我写了一些代码来获取我想要的格式字符串，我得到了EXC_BAD_ACCESS（代码= 2地址= 0x100）。
这里是代码：
NSString *inCook = [NSString stringWithFormat:@"GETAFREE_AUTH_HASH=%@; GETAFREE_USER_ID=%@", FRLAuthHash, FRLUserID];
NSLog(@"%@",inCook);
NSString *cookie1 = [[NSString alloc]init];
cookie1 = [NSString stringWithFormat:@"__utma=138759908.342110698.1339513728.1347619146.1347628547.51; __utmz=138759908.1339513728.1.1.utmcsr=google|utmccn=(organic)|utmcmd=organic|utmctr=(not%20provided); __atuvc=0%7C33%2C0%7C34%2C0%7C35%2C16%7C36%2C50%7C37; GETAFREE_REFERRAL_URL=https%3A%2F%2Fwww.freelancer.com%2Fusers%2Fonlogin.php; _chartbeat2=skcgjvrzgugx7kr0.1339513733066.1347628548930.00000000000001; WRUID=0; session2=6d909115a69f37ff641d798045d6f252; __qca=P0-624434954-1344332147605; FL_DASHBOARD_VIEWPAGE_4164248=sellerview; FL_DASHBOARD_TABINDEX_4164248=6; GETAFREE_LANGUAGE=en; __utmc=138759908; __utmb=138759908.1.10.1347628547; SpryMedia_DataTables_project_table_=%7B%22iCreate%22%3A1347628548100%2C%22iStart%22%3A0%2C%22iEnd%22%3A0%2C%22iLength%22%3A10%2C%22sFilter%22%3A%22%22%2C%22sFilterEsc%22%3Atrue%2C%22aaSorting%22%3A%5B%20%5B7%2C%22desc%22%5D%5D%2C%22aaSearchCols%22%3A%5B%20%5B%22%22%2Ctrue%5D%2C%5B%22%22%2Ctrue%5D%2C%5B%22%22%2Ctrue%5D%2C%5B%22%22%2Ctrue%5D%2C%5B%22%22%2Ctrue%5D%2C%5B%22%22%2Ctrue%5D%2C%5B%22%22%2Ctrue%5D%2C%5B%22%22%2Ctrue%5D%2C%5B%22%22%2Ctrue%5D%2C%5B%22%22%2Ctrue%5D%2C%5B%22%22%2Ctrue%5D%2C%5B%22%22%2Ctrue%5D%2C%5B%22%22%2Ctrue%5D%2C%5B%22%22%2Ctrue%5D%2C%5B%22%22%2Ctrue%5D%2C%5B%22%22%2Ctrue%5D%2C%5B%22%22%2Ctrue%5D%5D%2C%22abVisCols%22%3A%5B%20false%2Ctrue%2Cfalse%2Ctrue%2Ctrue%2Ctrue%2Ctrue%2Ctrue%2Ctrue%2Cfalse%2Cfalse%2Cfalse%2Cfalse%2Ctrue%2Cfalse%2Cfalse%2Cfalse%5D%7D"];

里面的价值只是从我从网站上捕获的内容进行复制和粘贴。
谁能说出我做错了什么？

这条长长的gobbledy-gook字符串中有一大堆未转义的%字符。如果其中任何一个转换为格式字符串模式，它将尝试从stringWithFormat:调用中获取不存在的参数并构造格式化字符串。
请勿使用stringWithFormat:。鉴于它是一个静态字符串，只需使用裸@"....gobbledy-gook.....";。

您要求格式化字符串，'％'是format specifier。
换句话说，-stringWithFormat需要加倍 - %（如%%）才能在结果字符串中生成一个百分比。否则，它希望您使用上面链接中的一个说明符。
您的意思是简单地分配字符串，例如？

%字符串中的cookie1符号会丢弃解析器。如果您想要实际的百分号，请使用%%代替%。
或者：由于您没有在该字符串中添加任何其他内容，因此您也可以使用stringWithString方法而不是stringWithFormat。或者只是@"your cookie"。
