objectiveC autorelease issue, what is wrong with code?
objective-c
Solution
When you are in the run loop of an application, there is a default autorelease pool created for you. However, when you are running with your own `main`, you need to create an autorelease pool manually at the top of your `main`, and drain it periodically.
NSAutoreleasePool *myPool = [[NSAutoreleasePool alloc] init];
// Your code that uses autorelease...
[myPool drain];
If you are compiling with the new LLVM compiler, use the new `@autoreleasepool` feature instead.
Problem
New to objective-C, ``` #import <objc/objc.h> #import <Foundation/Foundation.h> @interface Test:NSObject { int x,y, abc; NSString *v1, *v2; } @property int x , y, abc; -(void) print; @end @implementation Test @synthesize x,y, abc; -(void) print { NSLog (@"v1 and v2 values %i, %i ", v1, v2); } @end int main ( int argc, char **argv) { Test *t = [[Test alloc] init]; /* Synthesized Set Method */ [t setX:100]; [t setY:200]; /* Synthesized Get Method */ NSLog (@"Retrieving Values %i, %i ",[t x], [t y]); /* another Way to retrieve the throuhg KVC Model */ NSLog (@" KVC Retrieveal %i ", [t valueForKey:@"x"]); ``` } I did not get compile time error, but run time error i got : ``` 2012-04-11 16:25:08.470 testpgm[22237] Retrieving Values 100, 200 2012-04-11 16:25:08.513 testpgm[22237] autorelease called without pool for object (0x8e78ca0) of class NSMethodSignature in thread <NSThread: 0x8e23a08> 2012-04-11 16:25:08.514 testpgm[22237] autorelease called without pool for object (0x8e94610) of class NSIntNumber in thread <NSThread: 0x8e23a08> 2012-04-11 16:25:08.514 testpgm[22237] KVC Retrieveal 149505552 ``` Looks like it is something to do with memory issue. some one point out the issue ? NOTE: With all your inputs, i could resolve the autorelease issue, but still ``` NSLog (@" KVC Retrieveal %i ", [t valueForKey:@"x"]); ``` does not print the proper value but the garbage. Am i doing something wrong?
