问题 UPDATE 2 My app is crashing when presenting it modally after a user taps a button in ViewController1. In my storyboard, I have a standard present modally segue set to pop up the UINavController/UITableViewController containing the UISearchBar . That's failing every time.

For some reason transitioning via segue and then acting the UISearchBar is

问题 I'm animating a view to make it appear as it is growing from the center of the screen with a theCGAffineTransformMakeScale(), it works fine in the iOS 8 beta 4 simulator but on the 7.1 version it distorts the frame of the view. view.alpha = 0.0f; view.transform = CGAffineTransformMakeScale(0.95f, 0.95f); [UIView animateWithDuration:0.5f delay:0.0f usingSpringWithDamping:1.0f initialSpringVelocity:1 options:0 animations:^{ view.alpha = 1.0f; view.transform = CGAffineTransformMakeScale(1.0f, 1

问题 Before I try this with my approach (which I have a feeling is simplistic and too drawn out), I wanted to ask anyone if there is an easier / more direct way in Swift.

问题 I am working on an app where it starts out at a tableViewController which loads and displays data stored in a Realm database. I have it so I can create a new entry in my Realm database in a separate scene and the save button unwind segues back to the initial tableView. I current have it so the tableViewController will reload the tableView on pull down (something I Learned here, second answer down) but I would be better if the tableView would reload its self automatically upon unwind,

问题 I am showing my details in UISplitViewController in AllVisible mode. But, before that, loginViewController is there. User should login, then it will navigate UISplitViewController. I don't know how to navigate to that viewController. I am not using any UINavigationController inside my app. I have tried something, but failure.

问题 I am having a problem with quality for embedded YouTube videos in my app. I am using YTPlayerView to embed videos from YouTube. My app has 2 options: option 1 is the user can watch video with 360p quality and option 2 is 720p quality. Are these two options possible?
