如何将UITextfield输入与不同的字符串进行比较? [英] How do I compare UITextfield input to different strings?

问题描述

我想将UITextfield的输入值与其他一些字符串进行比较.这是我的猜测.

I want to compare the value of the input from a UITextfield to some other strings. Here's my guessing.

if ([textfield.text isEqualToString:@"First" || @"Second" || @"Third"]) {
    // do something
}

有什么更好的方法吗?

推荐答案

在有一系列对象(例如您的示例)的情况下，应将其添加到数组中并测试其在数组中的存在:

In a situation where you have a series of objects such as your example, you would add then to an array and test its existence in the array:

示例

NSMutableArray *arr = [[[NSMutableArray alloc] init] autorelease];
[arr addObject:@"First"];
[arr addObject:@"Second"];
[arr addObject:@"Third"];

if ([arr containsObject:textField.text])
{
    // do something
}
