C#小心匿名辦法形成的變量同享實例剖析。本站提示廣大學習愛好者:(C#小心匿名辦法形成的變量同享實例剖析)文章只能為提供參考,不一定能成為您想要的結果。以下是C#小心匿名辦法形成的變量同享實例剖析正文
話不多說,直接看示例代碼
```
// UIImageView *imageView = [[UIImageView alloc]initWithFrame:CGRectMake(0, 0, kScreenW, tabBarHeight + 5)];
// [imageView setImage:[self createImageWithColor:[UIColor clearColor]]];
// [imageView setContentMode:UIViewContentModeScaleToFill];
// [self.tabBar insertSubview:imageView atIndex:0];
//籠罩原生Tabbar的上橫線
// [[UITabBar appearance] setShadowImage:[self createImageWithColor:[UIColor clearColor]]];
//配景圖片為通明色
// [[UITabBar appearance] setBackgroundImage:[self createImageWithColor:[UIColor clearColor]]];
self.tabBar.backgroundColor = [UIColor clearColor];
//設置為半通明
self.tabBarController.tabBar.translucent = YES;
```
```
-(UIImage*) createImageWithColor:(UIColor*) color
{
CGRect rect=CGRectMake(0.0f, 0.0f, 1.0f, 1.0f);
UIGraphicsBeginImageContext(rect.size);
CGContextRef context = UIGraphicsGetCurrentContext();
CGContextSetFillColorWithColor(context, [color CGColor]);
CGContextFillRect(context, rect);
UIImage *theImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
return theImage;
}
```
以上就是在IOS完成自界說通明配景的tabbar的全體內容,願望這篇文章對年夜家能有所贊助。
