I am attempting to pass information from one viewController to another using a push segue with an IBAction button named *line. However from what I can tell this method is not being called and the NSLog(#"%#", see); I inserted to test the method is not displaying any message. Here is some code for the first viewController.

Thanks for any suggestions on why this method is not being called when the button is pushed
The only way for your IBAction to NOT get called is when the button is not appropriately connected to it. Double check that in the connections inspector.
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;
}
I am showing data in a UITableView with a thumbnail image. Initially, when the cell is clicked on, I would reload the image from the server which would take additional time, resources, and memory. Instead of doing this, I thought of passing a pointer of the thumbnail image to the view that will be on screen and display it immediately, instead of having to redownload it. However, I am running into a problem - nothing loads when I set the imageView on the new view to the old image. Here is my code:
This is in my UITableView Class:
CustomCell *cell = (CustomCell *)[tableView cellForRowAtIndexPath:indexPath];
NewsViewController *newsViewController = [[NewsViewController alloc] initWithNibName:#"NewsViewController" bundle:nil dictionary: dict type:d numberOfPages:1 image: cell.imageView.image];
NewsViewController.m:
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil dictionary:(NSDictionary *)dict type:(NSInteger)type numberOfPages:(NSInteger)pages image:(UIImage *)image{
self = [super initWithNibName:#"NewsViewController" bundle:Nil];
if (self) {
newsText = [dict objectForKey:#"content"];
newsTitle = [dict objectForKey:#"title"];
newsDate = [dict objectForKey:#"pub_date"];
d = type;
numberOfPages = pages;
imageURL = [[NSMutableArray alloc] initWithCapacity:numberOfPages];
mainImage = [[UIImage alloc] init];
mainImage = image;
}
return self;
}
- (void)viewDidLoad
{
[super viewDidLoad];
labelBody.text= newsText;
titleView.text = newsTitle;
date.text = newsDate;
if (numberOfPages == 1) {
imageScrollView.contentSize = CGSizeMake(320, 303);
pageControl.numberOfPages = 1;
CustomImageView *customImageView = [[CustomImageView alloc] initWithFrame:imageScrollView.bounds];
[imageScrollView addSubview:customImageView];
customImageView.imageView.image = mainImage;
}

I am using mainImage as a (UIImage *) and trying to replace the image in my customImageView class with the main Image but nothing is showing up. What am I missing here?
I guess you'd like to build some sort of caching mechanism for your UIImageView. One of the easiest ways to get all of this working is by making use of the AFNetworking library.
AFNetworking extends UIImageView with some extra methods for loading images from remote sources. AFNetworking has caching build-in, no need to reinvent the wheel :)
Take a look on the following sites:
AFNetworking
UIImageView (AFNetworking)
My app keeps coming up with a "Semantic Error" and keeps freezing/crashing.Everything seems to be stringed together fine and it launches without problem. TextFields work fine but as soon as I click anything else it fails and forces out. Any recommendations?

Be careful about letter cases. field and Field.
And an IBAction without (id)sender doesn't sound good.
Like most of my problems recently, i think it's a syntax problem. I know what i want to do but i don't know how to write it. I am trying to create a Jigsaw-type application. The CGPoints represent the center point of where each image should be.
I have created 40 images and put them into an array.
I want to create 40 CGPoints and put all these points in an array.
The image at images[0] has a corresponding center at cgpoints[0] - or rather this is where the image should be placed in the jigsaw.
I'm having trouble declaring/initializing the array of CGPoints though. Below is the code:

I can't tell if its all a bit of a mess or not. As you can see i've started with only 8 "holders", these are the CGPoints that represent the center of where the jigsaw pieces should be placed.
borrrden is correct. You've created a whole bunch of CGPoint pointer variables by declaring them as properties and synthesizing them. But then in your -viewDidLoad method you're declaring CGPoint structs--not CGPoint pointers--all with the same name as the properties you synthesized.
You don't need the holderN properties at all, to judge from the code. In fact, you don't even need the holderN variables in the -viewDidLoad method. You could easily get away with something like this:
- ( void )viewDidLoad
{
holders = [ NSMutableArray arrayWithObjects:
[ NSValue valueWithCGPoint: CGPointMake(60, 644) ],
...,
[ NSValue valueWithCGPoint: CGPointMake(N, N) ],
nil ];
...
}
Hard-coding the point coordinates is poor design, though. Your best option is to put the coordinates in a plist, which you can load on demand and stuff into an array. This'll mean tweaking the coordinates is just a matter of editing the plist. No recompiling required.
You are getting the message in your comment because you declare variables with the same name as your properties in the beginning of viewDidLoad.
NSPoint is not an object so you have to either use C array: NSPoint points[SIZE] or use NSValue container: [NSValue valueWithCGPoint: point]
