这几天检查程序的泄露问题发现获取手机标识的方法存在内存泄露，查看问题出在 下面的方法
+ (NSMutableDictionary *)getKeychainQuery:(NSString *)service {
return [NSMutableDictionary dictionaryWithObjectsAndKeys:
(__bridge id)kSecClassGenericPassword,(__bridge id)kSecClass,
service, (__bridge id)kSecAttrService,
service, (__bridge id)kSecAttrAccount,
(__bridge id)kSecAttrAccessibleAfterFirstUnlock,(__bridge id)kSecAttrAccessible,
nil];
}
google很久也有发生类似问题的朋友解决方法如下：
+ (NSMutableDictionary *)getKeychainQuery:(NSString *)service {
return [NSMutableDictionary dictionaryWithObjectsAndKeys:
(__bridge_transfer id)kSecClassGenericPassword,(__bridge_transfer id)kSecClass,
service, (__bridge_transfer id)kSecAttrService,
service, (__bridge_transfer id)kSecAttrAccount,
(__bridge_transfer id)kSecAttrAccessibleAfterFirstUnlock,(__bridge_transfer id)kSecAttrAccessible,
nil];
}
然儿我这里改过后发现依然不好使这个怎么办那~~~~~最后自己摸索用下面的方法就可以，分享给大家：
static NSMutableDictionary * queryDIC;
+ (NSMutableDictionary *)getKeychainQuery:(NSString *)service {
if (!queryDIC) {
queryDIC =[NSMutableDictionary dictionaryWithObjectsAndKeys:
(__bridge_transfer id)kSecClassGenericPassword,(__bridge_transfer id)kSecClass,
service, (__bridge_transfer id)kSecAttrService,
service, (__bridge_transfer id)kSecAttrAccount,
(__bridge_transfer id)kSecAttrAccessibleAfterFirstUnlock,(__bridge_transfer id)kSecAttrAccessible,
nil];
}
return queryDIC;
}
希望对你们有用
