我创建了一个按钮.标题的颜色默认为黑色.但是当我按下它时,颜色会变成蓝色,再也不会变回来,这是怎么发生的?谁能告诉我为什么?我希望按钮的标题始终保持黑色.我怎样才能做到这一点?我试过了
[button setTitleColor:[UIColor darkTextColor] forState:UIControlStateHighlighted];
[button setTitleColor:[UIColor darkTextColor] forState:UIControlStateSelected];

但是没有效果.当我在我的代码中添加它时,按钮的标题似乎总是蓝色.
代码如下.
UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[button setFrame:CGRectMake(20, 360, 280, 44)];
[button setTitle:NSLocalizedString(@"Continue", @"Label: TextLabel in Continue button") forState:UIControlStateNormal];
button.titleLabel.font = [UIFont fontWithName:@"Helvetica-Bold" size:20.0f];
button.titleLabel.textColor = [UIColor darkTextColor];
button.titleLabel.shadowColor = [UIColor blackColor];
button.autoresizingMask = UIViewAutoresizingFlexibleLeftMargin|UIViewAutoresizingFlexibleRightMargin|UIViewAutoresizingFlexibleBottomMargin|UIViewAutoresizingFlexibleWidth;
[self.view addSubview:button];
[button release];

当我删除它,并使用
button setTitleColor:(UIColor) forState:(UIControlState);

问题已经解决了!
我想格式化我,NSDate
以便昨天发生的日期将显示为"昨天".这可以使用NSDateFormatter
吗?
