如何更改狀態欄提示的文本顏色？

Question

有沒有可能在Cocoa Touch中更改導航欄提示的文本顏色（即帶有可選指令的區域）？文字可以用這個改變

[self.navigationItem setPrompt:@"My Prompt"]; 

但是這個文本的顏色呢？謝謝。

Answer 1

你可以一個UILabel添加到您的導航，並設置它的顏色

-(void) viewDidLoad { 
    UILabel *theLabel = [ [UILabel alloc ] initWithFrame:CGRectMake((self.bounds.size.width/2), 0.0, 150.0, 43.0) ]; 
theLabel.textAlignment = UITextAlignmentCenter; 
theLabel.textColor = [UIColor whiteColor]; 
theLabel.backgroundColor = [UIColor blackColor]; 
theLabel.font = [UIFont fontWithName:@"Arial Rounded MT Bold" size:(36.0)]; 



    UIView *myLabel = (make a view and add "theLabel" to it) 


    UIBarButtonItem *myBarButtonItem = [[UIBarButtonItem alloc] initWithCutomView:myLabel]; 
    [self.navigationController.navigationItem setRightBarButtonItem:myBarButtonItem animated:NO] 

}
