I tried the following solution with the UITextArea and I expect this will work with UIButton as well. First of all import this in your .m file – #import <QuartzCore/QuartzCore.h> and then in your loadView method add following lines yourButton.layer.cornerRadius = 10; // this value vary as per your desire yourButton.clipsToBounds = YES;
It turns out that [buttonObj sendActionsForControlEvents:UIControlEventTouchUpInside]; got me exactly what I needed, in this case. EDIT: Don’t forget to do this in the main thread, to get results similar to a user-press. For Swift 3: buttonObj.sendActions(for: .touchUpInside)
You can use -[UIButton setTitleColor:forState:] to do this. Example: Objective-C [buttonName setTitleColor:[UIColor blackColor] forState:UIControlStateNormal]; Swift 2 buttonName.setTitleColor(UIColor.blackColor(), forState: .Normal) Swift 3 buttonName.setTitleColor(UIColor.white, for: .normal) Thanks to richardchildan
Objective-C UIImage *btnImage = [UIImage imageNamed:@”image.png”]; [btnTwo setImage:btnImage forState:UIControlStateNormal]; Swift 5.1 let btnImage = UIImage(named: “image”) btnTwo.setImage(btnImage , for: .normal)
In Apple’s Accessory sample the following method is used: [button addTarget:self action:@selector(checkButtonTapped:) forControlEvents:UIControlEventTouchUpInside]; Then in touch handler touch coordinate retrieved and index path is calculated from that coordinate: – (void)checkButtonTapped:(id)sender { CGPoint buttonPosition = [sender convertPoint:CGPointZero toView:self.tableView]; NSIndexPath *indexPath = [self.tableView indexPathForRowAtPoint:buttonPosition]; if (indexPath != nil) { … } }
You can get this to work in Interface Builder (without writing any code), by using a combination of negative and positive Title and Content Insets. Update: Xcode 7 has a bug where you cannot enter negative values in the Right Inset field, but you can use the stepper control next to it to decrease the … Read more
Use the performWithoutAnimation: method and then force layout to happen immediately instead of later on. [UIView performWithoutAnimation:^{ [self.myButton setTitle:text forState:UIControlStateNormal]; [self.myButton layoutIfNeeded]; }];
In Swift 3, 4, 5: button.setTitle(“Button Title”, for: .normal) Otherwise: button.setTitle(“Button Title”, forState: UIControlState.Normal) Also an @IBOutlet has to declared for the button.
Use titleLabel instead. The font property is deprecated in iOS 3.0. It also does not work in Objective-C. titleLabel is label used for showing title on UIButton. myButton.titleLabel?.font = UIFont(name: YourfontName, size: 20) However, while setting title text you should only use setTitle:forControlState:. Do not use titleLabel to set any text for title directly.
Use button.layer.cornerRadius, button.layer.borderColor and button.layer.borderWidth. Note that borderColor requires a CGColor, so you could say (Swift 3/4): button.backgroundColor = .clear button.layer.cornerRadius = 5 button.layer.borderWidth = 1 button.layer.borderColor = UIColor.black.cgColor
