objective-c - 删除斜线之前的字符串，Objective C

Question

我需要字符串中正则表达式的帮助:

/folder1/folder2/folder3/folder4/folder5/folder6/folder7/ololo/ImageName.png

我需要匹配:

ololo/ImageName.png

在 Objective-C 中如何做到这一点？

Answer 1

匹配字符串。

NSPredicate *predicate = nil;
predicate = [NSPredicate predicateWithFormat:@"SELF MATCHES 'ololo/ImageName.png'"];
if (![predicate evaluateWithObject:@"/folder1/folder2/folder3/folder4/folder5/folder6/folder7/ololo/ImageName.png"]) 
{
// do your work here.. 
}
