如何在目标 C 的 NSDictionary 中存储 { "Abc" ： "Xyz" }

Question

如何将下面给出的内容存储到NSDictionary

{

"测试":"例子"

}

Answer 1

您可以使用

为key添加值

NSDictionary *dictionary=[NSDictionary dictionaryWithObjectsAndKeys:@"Test",@"Example", nil];

Answer 2

您可以使用'initWithObjects:(objects) forKeys:'为key添加值

NSDictionary* dictionary = [[NSDictionary alloc] initWithObjects:@[@"Example",@"Example2"] forKeys:@[@"Test",@"Test2"]];
NSLog(@"%@",dictionary);
//{
//    Test = Example;
//    Test2 = Example2;
//}

或者你可以使用NSMutableDictionary:

 NSMutableDictionary *mutableDictionary = [[NSMutableDictionary alloc] init];
[mutableDictionary setObject:@"Example" forKey:@"Test"];
[mutableDictionary setObject:@"Example2" forKey:@"Test2"];
NSLog(@"%@",mutableDictionary);
//{
//    Test = Example;
//    Test2 = Example2;
//}

这些的输出相同。你还应该看看
