我正在研究这款仅支持横向定位的cocos2D应用。这个UIView正在垂直显示,就像设备处于纵向方向一样。我有两个问题:
以下是视图控制器中的代码:
// this method is called from init
-(void) addLoadingView {
CGSize size = [[CCDirector sharedDirector] winSize];
_blockerView = [[[UIView alloc]
initWithFrame: CGRectMake(0, 0, 280, 60)] autorelease];
_blockerView.backgroundColor = [UIColor colorWithWhite: 0.0 alpha: 0.8];
_blockerView.center = CGPointMake(size.width/2, size.height/2);
_blockerView.alpha = 0.0;
_blockerView.clipsToBounds = YES;
if ([_blockerView.layer respondsToSelector: @selector(setCornerRadius:)])
[(id) _blockerView.layer setCornerRadius: 10];
_blockerLabel = [[[UILabel alloc] initWithFrame: CGRectMake(0, 5, _blockerView.bounds.size.width, 15)] autorelease];
_blockerLabel.text = NSLocalizedString(@"Please Wait...", nil);
_blockerLabel.backgroundColor = [UIColor clearColor];
_blockerLabel.textColor = [UIColor whiteColor];
_blockerLabel.textAlignment = UITextAlignmentCenter;
_blockerLabel.font = [UIFont boldSystemFontOfSize: 15];
[_blockerView addSubview: _blockerLabel];
UIActivityIndicatorView *spinner = [[[UIActivityIndicatorView alloc]
initWithActivityIndicatorStyle: UIActivityIndicatorViewStyleWhite] autorelease];
spinner.center = CGPointMake(_blockerView.bounds.size.width / 2, _blockerView.bounds.size.height / 2 + 10);
[_blockerView addSubview: spinner];
[self.view addSubview: _blockerView];
[spinner startAnimating];
}
-(void) showLoadingGraphics:(NSString*)textInView{
_blockerView.alpha = 1.0;
_blockerLabel.text = NSLocalizedString(textInView, nil);
}
更新
我发现如果将它添加到openGLView那就没关系了。
[[[CCDirector sharedDirector] openGLView] addSubview: _blockerView];
而不是
[self.view addSubview: _blockerView];
作品
我怀疑它当前的视图是以某种方式旋转的。

请检查视图控制器以获取名为shouldAutorotateToInterfaceOrientation的方法:你的回答应该是这样的:
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
// Return YES for supported orientations
return (interfaceOrientation == UIInterfaceOrientationLandscapeLeft ||
interfaceOrientation == UIInterfaceOrientationLandscapeRight);
}
他们的标签栏控制器是否存在?如果是这样,那就是一个潜在的问题:标签栏的所有视图控制器都需要就方向达成一致。

您是否在项目属性列表纵向方向上打开了?
<key>UISupportedInterfaceOrientations</key>
<array>
<string>UIInterfaceOrientationPortrait</string>
<string>UIInterfaceOrientationLandscapeRight</string>
<string>UIInterfaceOrientationLandscapeLeft</string>
</array>
