在 iPhone 中使用自定义 init 方法 - 识别泄漏
对于我的一个自定义类，我定义了一种名为“initialize”的方法，用于在 init 的同时设置一些实例变量。代码如下。分析器工具报告 viewDidLoad 中存在 [[Employee alloc].. 由于我在 dealloc 中释放了变量，我认为这应该没问题......可能是什么问题？提前致谢。
@interface testViewController : UIViewController <UITextFieldDelegate>{
Employee *employee;
}
- (void)viewDidLoad {
if(employee ==nil)
employee = [[Employee alloc] initialize:@"John"];
if (![employee.entityName isEqualToString:@"Test"]) { //The leak is reported here for object allocated above
///...
}
}
- (void)viewDidUnload {
[super viewDidUnload];
employee = nil;
}
- (void)dealloc {
[super dealloc];
[employee release];
}
//In the Employee class
-(id) initialize:(NSString*) name{
self = [super init];
self.entityName = name;
return self;
}
For one of my custom classes, I have defined a method called initialize to set some instance variables at the same time as the init. The code is below. The analyzer tool is reporting a leak in viewDidLoad on the line with [[Employee alloc]..
Since I am releasing the variable in the dealloc, I thought that this should be fine..what could be the issue? thanks in advance.
@interface testViewController : UIViewController <UITextFieldDelegate>{
Employee *employee;
}
- (void)viewDidLoad {
if(employee ==nil)
employee = [[Employee alloc] initialize:@"John"];
if (![employee.entityName isEqualToString:@"Test"]) { //The leak is reported here for object allocated above
///...
}
}
- (void)viewDidUnload {
[super viewDidUnload];
employee = nil;
}
- (void)dealloc {
[super dealloc];
[employee release];
}
//In the Employee class
-(id) initialize:(NSString*) name{
self = [super init];
self.entityName = name;
return self;
}

在您的
viewDidUnLoad中，您需要在将其设置为nil之前release员工。否则，在您的dealloc中，您只是释放nil。IE
In your
viewDidUnLoadyou need toreleaseemployee before it gets set tonil. Else in yourdealloc, you are just releasingnil.ie
