       ........ 

- (void)dealloc {

    [mASIHTTPRequest release];

} 


@end

我簡單地推這個觀點再逼人退會的dealloc /釋放視圖控制器.. - 問題是，當我按下背部，同時它取崩潰 - 我怎樣才能克服這個任何建議將做tnxASIHTTPRequest作爲實例變量和釋放，釋放

mASIHTTPRequest = [ASIHTTPRequest requestWithURL:url];

你不保留這個請求。您需要保留它以具有有效的參考引用，然後才能取消並釋放它。要麼添加一個保留，要麼使用self.mASIHTTPRequest。

有點像這樣嗎？ 'self.mASIHTTPRequest = [ASIHTTPRequest requestWithURL：url]; [self.mASIHTTPRequest setDelegate：self]; [self.mASIHTTPRequest startAsynchronous];' 怎麼樣dealloc我也應該添加self.mASIHTTPRequest'[self.mASIHTTPRequest clearDelegatesAndCancel]; [self.mASIHTTPRequest發佈];' tnx爲快速回復可悲我不能測試代碼，直到星期一..虐待更新一次我測試。 – user966337

'self.mASIHTTPRequest = [ASIHTTPRequest requestWithURL：url];'會做;無需改變任何其他 – JosephH

謝謝它的作品..！我認爲它會在沒有'self.'的情況下工作，因爲我認爲它們在沒有它的情況下工作是一樣的。 – user966337
