修改或刪除UITabbar頂部線的顏色
1.setBackgroundImage // 背景顏色
2.setShadowImage //陰影顏色
就是修改圖片顏色腋逆，以下我寫了個(gè)類目
UIImage+ImageColor.h
#import <UIKit/UIKit.h>
@interface UIImage (ImageColor)
+ (UIImage *)imageWithColor:(UIColor *)color size:(CGSize)size;
@end
UIImage+ImageColor.m
#import "UIImage+ImageColor.h"
@implementation UIImage (ImageColor)
+ (UIImage *)imageWithColor:(UIColor *)color size:(CGSize)size {
if (!color || size.width <= 0 || size.height <= 0) return nil;
CGRect rect = CGRectMake(0.0f, 0.0f, size.width, size.height);
UIGraphicsBeginImageContextWithOptions(rect.size, NO, 0);
CGContextRef context = UIGraphicsGetCurrentContext();
CGContextSetFillColorWithColor(context, color.CGColor);
CGContextFillRect(context, rect);
UIImage *image = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
return image;
}
@end
RootTabBarController.h
#import "RootTabBarController.h"
#import "UIImage+ImageColor.h"
@interface RootTabBarController ()
@end
@implementation RootTabBarController
- (void)viewDidLoad {
[super viewDidLoad];
...........
[self.tabBar setBackgroundImage:[UIImage imageWithColor:[UIColor colorWithRed:0.97 green:0.97 blue:0.99 alpha:1.00] size:CGSizeMake(self.view.frame.size.width, .5)]];
[self.tabBar setShadowImage:[UIImage imageWithColor:[UIColor colorWithRed:0.87 green:0.88 blue:0.90 alpha:1.00] size:CGSizeMake(self.view.frame.size.width, .5)]];
}
