我有一个数组中的图像，当我在视图上显示这些图像时，它应该带有边框。如何设置边框颜色？

for(UIImage *img in imagesArray)

{

//for bordercolor

}

Answer 1

首先在 Build Phases =＆gt;中添加项目中的QuartzCore.framework框架Link Binary with Libraries =＆gt;添加按钮（+），然后在类中导入其文件，如下面的...

#import <QuartzCore/QuartzCore.h>

并使用波纹管代码设置颜色..

yourImageView.layer.borderWidth = 2.0;
yourImageView.layer.borderColor= [UIColor redColor].CGColor;

<强>更新

-(IBAction)lockword:(id)sender { 
   for (UIImage *img3 in imagesArray) { 
     UIImageView *imgview1=[[UIImageView alloc]initWithImage:img3];
    imgview1.layer.borderWidth = 2.0;
    imgview1.layer.borderColor = [UIColor redColor].CGColor;
    [imgview1 release];
    // your other code write here
    // Add this UIImageView as a subview of your view with its frame...
 } 
}

Answer 2

#import <QuartzCore/QuartzCore.h>

[imageView.layer setBorderColor: [[UIColor blackColor] CGColor]];
[imageView.layer setBorderWidth: 2.0];

Answer 3

要允许编辑imageview的边框颜色属性，您需要添加 Quartzcore框架 添加它：链接二进制文件库选项，然后在您想要更改边框颜色的位置编写以下代码：

[imageview.layer setBorderWidth:2.0]; // set the border width to any value you want so that your bordercolor would appear accordingly

[imageview.layer setBorderColor:[[UIColor blueColor].CGColor]; // set the color to whatever background color you want to set to your image
