IOS Development Common Macro Summary _ios

We all know that using macros is not only convenient, but also can improve development efficiency. Here's a summary of some of the common macros in the iOS development process that will continue to be added.

Objective-c

Whether the string is empty #define KSTRINGISEMPTY (str) ([str iskindofclass:[nsnull class]] | | |-str = NIL | | [STR length] < 1? Yes:no)//array is empty #define KARRAYISEMPTY (array = = Nil | | [Array Iskindofclass:[nsnull class]] | | Array.count = = 0)//dictionary is empty #define KDICTISEMPTY (DIC) (dic = = Nil | | [DIC Iskindofclass:[nsnull class]] | | Dic.allkeys = = 0)/is empty object #define KOBJECTISEMPTY (_object) (_object = = nil \ | | [_object Iskindofclass:[nsnull class]] \ | | ([_object respondstoselector: @selector (length)] && [(NSData *) _object length] = = 0) \ | |

([_object respondstoselector: @selector (count)] && [(Nsarray *) _object count] = 0)) Get screen width and height #define kscreenwidth \ [[UIScreen mainscreen] Respondstoselector: @selector (nativebounds)]? [UIScreen mainscreen].nativebounds.size.width/[uiscreen Mainscreen].nativescale: [UIScreen MainScreen]. bounds.size.width) #define KSCREENHEIGHT \ ([[UIScreen mainscreen] Respondstoselector: @selector (nativebounds)]? [UIScreen Mainscreen].nativebounds.sizE.height/[uiscreen Mainscreen].nativescale: [UIScreen mainscreen].bounds.size.height) #define KSCREENSIZE \ ([ UIScreen Mainscreen] Respondstoselector: @selector (nativebounds)]?

 #define Kendtime NSLog (@ "Time:%f", Cfabsolutetimegetcurrent ()-start)

1. Define macro for Dimension class

DimensMacros.h
//status bar height
#define Status_bar_height
//navbar height
#define Navigation_bar_height 44
//status bar + navigation bar height
#define Status_and_navigation_height ((status_bar_height) + (navigation_bar_height))

//Screen Rect
#define SCREEN_RECT ([UIScreen mainscreen].bounds)

#define SCREEN_WIDTH ([UIScreen mainscreen]. Bounds.size.width)

#define Screen_height ([UIScreen mainscreen].bounds.size.height)

#define Content_ HEIGHT (screen_height-navigation_bar_height-status_bar_height)

//Screen Resolution
#define SCREEN_RESOLUTION ( Screen_width * screen_height * ([UIScreen mainscreen].scale))


//advertisement height
#define Banner_height 215

# Define Stylepage_height

#define Smalltv_height

#define SMALLTV_WIDTH

#define Follow_height

#define Subchannel_height 62

2. Macros that define sandbox directory files

PathMacros.h
//file directory
#define KPATHTEMP          nstemporarydirectory ()
#define Kpathdocument        [ Nssearchpathfordirectoriesindomains (NSDocumentDirectory, Nsuserdomainmask, YES) objectatindex:0]
#define Kpathcache         [Nssearchpathfordirectoriesindomains (Nscachesdirectory, Nsuserdomainmask, YES) objectAtIndex:0]

#define Kpathmagazine        [kpathdocument stringbyappendingpathcomponent:@ "Magazine"]
#define Kpathdownloadedmgzs     [kpathmagazine stringbyappendingpathcomponent:@ "downloadedmgz.plist"]
#define Kpathdownloadurls      [kpathmagazine stringbyappendingpathcomponent:@ "downloadurls.plist"]

 64:0//Get system timestamp #define GETCURENTTIME [nsstring stringwithformat:@ '%ld ', (long) [[NSDate Date] timeIntervalSince1970]]

4. Notify notification related macros
