I am facing the following issue,
I have parsed data from a server and I need all keys to be put into the arrays.
(
"shopping|TD|Shopping|TD|customer/shopping_icon.png",
"salon_spa|TD|Salon & Spa|TD|customer/salon_icon.png",
)
These are the keys I'm getting from the server, now I want to put them into an Array.
I have tried using component separated by string but that always crashes the app.
NSMutableArray *allKeysArray =[[NSMutableArray alloc]init];
[allKeysArray addObject: [deals allKeys]];
NSLog(#" all keys --%#",allKeysArray);
NSMutableString *string=[[NSMutableString alloc]init];
string =[allKeysArray objectAtIndex:0];
NSLog(#"string--%#",string);
arr =[string componentsSeparatedByString:#","];
The app crashes saying component separated by string is Terminating app due to uncaught exception
'NSInvalidArgumentException', reason: '-[_]: unrecognized selector
sent to instance 0x75b8dd0'
Replace your code from ....
[allKeysArray addObject: [deals allKeys]];
as like this...
[allKeysArray addObjectsFromArray: [deals allKeys]];
This will solve your problem...

I am parsing JSON data with JSONKit as NSMutableDictionary.
NSString *str = [[NSString alloc] initWithData:self.responseData encoding:NSUTF8StringEncoding];
NSMutableDictionary *jsonResponse = [self.responseData objectFromJSONData];
NSMutableDictionary *newData = [[NSMutableDictionary alloc] init];
[newData addEntriesFromDictionary:[jsonResponse mutableCopy]];
When i do this i am getting this error:
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[NSMutableDictionary addEntriesFromDictionary:]: dictionary argument is not an NSDictionary'
I am trying to figure out what is causing this problem. I know that jsonResponse is an object of JKArray from my other experience.
I need help.
Thanks.
Try the following:
id object = [self.responseData objectFromJSONData];
NSLog(#"%#", [object class]);
Most likely your response is an array instead of a dictionary.
If you really want to convert the array into a dictionary, you could do something like this, using a self-defined key:
NSArray *array = [self.responseData objectFromJSONData];
NSMutableDictionary *dict = [NSMutableDictionary dictionaryWithObject:array forKey:#"posts"];
Though perhaps there are some better options if you could show me the contents of your array.
I'm trying to create multiple placemarks using MKMapItem without using coordinates.
I used location name directly in geocodeAdressString:#"Mumbai"... but I got result for single location.
While I use multiple locations through array, I'm getting this error:
Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[__NSArrayI length]: unrecognized selector sent to instance 0xab48380'
Why is this problem occurring?
Class mapItemClass=[MKMapItem class];
if(mapItemClass &&[mapItemClass respondsToSelector:#selector(openMapsWithItems:launchOptions:)])
{
NSArray *addr=[[NSArray alloc ]initWithObjects:#"Banglore",#"Mumbai",#"Delhi", nil];
CLGeocoder *geocoder=[[CLGeocoder alloc]init];
[geocoder geocodeAddressString:addr completionHandler:^(NSArray *placemarks, NSError *error) {
CLPlacemark *geocodedPlacemark=[placemarks objectAtIndex:0];
MKPlacemark *placemark=[[MKPlacemark alloc]initWithCoordinate:geocodedPlacemark.location.coordinate addressDictionary:geocodedPlacemark.addressDictionary];
MKMapItem *mapItem=[[MKMapItem alloc]initWithPlacemark:placemark];
[mapItem setName:geocodedPlacemark.name];
[MKMapItem openMapsWithItems:#[mapItem] launchOptions:nil];
}];
}
The error state that -[__NSArrayI length]: unrecognized selector sent to instance 0xab48380'
NSArray dont have a property length. So it is unable to find the selector of length. So check where you are using NSArray and keep break points to find where error is happening. length is the method of NSString and NSData but NSArray dont have length, it has count
I have been able to replicate this using this code
id array = [[NSArray alloc] initWithObjects:#"Hello", #"World", nil];
NSLog(#"%d",[array length]);
output
-[__NSArrayI length]: unrecognized selector sent to instance 0x96bafe0
notice how I have used id instead of NSArray with using id I am able to call length which isn't allowed by NSArray, but this gets round the compiler when using id.
So the best way to find out where this is going wrong is add an exception that will catch all exceptions. Do this by selecting the exceptions tab in the project navigator wind >> select '+' >> 'Add Exception Breakpoint...' >> then just select done. This will set a breakpoint every time your app throws an exception.
EDIT
Thanks to the code you have added I suspect that you are passing an NSArray where there should be an NSString. You create
NSArray *addr=[[NSArray alloc ]initWithObjects:#"Banglore",#"Mumbai",#"Delhi", nil];
then pass it to geocodeAddressString:addr
[geocoder geocodeAddressString:addr completionHandler:^(NSArray *placemarks, NSError *error) {
Just from the name of this parameter I suspect it should be an NSString and not an NSArray try replacing addr to [addr objectAtIndex:0] this will get the string object at index 0 of the addr array.
