iOS 開發：獲取狀態欄、導航欄、tabBar 的高度

https://blog.stormbirds.cn/articles/2019/12/17/1576569283226.html

状态栏、导航栏和 tabbar 高度（pt）

iPhone型号	状态栏	状态栏	导航栏	导航栏	tabBar	tabBar
iPhone型号	竖屏	横屏	竖屏	横屏	竖屏	横屏
5s/SE/6/6s/7/8(iOS10)	20	20	44	32	49	49
5s/SE/6/6s/7/8(iOS11)	20	20	44	32	49	32
6/6s/7/8 Plus	20	20	44	44	49	49
X/XS	44	0	44	32	83(49+34)	53(32+21)
XR/XS Max	44	0	44	44	83(49+34)	70(49+21)

（对于原生TabBar，iPhoneX会在其底部增加34pt，为的是不影响所谓的HomeBar，从而整个TabBar的高度变为49+34=83pt）

bar	高度总结
状态栏	全面屏iPhone竖屏44，全面屏iPhone横屏0，普通iPhone为20
导航栏	屏幕宽度小于400的设备横屏时为32，其余情况为44
tabbar	屏幕宽度小于400的设备在iOS11以上的系统横屏时为32，其余情况为49
安全区域	竖屏34，横屏21

iPad型号	状态栏	导航栏	tabBar
普通iPad(iOS11)	20	44	49
普通iPad(iOS12)	20	50	50
全面屏iPad	24	50	65(50+15)

获取状态栏、导航栏、tabBar高度

//获取状态栏的高度
CGFloat statusHeight = [[UIApplication sharedApplication] statusBarFrame].size.height;
NSLog(@"状态栏高度：%f",statusHeight);

//获取导航栏的高度
CGFloat navHeight = self.navigationController.navigationBar.frame.size.height;
NSLog(@"导航栏高度：%f",navHeight);

//获取tabBar的高度
//1.在tabBarController中使用（你的继承自UITabBarController的VC）
CGFloat tabBarHeight = self.tabBar.frame.size.height;
NSLog(@"tabBar高度：%f",tabBarHeight);
//2.在非tabBarController中使用
UITabBarController *tabBarVC = [[UITabBarController alloc] init];//(这儿取你当前tabBarVC的实例)
CGFloat tabBarHeight = tabBarVC.tabBar.frame.size.height;
NSLog(@"tabBar高度：%f",tabBarHeight);

定义状态栏、导航栏、tabBar高度

#define kIs_iphone (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone)
#define kIs_iPhoneX kScreenWidth >=375.0f && kScreenHeight >=812.0f&& kIs_iphone
    
/*状态栏高度*/
#define kStatusBarHeight (CGFloat)(kIs_iPhoneX?(44.0):(20.0))
/*导航栏高度*/
#define kNavBarHeight (44)
/*状态栏和导航栏总高度*/
#define kNavBarAndStatusBarHeight (CGFloat)(kIs_iPhoneX?(88.0):(64.0))
/*TabBar高度*/
#define kTabBarHeight (CGFloat)(kIs_iPhoneX?(49.0 + 34.0):(49.0))
/*顶部安全区域远离高度*/
#define kTopBarSafeHeight (CGFloat)(kIs_iPhoneX?(44.0):(0))
 /*底部安全区域远离高度*/
#define kBottomSafeHeight (CGFloat)(kIs_iPhoneX?(34.0):(0))
/*iPhoneX的状态栏高度差值*/
#define kTopBarDifHeight (CGFloat)(kIs_iPhoneX?(24.0):(0))
/*导航条和Tabbar总高度*/
#define kNavAndTabHeight (kNavBarAndStatusBarHeight + kTabBarHeight)

还在用宏定义 “iphoneX” 判断安全区域 (safe area) 吗? 下文教學改用 Safe Area

<iOS螢幕適配> iPhoneX SafeArea - 安全區域宏定义

https://www.itread01.com/content/1541935567.html

/** 裝置螢幕寬度 */

#define LCLScreenWidth [[UIScreen mainScreen] bounds].size.width

/** 裝置螢幕高度 */

#define LCLScreenHeight [[UIScreen mainScreen] bounds].size.height

/** iPhoneX判斷 */

#define LCLIsIphoneX (CGSizeEqualToSize(CGSizeMake(375.f, 812.f), [UIScreen mainScreen].bounds.size) || CGSizeEqualToSize(CGSizeMake(812.f, 375.f), [UIScreen mainScreen].bounds.size))

/** 狀態列高度 */

#define LCL_StatusBar_Height ((LCLIsIphoneX) ? 44 : 20)

/** 導航欄高度 */

#define LCL_NavBar_Height ((LCLIsIphoneX) ? 88 : 64)

