-(bool)checkDevice:(NSString*)name  
{  
    NSString* deviceType = [UIDevice currentDevice].model;  
    NSLog(@"deviceType = %@", deviceType);  

    NSRange range = [deviceType rangeOfString:name];  
    return range.location != NSNotFound;  
}

[cpp] view plaincopy
NSString *  nsStrIphone=@"iPhone";  
NSString *  nsStrIpod=@"iPod";

bool  bIsiPhone=false;  
bool  bIsiPod=false;  
bool  bIsiPad=false;  
bIsiPhone=[self  checkDevice:nsStrIphone];  
bIsiPod=[self checkDevice:nsStrIpod];  
bIsiPad=[self checkDevice:nsStrIpad];
