• 需求場景：

  需要新建一個模型，在模型里要挨個復制粘貼key，確定修飾類型

• 解決思路:

  給字典建立一個分類,遍歷字典，判斷每一個值的類型，拼接上對應的修飾字符串，打印在控制臺之后復制粘貼到模型的.h文件里，節(jié)約時間

• 代碼實現(xiàn)：

@implementation NSDictionary (moreFunction)
- (void)autoCreatePropetyCode{
    
    // 模型中屬性一一對應字典的key
    // 有多少個key,則生成多少個屬性
    
    // 創(chuàng)建可變字符串用于拼接屬性
    NSMutableString *codes = [NSMutableString string];
    // 遍歷字典
    [self enumerateKeysAndObjectsUsingBlock:^(id  _Nonnull key, id  _Nonnull value, BOOL * _Nonnull stop) {
        
        
        NSString *code = nil;
        
        if ([value isKindOfClass:[NSString class]]) {
            code = [NSString stringWithFormat:@"@property (nonatomic, cppy) NSString *%@;",key];
        } else if ([value isKindOfClass:NSClassFromString(@"__NSCFBoolean")]){
            code = [NSString stringWithFormat:@"@property (nonatomic, assign) BOOL %@;",key];
        } else if ([value isKindOfClass:[NSNumber class]]) {
            code = [NSString stringWithFormat:@"@property (nonatomic, assign) NSInteger %@;",key];
        } else if ([value isKindOfClass:[NSArray class]]) {
            code = [NSString stringWithFormat:@"@property (nonatomic, strong) NSArray *%@;",key];
        } else if ([value isKindOfClass:[NSDictionary class]]) {
            code = [NSString stringWithFormat:@"@property (nonatomic, strong) NSDictionary *%@;",key];
        }
        
        // 拼接字符串
        [codes appendFormat:@"\n%@\n",code];
        
    }];
    
    // 打印屬性
    NSLog(@"%@",codes);
    
}

@end

NSDictionary *dic = @{@"title":@"123123",
                          @"name":@"123123",
                          @"sex":@"123123"
                          };
    [dic autoCreatePropetyCode];

• 控制臺輸出

@property (nonatomic, cppy) NSString *title;

@property (nonatomic, cppy) NSString *name;

@property (nonatomic, cppy) NSString *sex;
