1，去掉StatusBar
在info.plist添加UIStatusBarHidden设置Boolean，设置为YES.
2，横屏
继续在info.list中添加UIInterfaceOrientation 设置UIInterfaceOrientationLandscapeRight
xcode 4.3.2中为Inital interface orientation 设置为Landscape (right home button)
当然你输入上面的，xcode也会为你纠正，所以两种都可以！
3，重力感应
AppDelegate继承UIAccelerometerDelegate协议，并实现
// Implement this method to get the lastest data from the accelerometer
- (void)accelerometer:(UIAccelerometer*)accelerometer didAccelerate:(UIAcceleration*)acceleration {
//Use a basic low-pass filter to only keep the gravity in the accelerometer values{}
在
- (void)applicationDidFinishLaunching:(UIApplication *)application {
}
添加
//Configure and start accelerometer
[[UIAccelerometer sharedAccelerometer] setUpdateInterval:(1.0 / kAccelerometerFrequency)];
[[UIAccelerometer sharedAccelerometer] setDelegate:self];
就可以实现重力感应
4,自动切换横竖。
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation //支持横 竖转动
{
return YES;
}
- (void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration //当发生旋转 时
{
f(self.interfaceOrientation==UIInterfaceOrientationPortrait||self.interfaceOrientation==UIDeviceOrientationPortraitUpsideDown)
{
//横 转向 竖
}
}
- (void)didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation //旋转 完成
{ if(self.interfaceOrientation==UIInterfaceOrientationPortrait||self.interfaceOrientation==UIDeviceOrientationPortraitUpsideDown)
{
//当前是在竖屏模式
}
}
横屏之间切换
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation //支持横 竖转动
{
if (interfaceOrientation == UIInterfaceOrientationLandscapeRight )
{
return YES;
}
else if (interfaceOrientation == UIInterfaceOrientationLandscapeLeft)
{
return YES;
}
return NO;
}

以下未经过测试
使用重力感应，判断手机的方向，然后设定[UIApplication sharedApplication].statusBarOrientation = UIInterfaceOrientationLandscapeRight,以及UIInterfaceOrientationPortrait,就可以做到根据不同的手机方向弹出横屏还是竖屏的对话框了，包括对话框上包含输入框的键盘也可以自动旋转了

5，开机画面横屏
