use dispatch_after: double delayInSeconds = 2.0; dispatch_time_t popTime = dispatch_time(DISPATCH_TIME_NOW, delayInSeconds * NSEC_PER_SEC); dispatch_after(popTime, dispatch_get_main_queue(), ^(void){ //code to be executed on the main queue after delay [self MoveSomethingFrom:from To:to]; }); EDIT 2015: For Swift, i recommend using this small helper method: dispatch_after – GCD in swift?
You can get an indexed element from an array returned with // Get the 5th element matching the .dfdf css selector element.all(by.css(‘.dfdf’)).get(4).sendKeys(‘foo’);
you need @objc to expose a private method to objc runtime @objc private func buttonDidTap(button:UIButton!) { println(button.char) } From Xcode6 beta4 release notes Declarations marked private are not exposed to the Objective-C runtime if not otherwise annotated. IB outlets, IB actions, and Core Data managed properties remain exposed to Objective-C whatever their access level. If …
This is a solution based on the runtime C functions: class_copyMethodList returns a list of class methods given a Class object obtainable from an object. #import <objc/runtime.h> [..] SomeClass * t = [[SomeClass alloc] init]; int i=0; unsigned int mc = 0; Method * mlist = class_copyMethodList(object_getClass(t), &mc); NSLog(@”%d methods”, mc); for(i=0;i<mc;i++) NSLog(@”Method no #%d: …
Set clickable, focusable, focusableInTouchMode to true in all elements of RecyclerView “list”.
In the case that you cannot alter the target-method signature to accept a NSNumber in place of a BOOL you can use NSInvocation instead of performSelector: MyTargetClass* myTargetObject; BOOL myBoolValue = YES; // or NO NSMethodSignature* signature = [[myTargetObject class] instanceMethodSignatureForSelector: @selector( myMethodTakingBool: )]; NSInvocation* invocation = [NSInvocation invocationWithMethodSignature: signature]; [invocation setTarget: myTargetObject]; [invocation setSelector: …
Not directly, but some workarounds are possible. Take a look at the following example. /// Target-Action helper. final class Action: NSObject { private let _action: () -> () init(action: @escaping () -> ()) { _action = action super.init() } @objc func action() { _action() } } let action1 = Action { print(“action1 triggered”) } let …
Selector(“tap:”) should now be written as #selector(tap(gestureReconizer:)) Also, you should declare tap as func tap(_ gestureRecognizer: UITapGestureRecognizer) as per the new Swift API Guidelines in which case your selector would then become #selector(tap(_:)).
I figured out how to get the tag, which was the most important part of the question for me. Since the gesture is the sender, I figured out the the view it is attached to is sent along with it: [(UIGestureRecognizer *)sender view].tag I am still curious if anyone can tell me how to send …
The problem here isn’t passing a selector to a method, per se, but passing a selector where an object is expected. To pass a non-object value as an object, you can use NSValue. In this case, you’ll need to create a method that accepts an NSValue and retrieves the appropriate selector. Here’s an example implementation: …
