我需要能够检查我是否已经在
objective-c中发布了一个变量.我试过检查它是否变为null：
//Checks if buildview is null and returns respective output
if(BuildView == NULL)
NSLog(@"Build View Value (pointer): Null");
else
NSLog(@"Build View Value (pointer): Not Null");
//allocates memory and initalizes value
BuildView = [[UIView alloc] initWithFrame:CGRectMake(0,10,10)];
//Checks if buildview is null and returns respective output again
if(BuildView == NULL)
NSLog(@"Build View Value (pointer): Null");
else
NSLog(@"Build View Value (pointer): Not Null");
//Releases the view
[BuildView release];
//Checks if buildview is null and returns respective output again
if(BuildView == NULL)
NSLog(@"Build View Value (pointer): Null");
else
NSLog(@"Build View Value (pointer): Not Null");
结果是：
Build View Value (pointer): Null Build View Value (pointer): Not Null Build View Value (pointer): Not Null
有没有更简单的方法来检查它是否被解除分配？
