Cropping ImageView in the Shape of Another ImageView - ios

Question

How can I crop my imageView into a bubble shape which I have the image in my project.

Answer 1

Following is simple code for resizing or crop image, you need to just pass height or width for image as you want:
For Get Croped Image:
UIImage *croppedImg = nil;
CGRect cropRect = CGRectMake(AS YOu Need);
croppedImg = [self croppIngimageByImageName:self.imageView.image toRect:cropRect];
Use following method that return UIImage (as You want size of image)
- (UIImage *)croppIngimageByImageName:(UIImage *)imageToCrop toRect:(CGRect)rect
{
//CGRect CropRect = CGRectMake(rect.origin.x, rect.origin.y, rect.size.width, rect.size.height+15);
CGImageRef imageRef = CGImageCreateWithImageInRect([imageToCrop CGImage], rect);
UIImage *cropped = [UIImage imageWithCGImage:imageRef];
CGImageRelease(imageRef);
return cropped;
}
Here you get Croped Image that return by above method;
OR RESIZING
And also Use following method for specific hight and width with image for Resizing UIImage:
+ (UIImage*)resizeImage:(UIImage*)image withWidth:(int)width withHeight:(int)height
{
CGSize newSize = CGSizeMake(width, height);
float widthRatio = newSize.width/image.size.width;
float heightRatio = newSize.height/image.size.height;
if(widthRatio > heightRatio)
{
newSize=CGSizeMake(image.size.width*heightRatio,image.size.height*heightRatio);
}
else
{
newSize=CGSizeMake(image.size.width*widthRatio,image.size.height*widthRatio);
}
UIGraphicsBeginImageContextWithOptions(newSize, NO, 0.0);
[image drawInRect:CGRectMake(0,0,newSize.width,newSize.height)];
UIImage* newImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
return newImage;
}
This method return NewImage, with specific size that you want.
