This is what I have : Native iOS application All game data is stored locally (levels, characters, items) I don't have any backend servers, the game is completely client side only.

问题 I would like to modify UISegmentedControl with a subclass to remove the rounded corners. I can't seem to set the cornerRadius. Making the SegmentedControl wider than the screen (and therefor "chop" off the corners) is not an option since I have 4 or 5 segments and they would then vary in size. Is there a way to do this? Thanks 回答1: You can set the width of the segments (using setWidth:forSegmentAtIndex:) so you can easily make the left and right end segments larger (say 10px larger) than the

问题 I have the below menu style layout that mimics facebook. I would like to have a dropshadow on the left side like below however the code I am using with layer shadows makes the application LAGGY. I have not been able to find a good alternative solution. Does anyone have an alternative for creating a dropshadow that does not affect application performance? [self.navController.view.layer setShadowOffset:CGSizeMake(0, 1)]; [self.navController.view.layer setShadowColor:[[UIColor darkGrayColor]

问题 Is it possible to edit values in our pList file in bundle or in our resources through code? This means that my plist file is NOT created programmatically and I want to edit its values programmatically. 回答1: In your app bundle, no: you can't write files inside your app bundle. However, you can copy the file to the Documents or Library directory of the app sandbox upon the first launch on your app, then edit the plist file from there -- wheter it was created by code or by hand is unimportant.
