What is the closest utility to Snoop for iPhone/iPad development?
Is there anything remotely close to the WPF Snoop utility for iPhone/iOS development?
I have found Mike Ash's ObjC wrapper, however this seems more helpful for reflection than for analyzing the instance state of UIKit hierarchies.
An example of where this is useful: I integrated a split-view inside of a tabbar view and it's not quite working. Yes there are some bits of code out there for this to just "make it work". However I want to get dirty and fix my own problems to better master the platform.
The most obvious i开发者_JS百科mplementations seem to be to pass in a root viewcontroller instance to a utility class method.
The utility could then output the UIKit hierarchy in the debug window, or to get fancy, popup a modal view that lets you graphically browse the state like Snoop.
If you want to get your hands dirty, just leverage objective-C's dynamic behavior, and implement it yourself. You could create a category on UIView with a recursive method that prints out info about its children. Then in GDB just call it on the window (since window is a subclass of UIView. Something like:
@interface UIView ( DebugExras )
- (void)debugPrintViewTree;
@end
And in GDB:
gdb: po [[[UIApplication sharedApplication] keyWindow] debugPrintViewTree]
