Question

我使用FB graph api将我的ios应用程序与facebook集成。但登录时弹出webview，第一个问题是它没有取消按钮我仍然按下一个按钮应用一个动作，但无法从我来的地方进入那个屏幕。

NSString *url_string = [NSString stringWithFormat:@"https://graph.facebook.com/oauth/authorize?client_id=%@&redirect_uri=%@&scope=%@&type=user_agent&display=touch", facebookClientID, redirectUri, extended_permissions];
NSURL *url = [NSURL URLWithString:url_string];
NSURLRequest *request = [NSURLRequest requestWithURL:url];

CGRect webFrame = [super_view frame];

webFrame.origin.y = 0;
UIWebView *aWebView = [[UIWebView alloc] initWithFrame:webFrame];
[aWebView setDelegate:self];    
self.webView = aWebView;

UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
button.frame = CGRectMake(5.0, 10, 150.0, 30.0);
[button setTitle:@"My Button" forState:UIControlStateNormal];
[button addTarget:self action:@selector(myAction:) forControlEvents:UIControlEventTouchUpInside];
[self.webView addSubview:button];
[aWebView release];

[webView loadRequest:request];  
[super_view addSubview:webView];
