Objective c 使用NSLog打印navigationType

Objective c 使用NSLog打印navigationType,objective-c,ios,xcode,Objective C,Ios,Xcode,我有以下一段: - (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType *)navigationType { NSURL * url = [request URL]; NSRegularExpression* regex = [[NSRegularExpression alloc]

我有以下一段:

- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType *)navigationType {
    NSURL * url = [request URL];
    NSRegularExpression* regex = [[NSRegularExpression alloc] initWithPattern:@"loggedout" options:(NSRegularExpressionOptions)NSCaseInsensitiveSearch error:NULL];
    NSString *urlString = [url absoluteString];
    NSUInteger numberOfMatches = [regex numberOfMatchesInString:urlString options:0 range:NSMakeRange(0, [urlString length])];    
    [regex release];
    if (numberOfMatches > 0) {
//        NSLog(@"%@", url);
//        NSLog(@"%i", numberOfMatches);
        [self.navigationController popViewControllerAnimated:YES]; 
        return NO;
    }
    if (UIWebViewNavigationTypeLinkClicked == navigationType)
    {
        [[UIApplication sharedApplication] openURL:url];
        return NO;
    }
    return YES;
}

我想用NSLog打印“navigationType”变量,但找不到与该变量兼容或不会导致应用程序崩溃的格式说明符(例如:@“%@”或@“%d”)。有人能提供建议吗?

试试
NSLog(@“NavigationType:%i”,NavigationType)

UIWebViewNavigationTypeLinkClicked
上的typedef是否为
NSInteger

使用
%lu
格式说明符打印出值
