檢測iOS設備類型

Question

在我的應用程序（用Objective-C編寫）中，如何檢測設備是iPhone，iPad還是iPhone5？

if([[UIDevice currentDevice]userInterfaceIdiom] == UIUserInterfaceIdiomPhone) {
    // [iphone] or [itouch]
} else {
    // [ipad]
}

Answer 1

您可以在以下條件下輕松檢測iphone，iphone5和iPad（但不是iTouch！iTouch被視為具有此代碼的iPhone！）： -

 if([[UIDevice currentDevice]userInterfaceIdiom]==UIUserInterfaceIdiomPhone)
 {
     if ([[UIScreen mainScreen] bounds].size.height == 568)
     {


     }
     else
     {
         //iphone 3.5 inch screen
     }
 }
 else
 {
        //[ipad]
 }

UPDATE

您也可以使用MACRO或定義變量來檢查iPhone5，iPhone4或iPad如Bellow： -

#define isiPhone5  ([[UIScreen mainScreen] bounds].size.height == 568)?TRUE:FALSE
#define isiPhone  (UI_USER_INTERFACE_IDIOM() == 0)?TRUE:FALSE

例：-

if(isiPhone)
     {
         if (isiPhone5)
         {


         }
         else
         {
             //iphone 3.5 inch screen
         }
     }
     else
     {
            //[ipad]
     }

請檢查以下代碼：

Answer 3

- (id)initWithNibName:(NSString *)nibName bundle:(NSBundle *)nibBundle {
if ([[ UIScreen mainScreen ] bounds ].size.height == 568 ) {
nibName = [NSString stringWithFormat:@"%@_568", nibName];

}

if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) {
nibName = [NSString stringWithFormat:@"%@_iPad", nibName]; {

}

if (self = [super initWithNibName:nibName bundle:nibBundle]) {
}

return self;
}

第一個語句檢查您擁有iPhone 5屏幕的設備的天氣。

第二次檢查天氣你正在使用iPad。

第三個返回iPhone 4s和之前的正常xib。

請注意，要完成這項工作，您必須創建3個不同的XIB，所有XIB都有不同的后綴。

ViewController.xib

ViewController_568.xib

ViewController_iPad.xib

Answer 4

以下是一些常量，您可以將這些常量粘貼到PCH文件中，並在整個應用程序中使用，這些常量可以為您提供許多可以測試的不同內容。 （這里的寬屏意味着iPhone 5“更高”的屏幕）

#ifndef IS_WIDESCREEN
#define IS_WIDESCREEN   (fabs((double)[[UIScreen mainScreen] bounds].size.height - (double)568) < DBL_EPSILON)
#endif

#ifndef IS_IPHONE
#define IS_IPHONE       ([[[UIDevice currentDevice] model] isEqualToString:@"iPhone"])
#endif

#ifndef IS_IPOD
#define IS_IPOD         ([[[UIDevice currentDevice] model] isEqualToString:@"iPod touch"])
#endif

#ifndef IS_IPAD
#define IS_IPAD         ([[[UIDevice currentDevice] model] isEqualToString:@"iPad"])
#endif

#ifndef IS_IPHONE5
#define IS_IPHONE5      (IS_WIDESCREEN && IS_IPHONE)
#endif

#ifndef IS_IPOD5
#define IS_IPOD5        (IS_WIDESCREEN && IS_IPOD)
#endif

你可以像這樣使用它：

if(IS_IPHONE5){
    // load iPhone5 code/nibs
}

if(IS_WIDESCREEN){
    // load 4" screen stuff here
}

Answer 5

if ([[UIDevice currentDevice].model hasPrefix:@"iPhone"]) {//iPhone... (not iTouch or iPad)

if ([[UIDevice currentDevice].model hasPrefix:@"iPad"]) {//iPad...

if (([[UIDevice currentDevice].model hasPrefix:@"iPhone"]) && ([UIScreen mainScreen]bounds].size.height == 568)) {//iPhone5...

而且，僅供參考...... iTouch是這樣的：

if ([[UIDevice currentDevice].model hasPrefix:@"iPod"]) {//iTouch
