如何在 iOS8 键盘扩展中检测 iPad 方向
How to detect iPad orientation in iOS8 keyboard extension
目前我正在使用这种方法来检测方向和设备:
它适用于 iPhone,但这是 iPad 的一个问题,无论方向是什么,[[UIScreen mainScreen] bounds].size.width
始终 ==768,而 [[UIScreen mainScreen] bounds].size.height
始终 == 1024。什么是我的编码有问题吗?
+(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,在扩展中您无权访问 [UIApplication sharedApplication]
嗯,iOS8 有一些变化,
现在 [UIScreen bounds] 是面向界面的
所以宽度总是768.

Is [UIScreen mainScreen].bounds.size becoming orientation-dependent in iOS8?
我自己解决了这个问题,希望对大家有所帮助。
我用xib搭建了键盘的界面。这个键盘 运行 在 iPhone 和 iPad 上都有,所以我设置了 4 个 xibs。(iPhone 横向,纵向,iPad 横向,纵向)。我忘记为 iPad 禁用大小 类。在我禁用它之后,它完美地工作
您应该使用 nativeBounds 而不是边界,以确保结果不依赖于应用程序启动时的设备方向。