EDIT 2
Here is the method you are calling notice it only allows an NSString to be passed in for geocodeAddressString.
- (void)geocodeAddressString:(NSString *)addressString completionHandler:(CLGeocodeCompletionHandler)completionHandler;
My model class has a NSMutableDictionary with my data. In my view class, I want to display that data in my UITableView cellforRowAtIndexPath method. My view class has an NSArray for the data to display.
I can do this to get my data into my NSArray to display correctly:
self.CategoriesArray = [model.CategoryDictionary allKeys];
However, since NSMutableDictionary does not sort on its own, my items in my TableView are not in alphabetical order. I thought I could do this:
However, I get the following error:
2Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[NSCFBoolean localizedCaseInsensitiveCompare:]: unrecognized selector sent to instance 0x13d0a20'
I'm assuming that's because my view class doesn't know what to do with the localizedCaseInsensitiveCompare method.
How do I solve this problem? Thanks.
I think you were saying that this gives you the correct results, just not in order, right?
self.CategoriesArray = [model.CategoryDictionary allKeys];
If that's the case, then this will give you the correct order if I'm understanding your question correctly:
NSArray* keys = [model.CategoryDictionary allKeys];
self.CategoriesArray = [keys sortedArrayUsingSelector:#selector(localizedCaseInsensitiveCompare:)];
localizedCaseInsensitiveCompare: is only to compare NSString, not NSDictionary or NSArray.
To sort your categoriesArray look at
sortedArrayUsingComparator: and sortedArrayUsingDescriptors: for NSArray
sortUsingDescriptors and sortUsingComparator for NSMutableArray
To loop through your array you can do something like
for (NSString *string in categoriesArray)
{
}
I've got a question: I've got an NSMutableArray, which I pass on in multiple views. In one of the views, a value of an object inside that array (NSMutableDictionary) can be editted. I do that using the code:
NSMutableDictionary *tester = [[NSMutableDictionary alloc] initWithDictionary:selectedItem copyItems:YES];
NSMutableString *newLoc = [[NSMutableString alloc] initWithString:locationField.text];
[tester setValue:newLoc forKey:#"Location"];
[selectedList replaceObjectAtIndex:[selectedList indexOfObject:selectedItem] withObject:tester];
The problem I'm having with this, is replacing that object in selectedList. It gives the error *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[__NSArrayI replaceObjectAtIndex:withObject:]: unrecognized selector sent to instance 0xa631e30'
It works if I copy the new item in a copy-array of selectedList, and alloc selectedList with the new value again, but the other views are having problem finding that same list again in the array (new allocated location).
TL;DR version: how can I edit a value (through replacing?) inside an NSMutableArray? Why doesn't replaceObjectAtIndex work?
EDIT: It was immutable indeed. Still, the main question remains:
I've got:
NSMutableDictionary *tester = [[NSMutableDictionary alloc] initWithDictionary:geselecteerdItem copyItems:YES];
[geselecteerdItem setValue:nieuweLoc forKey:#"Location"];
[geselecteerdeLijst replaceObjectAtIndex:[geselecteerdeLijst indexOfObject:tester] withObject:geselecteerdItem];
When I'm using: [warningList replaceObjectAtIndex:[warningList indexOfObject:geselecteerdeLijst] withObject:keuzeLijst], it gives me an outofbounds error because the index of the array geselecteerdeLijst obviously changed inside warningList. Any idea's?
selectedList is an immutable array, which doesn't support any modifications. You can do something like this, though:
NSMutableArray *tmp = [NSMutableArray arrayWithArray: selectedList];
[tmp replaceObjectAtIndex:[selectedList indexOfObject:selectedItem] withObject:tester];
EDIT: To clarify, __NSArrayI is a concrete immutable subclass of NSArray, __NSArrayM is a mutable one. You should not rely on the private class names, but since they speak for themselves, you can at least know which is mutable and which is not.
i am getting json data from this link
now i want data from "html_instructions": part
NSDictionary *result = [stringtext JSONValue];
NSLog(#"here");
NSArray *resultarr = [result objectForKey:#"routes"];
NSString *string;
for(NSDictionary *di in resultarr){
NSLog(#"for loop");
string = [[di objectForKey:#"legs"] objectForKey:#"steps"];
}
but after printing "for loop" in console it is throwing an exception

please help me
i want html_instructiuons field value
Check if resultarr and di really contains anything or not.
NSDictionary *result = [stringtext JSONValue];
NSLog(#"here");
NSArray *resultarr = [result objectForKey:#"routes"];
CFShow(resultarr);
NSString *string;
for(NSDictionary *di in resultarr){
CFShow(di);
NSLog(#"for loop");
NSArray *tempArr = [[di objectForKey:#"legs"] objectForKey:#"steps"];
}
http://jsonviewer.stack.hu/#http://maps.googleapis.com/maps/api/directions/json?origin=delhi&destination=noida&waypoints=&sensor=true
Check the viewer and set the values accordingly. [di objectForKey:#"legs"] returns an array. the first object of that array is a dictionary which has the key steps. But that too returns another array.
