    copied!<p>I'm quite new to Objective-C. I've been trying to fetch from my core data entity. The following code fetches the right row because it only returns 1 result. but when I try to <code>NSlog()</code> it to see its values what I get is:</p> <pre><code>iGym[3922:c07] ( "&lt;User: 0x8397690&gt; (entity: User; id: 0x8341580 &lt;x-coredata://114815EF-85F4-411F-925B-8479E1A94770/User/p19&gt; ; data: &lt;fault&gt;)" ) </code></pre> <p>I am used to PHP that I just do a <code>var_dump()</code> and i get all the information in the array... specially when I am expecting 16 results as this entity has 16 fields.</p> <p>Could anyone tell me how could I inspect that array? and also, most important, how do I ultimately do this: fetch the <code>Gender</code> field of the matched <code>email</code> field and assign it to a <code>NSString</code> variable.</p> <p>The query i want to do in sql is <code>SELECT Gender FROM myTable WHERE email = "something@something.com;</code></p> <pre><code>-(NSInteger*)selectedGenderMethod { NSEntityDescription *entityDesc = [NSEntityDescription entityForName:@"User" inManagedObjectContext:context]; NSFetchRequest *request = [[NSFetchRequest alloc] init]; [request setEntity:entityDesc]; request.predicate = [NSPredicate predicateWithFormat:@"email = %@",_currentUser]; NSError *error = nil; NSArray *matches = [[context executeFetchRequest:request error:&amp;error] mutableCopy]; NSString * someVar= [matches[0] objectForKey:@"email"]; NSLog(@"%@",someVar); //More to come once this is sorted return 0; } </code></pre> <p>This fetching code is happening in my <code>genderPickerViewController : UIViewController</code></p> <pre><code>NSLog(@"%@", matches[0]); </code></pre> <p>returns</p> <pre><code>&lt;User: 0x83a6b00&gt; (entity: User; id: 0x83995f0 &lt;x-coredata://114815EF-85F4-411F-925B-8479E1A94770/User/p19&gt; ; data: &lt;fault&gt;) </code></pre> <p>This is my <code>User.h</code>:</p> <pre><code>#import &lt;Foundation/Foundation.h&gt; #import &lt;CoreData/CoreData.h&gt; @interface User : NSManagedObject @property (nonatomic, retain) NSDate * dob; @property (nonatomic, retain) NSString * email; @property (nonatomic, retain) NSNumber * firstTime; @property (nonatomic, retain) NSString * gender; @property (nonatomic, retain) NSString * height; @property (nonatomic, retain) NSNumber * idFB; @property (nonatomic, retain) NSNumber * idUserExternal; @property (nonatomic, retain) NSNumber * idUserInternal; @property (nonatomic, retain) NSNumber * isPT; @property (nonatomic, retain) NSString * language; @property (nonatomic, retain) NSString * metricSystem; @property (nonatomic, retain) NSString * name; @property (nonatomic, retain) NSString * nickname; @property (nonatomic, retain) NSString * password; @property (nonatomic, retain) NSString * surname; @property (nonatomic, retain) NSString * weight; @end </code></pre> <p><code>User.m</code>:</p> <pre><code>@implementation User @dynamic dob; @dynamic email; @dynamic firstTime; @dynamic gender; @dynamic height; @dynamic idFB; @dynamic idUserExternal; @dynamic idUserInternal; @dynamic isPT; @dynamic language; @dynamic metricSystem; @dynamic name; @dynamic nickname; @dynamic password; @dynamic surname; @dynamic weight; @end </code></pre>
