最近項目需要兼容iPad，由于項目使用xib和Storyboard，故記錄對iPhone和iPad的適配！
iPhone和ipad適配分為兩種種：
1.為iPad和iPhone分別開發(fā)不同的項目（適合兩個項目區(qū)別比較大，要分別發(fā)布）
2.一個項目同時兼容iPhone和iPad；
本文只對第二種情況（一個安裝包同時兼容iPhone和ipad）
要在一個工程中兼容ipad和iPhone步驟：
1.設(shè)置targets->Deployment Info ->Devices 選擇Universal
Storyboard：
2.選中storyboard文件，假設(shè)名字為Main.storyboard；
3.File--->duplicate，將文件命名為Main_ipad.storyboard:(注意一點要設(shè)置為_ipad,需要和下面的代碼匹配)
4.右鍵Main_ipad.storyboard，open as ---> source code，找到targetRuntime，將其修改為targetRuntime="iOS.CocoaTouch.iPad"
5、調(diào)用storyboardWithName方法改為storyboardAdapter；
針對5需要為UIStoryboard建類別UIStoryboard+Adapter
UIStoryboard+Adapter.h
#import
@interfaceUIStoryboard (Adapter)
+ (UIStoryboard*_Nullable)storyboardAdapter:(nonnullNSString*)name bundle:(nullableNSBundle*)storyboardBundleOrNil;
@end
UIStoryboard+Adapter.m
#import"UIStoryboard+Adapter.h"
@implementationUIStoryboard (Adapter)
+ (UIStoryboard*)storyboardAdapter:(NSString*)name bundle:(nullableNSBundle*)storyboardBundleOrNil
{
UIStoryboard*storyBoard;
if((UI_USER_INTERFACE_IDIOM()==UIUserInterfaceIdiomPad)) {
NSString*ipad = [namestringByAppendingString:@"_ipad"];
storyBoard = [UIStoryboardstoryboardWithName:ipadbundle:storyboardBundleOrNil];
}
else
{
storyBoard = [UIStoryboardstoryboardWithName:namebundle:storyboardBundleOrNil];
}
returnstoryBoard;
}
@end
使用方法：
UIStoryboard*storyBoard = [UIStoryboard storyboardAdapter:@"Main"bundle:nil];
Xib:
前四步一樣，第五步：需要新建UIViewController類別?UIViewController+Adapter
UIViewController+Adapter.h
@interfaceUIViewController (Adapter)
- (instancetype_Nullable)initWithAdapterNibName:(nullableNSString*)nibNameOrNil bundle:(nullableNSBundle*)nibBundleOrNil;
@end
UIViewController+Adapter.m
@implementationUIViewController (Adapter)
- (instancetype)initWithAdapterNibName:(nullableNSString*)nibNameOrNil bundle:(nullableNSBundle*)nibBundleOrNil
{
UIViewController*tmpVC;
if((UI_USER_INTERFACE_IDIOM()==UIUserInterfaceIdiomPad)) {
NSString*ipad = [nibNameOrNilstringByAppendingString:@"_ipad"];
tmpVC = [selfinitWithNibName:ipadbundle:nibBundleOrNil];
}
else
{
tmpVC = [selfinitWithNibName:nibNameOrNilbundle:nibBundleOrNil];;
}
returntmpVC;
}
@end
最后針對ipad和iPhone圖片的兼容：
使用Assets.xcassets選擇圖片后->Devices中選擇iPhone和iPad
