我收到了以下崩溃报告(截断)
Exception Type: EXC_CRASH (SIGSEGV)
Exception Codes: 0x00000000, 0x00000000

6 UIKit 0x37921bbe -[UIWebDocumentView loadHTMLString:baseURL:] + 78
关注的是调用代码如下所示:
@try {
[webView loadHTMLString:htmlString baseURL:nil];
[webView setNeedsDisplay];
}
@catch (NSException *exception) {...}
那么,我是如何设法从异常处理程序中抛出异常的呢？ …
