Loading a dictionary from a navigation bar title - ios

Question

I have a mainViewController which pushes a detailViewController onto the screen.
The items (images, navigation bar title, textview, and a button) in the detailViewController are all loaded from an NSMutableDictionary in the MainViewController depending on which image in it is tapped.
I also have a button in the detailViewController that when selected loads a mapview which shows the user's location. When the user taps a button a pin is dropped marking this location with a annotation callout title.
I want the title of the mapview and the annotation title to be the same as the detailViewController's which is loaded from the MainViewController's NSMutableDictionary.
Right now I am trying to use the detailViewController's title as the determining factor in the mapview's title and annotation title. However this isn't working.
Here is my code in MainViewController .m.
- (void) coverflowView:(TKCoverflowView*)coverflowView coverAtIndexWasDoubleTapped:(int)index{
SomeDetailViewController *detailViewController = [[SomeDetailViewController alloc] initWithNibName:#"SomeDetailViewController" bundle:nil];
if ((int)index == 0) {
NSMutableDictionary *myDictionary = [NSMutableDictionary dictionaryWithObjectsAndKeys:
#"0002.jpg", #"imagekey",
#"This is tree 0002", #"textkey",
#"0002.image.png",#"imagekey2",
#"0002 title", #"headerkey",
#"www.0003.com", #"address",nil];
NSLog(#"%#", [myDictionary objectForKey:#"imagekey"]);
NSLog(#"%#", [myDictionary objectForKey:#"textkey"]);
NSLog(#"%#", [myDictionary objectForKey:#"imagekey2"]);
NSLog(#"%#", [myDictionary objectForKey:#"address"]);
NSLog(#"%#", [myDictionary objectForKey:#"headerkey"]);
detailViewController.myDictionary = myDictionary;
}
else if ((int)index == 1) {
NSMutableDictionary *myDictionary = [NSMutableDictionary dictionaryWithObjectsAndKeys:
#"0003.jpg", #"imagekey",
#"This is 0003", #"textkey",
#"0003.image.png",#"imagekey2",
#"0003 title", #"headerkey",
#"www.0003.com", #"address",nil];
NSLog(#"%#", [myDictionary objectForKey:#"imagekey"]);
NSLog(#"%#", [myDictionary objectForKey:#"textkey"]);
NSLog(#"%#", [myDictionary objectForKey:#"imagekey2"]);
NSLog(#"%#", [myDictionary objectForKey:#"address"]);
NSLog(#"%#", [myDictionary objectForKey:#"headerkey"]);
detailViewController.myDictionary = myDictionary;
}
[self.navigationController pushViewController:detailViewController animated:YES];
}
Here is my code in the detailViewController.m.
This loads my Dictionary strings (The bold part is loading the navigation bar title).
- (void)viewDidLoad {
NSString *filePath =[self pathOfFile];
if ([[NSFileManager defaultManager]fileExistsAtPath:filePath]){
NSArray *array = [[NSArray alloc]initWithContentsOfFile:filePath];
myText.text = [array objectAtIndex:0];
}
UIApplication *app = [UIApplication sharedApplication];
[[NSNotificationCenter defaultCenter]addObserver:self selector:#selector(applicationWillTerminate:) name:UIApplicationWillTerminateNotification object:app];
[super viewDidLoad];
imageView .image = [[UIImage alloc] init];
self.imageView.image =[UIImage imageNamed:[(NSMutableDictionary *)myDictionary objectForKey:#"imagekey"]];
imageView2 .image = [[UIImage alloc] init];
self.imageView2.image =[UIImage imageNamed:[(NSMutableDictionary *)myDictionary objectForKey:#"imagekey2"]];
self.myText.text =[(NSMutableDictionary *)myDictionary objectForKey:#"textkey"];
**self.navigationItem.title = [(NSMutableDictionary *)myDictionary objectForKey:#"headerkey"];**
NSLog(#"%#", [myDictionary objectForKey:#"imagekey"]);
NSLog(#"%#", [myDictionary objectForKey:#"imagekey2"]);
NSLog(#"%#", [myDictionary objectForKey:#"textkey"]);
NSLog(#"%#", [myDictionary objectForKey:#"headerkey"]);
}
Here is where I am trying to load the navigation bar title and annotation title using the current navigation bar title as the determining factor.
This is the only thing I can think of to use since there is no stable element. Everything in the detailViewController is loaded from the MainViewController NSDictionary.
-(IBAction)pushMap:(id) sender{
SomePositionViewController *somePosition = [[SomePositionViewController alloc] init];
if ((self.navigationItem.title = #"0002 title")) {
NSMutableDictionary *mapDictionary = [NSMutableDictionary dictionaryWithObjectsAndKeys:
#"0002a title", #"headerkey2",
#"0002 annotation title", #"titlekey",nil];
treePosition.mapDictionary = mapDictionary;
NSLog(#"%#", [mapDictionary objectForKey:#"titlekey"]);
NSLog(#"%#", [mapDictionary objectForKey:#"headerkey2"]);
}
else if((self.navigationItem.title = #"0003 title")) {
NSMutableDictionary *mapDictionary = [NSMutableDictionary dictionaryWithObjectsAndKeys:
#"0003a title", #"headerkey2",
#"0003 annotation title", #"titlekey",nil];
treePosition.mapDictionary = mapDictionary;
NSLog(#"%#", [mapDictionary objectForKey:#"titlekey"]);
NSLog(#"%#", [mapDictionary objectForKey:#"headerkey2"]);
}
[self.navigationController pushViewController:somePosition animated:YES];
}
Does anyone have any idea how I can accomplish this? I have been wracking my brain but to no avail. HELP!

Answer 1

One thing I spotted is that you are comparing strings the wrong way. You use
if ((self.navigationItem.title = #"0002 title"))
but should use
if (([self.navigationItem.title isEqualToString:#"0002 title"]))
Comparing strings in your way will always fail.
