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。
