if ([scrollView isKindOfClass:[UIView class]]) {
NSLog(@"scrollView is isKindOfClass UIView");
}
if ([scrollView isKindOfClass:[UIScrollView class]]) {
NSLog(@"scrollView is isKindOfClass UIScrollView");
}
if ([scrollView isMemberOfClass:[UIView class]]) {
NSLog(@"scrollView is isMemberOfClass UIView");
}
if ([scrollView isMemberOfClass:[UIScrollView class]]) {
NSLog(@"scrollView isMemberOfClass UIScrollView");
}
输出结果：
scrollView is isKindOfClass UIView
scrollView is isKindOfClass UIScrollView
scrollView isMemberOfClass UIScrollView
结论：
isMemberOfClass 用于判断（实例对象）和（对象的创建类）
isKindOfClass 用于判断（实例对象）和（对象的创建类或继承的类）
