问题描述

How can I remove the default gradient on a UINavigationBar? What property do I set to do this?

推荐答案

您可以通过将此代码弹出来删除渐变并设置自己的纯色具有导航栏的类。您可以将UIColor更改为您需要的任何颜色。请注意，此代码需要在另一个实现之外，因此无论您使用什么.m文件，都要将它放在已在该文件中实现的类的@implmentation之前。

You can remove the gradient and set your own solid color by popping this code into the class that has the navigation bar. You can change the UIColor to whatever color you need. Note that this code needs to be outside of another implementation, so whatever .m file you put it in put it before the @implmentation of the class already implemented in that file.

@implementation UINavigationBar (UINavigationBarCategory)   
- (void)drawRect:(CGRect)rect {
UIColor *color = [UIColor blueColor];
CGContextRef context = UIGraphicsGetCurrentContext();
CGContextSetFillColor(context, CGColorGetComponents( [color CGColor]));
CGContextFillRect(context, rect);
}   
@end
