How to Find Out the Content of a Dictionary when Debugging in Objective-c

- (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName attributes:(NSDictionary *)attributeDict

A familiar function. Now there is this attributeDict object.

I wan开发者_如何学运维t to know what are all the keypairs in the object.

I go to expression window and see that it contain NSObject that contains a reference to ISA.

So what should I do? NSLog?

You can select "Print Description" in the context (right click) menu. Or in the debug terminal window you can type po variablename. You can also, as you suggest, use NSLog.

You can print contents of your dictionary to console, for example using NSLog in your code:

NSLog("%@", attributeDict);

Or while debugging place breakpoint in that method and type in debugger console:

po attributeDict

You can use NSLog(@"%@",attributeDict); to print out the dictionary content.

If, for example, you have set a breakpoint and you are in GDB console you can use po attributeDict that stand for print object and do the same thing as NSLog
