搜索NSDrray的NSArray [英] Search NSArray of NSDictionaries

问题描述

我有一个带字典的数组，
，需要通过数组搜索

I have an array with dictionaries, and need to search trough the array

并修改由对象名称找到的数组中的特定字典字典。

and modify a specific dictionary in the array found by an object name inside the dictionary.

因此，创建可变数组，字典，并向数组中添加许多字典

So , create the mutable array, dictionary , and add many dictionaries to the array

       ...{ self.bloquesArray = [[[NSMutableArray alloc] init]autorelease];  
    [self createBloqueDicto];
    [self.unBloqueDicto setObject:@"easySprite" forKey:@"Name"];
    [self.unBloqueDicto setObject:@"290" forKey:@"X"];
    [self.unBloqueDicto setObject:@"300" forKey:@"Y"];

    [self.bloquesArray addObject:self.unBloqueDicto];

}

- (void)createBloqueDicto {
self.unBloqueDicto = [[[NSMutableDictionary alloc] init] autorelease];
}

所以现在我需要更改密钥X和Y的值字典

so now I need to change the value for the key X and Y in the dictionary with

键：Name = easySprite
所以需要找到特定的字典[其他字典对名称有不同的值]

key: Name = easySprite so need to find that specific dictionary [other dictionaries have different values for Name]

我该怎么办呢？

谢谢！

推荐答案

执行以下操作以获取匹配的词典，

Do the following to get the matched dictionaries,

NSPredicate *p = [NSPredicate predicateWithFormat:@"Name = %@", @"easySprite"];
NSArray *matchedDicts = [bloquesArray filteredArrayUsingPredicate:p];

现在 matchedDicts 包含值为 @的字典easySprite用于键 @名称。从那里做其余的事情（改变X和Y）。

Now the matchedDicts contains the dictionaries with the value @"easySprite" for the key @"Name". Do the rest(changing the X and Y) from there.
