이미지 사이즈 지정하기

이미지 사이즈를 지정하기 위해 아래와 같이 UIImage Category를 하나 만든다.

[UIImage+Extension.h]

#import <UIKit/UIKit.h>

@interface UIImage (Extension)

- (UIImage *)imageScaledToSize:(CGSize)size;

@end

[UIImage+Extension.m]

#import "UIImage+Extension.h"

@implementation UIImage (Extension)

- (UIImage *)imageScaledToSize:(CGSize)size

{

UIGraphicsBeginImageContext(size);

      [self drawInRect:CGRectMake(0, 0, size.width, size.height)];

      UIImage *image = UIGraphicsGetImageFromCurrentImageContext();

      UIGraphicsEndImageContext();

      return image;

}

@end

사용 예)

UIImage *testImg = [UIImage imageNamed:@"test.png"];

[imageView setImage:[testImg imageScaledToSize:CGSizeMake(10,10)]];
