由 落花浮王杯 提交于 2020-01-01 02:43:08
问题 I have just migrated to Xcode 4 and i had zombie activated in Xcode 3 for my app. I used the following method: Go to Project -> Edit Active Executable Click Arguments Click + in the "Variables to be set in the environment" section Enter NSZombieEnabled in the Name column and YES in the Value column. Make sure the checkmark for the NSZombieEnabled entry is checked. Now i want to make sure it is off for my application but do not understand how to check/do that in XCODE4, anyone that can share

问题 I have a huge set of data, those are displayed in a customized NSOutlineView . Sometime my app gets crashed and gives me this error, while running in Xcode: libobjc.A.dylib objc_assign_strongCast_non_gc(objc_object*, objc_object**)` Any idea about this one? Your replies would certainly help me to figure it out. EDIT: What I have tried so far: I have put all exception breakpoints and enabled NSZombieEnabled . But is never caught. I have use Binding to populate the NSOutlineView . The array

Why is object not dealloc'ed when using ARC + NSZombieEnabled

由 末鹿安然 提交于 2019-12-11 02:36:42
问题 I converted my app to ARC and noticed that an object alloc'ed in one of my view controllers was not being dealloc'ed when that view controller was dealloc'ed. It took a while to figure out why. I have Enable Zombie Objects on for my project while debugging and this turned out to be the cause. Consider the following app logic: 1) Users invokes action in RootViewController that causes a SecondaryViewController to be created and presented via presentModalViewController:animated . 2)

Should NSZombieEnabled be turned off for released app or not?

问题 With NSZombieEnabled turned on it will provide some guard against the EXC_BAD_ACCESS issues happening at runtime. I am doing dual-diligence to make sure no/little memory leaks, but I might over releasing so having NSZombieEnabled turned on would help prevent that, am I right? Or with NSZombieEnabled turned on, would all memory releasing operations be translated into no-op? It'll be a big problem is that's the case. 回答1: No, you should not ship with NSZombiesEnable . Zombies work by casting

Xcode Instruments - Zombies - what am I looking for?

问题 When I run Project/Profile in Xcode and choose " Zombies ", the app runs in the simulator with " NSZombie detection " enabled. But what should I be looking for to tell me that there is a problem? All I see is the Allocation instrument running and the statistics below. Where will it actually show me that a Zombie was detected? 回答1: You will get the leak above the object allocation bar.

NSZombieEnabled FIXES my app?

问题 When I push a certain view controller, then go pop it and then repeat a seemingly random number of times the app eventually crashes with the error EXC_BAD_ACCESS. This I can reliably replicate EVERY TIME. It happens mostly the second time I pop the view controller, but sometimes it can be the third or fourth. So I decided to set NSZombieEnabled to see what the problem was. But with this enabled the crash can't be replicated. All thats changed is I check the box next to "NSZombieEnabled" in my

All thats changed is I check the box next to "NSZombieEnabled" in my active executable's config and the app works perfectly. Any ideas what is causing this? Thanks I had
