BUILD A SIMPLE IPHONE APP, MAKING IT PRETTY = EXTRA CREDIT
Can someone kindly tell me how to complete the following task:
"Delete the button from the Storyboard and try to add it programmatically within the viewDidLoad method.
Set an image for the button using its background image property and then set the title text. This should allow you to change the text of your button without having to change the image."
When I attempted it by button when to the top and when I pressed the button nothing happened.
Hi im having a similar problem to this..
I have tried searching and have so far got this:
UIImage *button = [UIImage imageNamed:@"PredictButton.png"]; UIImage *buttonOff = [UIImage imageNamed:@"PredictButtonOff.png"]; UIImageView *buttonView = [[UIImageView alloc] initWithImage:button highlightedImage:buttonOff]; buttonView.userInteractionEnabled = YES; UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(imageTapped)]; [buttonView addGestureRecognizer:tap]; buttonView.frame = CGRectMake(20, 380, 280, 40); [self.view insertSubview:(buttonView) atIndex:0];
(*Also need to find out how it will link to change the predictionArray and change the predictionLabel.text)
Im stuck where to go next as trying to link the touchGesture so it enables the highlighted version?
To be honest i think ive made things a little too complicated already...
