iOS determines if a type is from the system nsfoundation

Idea: Record the types in all nsfoundation into an array, and then pass the array's

Containsobject: Method to determine whether the type to be judged is contained in this array.

The simple code is as follows:

+ (BOOL) Isclassfromfoundation: (Class) C {

nsarray* foundationclasses = @[@ "NSObject", @ "NSNumber", @ "Nsarray", @ "Nsmutablearray", @ "NSData", @ "Nsmutabledata", @ " NSDate ", @" Nsdictionary ", @" Nsmutabledictionary ", @" NSString ", @" nsmutablestring "];

Determine if C is in the foundationclasses array

return [foundationclasses CONTAINSOBJECT:C];

}
