如果我有一个这样创建的数组：

NSArray* arrItems = [[NSArray alloc] initWithObjects:@"One", @"Two", @"Three", nil];

我有一个带有 NSString 属性的类：

myClass.myClassString = @"One";

如果我这样做， isEqualToString 不应该工作：

NSString* strToCheck = myClass.myClassString

for(int i=0; i<arrItems.count; i++) {

    NSString* strThisItem = [arrItems objectAtIndex:i]; 

    if ([strThisItem isEqualToString:strToCheck]) { 
       NSLog(@"Okley dokley!");
    }

}

编辑：

真实世界的结果：

在我的应用程序中，我什至没有得到匹配 - 这是我的日志输出，包含字符串及其长度 - 查看安全营销匹配的位置 - 这里也应该记录一个“OK”。

是的，这应该有效。也许 myClass.myClassString 在 isEqualToString 检查之前没有得到你想要的值。

打印 myClass.myClassString、strToCheck 和 arrItems 的 NSLogs 应该可以帮助您找到问题所在。

现在我看到了你的编辑：

Safety_Marketing_16 <- 两个下划线

安全营销_16 <- 一个下划线

（非常感谢！:D）
