NSDictionary *dic1=[NSDictionary dictionaryWithObject:@"1" forKey:@"a"];
NSLog(@"%@",dic1);
/*结果:
{

} */
//常用的方式
NSDictionary *dic2=[NSDictionary dictionaryWithObjectsAndKeys:
@"1",@"a", @"2",@"b", @"3",@"c", nil];
NSLog(@"%@",dic2);
/*结果:
{
a = 1;
b = 2;
c = 3; }
*/
NSDictionary *dic3=[NSDictionary dictionaryWithObjects:[NSArray arrayWithObjects:@"1",@"2", nil] forKeys:[NSArray arrayWithObjects:@"a",@"b", nil]];
NSLog(@"%@",dic3);
/*结果:
{
a = 1;
b = 2;
}
*/
//更简单的方式
NSDictionary *dic4=@{@"1":@"a",@"2":@"b",@"3":@"c"};
NSLog(@"%@",dic4);
/*结果:
{
1 = a;
2 = b;
3 = c; }
*/
