我正在try 判断要用作URL的字符串是否以http开头.我现在试着判断的方式似乎不管用.以下是我的代码:
NSMutableString *temp = [[NSMutableString alloc] initWithString:@"http://"];
if ([businessWebsite rangeOfString:@"http"].location == NSNotFound){
NSString *temp2 = [[NSString alloc] init];
temp2 = businessWebsite;
[temp appendString:temp2];
businessWebsite = temp2;
NSLog(@"Updated BusinessWebsite is: %@", businessWebsite);
}
[web setBusinessWebsiteUrl:businessWebsite];
有什么主意吗？
