This is my code for getting postal code.
CLGeocoder *reverseGeocoder = [[CLGeocoder alloc] init];
[reverseGeocoder reverseGeocodeLocation:locationManager.location completionHandler:^(NSArray *placemarks, NSError *error)
{
NSLog(#"reverseGeocodeLocation:completionHandler: Completion Handler called!");
if (error){
NSLog(#"Geocode failed with error: %#", error);
return;
}
NSLog(#"Received placemarks: %#", placemarks);
CLPlacemark *myPlacemark = [placemarks objectAtIndex:0];
NSString *countryCode = myPlacemark.ISOcountryCode;
NSString *countryName = myPlacemark.country;
NSLog(#"My country code: %# and countryName: %#", countryCode, countryName);
}];
But its always crashing with NSInvalidArgumentException error,
2017-02-07 12:29:58.124 CBB[3654:270750] Lat : 42.771389 Long :

bytes is NSData's property, so you use NSDictionary as NSData.

[self.arrEmail removeAllObjects];
self.arrEmail = [[NSMutableArray alloc]init];
for (NSDictionary *object in [dictionary valueForKey:#"heroes"]) {
NSString *objectName = object[#"user_email"];
[self.arrEmail addObject:objectName];

My application is crashing at these lines of code. Xcode says
[__NSArrayI objectForKeyedSubscript:]: unrecognized selector sent to instance.
Can any one help?
This seems like it should be pretty straight forward - but alas, I'm getting a crash. I'm simply trying to set my UILabel with the text returned from the users_name field:
.m
NSMutableDictionary *viewParams = [NSMutableDictionary new];
[viewParams setValue:#"u000" forKey:#"view_name"];
[DIOSView viewGet:viewParams success:^(AFHTTPRequestOperation *operation, id responseObject) {
self.userData = [responseObject mutableCopy];
self.username.text = [self.userData objectForKey:#"users_name"];
dispatch_async(dispatch_get_main_queue(), ^(void){
});
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Failure: %#", [error localizedDescription]);
}];
The console data returns:
2016-04-05 12:25:36.877 [1331:350069] This is the Other User Data (
{
address = "Vancouver";
userbio = "There is currently no bio available for this user. If you have added your bio, and require assistance, please contact the Team.";
"users_name" = Brittany;
},
That said, this line is causing the crash:
self.username.text = [self.userData objectForKey:#"users_name"];
And this is the error:

How might I fix this? It seems like it should be simple...
I suppose userData is an Array type. Array have no key values.
Try: [[self.userData objectAtIndex:0] objectForKey:#"users_name"];
I am trying to access keys from a multi NSDictionary.
This is my output from NSLog
Berlijn[23667:60b] data = {
1 = {
data = (
4,
0,
0,
0
);
key = "June 2014";
};
}
When I try to loop through this dictionary and log the key I get NSInvalidArgumentException because key is a NSString.
This is my current code:
- (void) updateRating: (int) companyID {
APICaller *api = [[APICaller alloc] init];
[api setUrl:#"http://domain.examle/api/getcompanyhistory.php"];
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
NSDictionary *parameters = #{
#"token": [[[FBSession activeSession] accessTokenData] accessToken],
#"device_token" : [defaults stringForKey:#"uniqueToken"],
#"companyid" : #(companyID)
};
[api setParameters: parameters];
[api sendPostRequest: ^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(#"data = %#", responseObject);
for(NSDictionary *contentData in responseObject) {
NSLog(#"contentData = %#", [contentData objectForKey:#"key"]);
}
[self.tableView reloadData];
}: ^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Error: %#", error);
}];
}
As NSDictionary is a dictionary I don't know why it returns a string.

Just because you call contentData a dictionary does NOT make it one.
Fast enumeration of a dictionary iterates over keys, NOT values. Your key is a string (even though you call it an NSDictionary) and will throw an exception when you try to call objectForKey: on it.
Since responseObject is a dictionary you can iterate over the keys AND values using enumerateKeysAndObjectsUsingBlock:(void (^)(id key, id obj, BOOL *stop)).
Another option is to use fast enumeration correctly like so...
for(NSString *key in responseObject) {
NSLog(#"contentData = %#", [responseObject objectForKey:key]);
}
In my iOS app I'm trying to update user information in the database (with Stackmob), but I keep getting "unrecognized selector sent to instance."
- (IBAction)save:(UIButton *)sender {
NSFetchRequest *fetchRequest = [[NSFetchRequest alloc] initWithEntityName:#"User"];
NSPredicate *predicte = [NSPredicate predicateWithFormat:#"username == %#", self.username];
[fetchRequest setPredicate:predicte];
[self.managedObjectContext executeFetchRequest:fetchRequest onSuccess:^(NSArray *results) {
NSManagedObject *todoObject = [results objectAtIndex:0];
[todoObject setValue:#"example#gmail.com" forKey:#"email"];
[self.managedObjectContext saveOnSuccess:^{
NSLog(#"You updated the todo object!");
} onFailure:^(NSError *error) {
NSLog(#"There was an error! %#", error);
}];
} onFailure:^(NSError *error) {
NSLog(#"Error fetching: %#", error);
}];
}
Here's the full error I'm getting:
-[NSNull length]: unrecognized selector sent to instance 0x1ec5678
2013-07-21 12:01:25.773 [29207:c07] *** Terminating app due to uncaught exception 'NSInvalidArgumentException',

Thanks in advance.
I think it may because your self.username is empty. Note that if you are getting the username data from json , you can't use
if(username){...} but
if(![username isKindOfClass:[NSNull class]])
to avoid empty data because the json interpreter will generate an NSNull object.
I'm trying to replace a string with another one by using stringByReplacingOccurrencesOfString, but for some reason it's giving me this error:
-[__NSCFNumber length]: unrecognized selector sent to instance 0x6e49ef0
2012-05-14 16:30:49.741 coop[78129:f803] * Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[__NSCFNumber length]: unrecognized selector sent to instance 0x6e49ef0'
NSString *_currentGroup;
NSString *location = [current objectForKey:#"location"];
if(_currentGroup != nil)
{
NSLog(#"_currentGroup: %#", _currentGroup);
// OUTPUT: _currentGroup: 92
location = [location stringByReplacingOccurrencesOfString:#"%group_id%" withString:_currentGroup];
}
When I try the following it just works
location = [location stringByReplacingOccurrencesOfString:#"%group_id%" withString:#"anyOtherString"];
Am I still missing something?
Your "NSString" is actually an NSNumber. That's what the error is telling you.
