Objective-C how to check if a string is null
- by norskben
SO
I wish to check to see if the item in my array [clientDataArray objectForKey:@"ClientCompany"] is nil.
temp = [clientDataArray objectForKey:@"ClientCompany"];
if (temp != [NSNull null]) infofieldCompany.text = temp;
So far I have been able to achieve this through the above code, but it does give me the warnings
warning: 'NSArray' may not respond to'-objectForKey:'
warning: comparison of distinct
Objective-C types 'struct NSNull *'
and 'struct NSString *' lacks a cast
My main interest is the second warning, but the first warning also interest me.
How should I adapt my above code?
