我想在用户更改设备的方向时更新UI内容。 我使用以下代码在-viewDidLoad事件创建一个UITableView。
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view.
self.view.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleBottomMargin |
UIViewAutoresizingFlexibleLeftMargin | UIViewAutoresizingFlexibleRightMargin |
UIViewAutoresizingFlexibleTopMargin | UIViewAutoresizingFlexibleBottomMargin;
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(orientationChanged:) name:UIDeviceOrientationDidChangeNotification object:nil];
self.tv = [[UITableView alloc]initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height)];
self.tv.backgroundColor = [UIColor redColor];
self.tv.autoresizesSubviews = YES;
self.tv.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleBottomMargin |
UIViewAutoresizingFlexibleLeftMargin | UIViewAutoresizingFlexibleRightMargin |
UIViewAutoresizingFlexibleTopMargin | UIViewAutoresizingFlexibleBottomMargin;
self.tv.delegate = self;
self.tv.dataSource = self;
[self.view addSubview:self.tv];
}
我使用以下事件处理方向更改但我无法将tableview缩放到屏幕。 你能帮我找一下我错过的东西吗？
#pragma mark - orientation events
-(BOOL)shouldAutorotate
{
return YES;
}
- (void)orientationChanged:(NSNotification *)notification{
[self adjustViewsForOrientation:[[UIApplication sharedApplication] statusBarOrientation]];
}
-(void) adjustViewsForOrientation:(UIInterfaceOrientation) orientation {
[self.tv reloadData];
if( orientation == UIInterfaceOrientationPortrait || orientation == UIInterfaceOrientationPortraitUpsideDown){
}
if( orientation == UIInterfaceOrientationLandscapeLeft || orientation == UIInterfaceOrientationLandscapeRight) {
}
}
