I am trying to remove every instance of an RLMObject subclass and whenever I call [Realm defaultRealm] my app crashes. Here is what I keep getting in the console. I am using cocoapods, version 0.93.2
*** Terminating app due to uncaught exception 'RLMException', reason: 'Can't persist property 'Id' with incompatible type. Add to ignoredPropertyNames: method to ignore.'

Here is the RLMObject subclass:
#import "RLMObject.h"
#interface CGCUser : RLMObject
#property NSString *EmailAddress;
#property BOOL IsActive;
#end
And a second object
#interface CGCCardInfo : RLMObject
#property NSInteger *Id;
#property NSString *nickName;
#property NSString *token;
#property NSString *displayNumber;
#property BOOL *isDefault;
#property NSString *cardType;
#end
RLM_ARRAY_TYPE(CGCCardInfo)
The issue there is the line #property BOOL *isDefault;
If you change that to #property BOOL isDefault; it should do exactly what you want!
The same happened to me.
#property NSInteger *Id is the problematic field over here. You use a pointer to NSInteger instead of NSInteger itself.
The solution is to replace it with a direct reference: #property NSInteger Id

I press on CONTROL and drag the UIImageVIew and UILabel which is in AppView.xib to my code file named "AppVIew.h". Before I connect the two UI widgets it ran ok ,I want to know the reasons leading to the crash.Very thanks for your answers.
#property
The code as following:
#import <UIKit/UIKit.h>
#interface AppView : UIView
#property (weak, nonatomic) IBOutlet UIImageView *icon;
#property (weak, nonatomic) IBOutlet UILabel *name;
+ (id)AppViewWithIcon:(NSString *)icon Name:(NSString *)name;
#end
#import "AppView.h"
#implementation AppView
+ (id)AppViewWithIcon:(NSString *)icon Name:(NSString *)name{
AppView *view = [[NSBundle mainBundle] loadNibNamed:#"AppView" owner:nil options:nil][0];
NSLog(#"%#",view);
return view;
}
the errors as following:

Check if their are any previous outlets that have been deleted from within the storyboard, by either checking the view controller inspector and referencing outlets for any outlets that may contradict the ones you have made as well as the UIView/UILabel.
RJobObject * jobObj = [RJobObject new];
RKMappingOperation *mappingOperation = [[RKMappingOperation alloc] initWithSourceObject:jobDictionary destinationObject:jobObj mapping:[RJobObject mapping]];
mappingOperation.dataSource = (id)jobObj;
[mappingOperation start];
jobDictionary structure:
NSDictionary *msg1 = #{
#"id" : #"dfcd",
#"message" : #"ndjfcdfcd"
};
NSDictionary *msg2 = #{
#"id" : #"fjvdfv",
#"message" : #"kjndcdovc"
};
NSDictionary *msg3 = #{
#"id" : #"fce",
#"message" : #"dfcdf"
};
NSArray *msgsArray = [NSArray arrayWithObjects:msg1, msg2,msg3, nil];
NSMutableDictionary * jobDictionary = [NSMutableDictionary dictionaryWithDictionary:#{#"id" : #"Sourabh pant",
#"title": #"http://www.google.com"
}];
[jobDictionary setObject:msgsArray forKey:#"messages"];
/......................................................./
RJobObject is the custom object:
#property (nonatomic) NSString * id;
#property (nonatomic) long long duration;
#property (nonatomic) NSString * title;
#property (nonatomic) NSString * image;
#property (nonatomic) NSString * secret;
#property (nonatomic) NSInteger unreadCount;
#property (nonatomic) NSArray * messages;
This creates a crash inside RRestkit, if the jobDictionary contains messages.If the messages array inside jobDictionary is empty,then the code runs fine.
So to sum up the message array is not being mapped.

This line is incorrect:
mappingOperation.dataSource = (id)jobObj;
because you are giving the operation a plain data model object as a data source (and telling the compiler to like it by casting to id).
When the operation runs it needs some new instances to be created so it can map the content from the JSON dict into them, this is a job the data source is supposed to do. When the operation asks the data source you get a crash because the object you provided as the data source, jobObj, doesn't understand the request.
You need to create and set an appropriate data source that can handle this requirement.
I have followed all the steps mentioned in Facebook IOS SDK Docs.
My ViewController.h file is as below
#import <UIKit/UIKit.h>
#import <FacebookSDK/FacebookSDK.h>
#interface ViewController : UIViewController <FBLoginViewDelegate>
#end
My ViewController.m file is as below
#import "AppDelegate.h"
#import "ViewController.h"
#import "pageLike.h"
#interface ViewController ()
#property (weak, nonatomic) IBOutlet FBLoginView *fbloginbtn;
#property (weak, nonatomic) IBOutlet UILabel *name;
#property (weak, nonatomic) IBOutlet FBProfilePictureView *fbimage;
#property (weak, nonatomic) IBOutlet UILabel *status;
#end
#implementation ViewController

