设备方向没有得到。
问题描述:
目前我正在研究IOS 7,我的问题是我无法在ViewDidLoad方法中获取当前设备的方向。
Currently i am working on IOS 7 and my problem is i am not able to get orientation of current device in ViewDidLoad method.
- (BOOL)shouldAutorotate
{
return YES;
}
- (NSUInteger)supportedInterfaceOrientations
{
return (UIInterfaceOrientationMaskAll);
}
- (void)viewDidLoad
{
[super viewDidLoad];
if (UIDeviceOrientationIsLandscape([UIDevice currentDevice].orientation)){
NSLog(@"i am in landscape mode");
}
if (UIDeviceOrientationIsPortrait([UIDevice currentDevice].orientation)){
NSLog(@"i am in portrait mode");
}
}
我在 FirstViewController.m
,当我运行我的应用程序时,没有任何条件成为现实,
任何人都可以帮助我为什么没有条件变为真,即使我在纵向模式下运行我的应用程序。
提前致谢。

答
试试这个。
UIInterfaceOrientation orientation = [UIApplication sharedApplication].statusBarOrientation;
if(UIInterfaceOrientationIsLandscape(orientation)) {
//Landscape mode
}
else
{
//Portrait mode
}
编辑:使用 UIInterfaceOrientationIsLandscape
和 UIInterfaceOrientationIsPortrait
查找方向模式的方法
