获取设备类型及信息

UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad或者UI_USER_INTERFACE_IDIOM()== UIUserInterfaceIdiomPhone即可。如果要求较高可以用

+ (

NSString

*)deviceString

// 需要#import "sys/utsname.h"

uname(&systemInfo);

if

 

([deviceString isEqualToString:@

"iPhone1,2"

])    

return

 

@

"iPhone3G"

;

if

 

([deviceString isEqualToString:@

"iPhone3,1"

])    

return

 

@

"iPhone4"

;

if

 

([deviceString isEqualToString:@

"iPhone5,2"

])    

return

 

@

"iPhone5"

;

if

 

([deviceString isEqualToString:@

"iPod1,1"

])      

return

 

@

"iPodTouch 1G"

;

if

 

([deviceString isEqualToString:@

"iPod3,1"

])      

return

 

@

"iPodTouch 3G"

;

if

 

([deviceString isEqualToString:@

"iPad1,1"

])      

return

 

@

"iPad"

;

if

 

([deviceString isEqualToString:@

"iPad2,2"

])      

return

 

@

"iPad2 (GSM)"

;

if

 

([deviceString isEqualToString:@

"i386"

])         

return

 

@

"Simulator"

;

NSLog

(@

"NOTE:Unknown device type: %@"

, deviceString);

}
