我的应用程序在GC打开的情况下运行。
Instrument Leak总是告诉我这行代码有100%的内存泄漏:
[NSApp runModalForWindow:[theWindowController window]];
我不知道为什么。
以下是整个应用代码:
/* delegate */
#import "m_ModalWindowAppDelegate.h"
#import "modalWindowController.h"
@implementation m_ModalWindowAppDelegate
@synthesize window;
- (void)applicationDidFinishLaunching:(NSNotification *)aNotification {
// Insert code here to initialize your application
}
- (IBAction) openModalWindowButtonClicked: (id) sender
{
modalWindowController *theWindowController = [[modalWindowController alloc] init];
[NSApp runModalForWindow:[theWindowController window]];
[NSApp endSheet: [theWindowController window]];
[[theWindowController window] orderOut:self];
}
@end
/* modalWindowController */
#import "modalWindowController.h"
@implementation modalWindowController
- (id) init
{
self = [self initWithWindowNibName:@"modalWindow"];
return self;
}
- (IBAction) closeButtonClicked:(id)sender
{
[NSApp stopModal];
}
@end
答案 0 :(得分:0)
泄漏实际上比那一行高一行:
modalWindowController *theWindowController = [[modalWindowController alloc] init];
您正在分配modalWindowController并将其分配给本地指针。当方法结束时,指针超出范围,但您永远不会释放您分配的对象。此时,您无法再引用该对象(不再有指针),因此将来无法释放它。这是泄密。
