如何在Xcode调试器中查看NSDictionary变量的内容？ [英] How to view contents of NSDictionary variable in Xcode debugger?

问题描述

有没有办法通过Xcode调试器查看NSDictionary变量的键/值对？以下是在变量窗口中完全展开后的信息范围：

Is there a way to view the key/value pairs of a NSDictionary variable through the Xcode debugger? Here's the extent of information when it is fully expanded in the variable window:

Variable  Value      Summary
jsonDict  0x45c540   4 key/value pairs
 NSObject {...}
  isa     0xa06e0720

期望它显示字典的每个元素（类似于数组变量）。

I was expecting it to show me each element of the dictionary (similar to an array variable).

推荐答案

在gdb窗口中，您可以使用 po 。

In the gdb window you can use po to inspect the object.

给定：

NSMutableDictionary* dict = [[NSMutableDictionary alloc] init];
[dict setObject:@"foo" forKey:@"bar"];
[dict setObject:@"fiz" forKey:@"buz"];

在添加对象后设置断点可以检查字典中的内容

setting a breakpoint after the objects are added you can inspect what is in the dictionary

(gdb) po dict
{
  bar = foo;
  buz = fiz;
}

当然这些是 NSString 对象打印得很好。 YMMV与其他复杂对象。

Of course these are NSString objects that print nicely. YMMV with other complex objects.
