[英]Device Orientation in iphone sdk
我對ipad有要求,可以同時顯示橫向和縱向內容。.所以我已經完成了代碼,並完成了各個方向上的控件位置。工作正常。.我的代碼是
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
if (interfaceOrientation == UIInterfaceOrientationLandscapeRight ||interfaceOrientation == UIInterfaceOrientationLandscapeLeft ) {
_viewContainer.frame = CGRectMake(342, 1, 681, 707);
_viewtopic.frame = CGRectMake(1, 62, 343, 56);
_viewpublicspeekingheaderleft.frame = CGRectMake(0, 6, 341, 58);
_viewTableview.frame = CGRectMake(1, 118, 341, 590);
_viewFooter.frame = CGRectMake(1, 716, 1024, 48);
if (interfaceOrientation == UIInterfaceOrientationPortrait ||interfaceOrientation == UIInterfaceOrientationPortraitUpsideDown ) {
_viewContainer.frame = CGRectMake(276, 1, 503, 946);
_viewtopic.frame = CGRectMake(0, 58, 275, 50);
_viewpublicspeekingheaderleft.frame = CGRectMake(0, 1, 275, 58);
_viewTableview.frame = CGRectMake(1, 109, 274, 837);
_viewFooter.frame = CGRectMake(1, 954, 767, 48);
}
return YES;
}
上面的代碼對我來說很好,我將所有控制器都放在了corect位置..這是我的問題,我必須設置一個計時器以顯示全屏,並且我需要在viewcontroller中隱藏一些控制器,我已經完成了計時器設置為3秒,然后3秒后,它隱藏了一些控件並在視圖控制器中安排了其他控件以顯示ful sceen。它對我來說也很好。
- (void)viewDidLoad
{
[super viewDidLoad];
// Define the timer object
NSTimer *timer;
// Create the timer object
timer = [NSTimer scheduledTimerWithTimeInterval:3.0 target:self
selector:@selector(updateorientation:) userInfo:nil repeats:NO];
}
- (void) updateorientation:(NSTimer *)incomingTimer
{
_tableTopic.hidden =YES;
_viewtopic.hidden =YES;
_viewpublicspeekingheaderleft.hidden =YES;
_viewTableview.hidden =YES;
_imgpulbicspeakingabovethetableview.hidden =YES;
_topiclabel.hidden =YES;
_lblpublicspeekingleft.hidden =YES;
UIInterfaceOrientation orientation =[[UIApplication sharedApplication] statusBarOrientation];
if (orientation == UIDeviceOrientationPortrait || orientation == UIDeviceOrientationPortraitUpsideDown ) {
NSLog(@"portrait");// only works after a rotation, not on loading app
_imgMicimage.frame = CGRectMake(69, 130, 635, 216);
_txtContentofTopic.frame = CGRectMake(69, 354, 635, 203);
_viewContainer.frame = CGRectMake(0, 0, 768, 1024);
}
UIInterfaceOrientation orientationLandscape =[[UIApplication sharedApplication] statusBarOrientation];
if (orientationLandscape == UIDeviceOrientationLandscapeLeft || orientationLandscape == UIDeviceOrientationLandscapeRight ) {
NSLog(@"landscape");
_imgMicimage.frame = CGRectMake(93, 113, 836, 239);
_txtContentofTopic.frame = CGRectMake(93, 360, 836, 203);
_viewContainer.frame = CGRectMake(0, 0, 1024, 768);
}
}
它工作正常,但是在計時器觸發后,然后我改變了設備的方向,我只在- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
應該AutorotateToInterfaceOrientation - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
function。解決這個。
提前致謝。
}
您不應該在-shouldAutorotateToInterfaceOrientation:
進行這項工作。 該方法只是確定您的UI是否應該旋轉(不久將被新系統取代)。 您應該使用以下方法來布局UI以響應實際的輪換:
-willRotateToInterfaceOrientation:duration:
-willAnimateRotationToInterfaceOrientation:duration:
-didRotateFromInterfaceOrientation:
有關更多信息,請參閱UIViewController
文檔 。
在iOS 5上, -viewWillLayoutSubviews
可能是另一個不錯的選擇。 (即使當前不顯示控制器的視圖,也會調用它。)
