| 27 | * Before: |
| 28 | * |
| 29 | * var = [aObject retain]; |
| 30 | * [aObject release]; |
| 31 | * [aObject autorelease]; |
| 32 | * [super dealloc]; |
| 33 | * CFFunction(obj); |
| 34 | * |
| 35 | * ARC and Non-ARC compatible: |
| 36 | * |
| 37 | * #import "TObjective-C.h" |
| 38 | * var = [aObject retain_stub]; |
| 39 | * [aObject release_stub]; |
| 40 | * [aObject autorelease_stub]; |
| 41 | * [super dealloc_stub]; |
| 42 | * CFFunction(bridge_stub obj); |
| 43 | * |
| 44 | * Don't use retain_stub for @property(retain). |
| 45 | * Use NSAutoreleasePool like this: |
| 46 | * #if __has_feature(objc_arc) |
| 47 | * @autoreleasepool { |
| 48 | * // code |
| 49 | * } |
| 50 | * #else |
| 51 | * NSAutoReleasePool *pool = [[NSAutoReleasePool alloc] init... |
| 52 | * // code |
| 53 | * [pool release]; |
| 54 | * #endif |
