NSPredicate检查对象类的种类

Question

我有一个UIView对象数组.我想调用- (NSArray *)filteredArrayUsingPredicate:(NSPredicate *)predicate这个数组来获取MyCustomView对象数组.

如何用"isKindOf:"编码谓词？

Answer 1

尝试(贬低)

[NSPredicate predicateWithFormat: @"className == %@", [someObject className]]

要么

[NSPredicate predicateWithFormat: @"class == %@", [someObject class]]

Answer 2

我使用Jef的方法得到了错误.不过,这对我有用.

NSPredicate *predicate = [NSPredicate predicateWithFormat:
                                              @"self isKindOfClass: %@", class];
