XCode5下实现捕获Javascript的alert

升级xcode4.6至xcode5后，发现工程编译报错。

解决方法比较简单，改成如下代码即可：

@interface ToolDetailViewController (customJavascriptAlert)

- (void)webView:(UIWebView *)sender runJavaScriptAlertPanelWithMessage:(NSString *)message initiatedByFrame:(UIWebView *)frame;

@end


//实现uiwebview协议，自定义alert展示
@implementation UIWebView (customJavascriptAlert)
- (void)webView:(UIWebView *)sender runJavaScriptAlertPanelWithMessage:(NSString *)message initiatedByFrame:(UIWebView *)frame {
    UIAlertView* customAlert = [[UIAlertView alloc] initWithTitle:nil message:message delegate:nil cancelButtonTitle:@"确定" otherButtonTitles:nil];
    
    [customAlert show];
}
@end
