Accessing Property from another NSObjectClass

Question

I am using 2 nsobject class ,

First nsobject class some property and it holds some values. In Second NSObject class i want to access the first nsobject class properties. I have tried little bit ,it showing null values Here is my code My First NSObject class FieldData.M

-(instancetype)initWithDictionary:(NSDictionary *)dictFieldData
{
if (self = [super init]) {

    ///set the field id
    self.fieldId = [[dictFieldData objectForKey:@"f_id"]intValue];
    self.display = [[dictFieldData objectForKey:@"f_display"]boolValue];
    self.fieldLength = [[dictFieldData objectForKey:@"f_length"]intValue];
    self.mandatory = [[dictFieldData objectForKey:@"f_mandatary"]boolValue];
    self.strFieldLabel = [dictFieldData objectForKey:@"f_label"];

    NSString *strFieldAttrib = [dictFieldData objectForKey:@"f_attribute"];
    if ([strFieldAttrib.lowercaseString isEqualToString:@"alpha"]) {

        self.fieldAttribute = FieldAttributeAlpha;
    }
    else if ([strFieldAttrib.lowercaseString isEqualToString:@"numeric"]) {

        self.fieldAttribute = FieldAttributeNumeric;
    }
    else if ([strFieldAttrib.lowercaseString isEqualToString:@"alpha_numeric"]) {

        self.fieldAttribute = FieldAttributeAlphaNumeric;
    }

    }return self;
    }

****Second NSObjectClass** SiteData.m**

-(instancetype)initWithDictionary:(NSDictionary *)dictSiteData
{

self.fieldData = [FieldData new];

if (self = [super init]) {


    self.siteId = [[dictSiteData objectForKey:@"s_id"]intValue];

    self.siteName = [dictSiteData objectForKey:@"site_name"];

    NSLog(@"%d",self.fieldData.fieldId);





}

return self;
}

[FieldData new] will by default invoke the init method, not the initWithDictionary one. Unless you've defined init to set values for your property it will default to nil. You probably need to create your object using [[FieldData alloc] initWithDictionary:...] (or [FieldData newWithDictionary:...] if you've defined that method). HTH

@AgalSivamanoj - Edit your question and show the interface for `FieldData`, all it's `init` and `new` members, and the revised `SiteData` code which creates the `FieldData` instance. – CRD Oct 24 '16 at 07:34

Please write this code in Appdelegate declare this property. After that SetValue your Dictionary Data

@property(strong,nonatomic)NSDictionary * dictFieldData;

Write this code My First NSObject class FieldData.M Create object in ViewdidLoad

 AppDelegate *appdelegate ((AppDelegate *)[[UIApplication sharedApplication] delegate]);


///set the field id
self.fieldId = [[appdelegate.dictFieldData SetValue:(NSString*) objectForKey:@"f_id"]intValue];

///Get the field id
self.siteId = [[appdelegate.dictSiteData Valueforkey:@"s_id"]intValue];

NSLog(@"%d",appdelegate.dictSiteData);
