[button addTarget:self action:@selector(aMethod:)
forControlEvents:UIControlEventTouchDown];
[button setTitle:@"Show View" forState:UIControlStateNormal];
button.frame = CGRectMake(80.0, 210.0, 160.0, 40.0);
[view addSubview:button];

如何更改标题颜色？

Answer 1

你可以-[UIButton setTitleColor:forState:]用来做这件事.

例:

Objective-C的

[buttonName setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];

buttonName.setTitleColor(UIColor.blackColor(), forState: .Normal)

斯威夫特3

buttonName.setTitleColor(UIColor.white, for: .normal)

Answer 2

您创建的UIButton添加了ViewController,下面的实例方法来改变UIFont,tintColor和TextColor的UIButton

Objective-C的

 buttonName.titleLabel.font = [UIFont fontWithName:@"LuzSans-Book" size:15];
 buttonName.tintColor = [UIColor purpleColor];
 [buttonName setTitleColor:[UIColor purpleColor] forState:UIControlStateNormal];

迅速

buttonName.titleLabel.font = UIFont(name: "LuzSans-Book", size: 15)
buttonName.tintColor = UIColor.purpleColor()
buttonName.setTitleColor(UIColor.purpleColor(), forState: .Normal)

Swift3

buttonName.titleLabel?.font = UIFont(name: "LuzSans-Book", size: 15)
buttonName.tintColor = UIColor.purple
buttonName.setTitleColor(UIColor.purple, for: .normal)
