我正在做一个iPhone项目，我需要仅为6,6 Plus和iPad提供纵向和横向支持吗？风景不适用于iPhone 4,5系列。
如何在Objective c中以编程方式执行此操作？

你可以通过这种方法判断。

我们在supportedInterfaceOrientationsFor中有UIApplicationDelegate方法，因此您可以实施它并检查设备高度条件并返回所需的UIInterfaceOrientationMask，如下所示
<强>目标C
- (UIInterfaceOrientationMask)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window {
// iPhone 5 height:: 568
if ([[UIScreen mainScreen] bounds].size.height > 568) {
return UIInterfaceOrientationMaskAll;
} else {
return UIInterfaceOrientationMaskPortrait;
}
}
<强>夫特-3
func application(_ application: UIApplication, supportedInterfaceOrientationsFor window: UIWindow?) -> UIInterfaceOrientationMask {
// iPhone 5 height:: 568
if UIScreen.main.bounds.height > 568 {
return .all
} else {
return .portrait
}
}

- (UIInterfaceOrientationMask)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(nullable UIWindow *)window {
if([[UIDevice currentDevice]userInterfaceIdiom]==UIUserInterfaceIdiomPhone) {
//For iPhone
if ([[UIScreen mainScreen] bounds].size.height >= 568) {
return UIInterfaceOrientationMaskPortrait;
} else {
return UIInterfaceOrientationMaskAll;
}
} else {
//For iPad
//your conditions for iPad
return UIInterfaceOrientationMaskAll
}
}

斯威夫特3：
我选择这种方式：
我无法访问Xcode以在Objective-C中编写它。 也许我稍后会添加Objective-C代码。
首先确定设备型号名称：
public extension UIDevice {
var modelName: String {
var systemInfo = utsname()
uname(&systemInfo)
let machineMirror = Mirror(reflecting: systemInfo.machine)
let identifier = machineMirror.children.reduce("") { identifier, element in
guard let value = element.value as? Int8, value != 0 else { return identifier }
return identifier + String(UnicodeScalar(UInt8(value)))
}
switch identifier {
case "iPod5,1": return "iPod Touch 5"
case "iPod7,1": return "iPod Touch 6"
case "iPhone3,1", "iPhone3,2", "iPhone3,3": return "iPhone 4"
case "iPhone4,1": return "iPhone 4s"
case "iPhone5,1", "iPhone5,2": return "iPhone 5"
case "iPhone5,3", "iPhone5,4": return "iPhone 5c"
case "iPhone6,1", "iPhone6,2": return "iPhone 5s"
case "iPhone7,2": return "iPhone 6"
case "iPhone7,1": return "iPhone 6 Plus"
case "iPhone8,1": return "iPhone 6s"
case "iPhone8,2": return "iPhone 6s Plus"
case "iPhone9,1", "iPhone9,3": return "iPhone 7"
case "iPhone9,2", "iPhone9,4": return "iPhone 7 Plus"
case "iPhone8,4": return "iPhone SE"
case "iPad2,1", "iPad2,2", "iPad2,3", "iPad2,4":return "iPad 2"
case "iPad3,1", "iPad3,2", "iPad3,3": return "iPad 3"
case "iPad3,4", "iPad3,5", "iPad3,6": return "iPad 4"
case "iPad4,1", "iPad4,2", "iPad4,3": return "iPad Air"
case "iPad5,3", "iPad5,4": return "iPad Air 2"
case "iPad2,5", "iPad2,6", "iPad2,7": return "iPad Mini"
case "iPad4,4", "iPad4,5", "iPad4,6": return "iPad Mini 2"
case "iPad4,7", "iPad4,8", "iPad4,9": return "iPad Mini 3"
case "iPad5,1", "iPad5,2": return "iPad Mini 4"
case "iPad6,3", "iPad6,4", "iPad6,7", "iPad6,8":return "iPad Pro"
case "AppleTV5,3": return "Apple TV"
case "i386", "x86_64": return "Simulator"
default: return identifier
}
}
}
然后在AppDelegate中过滤设备方向：
func application(_ application: UIApplication, supportedInterfaceOrientationsFor window: UIWindow?) -> UIInterfaceOrientationMask {
if UIDevice.currentDevice().modelName == "iPhone 4" ||
UIDevice.currentDevice().modelName == "iPhone 5" ||
UIDevice.currentDevice().modelName == "iPhone 4s" ||
UIDevice.currentDevice().modelName == "iPhone 5s" {
return .portrait
} else {
return .all
}
}

检查您的设备屏幕尺寸是否小于或等于iPhone 5 屏幕尺寸，然后仅支持纵向模式。此外，还支持更高屏幕尺寸设备的所有类型方向。在AppDelegate.m fil
中添加此代码- (UIInterfaceOrientationMask)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window {
CGSize screenSize = [[UIScreen mainScreen] bounds].size;
if (screenSize.height <= 568.0) {
// If the screen size is less than or equal to iPhone 5 screen size then only Portrait mode
return UIInterfaceOrientationMaskPortrait;
} else {
// Else Support all the orientation. Even apple introduced new size screen devices, which is greater then iphone 5 screen size, then this will work.
return UIInterfaceOrientationMaskAll;
}
}
