target 'TargetName' do
pod 'LEGOImageEditor'
end

Usage

// 旋转 90°
- (void)rotate:(id)sender {
    [self.imageCropperView rotation:YES];
}

// 旋转任意角度
- (void)continueTrackingWithTouch:(CGFloat)value {
    CGFloat rotationAngle = M_PI / 180 * value;
    [self.imageCropperView setRotationAngle:rotationAngle];
}

// 修改比例 
- (void)resizeWHScale:(id)sender {
    [self.imageCropperView setResizeWHRatio:CGSizeMake(2.0, 3.0) animated:YES];
}

// 裁图
- (void)resize:(id)sender {
    [self.imageCropperView cropImageWithComplete:^(UIImage *resizeImage) {
        
    }];
}
