Question

目前我正在使用此方法来检测方向和设备：

适用于iPhone，但这是iPad的问题，无论方向如何，[[UIScreen mainScreen] bounds].size.width总是== 768，[[UIScreen mainScreen] bounds].size.height总是== 1024.我的编码有什么问题？< / p>

 +(NSString*)GetOrientation{
    if([UIScreen mainScreen].bounds.size.width < [UIScreen mainScreen].bounds.size.height){
        NSLog(@"Potrait");
        return @"Potrait";
    }
    else{
        NSLog(@"Landscape");
        return @"Landscape";
    }


}
+(NSString*)GetDeviceAccordingToScreenSize:(UIViewController*)ctrl{
    if ([[UIDevice currentDevice].model isEqualToString:@"iPad"]) {
        int screenWidth = [[UIScreen mainScreen] bounds].size.width;
        if (screenWidth==768) {
            return @"P-iPad";

        }else if(screenWidth==1024){
            return @"L-iPad";

        }else{
        return @"ERROR";
        }
    }else{
        if ([[self GetOrientation] isEqualToString:@"Potrait"]) {
            int screenHeight = [[UIScreen mainScreen] bounds].size.height;
            switch (screenHeight) {
                case 667:{
                    return @"P-iPhone6";
                    break;
                }

                case 736:{
                    return @"P-iPhone6Plus";
                    break;
                }
                case 568:{
                    return @"P-iPhone5";

                }
                default:{
                    return @"P-iPhone4";
                    break;
                }
            }
        }else{
            int screenWidth = [[UIScreen mainScreen] bounds].size.width;
            // float screenHeight = [[UIScreen mainScreen] bounds].size.height;
            switch (screenWidth) {
                case 667:{
                    return @"L-iPhone6";
                    break;
                }

                case 736:{
                    return @"L-iPhone6Plus";
                    break;
                }
                case 568:{

                    return @"L-iPhone5";
                    break;
                }
                default:{
                    return @"L-iPhone4";
                    break;
                }
            }

        }

    }

}

顺便说一下，在扩展程序中，您无权访问[UIApplication sharedApplication]

Answer 1

嗯，iOS8有一些变化，现在[UIScreen bounds]是面向接口的所以宽度总是768。

参考：

Is [UIScreen mainScreen].bounds.size becoming orientation-dependent in iOS8?

Answer 2

您应该使用 nativeBounds 而不是边界来确保结果不会取决于应用程序在启动时的设备方向。

extension UIDevice{
    var detail:String {
        if iPhone {
            if UIScreen.mainScreen().nativeBounds.height == 480 {
                return "iPhone Classic"
            }
            if UIScreen.mainScreen().nativeBounds.height == 960 {
                return "iPhone 4 or 4S"
            }
            if UIScreen.mainScreen().nativeBounds.height == 1136 {
                return "iPhone 5 or 5S or 5C"
            }
            if UIScreen.mainScreen().nativeBounds.height == 1334 {
                return "iPhone 6"
            }
            if UIScreen.mainScreen().nativeBounds.height == 2208 {
                return "iPhone 6+"
            }
        } else if iPad {
            if UIScreen.mainScreen().nativeBounds.height == 1024 {
                return "iPad Classic"
            }
            if UIScreen.mainScreen().nativeBounds.height == 2048 {
                return "iPad Retina"
            }
        } else {
            return "Undefined"
        }

        return "test"
    }
    var iPhone:Bool {
        return UIDevice.currentDevice().userInterfaceIdiom == .Phone
    }
    var iPad:Bool {
        return UIDevice.currentDevice().userInterfaceIdiom == .Pad
    }
    var width:CGFloat{
        return UIScreen.mainScreen().bounds.width
    }  
    var landscape:Bool {
        if iPad && ( width == 1024.0 || width == 2048.0 ) {
            return true
        }
        if iPhone && ( width == 480.0 || width == 960 || width == 1136.0 || width == 1334.0 || width == 2208.0 ) {
            return true
        }
        return false
    }
}
if UIDevice().iPhone {
   println("This device is an iPhone")
}
if UIDevice().iPad {
    println("This device is an iPad")
}
println("Device detail: " + UIDevice().detail )
println("Landscape: " + UIDevice().landscape.description )

我自己解决了这个问题，希望能帮到别人。

我使用xib来构建键盘的界面。这个键盘在iPhone和iPad上运行，因此我设置了4个xib（iPhone横向，纵向，iPad横向，纵向）。我忘了禁用iPad的大小等级。在我禁用它之后，它完美地运行

如何在iOS8键盘扩展中检测iPad方向
