纵向问题

Question

 -(void)search:(id)sender {

    if (([[UIDevice currentDevice]orientation]==UIDeviceOrientationLandscapeLeft)||([[UIDevice currentDevice]orientation]==UIDeviceOrientationLandscapeRight)) {
        [self landscapeTextField];
    }

        else if (([[UIDevice currentDevice] orientation] == UIDeviceOrientationPortrait) || ([[UIDevice currentDevice] orientation] == UIDeviceOrientationPortraitUpsideDown)) {    
            [self portraitSearchTextField];
    }
    }

我在点击应用程序按钮时调用此函数。

当我处于纵向模式时[self portraitSearchTextField]未调用

我检查了调试模式。

当我将else if替换为else [self portraitSearchTextField];其工作

时

但在应用程序加载时我的当前设备处于纵向模式...为什么不执行此条件。任何人都可以帮助我。

@thanks提前。

试试这个：

    -(void)search:(id)sender {

    if (([[UIDevice currentDevice]orientation]==UIDeviceOrientationLandscapeLeft)||([[UIDevice currentDevice]orientation]==UIDeviceOrientationLandscapeRight)) {
            [self landscapeTextField];
    }

    else { 
        if (([[UIDevice currentDevice] orientation] == UIDeviceOrientationPortrait) || ([[UIDevice currentDevice] orientation] == UIDeviceOrientationPortraitUpsideDown)) {    
            [self portraitSearchTextField];
        }
    }
}
