问题 I have some constraints that a shuffle around during an animation. After upgrading to XCode9 I tried to make some tweaks, and the editor seems to no longer allow me to add constraints to an constraint collection IBOutlet. I even created a new project and tried to make a simple outlet collection and ran into the same issue. Here's a short video of what I'm talking about: I've tried the usual things of deleting derived data, restarting xcode, creating new xibs, praying to the xcode gods...etc.

问题 Does anybody know how to set the title of each individual button in an array of buttons using an IBOutletCollection? This is what I have tried, but the code sets the title of all the buttons. I have connected the outlet to the buttons and set their respective tags. .h file @property (nonatomic, retain) IBOutletCollection(UIButton) NSArray *buttonCollection; .m file - (IBAction)switchAction:(id)sender { for (UIButton *btn in buttonCollection) { if (btn.tag == 0) { [btn setTitle:@"1st Button"

Renaming class causes IBOutlet connection to fail

由 泄露秘密 提交于 2019-12-13 15:24:12
问题 I renamed a class, which happened to have an outlet connection to a label called mainLabel in a storyboard file. When I run my program, it crashes and gives me the error: "this class is not key value coding-compliant for the key mainLabel". Other SO answers have shown this to be caused by a bad outlet connection, so I removed the connection and removed any lose ends. When trying to reconnect the label to an outlet in my code, I get the error Could not insert new outlet connection: Could not

问题 I have 30 buttons in one view in Interface Builder. Each has a different tag between 100001 and 100030. I've found it easy to use the same action for each button, passing along the tag for each one when pressed and using code to decide which level to load. I want to connect all the buttons to a single IBOutlet, but have each button load a different image based on the user's saved data and the button's tag. How do I do this? 回答1: Use IBOutletCollection to add an outlet collection to your view

Just so I don't have so many declarations in my header file. 回答1: It is possible, it’s called outlet collection . This is the way to define an outlet collection: @property(retain) IBOutletCollection(UIImageView) NSArray *images;
