Question

I’ve got an array populated with json.

rows4 = [dict objectForKey:@"users"];

I have the following line that parses a key value from it.

NSString *hotelname = (NSString *) [rows4 valueForKey:@"H_NAME"];

I then assign the value to a label in the view with the following line:

LabelName.Text= hotelname;

Everything seems fine upto here. I write the log with Nslog as follows :

NSLog(@"HotelName : %@",hotelname);

This comes up in log:

[11437:f803] HotelName : (
“Blah Blah Hotel”
)

And then the simulator crashes with the following error in log:

NSArrayI isEqualToString:]: unrecognized selector sent to instance

What I understand from this is the variable that I assign to the label is actually not a variable but it is an array. Am I right? If so, how can I extract a single value from my variable with the help of a key and assign it to a variable which then I can assign to a label?

I am using touchJSON btw.

One option would be:

if(hotelname.count > 0)    
    LabelName.Text= [hotelname objectAtIndex:0];
