- (NSString *)noWhiteSpaceString {

NSString *newString = self;

// newString = [newString stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]]; //去除掉首尾的空白字符和换行字符

newString = [newString stringByReplacingOccurrencesOfString:@"\r" withString:@""];

newString = [newString stringByReplacingOccurrencesOfString:@"\n" withString:@""];

newString = [newString stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]]; //去除掉首尾的空白字符和换行字符使用

newString = [newString stringByReplacingOccurrencesOfString:@" " withString:@""];

// 可以去掉空格，注意此时生成的strUrl是autorelease属性的，所以不必对strUrl进行release操作！

// newString = [newString stringByReplacingOccurrencesOfString:@"\n" withString:@""];

return newString;
