I have two files and I am trying to pass some information between them. Basically I have a Boolean Property that I use to decide what part of a method I should use. I created an instance method that returns this boolean property for viewing. In my first controller I create the property and set it and make the method and in my second controller I create an instance of the class and call the method to see what value the BOOL is. The problem is that I do not get the right answer when I call it, I always get 0. Can someone explain why? Thanks. In the Second File I have a mapView using annotations so the title property gets called on a click of the pin on the map
First File: TableViewController
#import "MyTableViewController.h"
#import "FlickrFetcher.h"
#import "myTableViewControllerPhotoLocation.h"
#import "FlickrImageViewController.h"
#import "FlickrPhotoSort.h"
#import "MapViewController.h"
#import "FlickrPhotoAnnotation.h"
@interface MyTableViewController () <MapViewControllerDelegate>
//This is declared in header
@property bool photoStage;
@end
@implementation MyTableViewController
@synthesize photoStage= _photoStage;
-(BOOL) currentPhotoStage{
NSLog(@"PhotoStage = %@", self.photoStage);
return self.photoStage;
}
-(void) setphotoStage: (bool) photoStage{
if(!_photoStage) _photoStage = NO;
else {
_photoStage = photoStage;
}
}
-(NSArray*) mapAnnotations{
NSMutableArray *annotations= [NSMutableArray arrayWithCapacity:[self.photoArray count]];
for(NSDictionary *photo in self.photoArray)
{
[annotations addObject:[FlickrPhotoAnnotation annotationForPhoto:photo]];
}
//I set the value of self.photoStage here
self.photoStage = YES;
//Prints out 1
NSLog(@"%d", self.photoStage);
return annotations;
}
Second File called PhotoAnnotation
#import "FlickrPhotoAnnotation.h"
#import "FlickrFetcher.h"
#import "MapKit/Mapkit.h"
#import "MapViewController.h"
#import "MyTableViewController.h"
@interface FlickrPhotoAnnotation ()
@property (nonatomic,strong) MyTableViewController* mapCheck;
@end
@implementation FlickrPhotoAnnotation
@synthesize photo=_photo; //This is a dictionary
@synthesize mapCheck = _mapCheck;
Problem occurs here
-(NSString*) title{ //gets called on click of annotation in map
// ALWAYS RETURNS 0 hence if statement fails
NSLog(@"photoStage = %d", [self.mapCheck currentPhotoStage]);
if([self.mapCheck currentPhotoStage])
{
NSLog(@"title = %@", [self.photo objectForKey:FLICKR_PHOTO_TITLE]);
NSString *title = [self.photo objectForKey:FLICKR_PHOTO_TITLE];
if([title isEqualToString:@""]) title = @"No Title";
NSLog(@"title = %@", title);
return title;
}else {
NSString * cellTitle = [self.photo objectForKey:@"_content"];
NSRange cellRange = [cellTitle rangeOfString:@","];
NSString * cellMainTitle = [cellTitle substringToIndex:cellRange.location];
return cellMainTitle;
//[self.photo objectForKey:FLICKR_PHOTO_TITLE];
}
}
