objective-c - 如何使用 NSString 检测字符串是否在字符串中

Question

假设我有一个字符串“Test Super”

我将如何检测“超级”并让函数返回“是”？

Answer 1

像这样的东西：

return (([@"Test Super" rangeOfString:@"Super"]).location != NSNotFound);

Answer 2

使用rangeOfString:并检查结果的位置是否等于NSNotFound.

[@"Test Super" rangeOfString:@"Super"].location != NSNotFound //YES
[@"Test Super" rangeOfString:@"Supper"].location != NSNotFound //NO

Answer 3

一个快速的谷歌发现这个： http: //objcolumnist.com/2009/04/12/does-a-nsstring-contain-a-substring/

NSRange 文本范围；textRange =[字符串 rangeOfString:substring];

if(textRange.location != NSNotFound)
{

//Does contain the substring
}
