问题 Lets say I have the below scenario: - (void)someFunction:(id)param { NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init]; NSObject *objectA = [[NSObject alloc] init]; [objectA doStuff]; // Don't need to release objectA because of the pool if (!someValue) { [pool release]; // Doubt here return; } NSObject *objectB = [[NSObject alloc] init]; [objectB doStuff]; // Don't need to release objectB because of the pool [pool release]; } Is it right to return from inside the pool block in this

Image loading with GCD receiving memory warning

假装没事ソ 提交于 2019-12-10 23:27:57
问题 I'm developing a photo gallery application using AssetsLibrary to load my device photos. When presenting a random image in another VC I've noticed the following : it takes about 1 or 2 seconds for my full res image to load on the imageView (way much longer than the native photosApp) and I also get from the log "Received memory warning" after loading a few images. If I set my representation to fullScreenImage the warnings stop but I don't want this. What must I change for a smooth performance

NSAutorelease memory leak

问题 I am getting this error message in the console: *** _NSAutoreleaseNoPool(): Object 0x10d2e0 of class NSPathStore2 autoreleased with no pool in place - just leaking I can't figure out what is the error? Thanks. 回答1: This is a classic memory management issue, you are autoreleasing some objects without having an autorelease pool in place. Autoreleasing is not a magic. There is an object of type NSAutoreleasePool that keeps track of all objects you autorelease and ‘from time to time’ releases

Memory leak in cellForRowAtIndexPath:

这一生的挚爱 提交于 2019-12-08 11:56:40
问题 I would like, given the indexPath, to get a reference to the related cell to remove the checkmark. I thought I could use the cellForRowAtIndexPath for this, but I get the message: __NSAutoreleaseNoPool(): Object 0x685a600 of class UITableView autoreleased with no pool in place - just leaking even for a simple line like this: [self.tableView cellForRowAtIndexPath:indexPath]; So, this is not only returning a pointer to a cell, right? Maybe I'm misunderstanding what this method is for. Is it

问题 Whenever we are calling autorelease method, its object is going to NSAutoreleasePool . When the pool is drained, it is sending release to all the objects in the pool. My question is; In the main function there is one NSAutoreleasePool . I want to know that; when we call the autorelease method, where it is sending the object ? I mean; it is sending the object to NSAutoreleasePool which is in main function (or) somewhere ? Thanks in advance. 回答1: There is actually a stack of autorelease pools.

No autorelease pool with JOGL

问题 I tried to add JOGL to my project, and after a long time searching the web I found the solution. I added the jars to my buildpath and Eclipse recognizes them. I wanted to test it, so took the code from here: https://sites.google.com/site/justinscsstuff/jogl-tutorial-2 and compiled.
