然后Rajan的答案会做到这一点 – 2013-03-22 06:56:10

// *** To add Framework *** 
// Step 1 : Select your project From Navigation Panel on the left side 
// Step 2 : On the Right Panel you will get details, Select Summery tab if not selected 
// Step 3 : Scroll Down, you will find "Linked frameworks and Libraries", expand it. 
// Step 4 : Press "+" button to add framework, Pick "QuartzCore.framework" framework from list and ADD it. 

// Now import it to your file and do following code to add border 

// First of all add QuartzCore.framework, 
// Then import #import <QuartzCore/QuartzCore.h> your file 

UIImageView *image = [[UIImageView alloc] initWithFrame:CGRectMake(x+0, 0, 320, 460)]; 
[image setImage:[UIImage imageNamed:[NSString stringWithFormat:@"n5%d.png",i]]]; 

// Set border color and width of image 
[image.layer setBorderColor:[UIColor whiteColor].CGColor]; 
[image.layer setBorderWidth:2.0f]; 

[scr addSubview:image];

可以以这种方式做到这一点：

//you need this import 
#import <QuartzCore/QuartzCore.h> 

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

哦好吧...我刚才尝试过...但忘记导入上述头文件..silly错误...刚开始在iOS上开发更早.. – 2013-03-22 06:57:41

@BhavikKama享受派对！ – 2013-03-22 06:58:15

你可以告诉我更多关于这个边界..如果我想使用阴影和所有这一切？ – 2013-03-22 06:59:06

试试这个：

UIImageView *imageView = [UIImageView alloc]init]; 
imageView.layer.masksToBounds = YES; 
imageView.layer.borderColor = [UIColor blackColor].CGColor; 
imageView.layer.borderWidth = 1;

在导入之前#import <QuartzCore/CALayer.h>框架。

thanx这工作tooo – 2013-03-22 06:58:10

给予边框的UIImageView。

添加#import "QuartzCore/QuartzCore.h" fram工作。

imgView.layer.cornerRadius = 15.0; // set as you want. 
imgView.layer.borderColor = [UIColor lightGrayColor].CGColor; // set color as you want. 
imgView.layer.borderWidth = 1.0; // set as you want.
