如何獲取Objective-C中字典中每個鍵的值？

Question

我保持NSMutableDictionary pair.Now我需要爲每個it.How值從字典retrive值執行一些操作保持鍵和值。

// this is NSMutableDIctionary 
NSMutableDictionary *dictobj = [[NSMutableDictionary alloc]init]; 
// in methodA 

-(void)methodA 
{ 
    //get the value for each key and peform an operation on it. 
} 

如何進行？ plz幫助

Answer 1

for (id key in dictobj) 
{ 
    id value = [dictobj objectForKey:key]; 
    [value doSomething]; 
} 

Answer 2

我不是完全清楚你的問題是問什麼，但你可能會尋找：

for (id currentValue in [dictobj allValues]) 
{ 
    //stuff with currentValue 
} 

Answer 3

NSArray *array = [viewControllers allValues]; 
for (int i = 0; i<array.count; i++) {   
    MenuListingVC *vc = array[i]; 
    [vc tableDataReload]; 
}
