我有一個NSMutableArray與超過150+的對象,我需要創建一個新的數組基於這個關鍵字「名稱」與輸入名稱匹配。基於密鑰與謂詞不工作排序NSMutableArray?
所以我得到這個謂詞代碼計算器
NSMutableArray *listForm=[[NSMutableArray alloc]init]; //copy Original Array
listForm=[arr valueForKey:@"data"]; //copied
NSPredicate *predicate = [NSPredicate predicateWithFormat:@"name == [c] %@", [selectedDrug valueForKey:@"name"]]; //checking name
NSLog(@"%@",[selectedDrug valueForKey:@"name"]); //my input name for matching
[listForm filteredArrayUsingPredicate:predicate];
NSLog(@"%@",listForm);//final result
現在我得到正確的結果,但與我得到額外的對象
例如像 考慮,這是我的對象
的大名單一起[{
name:"john",
location:"washington",
age:23
},{
name:"Zirad kan",
location:"iceland",
age:23
},{
name:"john",
location:"usa",
age:43
},{
name:"riya",
location:"india",
age:20
},{
name:"Rachel",
location:"netherland",
age:33
},{
name:"john Mark",
location:"washington",
age:23
},{
name:"john Doe",
location:"washington",
age:23
}]
從這我需要所有與「約翰」完全匹配的名稱
所以結果會是這樣
[{
name:"john",
location:"washington",
age:23
},{
name:"john",
location:"usa",
age:43
}]
但是,當我在上面的代碼IAM的使用越來越以此作爲最終結果
[{
name:"john",
location:"washington",
age:23
},{
name:"john",
location:"usa",
age:43
},{
name:"john Mark",
location:"washington",
age:23
},{
name:"john Doe",
location:"washington",
age:23
}]
如何刪除「李四」和「約翰·馬」像我只需要一個匹配「john」的特定文本。
