- 1.界面旋轉(zhuǎn)，MainScreen的寬高不變，鍵盤位置不變
'''

復(fù)制代碼
if ([[UIDevice currentDevice] respondsToSelector:@selector(setOrientation:)]) {
SEL selector = NSSelectorFromString(@"setOrientation:");
NSInvocation *invocation = [NSInvocation invocationWithMethodSignature:[UIDevice instanceMethodSignatureForSelector:selector]];
[invocation setSelector:selector];

3.界面旋轉(zhuǎn)，MainScreen的寬高改變，鍵盤位置改變
a.General—>中勾選Lnadscape Left/Lnadscape Right
Pasted Graphic.tiff
b.控制器中實(shí)現(xiàn)以下兩個(gè)方法：
復(fù)制代碼
// 支持設(shè)備自動(dòng)旋轉(zhuǎn)
- (BOOL)shouldAutorotate
{
return YES;
}
/**
*? 設(shè)置特殊的界面支持的方向,這里特殊界面只支持Home在右側(cè)的情況
*/
- (UIInterfaceOrientationMask)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskLandscapeRight;
}
復(fù)制代碼
PS：如何判斷當(dāng)前是否橫屏,一下3個(gè)方法都可以
self.interfaceOrientation（iOS 2.0~8.0）
[UIApplication sharedApplication] statusBarOrientation]
[[UIDevice currentDevice] orientation]
