未设置UIButton文本颜色

Question

我正在以编程方式创建UIButton。

UIButton* button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[button setFrame:CGRectMake(0,0,160, 160)];
[button setBackgroundImage:[UIImage imageNamed:@"button.png"] forState:UIControlStateNormal];
[button setTitle:@"title" forState:UIControlStateNormal];
button.titleLabel.font = [UIFont fontWithName:@"arial" size:20];
button.titleLabel.textColor = [UIColor colorWithRed:19/255.0f green:73/255.0f blue:17/255.0f alpha:1];

除了设置textColor之外，一切都有效。有什么想法吗？

试试这个。

[button.titleLabel setFont:[UIFont fontWithName:@"arial" size:20]];
[button setTitleColor:[UIColor colorWithRed:19/255.0f green:73/255.0f blue:17/255.0f alpha:1] forState:UIControlStateNormal];

Answer 2

[button setTitleColor:[UIColor colorWithRed:19/255.0f green:73/255.0f blue:17/255.0f alpha:1] forState:UIControlStateNormal];
