字符串包含字母 [英] String contains letters

问题描述

我想知道是否有一种方法可以检查字符串是否包含字母.

I'm wondering if there is a way to check if a string is containing a letter.

如果有NSString = @"street 12"，我希望它返回YES 如果NSString = @"12.12,23.23"我希望它返回NO

If there is an NSString = @"street 12" I want it to return YES and if NSString = @"12.12,23.23" I want it to return NO

是否有一种方法可以处理苹果公司制造的产品?还是我必须自己制造?

Is there a method that handles this made by Apple or do I have to make it myself?

推荐答案

这是一种方法:

NSString *someString = ... // the string to check
NSRange match = [someString rangeOfCharacterFromSet:[NSCharacterSet letterCharacterSet] options:0 range:NSMakeRange(0, someString.length)];
if (match.location != NSNotFound) {
    // someString has a letter in it
}
