我们应该都有用过这个功能，你的朋友微信给你分享了一个淘宝里面的商品链接，然后当你复制这个链接打开淘宝APP的时候，就会弹出一个弹窗，像这样：
example.PNG
这个功能想必大家都挺熟悉，受这个启发我们产品也想在我们APP上添加这样一个功能，与这个不一样的是，当我们复制一段网址的时候打开我们的APP会弹出框填一些信息后上传到我们的“资源库”。大体功能就这样，所以记录一下实现的过程。
一、弹窗视图功能
.h中：两个信号一个是确定信号一个是取消信号
两个方法，一个显示一个隐藏方法
|

|
@property (nonatomic, strong) RACSubject *uploadSureSignal;
//确定上传信号
@property (nonatomic, strong) RACSubject *hideSucSignal;
//隐藏
- (
void
)show;
- (
void
)hide;
|
.m中：主要是两个textview，还有涉及到在keywindow上，IQKeyboard的一些操作
|
1
2
3
|
@property (nonatomic, assign) CGFloat keyboardHeight;
//键盘高度
@property (nonatomic, strong) CustomUITextView *nameTV;
@property (nonatomic, strong) CustomUITextView *desTV;
|
因为发现IQKeyboard在这个弹出界面有问题，所以在显示这个界面的时候，将IQKeyboard禁用取之使用系统的keyboard监听方法
在(void)show方法中：
|
1
2
3
4
5
6
7
8
|
-(
void
)show {
//键盘通知
NSNotificationCenter *defaultCenter = [NSNotificationCenter defaultCenter];
[defaultCenter addObserver:self selector:@selector(keyboardWillShowOrHide:) name:UIKeyboardWillShowNotification object:nil];
[defaultCenter addObserver:self selector:@selector(keyboardWillShowOrHide:) name:UIKeyboardWillHideNotification object:nil];
}

//监听方法
- (
void
)keyboardWillShowOrHide:(NSNotification *)notification {
//获取通知名
NSString *notificationName = notification.name;
//获取通知内容
NSDictionary *keyboardInfo = notification.userInfo;
//键盘弹出时，让画面整体稍稍上移，并伴随动画
//键盘回收时反之
CGRect keyboardFrame = [notification.userInfo[UIKeyboardFrameEndUserInfoKey] CGRectValue];
CGFloat height = keyboardFrame.size.height;
self.keyboardHeight = height;
//动画结束后self.view的frame值
CGRect selfViewFrame = self.bgView.frame;
//通过通知名字判断弹出还是回收
if
([notificationName isEqualToString:UIKeyboardWillShowNotification]) {
selfViewFrame.origin.y = SCREEN_HEIGHT - PANELHEIGHT - height;
}
else
{
selfViewFrame.origin.y = SCREEN_HEIGHT - PANELHEIGHT;
}
//取出动画时长
NSTimeInterval duration = [keyboardInfo[UIKeyboardAnimationDurationUserInfoKey] doubleValue];
//使用动画更改self.view.frame
[UIView animateWithDuration:duration animations:^{
//这里填入一些view的最终状态属性设置，即会自动产生过渡动画
self.bgView.frame = selfViewFrame;
}];
}
|
同时在show方法中显示keyWindow，进而改变界面的frame进行显示
|

10
|
- (
void
)show {
UIWindow *keyWindow = [UIApplication sharedApplication].keyWindow;
[keyWindow addSubview:self];
CGRect frame = self.bgView.frame;
if
(frame.origin.y == SCREEN_HEIGHT) {
frame.origin.y = SCREEN_HEIGHT - PANELHEIGHT;
[UIView animateWithDuration:
0.4
animations:^{
self.bgView.frame = frame;
}];
}
|
hide方法这里要考虑到键盘弹出后将self.bgView向上提高后frame的变化。

