navigationItem更改字体颜色/ alpha？

Question

有没有办法改变navigationItem上显示的文本的颜色或alpha？目前它的亮白色，我会（如果可能的话）喜欢将它击退一点，所以它不那么明亮。任何信息都将非常感激。

- (void)loadView {
    [[self navigationItem]setTitle:@"Location List"];
    ...
    ...

Answer 1

你需要使用setTitleView并给它一个标签 - 像这样：

UILabel *titleLabel = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 320, 30)];
titleLabel.textColor = [UIColor redColor];
titleLabel.backgroundColor = [UIColor clearColor];
titleLabel.text = @"My Title";
[self.navigationItem setTitleView:titleLabel];

Answer 2

你可以在那里放置新标签：

Answer 3

 UILabel *titleLabel = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 320, 30)];
    titleLabel.textColor = [UIColor colorWithRed:0.0/255.0 green:77.0/255.0 blue:134.0/255.0 alpha:1.0];
    titleLabel.backgroundColor = [UIColor clearColor];
    titleLabel.text = @"Videos";
    titleLabel.textAlignment = NSTextAlignmentCenter;
    titleLabel.font = [UIFont boldSystemFontOfSize:18];
    [self.navigationItem setTitleView:titleLabel];
