如何从细节制作 Mutabledictionary 以及如何将该字典添加到 MutableArray (iphone)

Question

我有一些详细信息，例如 -

对于 userone

- name-user1
纽约市

name-user2
city-oslo

现在我想使用键 name 和 location 在字典中添加这些详细信息

，我想创建一个该字典的数组，

任何人都可以告诉我该怎么办？

Answer 1

NSArray* nameArray = [NSArray arrayWithObjects:@"abc",@"asdfds",@"sdffasd",@"sadfds",@"asdfsd",nil];
NSArray* cityArray = [NSArray arrayWithObjects:@"abasdasc",@"asadws",@"asd",@"sads",@"fsd",nil];

NSMutableArray* dictArray = [NSMutableArray arrayWithCapacity:0];

for(int i = 0; i < [nameArray count]; i++)
{
    NSMutableDictionary* dictDetails = [[NSMutableDictionary dictionaryWithCapacity:0]autorelease];
    [dictDetails setValue:[nameArray objectAtIndex:i] forKey:@"Name"];
    [dictDetails setValue:[cityArray objectAtIndex:i] forKey:@"City"];

    [dictArray addObject:dictDetails];
}

NSLog(@"array is %@",dictArray);

编辑：它之前崩溃了，因为我向 dictDetails 发送了一个释放方法。相反，仅将其保留在自动释放中。

Answer 2

NSDictionary* dict1 = [NSDictionary dictionaryWithObjects:[NSArray arrayWithObjects:@"user1", @"new york", nil] forKeys:[NSArray arrayWithObjects:@"name", @"location", nil]];
NSDictionary* dict2 =[NSDictionary dictionaryWithObjects:[NSArray arrayWithObjects:@"user2", @"oslo", nil] forKeys:[NSArray arrayWithObjects:@"name", @"location", nil]]; 
NSArray* dictsArray = [NSArray arrayWithObjects:dict1, dict2, nil];
