我试图让它运行...我已经放入NSLogs，但是当我更改页面时，调试器中什么也没有出现。
这是我的代码：
#import "ViewController.h"
@interface ViewController ()
@end
@implementation ViewController
@synthesize webview;
- (void)viewDidLoad
{
[super viewDidLoad];
self.webview.delegate = self;
NSString *path = [[NSBundle mainBundle] pathForResource:@"menu" ofType:@"html" inDirectory:@"pages"];
NSURL *url = [NSURL fileURLWithPath:path];
NSURLRequest *request = [NSURLRequest requestWithURL:url];
[self.webview loadRequest:request];
NSLog(@"%@",[[request URL] absoluteString]); //this log appears when the ipad simulator starts
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
以下部分似乎没有运行（调试器中没有日志！）
- (BOOL)webview:(UIWebView*)aWebView shouldStartLoadWithRequest:(NSURLRequest*)request navigationType:(UIWebViewNavigationType)navigationType
{
NSLog(@"%@",[[request URL] absoluteString]);
NSString *absoluteUrl = [[request URL] absoluteString];
if ([absoluteUrl isEqualToString:@"didtap://button1"]) {
NSLog(@"Button tapped");
return NO;
}
return YES;
}
检查您的委托方法的大写；它应该是：
- (BOOL)webView:(UIWebView*)aWebView shouldStartLoadWithRequest:(NSURLRequest*)request navigationType:(UIWebViewNavigationType)navigationType
即webView不是webview。
