iOS-分享干货-自动生成属性的分类

• 实际开发中,我们经常利用一些小技巧提高我们的编写代码的速度,比如给一个模型写属性,我们可以利用一个分类快速帮我们打印输出我们要写的属性;
• 步骤
• 1.给NSObject写分类
• 2.提供一个类方法,方便调用(如果写成对象方法,还必须先创建一个对象才能调用,所以优先类方法)
• 3.调用分类的方法,传入字典;
• 代码:

#import 
@interface NSObject (Property)

+ (void)creatPropertyCodeWithDictionary:(NSDictionary *)dict;
@end

#import "NSObject+Property.h"

@implementation NSObject (Property)

+ (void)creatPropertyCodeWithDictionary:(NSDictionary *)dict
{
     NSMutableString *strM = [NSMutableString string];
    [dict enumerateKeysAndObjectsUsingBlock:^(id  _Nonnull propertyName, id  _Nonnull value, BOOL * _Nonnull stop) {
       
        NSString *code;
        if ([value isKindOfClass:NSClassFromString(@"__NSCFNumber")]) {
            code = [NSString stringWithFormat:@"@property (nonatomic,assign) int %@;",propertyName];
        }else if ([value isKindOfClass:NSClassFromString(@"__NSCFArray")]) {
            code = [NSString stringWithFormat:@"@property (nonatomic,strong) NSArray *%@;",propertyName];
        }else if ([value isKindOfClass:NSClassFromString(@"__NSCFString")]) {
            code = [NSString stringWithFormat:@"@property (nonatomic,strong) NSString *%@;",propertyName];
        }else if ([value isKindOfClass:NSClassFromString(@"__NSCFDictionary")]) {
            code = [NSString stringWithFormat:@"@property (nonatomic,strong) NSDictionary *%@;",propertyName];
        }else if ([value isKindOfClass:NSClassFromString(@"__NSCFBoolean")]) {
            code = [NSString stringWithFormat:@"@property (nonatomic,assign) BOOL %@;",propertyName];
        };
        
        [strM appendFormat:@"\n%@\n",code];
    }];
    NSLog(@"%@",strM);
}
@end
