前言
1.大家平時(shí)在數(shù)據(jù)請(qǐng)求時(shí)候一般用的MVC模式，然后創(chuàng)建模型蚜退，要寫繁瑣的屬性。
2.當(dāng)打印模型的時(shí)候彪笼，模型也只能打印出一個(gè)地址钻注，不能看到模型里面屬性具體值，又要去重寫它的描述配猫。
- 以上內(nèi)容麻煩幅恋，然后突然一天看到個(gè)大神的簡(jiǎn)書(shū)，模仿他自己重新寫了個(gè)NSObject的分類章姓，一行代碼生成所有屬性和描述佳遣。你只是粘貼復(fù)制你Log內(nèi)容了。
- 重寫描述里面有些類型要改一下凡伊，但是json數(shù)據(jù)為空的要自己判斷零渐，如果哪位大神有其他方法還請(qǐng)告知。

步驟

大家網(wǎng)絡(luò)請(qǐng)求到的json數(shù)據(jù)一般如下:
json數(shù)據(jù).png 然后添加一個(gè)NSObject的分類系忙，里面符號(hào)一大堆腦口痛诵盼，你只需粘貼復(fù)制，代碼內(nèi)容如下:
+(void)propertyCodeWithDictionary:(NSDictionary *)dict
{
NSMutableString *strM = [NSMutableString string];
NSMutableString *descriptionHeader = [NSMutableString stringWithFormat:@"[NSString stringWithFormat:%@\"",@"@"];
NSMutableString *descriptionEnd = [NSMutableString string];
NSInteger count = [dict count];
__block NSInteger index = 0;
[dict enumerateKeysAndObjectsUsingBlock:^(id _Nonnull key,
id _Nonnull obj,
BOOL * _Nonnull stop) {
// NSLog(@"類型%@\n",[obj class]);
NSString *str;
NSString *Header;
index ++;
if ([obj isKindOfClass:NSClassFromString(@"__NSCFString")] || [obj isKindOfClass:NSClassFromString(@"NSTaggedPointerString")] || [obj isKindOfClass:NSClassFromString(@"__NSCFConstantString")]) {
str = [NSString stringWithFormat:@"@property (nonatomic, copy) NSString *%@;",key];
Header = [NSString stringWithFormat:@"%@:%@,\\n",key,@"%@"];
}
if ([obj isKindOfClass:NSClassFromString(@"__NSCFNumber")]) {
str = [NSString stringWithFormat:@"@property (nonatomic, assign) int %@;",key];
Header = [NSString stringWithFormat:@"%@:%@,\\n",key,@"%@"];
}
if ([obj isKindOfClass:NSClassFromString(@"__NSCFArray")]) {
str = [NSString stringWithFormat:@"@property (nonatomic, copy) NSArray *%@;",key];
Header = [NSString stringWithFormat:@"%@:%@,\\n",key,@"%@"];
}
if ([obj isKindOfClass:NSClassFromString(@"__NSCFDictionary")]) {
str = [NSString stringWithFormat:@"@property (nonatomic, copy) NSDictionary *%@;",key];
Header = [NSString stringWithFormat:@"%@:%@,\\n",key,@"%@"];
}
if ([obj isKindOfClass:NSClassFromString(@"__NSCFBoolean")]) {
str = [NSString stringWithFormat:@"@property (nonatomic, assign) BOOL %@;",key];
Header = [NSString stringWithFormat:@"%@:%@,\\n",key,@"%d"];
}
if ([obj isKindOfClass:(NSClassFromString(@"NSNull"))]) {
str = [NSString stringWithFormat:@"@property (nonatomic, copy) NSString *%@ (null);",key];
Header = [NSString stringWithFormat:@"%@:%@,\\n",key,@"%@"];
}
[descriptionEnd appendFormat:@"_%@,",key];
[descriptionHeader appendFormat:@"%@",Header];
[strM appendFormat:@"\n%@",str];
}];
if (count == index && count > 0) {
[descriptionHeader replaceCharactersInRange:NSMakeRange(descriptionHeader.length - 3, 3) withString:@"\","];
[descriptionEnd replaceCharactersInRange:NSMakeRange(descriptionEnd.length - 1, 1) withString:@"];"];
}
NSLog(@"\n\n*******模型所有屬性银还，自己要改下(默認(rèn)空的數(shù)據(jù)為字符串)*******%@",strM);
NSLog(@"\n\n***************重寫模型的描述粘貼復(fù)制這句***************\nreture %@%@",descriptionHeader,descriptionEnd);
}
3.最后在請(qǐng)求成功得到數(shù)據(jù)的Block里面一句話
[NSObject propertyCodeWithDictionary:<#請(qǐng)求得到的模型字典#>];
4.通過(guò)打印設(shè)置你模型的屬性风宁，還有重新描述。
5.打印模型就再也不擔(dān)心只是個(gè)地址了蛹疯。
