//過濾空格
NSString * urlStr = @"  A as    dd  dmm ";
NSLog(@"urlStr = %@",urlStr);

//過濾字串前後的空格
urlStr = [urlStr stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceCharacterSet]];
NSLog(@"urlStr = %@",urlStr);

//過濾中間空格
urlStr = [urlStr stringByReplacingOccurrencesOfString:@" " withString:@""];
NSLog(@"urlStr = %@",urlStr);
