我想比较没有任何标点符号、空格、重音等的名字。 目前我正在做以下操作:
-(NSString*) prepareString:(NSString*)a {
//remove any accents and punctuation;
a=[[[NSString alloc] initWithData:[a dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES] encoding:NSASCIIStringEncoding] autorelease];
a=[a stringByReplacingOccurrencesOfString:@" " withString:@""];
a=[a stringByReplacingOccurrencesOfString:@"'" withString:@""];
a=[a stringByReplacingOccurrencesOfString:@"`" withString:@""];
a=[a stringByReplacingOccurrencesOfString:@"-" withString:@""];
a=[a stringByReplacingOccurrencesOfString:@"_" withString:@""];
a=[a lowercaseString];
return a;
}
不过,我需要对数百个字符串执行此操作,并且我需要使其更加高效。有什么想法吗?
