大家好 我有一个基于tabbar的应用程序。在一个视图中,我有一个TTTabStrip与不同的TTTabItems。一切正常(加载普通的UIViewControllers),除了加载UIWebViews。
在app委托中,我设置了url映射:
TTNavigator* navigator = [TTNavigator navigator];
navigator.supportsShakeToReload = YES;
navigator.persistenceMode = TTNavigatorPersistenceModeAll;
TTURLMap* map = navigator.URLMap;
[map from:@"*" toViewController:[TTWebController class]]; // default klasse wenn nichts anderes gewählt ist.
[map from:@"tt://test" toViewController:[TestController class]];
测试控制器包含一个UIWebView。我可以看到(NSLog)调用loadView-Method,但是没有打开URL:
- (void) loadView {
CGRect applicationFrame = [UIScreen mainScreen].applicationFrame;
self.view = [[[UIView alloc] initWithFrame:applicationFrame] autorelease];
//self.view.backgroundColor = [UIColor blackColor];
NSURL *theURL = [NSURL URLWithString:@"http://www.google.com"];
[webView loadRequest:[NSURLRequest requestWithURL:theURL]];
// support zooming
webView.scalesPageToFit = YES;
}
例如,我可以将UIWebView的背景更改为黑色。
如何在TTTabStrip下方的网络视图中加载Google?
非常感谢。
答案 0 :(得分:3)
尝试以下操作并添加方法viewWillAppear:
- (void)loadView
{
CGRect applicationFrame = [UIScreen mainScreen].applicationFrame;
UIView * newView = [[UIView alloc] initWithFrame:applicationFrame];
// support zooming
webView.scalesPageToFit = YES;
[newView addSubview:webView];
self.view = newView;
[newView release];
}
- (void)viewWillAppear:(BOOL)animated
{
[super viewWillAppear:animated];
NSURL *theURL = [NSURL URLWithString:@"http://www.google.com"];
[webView loadRequest:[NSURLRequest requestWithURL:theURL]];
}
