1.去掉字符串两端的空格及回车

- (NSString *)removeSpaceAndNewline:(NSString *)str{

    NSString *temp = [str stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceCharacterSet]];


    NSString *text = [temp stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet ]];

    return text;
}

2.去掉所有的空格及字符串

- (NSString *)removeSpaceAndNewline:(NSString *)str{

    NSString *temp = [str stringByReplacingOccurrencesOfString:@" " withString:@""];
    temp = [temp stringByReplacingOccurrencesOfString:@"\r" withString:@""];
    temp = [temp stringByReplacingOccurrencesOfString:@"\n" withString:@""];
    return temp;
}
