Question:

how to identify that particular application is installed earlier in the given iPhone or not ?

Garima P.
Answer:

we can save device code in info.plist when first time application is installed in iPhone. and we save device code because device code always change when we delete application and install again. So this can we done by saving device code permanently in info.plist file and checking that device code every time when we install application in our iPhone //get keychain value in variable NSData *passwordData = [self searchKeychainCopyMatching:@"device--code"]; //check if key chain value is empty //if keychain found then get its value in password variable. if (passwordData) { NSString *password = [[NSString alloc] initWithData:passwordData encoding:NSUTF8StringEncoding]; token=password; NSLog(@"pasword:=%@",password); } else{ //if keychain is not found...then creating keychain [self createKeychainValue:devicecode forIdentifier:@"device--code"]; token=devicecode; } here 1."device--code" is my keychain name(it can be user choice). 2."devicecode" is my device code which i get first time installing application in iPhone.