/** 標籤欄高度 */

#define LCL_TabBar_Height ((LCLIsIphoneX) ? 83 : 49)

/** 底部橫條高度 */

#define LCL_HomeIndicator_Height ((LCLIsIphoneX) ? 34 : 0)

適配iPhone X相關的坑，總的來說有兩類坑，一個是導航欄+狀態列的高度發生了變化，一個是一些沒有實現實現-tableView: viewForHeaderInSection:和-tableView: viewForFooterInSection:等代理方法的UITableView會出錯位的問題。

iOS 開發：導航欄顯示和隱藏的坑

混合使用 UINavigationController 和 UITabBarController 後，

如果有些畫面需要隱藏『導航欄』，而有些畫面又需要顯示『導航欄』，

動畫切換過程的瑕疵，如何解決：

以南非為例，談談落後指標、先行指標等

https://www.storm.mg/investreview2020/article/2907252

我們先用落後指標來檢視 , 南非的狀況

落後指標：失業率

為什麼一開場先用落後指標，無非是告訴大家，這指標落後於基本面，是一個很好的檢視方式！

如果過去政府有對經濟做出貢獻與努力，最終失業率就會下降

但是很遺憾的，這個南非政府似乎無能改善！

下圖為失業率：數據是29%，截至 2020 年的資料，是近十年最高了

落後的指標看過去是否能夠改善，先行的指標看未來是否有機會改善

先行指標：製造業PMI

目前的數據是45.7，這是全球前幾名的低！

PMI 低於50就是進入衰退的前兆，45.7這個數字也預告南非未來也不太樂觀！

南非製造業PMI 低於50。

什麼樣的環境造成南非這麼慘呢？

看一個國家就至少也要看他的基礎建設是否完善，

南非的罩門在哪？在於電力不足？因此百業蕭條。

如果一個國家缺電，您想能投資什麼產業？

半導體？不可能。生產線一停電要損失多少？

製造業？產品做一半停電怎麼辦？

所以最後南非可以依賴的就是礦業，一直都是礦業。

也因為南非電力不穩定，甚至導致國家信評可能被降低到更低的垃圾等級，簡稱垃圾中的垃圾 ......

再看看影響南非幣的主要外部因素：美元

美元強，南非幣弱；反之...

南非幣的經常帳：自從2008年以來沒有正數

因此國家缺錢怎麼辦？只好借外債了。以債養債這個國家很慘！

債務占國家 GDP 比重也隨著外債的增加持續高漲！

結論：

1. 南非從基本面來看，離好轉還有很長遠的距離。

2. 如果基本面要轉好，至少南非的電力問題要搞定，而南非電力如果政府不救，就是快要破產的公司了，一個國家搞成這樣不容易！

3. 南非幣可以投資嗎？如果您很喜歡投機的話可以考慮（但是光換匯成本就超過 3%）

4. 南非的展望：南非是新興市場中前五名脆弱的，只要美元轉強，那麼南非可能就是受害最嚴重的國家之一。

開發 iOS，PCH 檔案的配置及使用

https://www.itread01.com/p/398294.html

在 Xcode 6 之前，建立一個新工程時 Xcode 會在 Supporting files 資料夾下面自動建立一個「工程名-Prefix.pch」檔案，這也是一個頭檔案，pch 標頭檔案的內容能被專案中的其他所有原始檔共享和訪問。是一個預編譯檔案。

PCH 檔案的作用

1. 用來包含一些使用頻率較高的標頭檔案

2. 存放一些全域性的巨集

3. 因為是預編譯檔案，會增加編譯時間，所以在 Xcode 6 以後，蘋果為了避免濫用 pch 檔案，不再自動生成。

在 PCH 中定義的巨集會自動新增到所有的檔案中，所以新增的時候要特別注意，一定要區分 C 檔案和 OC 檔案，如果不區分，把 OC 巨集用的內碼表新增到 C 檔案中，C 檔案無法識別 OC 中的框架就會報錯。

詳見課程影片：

https://www.youtube.com/watch?v=PI3hbyaYT2s&list=PLzKtnppOmiXAlARyp-aRjP0e-RsWiS4UW&index=12

還有如何區分 Debug 和 Release 等細節

建立一個import所有巨集相關的檔案Macros.h
Macros.h
#import "UtilsMacros.h"
#import "APIStringMacros.h"
#import "DimensMacros.h"
#import "NotificationMacros.h"
#import "SharePlatformMacros.h"
#import "StringMacros.h"
#import "UserBehaviorMacros.h"
#import "PathMacros.h"
在xcode專案的pch檔案中，匯入Macros.h檔案
XcodeProjectName-Prefix.pch
#ifdef __OBJC__
#import <UIKit/UIKit.h>
#import <Foundation/Foundation.h>
#import "Macros.h"
