iOS 7 - 导航栏项目文本颜色

Question

我在 iOS7 上遇到导航栏项目的文本颜色问题。

在我展示一个 View Controller 之前，一切都很好，从那时起，所有导航栏项目的文本颜色都是灰色的。您对这个问题有任何经验吗？

用于呈现VC的代码:

[passcodePopover presentPopoverFromRect:CGRectMake([UIScreen mainScreen].bounds.size.width/2 ,currentWindow.frame.size.height/2,1,1)
                                     inView:currentWindow
                   permittedArrowDirections:0 animated:NO];[passcodePopover presentPopoverFromRect:CGRectMake([UIScreen mainScreen].bounds.size.width/2 ,currentWindow.frame.size.height/2,1,1)
                                     inView:currentWindow
                   permittedArrowDirections:0 animated:NO];

Answer 1

//call the below code in ViewDidLoad /It works fine in iOS7

UILabel *navLabel = [[UILabel alloc] initWithFrame:CGRectMake(0,0, 320, 100)];
navLabel.backgroundColor = [UIColor clearColor];
navLabel.text = @"Event Details";
navLabel.textColor = [UIColor whiteColor];
navLabel.shadowOffset = CGSizeMake(0, -2);
[navLabel setFont:[UIFont boldSystemFontOfSize:16]];
navLabel.textAlignment = NSTextAlignmentCenter;
self.navigationItem.titleView = navLabel;
