我的项目有一个UIImage类别函数,我想从另一个类调用.我正确导入图像类别的头文件,我得到项目编译没有警告.

问题是当我调用UIImage类别函数时,我看到一个无法识别的选择器错误NSInvalidArgumentException.如果我把所有东西都正确联系起来,为什么我会看到这个？

#import <UIKit/UIKit.h>

@interface UIImage (DRShare)

+ (UIImage*) imageNamed:(NSString*)name;

@end


@implementation UIImage (DRShare)

+ (UIImage*) imageNamedDR:(NSString*)name{

    CGFloat s = 1.0f;
    if([[UIScreen mainScreen] respondsToSelector:@selector(scale)]){
        s = [[UIScreen mainScreen] scale];
    }

    NSString *path = [NSString stringWithFormat:@"%@%@%@.png",kImagesPath,name,s > 1 ? @"@2x":@""];
    return [UIImage imageWithContentsOfFile:DRBUNDLE(path)];
}

@end

调用它的文件:

        backgroundView = [[UIImageView alloc] initWithImage:[UIImage imageNamedDR:@"Share Popup Background"]];