[super viewDidLoad];
self.fbloginbtn.readPermissions = #[#"public_profile",#"email",#"user_friends"];
self.fbloginbtn.publishPermissions = #[#"publish_actions"];
self.fbloginbtn.delegate =self;
// Do any additional setup after loading the view, typically from a nib.
if(FBSessionStateOpen){
pageLike *pg=[self.storyboard instantiateViewControllerWithIdentifier:#"pageLike"];

I have created another view controller named pageLike where i need to actually navigate once user is logged in
Check the pageLike controller and remove all the fb login view controller as they might be creating issues .
I called method in another class (they are both singletons).
WebserviceHelper.h
#interface WebserviceHelper : NSObject {
int currentType;
NSString *SERVER_URL;
WebserviceManager *webService;
}
#property (nonatomic, assign) id delegate;
- (void)retrieveStudentwithCode:(NSString *)code {
currentType = STUDENT_TYPE;
NSString *param = [NSString stringWithFormat:#"token=uencom&cid=%#", code];
NSString *link = [NSString stringWithFormat:#"%#getStudentInfo", SERVER_URL];
[webService retrieveData:link withParameters:param];
}
After call webservice and get data it cached here in received data. I check and it works fine
but when it deliver to didFinishLoading error happen here
- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)receivedData {
data = [NSMutableData new];
[data appendData:receivedData];
}
- (void)connectionDidFinishLoading:(NSURLConnection *)connection {
[self stopPostingToWebservice];
//it carsh here
[delegate: data];
}

Try this, have a protocol declaration in WebserviceHelper.h like
#protocol studentDataDelegate <NSObject>
-(void)WebserviceHelper:(WebserviceHelper *)webserviceHelper didStudentDataDownloadCompleteWithData:(NSMutableData *)data;
#end
WebserviceHelper.m
- (void)connectionDidFinishLoading:(NSURLConnection *)connection {
[self stopPostingToWebservice];
[self.delegate WebserviceHelper:self didStudentDataDownloadCompleteWithData:data];
}
so which ever class confirms to the above protocol should implement the delegate method like,
#interface RequestingDataClass : UIViewController <studentDataDelegate>
by doing this you will receive the warning that you have not implemented didStudentDataDownloadCompleteWithData:method so do it like
-(void)WebserviceHelper:(WebserviceHelper *)webserviceHelper didStudentDataDownloadCompleteWithData:(NSMutableData *)data;
{
webserviceHelper.delegate=self;
// Do something with the `data`
}
You do no show the declaration of the delegate, however this statement:
[delegate: data];
Should be:
[delegate haveSomeData:data];
(or something similar)
did you create protocol in your WebserviceHelper.h file like this?
#protocol WebserviceHelperDelegate <NSObject>
#required
-(void)reciveData:(NSData *)data;//or your method
#end
decleare a property
#property (nonatomic,strong) id <WebserviceHelperDelegate> delegate;
then call this method like
- (void)connectionDidFinishLoading:(NSURLConnection *)connection {
[self stopPostingToWebservice];
//it carsh here
[self.delegate reciveData: data];
}
And implement this method from where you call webservice class and assign delegate
-(void)reciveData:(NSData *)data{
}
I have a nasty bug and I would appreciate any guidance pointing me in the general direction of a solution. Occasionally, I get the following exception which pertains to calling initWithCoder on 3 different NSManagedObject subclasses in my core data model. If I delete the app from my device and reload it, or reset content on the simulator the exception goes away. No where in my code do I explicitly call initWithCoder on an NSManagedObject Subclass.
The bug seems to arise randomly after editing random parts of my source code. Any ideas on where to begin?

Here is the method that is called before things go wrong:
-(NSInteger)sumTheValuesInSet:(NSMutableSet *)set withAttributeKeyForValue:(NSString *)attributeKey
{
NSInteger sumToReturn = 0;
for (id obj in set) {
sumToReturn = sumToReturn +[[obj valueForKey:attributeKey] integerValue];
}
return sumToReturn;
}
The method enumerates through Cost objects in the NSSet [sellingCosts valueForKey:#"moreCosts"].
Here is the model for the Cost object//
// Cost.h
// Flip Evaluator and Manager
//
#import <Foundation/Foundation.h>
#import <CoreData/CoreData.h>
#class BuyingCosts, HoldingCosts, SellingCosts, OtherCosts, TotalCosts;
#interface Cost : NSManagedObject
#property (nonatomic, strong) BuyingCosts *buyingCosts;
#property (nonatomic, strong) HoldingCosts *holdingCosts;
#property (nonatomic, strong) SellingCosts *sellingCosts;
#property (nonatomic, strong) OtherCosts *otherCosts;
#property (nonatomic, strong) NSString * name;
#property (nonatomic, strong) TotalCosts *incompleteCosts;
#property (nonatomic, strong) TotalCosts *completedCosts;
#property (nonatomic, strong) NSNumber *complete;
#property (nonatomic, strong) id costType;
#property (nonatomic, strong) NSNumber *amount;
#end
Share your model as well as this appears to be a transform problem at first glance.
You should also share the code in -sumTheValuesInSet:withAttributeKeyForValue: as that seems to be the last point in your code before things go wrong.
