iOS 字典自动生成模型

在实际开发中，我们经常需要根据字典来建模型。每次都打那么一串代码，想想也是挺恶心的。可以自己给NSDictionary写一个分类，进行属性生成。

NSDictionary+Property.h

#import <Foundation/Foundation.h>

@interface NSDictionary (Property)

- (void)createPropertyCode;

@end

NSDictionary+Property.m

#import "NSDictionary+Property.h"

@implementation NSDictionary (Property)
// isKindOfClass:判断是否是当前类或者子类
// 生成属性代码 => 根据字典中所有key
- (void)createPropertyCode
{
    NSMutableString *codes = [NSMutableString string];
    // 遍历字典
    [self enumerateKeysAndObjectsUsingBlock:^(id  _Nonnull key, id  _Nonnull value, BOOL * _Nonnull stop) {
        
        NSString *code;
        if ([value isKindOfClass:[NSString class]]) {
            code = [NSString stringWithFormat:@"@property (nonatomic, strong) 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];
        }

        [codes appendFormat:@"\n%@\n",code];        
    }];
    NSLog(@"%@",codes);
}
