问题 I've recently updated the android studio IDE to 0.8 to work with the new android L SDK. To start I imported a finished android project that receives no errors in the older version of android studio. In version 0.8 i lines such as import android.support.v4.app.Fragment; get: Support cannot be resolved causing the rest of the code to have errors. The logcat returns 101 instances of Error:(8, 30) error: package android.support.v4.app does not exist 1 for each time I call the support library in

跨iOS SDK版本编译问题

狂风中的少年 提交于 2020-01-17 09:39:45
iOS开发时会考虑两种SDK版本兼容性:一个是运行时SDK版本的兼容,即已构建/已发布的APP能在不同系统版本的用户手机上正常运行;一个是编译时SDK版本的兼容,即使用不同版本的SDK编译项目都能正常通过。后者是开发者经常会疏忽的,因为我们通常统一使用最新的SDK来编译项目,很少会再使用老的SDK编译项目,但为了项目的健壮和灵活,我们应该了解一下如何保证编译时的SDK版本兼容。 由于每个版本的iOS SDK,苹果都会增加许多新的功能,因此会有新的类型,新的方法(由于OC的动态特征,新方法不会造成编译问题)等等,开发者会迫不及待的引入到已有的项目中去,但是用老的SDK编译这些新代码时,会出现找不到符号的编译错误。因此我们应该用以下办法屏蔽这些问题。   1.使用类名加载新的类型 WKWebView* webView = [[NSClassFromString(@"WKWebView") alloc] initWithFrame:self.bounds configuration:configuration];   2.使用版本宏区分代码 const BOOL IOS10_OR_LATER = ( [[[UIDevice currentDevice] systemVersion] compare:@"10.0" options:NSNumericSearch] !=

探寻不同版本号的SDK对iOS程序的影响

PDF版本号: http://pan.baidu.com/s/1eQ8DVdo 结论: 同样的代码。使用不同版本号的SDK来编译。会影响MachO头中的值, 从而使程序表现出不同的外观。 代码: - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { UIScreen *mainScreen = [UIScreen mainScreen]; CGRect frm = [mainScreen bounds]; UIWindow *win = [[UIWindow alloc] initWithFrame:frm]; win.backgroundColor = [UIColor blueColor]; self.window = win; [win release]; [self.window makeKeyAndVisible]; return YES; } 问题: 如上的代码很easy,没有不论什么功能, 分别使用 xcode v4.6.3 与 v5.0.2 编译。 然后安装到iOS8的设备上,表现却 不同, 主要就是iOS6与iOS7之间关于状态条的区别。例如以下图: __________ 代码都是一样的

Adding Tab Bar View into an Existing Table Based App - iPhone

问题 I have a table based app and would like to add a tab bar to the bottom to switch between this table and other views. What is the msot hassle free way to do this ? Can I just wire in a tab view controller underneath the table view? Thanks, Martin 回答1: You actually have to load your view controllers into a UITabBarController. So if you have a tableViewController, viewController1, and viewController 2, you want to add all those to the tabBarController. UITabBarController *tabBarController = [

How to create facebook app invited with an external application?

问题 I know how to retrieve data from facebook GRAPH (such as app requests, etc) but what I am wondering how to do, is allow an application to create a facebook application request via http/https (not using the actual facebook dialouge) Is there a backend system to allow apps (with perhaps id and security token info) to manually create application invites so that an app can use its own UI for invitations? (I've seen it done in other apps so I know there has to be some sort of way to do it) An
