Answer 1

我假设你从网上下载了一些资料，并试图建立与该信息的一些部分的字符串：你在哪里都使用的信息，你来自取出

6 CoreFoundation 0x00000001866bc2bc _CFStringCreateWithFormatAndArgumentsAux2 + 272 
7 Foundation 0x0000000187502448 -[NSPlaceholderString initWithFormat:locale:arguments:] + 172 

互联网，你应该首先检查信息是否有效，并尊重你期望的正确格式。因此，我建议您在使用前验证信息。

这可能帮助你： iPhone app crash at [NSString stringWithFormat]

错误行必须是：

[NSString stringWithFormat:@"%@,%@...",a,b...];
