无聊的测试。release后还需要removeallobjects？-优快云博客

本文通过一个Objective-C的ViewController实例，详细介绍了如何正确地管理内存，包括对象的创建、使用和释放过程。特别关注了retainCount属性的变化以及合理释放资源的重要性。

#import <UIKit/UIKit.h>

@interface ViewController : UIViewController{
    NSMutableArray *_mArray;
    NSMutableArray *temp;
}

@property(nonatomic ,retain)NSMutableArray *mArray;
@end

#import "ViewController.h"

@interface ViewController ()

@end

@implementation ViewController

@synthesize mArray = _mArray;


-(void)reResultRetainCount{
    static int i = 1;
    NSLog(@"get %d _mArray retain count %d",i++,[_mArray retainCount]);
}


- (void)viewDidLoad
{
    [super viewDidLoad];
	// Do any additional setup after loading the view, typically from a nib.
//    [self reResultRetainCount];
//    
//    _mArray = [[NSMutableArray alloc] init];
//    
//    [self reResultRetainCount];
//    
//    [_mArray release];
    
    [self reResultRetainCount];
    
    _mArray = [[NSMutableArray alloc] init];
    
    [self reResultRetainCount];
    
    [self.mArray addObject:@"123"];
    [self.mArray addObject:@"456"];
    [self.mArray addObject:@"789"];
    
   /*
    NSLog(@"%@",self.mArray);
    [_mArray removeAllObjects];
    NSLog(@"%@",self.mArray);
 */

    [self reResultRetainCount];
    NSLog(@"%@",_mArray);
    
    temp = [_mArray copy];

    [_mArray release];
    
    
    [self reResultRetainCount];
    
    
    if (temp) {
        
        //NSLog(@"temp");
        NSLog(@"%@",temp);
        
    }
    
  
}



- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}
//
//-(void)setMArray:(NSMutableArray *)mArray{
//    
//    if (_mArray != mArray) {
//        
//        //_mArray = mArray;
//
//        [_mArray release];
//        _mArray = [mArray retain];
//        
//    }
//    
//    NSLog(@" set mArray retain count %d",[mArray retainCount] );
//
//}


@end

总结，不需要。在跑道dealloc 里面去释放的时候，再去removeallobjects。

最多，加上 currentObjets ＝ nil这句话。

安全释放。合理分配。

共享内存，不要随便放。

和同事辩论，结果，V字手势。
