navigationItem更改字體顏色/ alpha？

Question

有沒有辦法改變navigationItem上顯示的文字的顏色或alpha？目前它的明亮的白色，我會（如果可能的話）喜歡把它稍微敲回去，以免它不那麼明亮。任何信息將不勝感激。

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

Answer 1

您需要使用setTitleView代替，並給它一個標籤 - 事情是這樣的：

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];

您可以將有新的標籤：

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];
