如何更改titleLabel字体颜色,Xcode

Question

此代码似乎运行良好,修改我的按钮的属性,除了titleLabel字体颜色没有改变.我可以改变字体,字体大小,阴影而不是颜色.它目前显示为白色,虽然我试图将其设置为黑色.我试过了button1.titleLabel.textColor = [UIColor blackColor]; 和[button1.titleLabel setTextColor:[UIColor blackColor]]; 似乎认出了这个属性,但仍然保持白色.

[button1.titleLabel setTextColor:[UIColor blackColor]];        
[button1.titleLabel setFont:[UIFont boldSystemFontOfSize:20]];
[button1.titleLabel setShadowColor:[UIColor blackColor]];
[button1.titleLabel setShadowOffset:CGSizeMake(-1, 1)];
[button1 setTitle:@"Do it" forState:UIControlStateNormal];
button1.frame = CGRectMake(0, 0, 250, 40.0);
[myView addSubview:button1];

Answer 1

这很有效.

[button1 setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
