说我有课
@interface Person : NSObject { NSString *name; }
我需要获取类中 NSString 的名称
Person *person = [[Person alloc] init];
NSLog(@"Name of variable %s\n", _NameofVariable_(person->name));
感谢您的回答，这是我根据回复得出的解决方案
//returns nil if property is not found
-(NSString *)propertyName:(id)property {
unsigned int numIvars = 0;
NSString *key=nil;
Ivar * ivars = class_copyIvarList([self class], &numIvars);
for(int i = 0; i < numIvars; i++) {
Ivar thisIvar = ivars[i];
if ((object_getIvar(self, thisIvar) == property)) {
key = [NSString stringWithUTF8String:ivar_getName(thisIvar)];
break;
}
}
free(ivars);
return key;
}
一样容易
#define VariableName(arg) (@""#arg)
然后你就可以：
NSObject *obj;
NSString *str = VariableName(obj);
NSLog(@"STR %@", str);//obj
