一歉甚、給UItabBarController万细、UINavigationController，并添加如下代碼
- (BOOL)shouldAutorotate{
return YES;
}
二纸泄、在appdelegate中添加一個屬性_allowRotate
- (UIInterfaceOrientationMask)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window
{
// NSLog(@"方向 ============= %ld", _allowRotate);
if ([_allowRotate isEqualToString:@"1"]) {
return UIInterfaceOrientationMaskAll;
}else{
return (UIInterfaceOrientationMaskPortrait);
}
}
// 返回是否支持設(shè)備自動旋轉(zhuǎn)
- (BOOL)shouldAutorotate
{
if ([_allowRotate isEqualToString:@"1"]) {
return YES;
}
return NO;
}
三赖钞、最后在需要橫屏的頁面中添加如下代碼
- (void)viewWillAppear:(BOOL)animated
{
[super viewWillAppear:animated];
App_Delegate.allowRotate = @"1";
}
- (void)viewWillDisappear:(BOOL)animated{
[super viewWillDisappear:animated];
App_Delegate.allowRotate = @"0";
if ([[UIDevice currentDevice] respondsToSelector:@selector(setOrientation:)]) {
SEL selector = NSSelectorFromString(@"setOrientation:");
NSInvocation *invocation = [NSInvocation invocationWithMethodSignature:[UIDevice instanceMethodSignatureForSelector:selector]];
[invocation setSelector:selector];
[invocation setTarget:[UIDevice currentDevice]];
int val = UIInterfaceOrientationPortrait;
[invocation setArgument:&val atIndex:2];
[invocation invoke];
}
}
四、在Deployment Info中設(shè)置如下
