作為手藝人還是多學(xué)點(diǎn)東西好,不然當(dāng)你四十歲被公司開了,或者行業(yè)不景氣了想要跳出這個(gè)坑,沒有點(diǎn)手藝咋混zzz. web幾經(jīng)在學(xué)了貌似web也要.......
不跟你多比比 下面這個(gè)分類解決的問題就是 不用手敲model.h 的代碼其實(shí)也可以不用敲model.m的代碼(相信沒幾個(gè)人是手敲的).我只是看到有提出這個(gè)需求自己 簡(jiǎn)單寫一個(gè).

關(guān)鍵點(diǎn)就是下面兩個(gè)方法
(void)createPropertyCodeWithKey:(NSString *)key andArray:(NSArray *)arr andPrdfix:(NSString *)prdfix{
dispatch_async(dispatch_get_main_queue(), ^{
NSString *classStr = [NSString stringWithFormat:@"%@%@Model",prdfix,key];
[self createPropertyCodeWithDict:arr[0] andClassStr:classStr andPrdfix:prdfix];
});
}(void)createPropertyCodeWithKey:(NSString *)key andDIC:(NSDictionary *)dic andPrdfix:(NSString *)prdfix{
dispatch_async(dispatch_get_main_queue(), ^{
NSString *classStr = [NSString stringWithFormat:@"%@%@Model",prdfix,key];
[self createPropertyCodeWithDict:dic andClassStr:classStr andPrdfix:prdfix];
});
}
這連個(gè)方法是異步主隊(duì)列 上次我記得已經(jīng)我已經(jīng)解釋過了 GCD的一些知識(shí)
我們要打印model的屬性總是希望一層一層的打印.但是在遞歸打印的時(shí)候有可能是這個(gè)樣的model模型例如
@{@"a":@"屬性1"
@"b":@"屬性2"
@"c":@"屬性3:
@"d":@{@"aa":@"我是對(duì)象"}
@"e":@"屬性4"}
我們想生成
xxxxxxxxxxx a
xxxxxxxxxxx b
xxxxxxxxxxx c
xxxxxxxxxxx d
xxxxxxxxxxx e
然后在生成
xxxxxxxxxxx aa
你看上面其實(shí)是遞歸操作 遇見value是字典 或者 數(shù)組 就有調(diào)用
自己那么我們 這個(gè)時(shí)候第一層還沒打印玩 但是又要調(diào)用自己打印
下一層我們就可以 把打印下一層的 任務(wù)放在異步主隊(duì)列 (當(dāng)然打
印調(diào)用這個(gè)方法前提是主隊(duì)列) 異步主隊(duì)列 第一不會(huì)影響 當(dāng)前線
程的任務(wù)(打印下面的屬性) 當(dāng)下面的屬性打印完了(主隊(duì)列空閑了)
就會(huì)執(zhí)行我們第一次方法主隊(duì)列的任務(wù),依次進(jìn)行下去.最后我們只
要打印臺(tái)粘貼復(fù)制
