强制设置横向在 xib 中不起作用 [英] Force set Landscape orientation is not working in xib

问题描述

我有以下代码

#define degreesToRadian(x) (M_PI * (x) / 180.0)
if(UIInterfaceOrientationIsPortrait(self.interfaceOrientation)){

    [UIView beginAnimations:@"View Flip" context:nil];
    [UIView setAnimationDuration:0.5f];
    [UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];

    self.view.transform = CGAffineTransformIdentity;
    self.view.transform = CGAffineTransformMakeRotation(degreesToRadian(0));
    self.view.bounds = CGRectMake(0.0f, 0.0f, 1004, 768.0f);
    // self.view.center = CGPointMake(160.0f, 240.0f);

    [UIView commitAnimations];
}

此代码适用于强制设置横向

This code will work fine for force setting landscape orientation

-(NSUInteger)supportedInterfaceOrientations
{
    return UIInterfaceOrientationMaskLandscape;
}

我在 viewdidload 中使用以下代码.此代码在测试应用程序中运行良好，但在我的主应用程序中运行良好.

I am using the following code in viewdidload.This code is working fine in test app but in my mainapp.

if(UIInterfaceOrientationIsPortrait(self.interfaceOrientation)){
    if ([[UIDevice currentDevice] respondsToSelector:@selector(setOrientation:)])
    {
        objc_msgSend([UIDevice currentDevice], @selector(setOrientation:),UIInterfaceOrientationLandscapeLeft);
    }
}

如果我编写测试应用程序就可以正常工作但是在我的 Mainapp 中它不起作用.我的 Mainapp 中有 xib

It is working fine if i write test application But in my Mainapp it is not working.I have xib in my Mainapp

推荐答案

确保您已为 Mainapp 应用程序设置横向模式，

Make sure You have set Landscape mode for your Mainapp Application,

编辑

在 Printview 页面 ios5 和 6 中使用以下方法

Than use Following method in Printview page ios5 and 6

- (NSUInteger)supportedInterfaceOrientations
{
    return UIInterfaceOrientationMaskLandscape;
}


- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    if (UIInterfaceOrientationIsLandscape( interfaceOrientation)) {
        return  YES;
    }
    return NO;

}

iOS 7

-(BOOL)shouldAutorotate
{
    if (UIInterfaceOrientationIsLandscape( [[UIDevice currentDevice] orientation])) {
        return  YES;
    }
    else
        return NO;
}
