问题描述
假设我有三个UI控制器(A,B,C)。
Lets say I have three UI Controllers (A,B,C).
A是我的根控制器,在ShouldAutoRotate方法中我返回YES。
我做的是从A到B的ModalView(B =>在ShouldAutoRotate方法中我返回Portrait)然后从BI执行presentModal到C(C应该能够旋转到任何方向)。
A is my root controller and inside the ShouldAutoRotate method I return YES.I do presentModalView from A to B (B=>inside the ShouldAutoRotate method I return Portrait) then from B I do presentModal to C (C should be able to rotate to any orientation).
现在在C里面我能够将模拟器旋转到任何方向,整个视图完全旋转。这就是问题,当C是Landscape并且我解雇它时,B里面的所有对象都会变成弄乱!!同样的事情发生在A。
Now inside C I'm able to rotate the simulator to any orientation, and the whole View rotates perfectly.Here is the problem, when C is Landscape and I dismiss it, all the objects inside B will become messed up!! same thing happens to A.
我只需要在C上进行轮换!!
I just need to have the rotation on C!!
感恩。
推荐答案
在App代理中
@interface AppDelegate : UIResponder <UIApplicationDelegate>
@property (nonatomic) BOOL shouldRotate;
@end
- (NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window{
if (self.shouldRotate == YES) {
return UIInterfaceOrientationMaskLandscapeLeft | UIInterfaceOrientationMaskLandscapeRight | UIInterfaceOrientationMaskPortrait;
}
return UIInterfaceOrientationMaskPortrait;
}
在viewController A中,B
In viewController A,B
- (void)viewWillAppear:(BOOL)animated{
[super viewWillAppear:animated];
((AppDelegate *)[[UIApplication sharedApplication] delegate]).shouldRotate = NO;
[self supportedInterfaceOrientations];
[self shouldAutorotate:UIInterfaceOrientationPortrait];
[[UIApplication sharedApplication] setStatusBarOrientation:UIInterfaceOrientationPortrait animated:NO];
}
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
// Return YES for supported orientations
return (interfaceOrientation == UIInterfaceOrientationPortrait);
}
- (BOOL)shouldAutorotate:(UIInterfaceOrientation)interfaceOrientation{
// Return YES for supported orientations
return (interfaceOrientation == UIInterfaceOrientationPortrait);
}
-(NSUInteger)supportedInterfaceOrientations{
return UIInterfaceOrientationMaskPortrait;
}
在viewController C中
In viewController C
- (void)viewWillAppear:(BOOL)animated{
[super viewWillAppear:animated];
((AppDelegate *)[[UIApplication sharedApplication] delegate]).shouldRotate = YES;
}
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
return YES;
}
- (BOOL)shouldAutorotate:(UIInterfaceOrientation)interfaceOrientation{
return YES;
}
-(NSUInteger)supportedInterfaceOrientations{
return UIInterfaceOrientationMaskPortrait|UIInterfaceOrientationMaskLandscapeLeft | UIInterfaceOrientationMaskLandscapeRight;
}
- (IBAction)closeVC:(id)sender {
NSNumber *value = [NSNumber numberWithInt:UIInterfaceOrientationPortrait];
[[UIDevice currentDevice] setValue:value forKey:@"orientation"];
AppDelegate *appDelegate = (AppDelegate *)[[UIApplication sharedApplication] delegate];
appDelegate.shouldRotate = NO;
[self supportedInterfaceOrientations];
[self shouldAutorotate:UIInterfaceOrientationPortrait];
[self dismissViewControllerAnimated:YES completion:nil];
}
