IOS basic memory management series 4-autorelease method and @ autoreleasepool

• When the autorelease method is executed, the object is added to the Auto Release pool.
• When the automatic release pool is destroyed, all objects in the pool are automatically released for the release operation.
• After the object executes the autorelease method, its reference counter will not change and the object itself will be returned.

• Autorelease actually only delays the call to release. For each autorelease system, this object is only put into the current autorelease pool. When the pool is released, all objects in the pool will be called Release

• Because only objects in the automatically released pool are destroyed, you do not need to worry about the object destruction time or when to call release.

 

• Do not use objects that occupy a large amount of memory during operations. It is too late to release objects.
• Objects that occupy less memory can use
