    <p>I´m trying to to add many Annotations (depends on how many objects a have in my Array) to my Mapview like this:</p> <pre><code>-(void)viewWillAppear:(BOOL)animated { [mapView removeAnnotations:mapView.annotations]; for (Daten *info in datenArray) { CLLocationCoordinate2D location; location.latitude = (double)[info.lati doubleValue]; location.longitude = (double)[info.longi doubleValue]; MapPin *newAnnotation =[[[MapPin alloc] initWithTitle:info.rating andCoordinate:location] autorelease]; [mapView addAnnotation:newAnnotation]; } [self zoomToFitMapAnnotations:self.mapView]; [self.mapView selectAnnotation:self.mapView.annotations.lastObject animated:YES]; </code></pre> <p>}</p> <p>The first time I switch to that View it works perfectly...But if i come a second time to this View, i get this Bad Access with Error:</p> <pre><code>*** -[CFString length]: message sent to deallocated instance 0x17e140c0 </code></pre> <p>Edit:</p> <p>Thats my MapPin Class:</p> <pre><code>@interface MapPin : NSObject &lt;MKAnnotation&gt; { NSString *title; NSString *subtitle; CLLocationCoordinate2D coordinate; } @property (nonatomic, copy) NSString *title; @property (nonatomic, readonly) CLLocationCoordinate2D coordinate; @property (nonatomic, readonly, copy) NSString *subtitle; - (id)initWithTitle:(NSString *)ttl andCoordinate:(CLLocationCoordinate2D)c2d; </code></pre> <p>EDIT2:</p> <p><img src="https://i.stack.imgur.com/M5ppc.png" alt="Exception"></p> <p>Edit3:</p> <p>Here´s the implementation:</p> <pre><code>#import "MapPin.h" @implementation MapPin @synthesize title, coordinate, subtitle; - (id)initWithTitle:(NSString *)ttl andCoordinate:(CLLocationCoordinate2D)c2d { [super init]; subtitle = ttl; title = @"Rating:"; coordinate = c2d; return self; } - (void)dealloc { [title release]; [subtitle release]; [super dealloc]; } @end </code></pre>

    1. COwhere do you use strings? Can you add more code? On which line your app crashes?

    2. COYou are sending a wrong parameter somewhere :) I had a similar issue. You are sending a NSString where something else is expected (Like a class type or something).

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
