内存泄漏问题

Question

有如下代码 
headerViewArray = [[NSMutableArray alloc] init]; 
    UIView* customView; 
     
    customView = [[UIView alloc] initWithFrame:CGRectMake(0,0,300,40)]; 
    [headerViewArray addObject:customView]; 
    customView = [[UIView alloc] initWithFrame:CGRectMake(0,0,300,40)]; 
    [headerViewArray addObject:customView]; 
    customView = [[UIView alloc] initWithFrame:CGRectMake(0,0,300,40)]; 
    [headerViewArray addObject:customView]; 
    customView = [[UIView alloc] initWithFrame:CGRectMake(0,0,300,40)]; 
    [headerViewArray addObject:customView]; 
 
在dealloc函数中有： 
[headerViewArray release]; 
 
问：上述customView = [[UIView alloc] initWithFrame:CGRectMake(0,0,300,40)]; 是否产生了内存泄漏 
是否需要调用 
[customView release]; 
也就是变成如下： 
    headerViewArray = [[NSMutableArray alloc] init]; 
    UIView* customView; 
     
    customView = [[UIView alloc] initWithFrame:CGRectMake(0,0,300,40)]; 
    [headerViewArray addObject:customView]; 
    [customView release]; 
    customView = [[UIView alloc] initWithFrame:CGRectMake(0,0,300,40)]; 
    [headerViewArray addObject:customView]; 
    [customView release]; 
    customView = [[UIView alloc] initWithFrame:CGRectMake(0,0,300,40)]; 
    [headerViewArray addObject:customView]; 
    [customView release]; 
    customView = [[UIView alloc] initWithFrame:CGRectMake(0,0,300,40)]; 
    [headerViewArray addObject:customView]; 
    [customView release]; 
才不会产生内存泄漏

Answer 1

需要调用  
[customView release]; 

Answer 2

你可以：
customView = [[[UIView alloc] initWithFrame:CGRectMake(0,0,300,40)] autorelease];也可以：
customView = [[UIView alloc] initWithFrame:CGRectMake(0,0,300,40)]; 
[headerViewArray addObject:customView]; 
[customView release];
