有时候后台在偷懒的的时候 给你返回NULL 那么问题就来了。。。
MySelfWorkInfoModel.h
#import <Foundation/Foundation.h>
@interface MySelfWorkInfoModel : NSObject
@property (nonatomic ,assign) NSUInteger userInfoId;
@property (nonatomic ,strong) NSString *headPicAdd;
@property (nonatomic ,strong) NSString *nick;
@property (nonatomic ,assign) NSInteger todayWorkTime;
@property (nonatomic ,strong) NSString *workLong;
@property (nonatomic ,assign) NSInteger successOrderNum;+ (instancetype)creatRankingTotalModelWith:(NSDictionary *)dict;
@end
MySelfWorkInfoModel.m
#import "MySelfWorkInfoModel.h"
@implementation MySelfWorkInfoModel
- (instancetype)initWithDict:(NSDictionary *)dict {
if (self = [super init]) {
[self setValuesForKeysWithDictionary:dict];
}
return self;
}
+ (instancetype)creatRankingTotalModelWith:(NSDictionary *)dict {
MySelfWorkInfoModel *model = [[self alloc] initWithDict:dict];
return model;
}
- (void)setValue:(id)value forKey:(NSString *)key {
value = [self setNoNull:value];
[super setValue:value forKey:key];
}
//只需要下面这段代码搞定你所遇到的问题
- (id) setNoNull:(id)aValue{
if (aValue == nil) {
aValue = @"";//为null时，直接赋空
} else if ((NSNull *)aValue == [NSNull null]) {
aValue = @"";
if ([aValue isEqual:nil]) {
aValue = @"";
}
}
return aValue;
}
- (void)setValue:(id)value forUndefinedKey:(NSString *)key {
}
@end
