NSStringFromClass([instance class]) should do the trick.

NSStringFromClass([实例类])应该执行这个技巧。

#2

if all you want to do is test an object to see if it's a type of a certain Class

如果您只想测试一个对象，看看它是否是某个类的类型

BOOL test = [self isKindOfClass:[SomeClass class]];

#3

From within the class itself

来自类本身

-(NSString *) className
{
    return NSStringFromClass([self class]);
}

#4

Just add a category:

只是增加一个类别:

NSObject+Extensions.h
- (NSString *)className;

NSObject+Extensions.m
- (NSString *)className {
    return NSStringFromClass(self.class);
}

Then use the following code:

然后使用以下代码:

NSString *className = [[SomeObject new] className];

or even:

甚至:

NSString *className = SomeObject.new.className;

To use it anywhere add the category to YourProject.pch file.

要在任何地方使用它，请将类别添加到项目中。pch文件。

If you are looking how get classname in Swift you can use reflect to get information about object.

如果您正在查看如何在Swift中获取类名，您可以使用反射来获取有关对象的信息。

let tokens = split(reflect(self).summary, { $0 == "." })
if let typeName = tokens.last {
    println(typeName)
}
