How to set round corners in UI images in iphone

Question

I am trying to develop an iPhone application to set the UI Image.

Answer 1

You could not set the corner of UIImage instance because it's not inherited from UIView, So you need to create an UIImageView instance by passing your UIImage.

use the below code.

UIImageView * roundedView = [[UIImageView alloc] initWithImage: [UIImage imageNamed:@"wood.jpg"]];
// Get the Layer of any view
CALayer * l = [roundedView layer];
[l setMasksToBounds:YES];
[l setCornerRadius:10.0];

Answer 2

use below code.

CALayer * l = [camBtn layer];
[l setMasksToBounds:YES];
[l setCornerRadius:10.0];

Answer 3

Get the layer of camBtn.

Setimage to that layer.

Add cornerradious to that layer.

The camBtn should be custombutton

//layer work

UIImageView * roundedView = [[UIImageView alloc] initWithImage: [UIImage imageNamed:@"wood.jpg"]];
// Get the Layer of any view
CALayer * l = [roundedView layer];
[l setMasksToBounds:YES];
[l setCornerRadius:10.0];

Answer 4

You need QuartzCore framework for this.

• Import QuartzCore Framwork
• Add #import <QuartzCore/QuartzCore.h> to your .h file

then use

UIImageView *imgViw = [[UIImageView alloc] initWithImage:img];
imgViw.layer.cornerRadius = 10.0f;
imgViw.layer.borderWidth = 1.0;//For border

Answer 5

You can use cornerRadius property

yourImageView.layer.cornerRadius = 5.0;  //change value for your need

Answer 6

set the proper radius value for this: UIImageView -> layer -> cornerRadius

Be sure to include QuartzCore.h

UIImageView* imgView = [[UIImageView alloc] initWithImage:image];
imgView.layer.cornerRadius = 15.0;

Where image is the image you wish to show. Display the above imageView to get the rounded effect

Answer 7

UIImageView *pic = [[UIImageView alloc] initWithImage: ...];
pic.layer.cornerRadius = 7.0f;
pic.layer.masksToBounds = YES;
