Search 如何在NSMutableArray上搜索内容

我有一个像这样的可变数组

`

`

我想搜索

2011-05-06 00:00:00+0000

此特定日期是否在

NSMutableArray

中可用。如何在ios中执行此搜索。请帮帮我

谢谢

正确的方法是将每个

day\u id

值转换为

NSDate

对象，并调用

[NSDate compare]

查看是否相等，但是如果您确信字符串始终以这种格式出现，您可以作弊并简单地比较字符串：

NSArray *yourArray = ...;
NSString *colourId = nil;
for (NSDictionary *dict in yourArray) {
    if ([dict[@"day_id"] isEqualToString:@"2011-05-06 00:00:00 +0000"]) {
        colourId = dict[@"colour_id"];
        break;
    }
}
NSLog(@"Colour is %@", colourId);

NSArray *yourArray = ...;
NSString *colourId = nil;
for (NSDictionary *dict in yourArray) {
    if ([dict[@"day_id"] isEqualToString:@"2011-05-06 00:00:00 +0000"]) {
        colourId = dict[@"colour_id"];
        break;
    }
}
NSLog(@"Colour is %@", colourId);
