我創建的UITabBarController編程,這樣我的內存泄露了嗎?
mTabBarController = [[UITabBarController alloc] init];
...
NSLog(@"The ref count is : %d", [tabBarItems retainCount]);
mTabBarController.viewControllers = tabBarItems;
NSLog(@"The ref count is : %d", [tabBarItems retainCount]);
[tabBarItems release];
NSLog(@"The ref count is : %d", [tabBarItems retainCount]);
此外,在dealloc中釋放mTabBarController,這樣,
- (void)dealloc {
[mTabBarController release];
...
}
現在的問題:輸出的第一代碼片段是
2011-11-01 17:48:26.554 PostCardPrinter[12176:207] The ref count is : 1
2011-11-01 17:48:26.561 PostCardPrinter[12176:207] The ref count is : 1
2011-11-01 17:48:26.561 PostCardPrinter[12176:207] The ref count is : 1
我得到內存泄漏?爲什麼總是打印1?
如果它保留tabBarItems則第二輸出應爲2。如果
mTabBarController.viewControllers = tabBarItems;
拷貝數組項並保留每個各數組項然後,該第三輸出應該B 2嗎?
我有什麼問題嗎?
讓retainCount咆哮開始吧! - 編輯:發現它http://stackoverflow.com/questions/4636146/when-to-use-retaincount – Joe

好吧,因爲我是新的iOS開發,我真的需要你的評論;)順便說一句,你最好寫一個答案比評論... – deimus
