4.添加属性（方式2）
ClassOne *one = [ClassOne new];
objc_setAssociatedObject(one, "objTag", @"value", OBJC_ASSOCIATION_COPY);
NSString *value = objc_getAssociatedObject(one, "objTag");
NSLog(@"通过Associate设置:%@",value);
5.获取类的名称
ClassOne *one = [ClassOne new];
const char *className = object_getClassName(one);
NSLog(@"className:%@",[NSString stringWithUTF8String:className]);
6.获取一个类的所有方法
UInt count;
Method *methods = class_copyMethodList([ClassOne class], &count);
for (int i = 0; i < count; i++) {
Method method = methods[i];
SEL sel = method_getName(method);
NSLog(@"方法名:%@",NSStringFromSelector(sel));
}
7.获取一个类的所有属性
uint propertyCount;
objc_property_t *ps = class_copyPropertyList([ClassOne class], &propertyCount);
for (uint i = 0; i < propertyCount; i++) {
objc_property_t property = ps[i];
const char *propertyName = property_getName(property);
const char *propertyAttributes = property_getAttributes(property);
NSLog(@"propertyName:%@",[NSString stringWithUTF8String:propertyName]);
NSLog(@"propertyAttributes:%@",[NSString stringWithUTF8String:propertyAttributes]);
}
8.获取类的所有成员变量
uint ivarCount;
Ivar *ivars = class_copyIvarList([ClassOne class], &ivarCount);
for (uint i = 0; i < ivarCount; i++) {
Ivar ivar = ivars[i];
const char *ivarName = ivar_getName(ivar);
NSLog(@"ivarName:%@",[NSString stringWithUTF8String:ivarName]);
}
9.获得成员变量类型
uint ivarCount;
Ivar *ivars = class_copyIvarList([ClassOne class], &ivarCount);
for (uint i = 0; i < ivarCount; i++) {
Ivar ivar = ivars[i];
const char *ivarName = ivar_getName(ivar);
const char *type = ivar_getTypeEncoding(ivar);
NSLog(@"ivarName=%@,type=%@",[NSString stringWithUTF8String:ivarName],[NSString stringWithUTF8String:type]);
}
