I use this to get the class for a property name:
- (Class)gm_classForPropertyName:(NSString *)propertyName {
objc_property_t prop = class_getProperty([self class], propertyName.UTF8String);
const char * attr = property_getAttributes(prop);
NSString *attributes = [NSString stringWithUTF8String:attr];
NSArray *components = [attributes componentsSeparatedByString:@"\""];
Class propertyClass;
for (NSString *component in components) {
Class class = NSClassFromString(component);
if (class) {
propertyClass = class;
break;
} else {
class = swiftClassMapping[component];
if (class) {
propertyClass = class;
break;
}
}
}
return propertyClass;
}
But this is the important part:
objc_property_t prop = class_getProperty([self class], propertyName.UTF8String);
const char * attr = property_getAttributes(prop);
NSString *attributes = [NSString stringWithUTF8String:attr];
When I log attributes, it still looks like an untyped NSArray as a string. Is there some way to introspect the class type?
T@"NSArray",&,N,V_children
tl;dr
Take this class:
@interface SomeClass : NSObject <GenomeObject>
@property (strong, nonatomic) NSArray<SomeOtherClass *> *children;
@end
Given the class SomeClass, and the property name children is there a way for me to find that children is an array of SomeOtherClass type objects?
