ios - NSMutableArray 中的 NSDictionary (iOS)

Question

<分区>

Answer 1

你的错误在这里:

NSMutableArray *array = [[NSMutableArray alloc] init];
[array setValue:dictionary forKey:@"some_key"];

------------^^^^^

您正在将其设置到数组中。

试试这个:

NSDictionary *dictionary = [[NSDictionary alloc] initWithObjectsAndKeys:@"another_value", @"another_key", nil];
NSDictionary *outDict=[[NSDictionary alloc]initWithObjectsAndKeys:dictionary,@"some_key", nil];
NSMutableArray *array = [[NSMutableArray alloc] initWithObjects:outDict, nil];

在新文字中:

NSDictionary *d=@{@"another_key":@"another_value"};
NSDictionary *c=@{@"some_key":d};
NSArray *array=@[c];

或者嵌套创建:

NSArray *array=@[@{@"some_key":@{@"another_key":@"another_value"}}];