CGRect selfFrame = self.bgView.frame;
if
(selfFrame.origin.y == SCREEN_HEIGHT - PANELHEIGHT || selfFrame.origin.y == SCREEN_HEIGHT - PANELHEIGHT - self.keyboardHeight) {
[self resignFirstResponder];
selfFrame.origin.y = SCREEN_HEIGHT;
[UIView animateWithDuration:
0.4
animations:^{
self.bgView.frame = selfFrame;
} completion:^(BOOL finished) {
[IQKeyboardManager sharedManager].enable = YES;
[[NSNotificationCenter defaultCenter] removeObserver:self];
// [self.hideSucSignal sendNext:nil];
[self removeFromSuperview];
}];
}

delegate中的操作
这里首先要弄懂APPdelegate中的这几个代理方法的意思：

//App已经启动
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// Override point for customization after application launch.
return
YES;
}
//App挂起状态
- (
void
)applicationWillResignActive:(UIApplication *)application {
// Sent when the application is about to move from active to inactive state. This can occur for certain types of temporary interruptions (such as an incoming phone call or SMS message) or when the user quits the application and it begins the transition to the background state.
// Use this method to pause ongoing tasks, disable timers, and invalidate graphics rendering callbacks. Games should use this method to pause the game.
}
//APP进入后台
- (
void
)applicationDidEnterBackground:(UIApplication *)application {
// Use this method to release shared resources, save user data, invalidate timers, and store enough application state information to restore your application to its current state in case it is terminated later.
// If your application supports background execution, this method is called instead of applicationWillTerminate: when the user quits.
}
//APP将重新回到前台
- (
void
)applicationWillEnterForeground:(UIApplication *)application {
// Called as part of the transition from the background to the active state; here you can undo many of the changes made on entering the background.
}
//APP进入活跃状态
- (
void
)applicationDidBecomeActive:(UIApplication *)application {
// Restart any tasks that were paused (or not yet started) while the application was inactive. If the application was previously in the background, optionally refresh the user interface.
}
//系统时间发生改变时执行
- (
void
)applicationWillTerminate:(UIApplication *)application {
// Called when the application is about to terminate. Save data if appropriate. See also applicationDidEnterBackground:.
}
|
在上面的这些代理方法中，我们需要用到的是 applicationDidBecomeActive方法。在这个方法中我们去检查系统的粘贴板UIPasteboard *pasteboard = [UIPasteboard generalPasteboard];

if
(pasteboard.string) {
NSLog(@
"string:%@"
, pasteboard.string);
NSString *urlStr = pasteboard.string;
//如果粘贴板中的字符串包含https或http字段，我们去检查当前的控制器 如果当前的控制器是我们弹出做操作的控制器的话 isPopVC = NO;
BOOL isPopVC = NO;
UIViewController * Rootvc = self.window.rootViewController;
if
([Rootvc isKindOfClass:[UINavigationController
class
]]) {
UINavigationController * nav = (UINavigationController *)Rootvc;
UIViewController * v = [nav.viewControllers lastObject];
if
([v isKindOfClass:[UploadResCofingVC
class
]]) {
isPopVC = YES;
}
}
//如果popView == nil 并且isPopVC == NO 弹出popView弹窗视图 进行操作
if
(!self.popView && !isPopVC) {
UploadResourcesPopupView *popView = [UploadResourcesPopupView
new
];
[popView show];
self.popView = popView;
[self.popView.hideSucSignal subscribeNext:^(id x) {
@strongify(self);
self.popView = nil;
}];
}
}
}
}

总结
以上大体就是实现这个功能的基本思路，细节方面因项目而异了，比如我们需要判断当前用户的角色，当前用户是否登录，对弹窗视图后续的一些操作。当然并不完美，欢迎批评指正。

Spring框架（Spring Framework）是由Rod Johnson于2002年提出的开源Java企业级应用框架，旨在通过使用JavaBean替代传统EJB实现方式降低企业级编程开发的复杂性。该框架基于简单性、可测试性和松耦合性设计理念，提供核心容器、应用上下文、数据访问集成等模块，支持整合Hibernate、Struts等第三方框架，其适用范围不仅限于服务器端开发，绝大多数Java应用均可从中受益。
Rocky Linux（中文名：洛基）是由Gregory Kurtzer于2020年12月发起的企业级Linux发行版，作为CentOS稳定版停止维护后与RHEL（Red Hat Enterprise Linux）完全兼容的开源替代方案，由社区拥有并管理，支持x86_64、aarch64等架构。其通过重新编译RHEL源代码提供长期稳定性，采用模块化包装和SELinux安全架构，默认包含GNOME桌面环境及XFS文件系统，支持十年生命周期更新。
