Is there any reason adding a UIPicker to a view might somehow rob a programatically created button of its functionality? I initially instantiated a UIButton to take me to a different view, and all was well and fine. Then I went ahead and added a UIPicker to the same view with the purpose of selecting a few key fields which could then be passed on to the view the UIButton led to. Unfortunately it seems I somehow broke my button in the process of adding the picker.
Here's the instantiation of the button:
switchToGame = [UIButton buttonWithType:UIButtonTypeRoundedRect];
switchToGame.frame = CGRectMake(140,250,100,100);
[switchToGame setTitle:@"Play God" forState:UIControlStateNormal];
[switchToGame setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
[switchToGame addTarget:self action:@selector(playGame) forControlEvents:UIControlEventTouchUpInside];
[self.view insertSubview:switchToGame atIndex:0];
The method playGame checks the fields of the picker, sends them to a shared singleton object then loads the game view as such:
Singleton *mySingleton = [Singleton sharedSingleton];
NSInteger numCellsRow = [theDataPicker selectedRowInComponent:0];
NSInteger aliveColorRow = [theDataPicker selectedRowInComponent:1];
NSInteger deadColorRow = [theDataPicker selectedRowInComponent:2];
UIColor * theAliveColor = [aliveColors objectAtIndex:aliveColorRow];
UIColor * theDeadColor = [deadColors objectAtIndex:deadColorRow];
NSInteger numCellsPerRow = [[cellRowOptions objectAtIndex:numCellsRow] intValue];
mySingleton.cellsPerRow = numCellsPerRow;
mySingleton.aliveColor = theAliveColor;
mySingleton.deadColor = theDeadColor;
[theAliveColor release];
[theDeadColor release];
GameController * viewController = [GameController alloc];
self.theViewController = viewController;
[self.view insertSubview:theViewController.view atIndex:1];
[viewController release];
I hope these stretches of code are enough for someone to point out where I went astray, as I am quite lost at the moment.
