How to delay next action in sequence until after runBlock completes? (Swift)

由 ぃ、小莉子 提交于 2019-12-25 16:52:27
问题 The duration property for moveTo isn't followed when inside a runBlock , allowing the subsequent action in a sequence to get executed immediately when it should only get executed after duration seconds. Code A (sequence properly executed): let realDest = CGPointMake(itemA.position.x, itemA.position.y) let moveAction = SKAction.moveTo(realDest, duration: 2.0) itemB.runAction(SKAction.sequence([SKAction.waitForDuration(0.5), moveAction, SKAction.runBlock { itemB.removeFromParent() }])) Code B

No matter what I do, the subview never fills superview bounds and there are few pixel gaps on the left and right. How do I

问题 I am using a SQLite database to build an iOS app. Which is the best way to store username and password: in the database or the Keychain? Also, if I store any data in database how can I make it secure like the keychain? 回答1: Keychain is better. However, we recommend that you don't save the password. You should always save the hash value and compare the hashes to see if the login is correct! 回答2: Keychain is the best option to save any kind of passwords. Use library SSKeychain which is a light

问题 Not sure exactly what I'm doing wrong here. I've listed out what my problem is and my code. Would love to get some help. Thanks! Problem: VC1 presents VC2. IBOutlets from VC1 are now nil.
