搜索nsarray的nsdictionary [英] Search nsarray of nsdictionary

问题描述

我有一个 NSArray 充满 NSDictionaries 。其中一个键的共同点是名称。我有另一个数组，填充名称。我想搜索第一个数组，如果它找到一个名称，它应该添加到第三个可变数组的字典。

解决方案

使用快速枚举，通常也是已知的as for-in loop：

  for（NSDictionary * dict in myArray）{
  
 
 
 
此外，为了比较NSString，请使用-isEqualToString：。
  if（[[dict objectForKey：myKey] isEqualToString：myString]）{
 
} 
  
 
I have an NSArray filled with NSDictionaries. One of the keys the dicts have in common is "name". I have another array, filled with names. I want to search the first array, if it finds a name it is supposed to add the dictionary to a third mutable array. The third array then contains all dictionary which names are in the name-array.
解决方案
Use "fast enumeration", commonly also known as for-in loop:
for (NSDictionary* dict in myArray) {
Also, to compare NSString's, use -isEqualToString:.
   if ([[dict objectForKey: myKey] isEqualToString:myString]) {

   }
