以上为ViewController中的代码

FlagView中的代码：

#import 
     
      #import "CZFlag.h"@interface FlagView : UIView@property (weak, nonatomic) IBOutlet UIImageView *iconView;@property (weak, nonatomic) IBOutlet UILabel *nameView;@property (nonatomic,  strong) CZFlag *flag;+ (instancetype )flagView;@end//.m中#import "FlagView.h"@implementation FlagView+ (instancetype )flagView{    return [[[NSBundle mainBundle] loadNibNamed:@"FlagView" owner:nil options:nil] lastObject];}- (void)setFlag:(CZFlag *)flag{    self.nameView.text = flag.name;    self.iconView.image = [UIImage imageNamed:flag.icon];}@end
     

CZFlag中

#import 
     
      @interface CZFlag : NSObject@property (nonatomic, copy)NSString *name;@property (nonatomic, copy)NSString *icon;+ (NSArray *)flagList;- (instancetype)initWithDic:(NSDictionary *)dic;+ (instancetype)flagWithDic:(NSDictionary *)dic;@end//.m中#import "CZFlag.h"@implementation CZFlag- (instancetype)initWithDic:(NSDictionary *)dic{    if (self = [super init]) {        [self setValuesForKeysWithDictionary:dic];    }     return self;}+ (instancetype)flagWithDic:(NSDictionary *)dic{  CZFlag *flag =  [[CZFlag alloc] initWithDic:dic];    return flag;}+ (NSArray *)flagList{    NSString *path = [[NSBundle mainBundle] pathForResource:@"flags" ofType:@"plist"];    NSMutableArray *tmpArray = [NSMutableArray array];    NSArray *dicArray = [NSArray arrayWithContentsOfFile:path];    for (NSDictionary *dic in dicArray) {     CZFlag *flag =  [CZFlag flagWithDic:dic];        [tmpArray addObject:flag];    }    return tmpArray;}@end
     

效果如下
