Определение типа устройства

вы можете легко обнаружить iphone, iphone5 и iPad с условием ниже (но не iTouch! iTouch рассматривается как если бы это был iPhone с этим кодом!): –

  if([[UIDevice currentDevice]userInterfaceIdiom]==UIUserInterfaceIdiomPhone) { if ([[UIScreen mainScreen] bounds].size.height == 568) { } else { //iphone 3.5 inch screen } } else { //[ipad] } 

ОБНОВИТЬ

Вы также можете использовать MACRO или определить переменную для проверки, что iPhone5, iPhone4 или iPad, как Bellow: –

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

Пример:-

 if(isiPhone) { if (isiPhone5) { } else { //iphone 3.5 inch screen } } else { //[ipad] } 

Пожалуйста, проверьте код ниже:

Надеюсь, что это работает для вас…

 - (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; } 

Первое утверждение проверяет погоду на устройстве, которое у вас есть на iPhone 5 Screen.

Вторая проверка погоды вы используете iPad.

Третий возвращает обычный xib для iPhone 4 и ранее.

Обратите внимание: для выполнения этой работы вам нужно будет создать 3 разных XIB, все с другим суффиксом.

ViewController.xib

ViewController_568.xib

ViewController_iPad.xib

Вот куча констант, которые вы можете вставить в свой PCH-файл и использовать во всем своем приложении, что дает вам много разных вещей, которые вы можете проверить. (Широкоэкранный здесь означает iPhone 5 «более высокий» экран)

 #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 

Вы можете использовать его следующим образом:

 if(IS_IPHONE5){ // load iPhone5 code/nibs } if(IS_WIDESCREEN){ // load 4" screen stuff here } 

 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... 

А также, только для справки … iTouch:

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