Is it possible to get continuous key presses?
I'm using keyCommands: to intercept the arrows keys being pressed on an external keyboard, but I only get 1 call per press. I would love to get either multiple calls every X milliseconds as long as the key is held down, or calls when the key is pressed and when it’s released.
Here's my code:
- (NSArray *)keyCommands
{
UIKeyCommand *upArrow = [UIKeyCommand keyCommandWithInput:UIKeyInputUpArrow
modifierFlags:0
action:@selector(upArrow:)];
UIKeyCommand *downArrow = [UIKeyCommand keyCommandWithInput:UIKeyInputDownArrow
modifierFlags:0
action:@selector(downArrow:)];
UIKeyCommand *leftArrow = [UIKeyCommand keyCommandWithInput:UIKeyInputLeftArrow
modifierFlags:0
action:@selector(leftArrow:)];
UIKeyCommand *rightArrow = [UIKeyCommand keyCommandWithInput:UIKeyInputRightArrow
modifierFlags:0
action:@selector(rightArrow:)];
UIKeyCommand *leftArrowCmd = [UIKeyCommand keyCommandWithInput:UIKeyInputLeftArrow
modifierFlags:UIKeyModifierCommand
action:@selector(leftArrowCmd:)];
UIKeyCommand *rightArrowCmd = [UIKeyCommand keyCommandWithInput:UIKeyInputRightArrow
modifierFlags:UIKeyModifierCommand
action:@selector(rightArrowCmd:)];
UIKeyCommand *lCmd = [UIKeyCommand keyCommandWithInput:@"l"
modifierFlags:UIKeyModifierCommand
action:@selector(lCmd:)];
UIKeyCommand *rCmd = [UIKeyCommand keyCommandWithInput:@"r"
modifierFlags:UIKeyModifierCommand
action:@selector(rCmd:)];
UIKeyCommand *mCmd = [UIKeyCommand keyCommandWithInput:@"m"
modifierFlags:UIKeyModifierCommand
action:@selector(mCmd:)];
return @[upArrow, downArrow, leftArrow, rightArrow, leftArrowCmd, rightArrowCmd, lCmd, rCmd, mCmd];
}
Seems that this is indeed not possible in iOS 7.
