instruments

I know it's possible to get a screenshot programmatically from code in the iOS application, and to manually get screenshots from Xcode and Instruments (Instruments also automatically takes screenshots during UIAutomation test failures). What I would like to find is a programatic way (with code running on the Mac, not the device) to grab screenshots from the device onto the Mac which it is plugged into. Is there an API (or command-line parameters) into Xcode or Instruments to get access to this screenshot feature? Or (ideally) to interface to the device and get a screenshot directly, the same

I am developing a iPhone app and everything works fine so far. I can build and start the app in the simulator. But when I now start the app with Instruments I got the error: Dyld Error Message: Symbol not found: _CFXMLNodeGetInfoPtr Referenced from: /System/Library/Frameworks/Security.framework/Versions/A/Security Expected in: /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator3.0.sdk/System/Library/Frameworks/CoreFoundation.framework/Versions/A/CoreFoundation I've googled but did not find a solution. Hope somebody can help me out. Thx I think you're linking against

So I'm using recursive blocks. I understand that for a block to be recursive it needs to be preceded by the __block keyword, and it must be copied so it can be put on the heap. However, when I do this, it is showing up as a leak in Instruments. Does anybody know why or how I can get around it? Please note in the code below I've got references to a lot of other blocks, but none of them are recursive. __block NSDecimalNumber *(^ProcessElementStack)(LinkedList *, NSString *) = [^NSDecimalNumber *(LinkedList *cformula, NSString *function){ LinkedList *list = [[LinkedList alloc] init]; NSDictionary

I am developing an app using ARC When profiling my app in instruments for memory leaks it shows leaks at the following function: #import <UIKit/UIKit.h> #import "AppDelegate.h" int main(int argc, char *argv[]) { @autoreleasepool { return UIApplicationMain(argc, argv, nil, NSStringFromClass([AppDelegate class])); } } Does this indicate a problem somewhere else in my code? This is the stack trace 0 libsystem_c.dylib malloc 1 libsystem_c.dylib strdup 2 libnotify_sim.dylib token_table_add 3 libnotify_sim.dylib notify_register_mach_port 4 libnotify_sim.dylib notify_register_dispatch 5

Until very recently, instruments worked fine. I don't know what I did to make it mad, but now it won't attach to any device that I try to Profile with; no device at all. I've tried an iPhone, iPad, and 2 iPod touches; no luck! I'm using XCode 4. Here is the sequence of events: With device attached, click Product->Profile. App compiles onto device. Instruments launches, but an error sound is heard The record button is grayed out. Choose Target doesn't allow me to attach or choose target (empty list). Background points: Profile is set to Debug build within the Scheme of the project. This is true

I have watched this video http://www.markj.net/iphone-memory-debug-nszombie/ The guy shows an option called Enable NSZombie Detection on Allocations inside instruments, but my Instruments doesn't shows this option. This guy's video was done using a one year old version of Instruments and I am using Xcode 3.2.5. Do you guys know where this option is now? How can I enable it for iPhone apps? thanks In XCode 4.0, this 'Enable Zombie' option is only present in iPhone simulator and not when you profile on actual device. The zombie option is available in Xcode 3.2.6 under the allocations tool if you
