Voici la fuite: code d'accès Trousseau fuite
Et voici mon code:
+(NSString *)getSecureValueForKey:(NSString *)key {
// Retrieve a value from the keychain
NSDictionary *result;
NSArray *keys = [[[NSArray alloc] initWithObjects: (NSString *) kSecClass, kSecAttrAccount, kSecReturnAttributes, nil] autorelease];
NSArray *objects = [[[NSArray alloc] initWithObjects: (NSString *) kSecClassGenericPassword, key, kCFBooleanTrue, nil] autorelease];
NSDictionary *query = [[NSDictionary alloc] initWithObjects: objects forKeys: keys];
// Check if the value was found
OSStatus status = SecItemCopyMatching((CFDictionaryRef) query, (CFTypeRef *) &result);
[query release];
if (status != noErr) {
// Value not found
return nil;
} else {
// Value was found so return it
NSString *value = (NSString *) [result objectForKey: (NSString *) kSecAttrGeneric];
return value;
[result release];
}
}
+(BOOL)storeSecureValue:(NSString *)value forKey:(NSString *)key {
// Get the existing value for the key
NSString *existingValue = [self getSecureValueForKey:key];
// Check if a value already exists for this key
OSStatus status;
if (existingValue) {
// Value already exists, so update it
NSArray *keys = [[[NSArray alloc] initWithObjects: (NSString *) kSecClass, kSecAttrAccount, nil] autorelease];
NSArray *objects = [[[NSArray alloc] initWithObjects: (NSString *) kSecClassGenericPassword, key, nil] autorelease];
NSDictionary *query = [[[NSDictionary alloc] initWithObjects: objects forKeys: keys] autorelease];
status = SecItemUpdate((CFDictionaryRef) query, (CFDictionaryRef) [NSDictionary dictionaryWithObject:value forKey: (NSString *) kSecAttrGeneric]);
} else {
// Value does not exist, so add it
NSArray *keys = [[[NSArray alloc] initWithObjects: (NSString *) kSecClass, kSecAttrAccount, kSecAttrGeneric, nil] autorelease];
NSArray *objects = [[[NSArray alloc] initWithObjects: (NSString *) kSecClassGenericPassword, key, value, nil] autorelease];
NSDictionary *query = [[[NSDictionary alloc] initWithObjects: objects forKeys: keys] autorelease];
status = SecItemAdd((CFDictionaryRef) query, NULL);
}
// Check if the value was stored
if (status != noErr) {
// Value was not stored
return false;
} else {
// Value was stored
return true;
}
}
Pouvez-vous me aider à résoudre ce problème? La fuite est chaque fois que j'accède ou stocke des données dans le trousseau. Je n'ai pas programmé sans ARC pour beaucoup de temps, et je ne peux pas suivre cette fuite!
Merci!
