objective-c - objective-c : How to use UIImage as a property in my model?

Question

我有一个Player模型:

Player.h:

#import <Foundation/Foundation.h>
@interface Player : NSObject

@property (nonatomic, strong) UIImage *image;
@property (nonatomic, strong) NSMutableArray *answers;

@end

玩家.m:

#import <Foundation/Foundation.h>
#import "Player.h"

@interface Player ()

@end

@implementation Player

- (id)init {
    if (self = [super init]) {
        self.answers = [[NSMutableArray alloc] init];
        self.image = [UIImage imageNamed:@"defaultProfileImage"]; // <-------------- error
    }
    return self;
}

@end

但是这会显示错误:使用未声明的标识符“UIImage”

如何在我的模型中使用 UIImage？

Answer 1

您需要导入

#import <UIKit/UIKit.h>

这样UIImage就被识别了
