.text;
secondViewController.secondName = secondPerson.text;
}
then set these strings to UILablel in your viewDidLoad
In ShowStats.h, add the following:
#property(nonatomic, copy) NSString* firstName;
#property(nonatomic, copy) NSString* secondName;
In ShowStats.m add/update the following:
#synthesize firstName, secondName;
//...
- (id) init {
if (self = [super init]) {
self.firstName = nil;
self.secondName = nil;
//...
}
return self;
}
- (void) dealloc {
self.firstName = nil;
self.secondName = nil;
//...
[super dealloc];
}
- (void)viewDidLoad {
//or even better, do this in viewWillAppear instead
firstLabel.text = self.firstName;
secondLabel.text = self.secondName;
//...
[super viewDidLoad];
}
Finally, in ViewController.m, implement calculate like this:
-(IBAction)calculate {
//Linked to UIButton
//This is the first View Controller.
// firstName = firstPerson.text;
// secondName = secondPerson.text;
secondViewController = [[ShowStats alloc] init];
secondViewController.firstName = firstPerson.text;
secondViewController.secondName = secondPerson.text;
//display the view controller here
[secondViewController autorelease];
}
If it is a navigation then in your SecondViewController you can call:
ViewController *viewController = [self.navigationController.viewControllers objectAtIndex:0];
firstName = [[viewController firstPerson] text];
secondName = [[viewController secondPerson] text];
Or you could do the following for a Single View app:
AppDelegate *appDelegate = [[UIApplication sharedApplication] delegate];
ViewController *viewController = [appDelegate viewController];
firstName = [[viewController firstPerson] text];
secondName = [[viewController secondPerson] text];
* EDIT *
Add two labels to your .h file (nonatomic, retain) & synthesize in .m . Initialize the labels in viewDidLoad then set them (assuming they are called label1 and label2):
[label1 setText:firstName];
[label2 setText:secondName];
