请问一个问题 关于也页面销毁的问题

[aalj]

在进入一个页面的时候发出的请求，但是由于网络很慢请求没返回，这是关闭了这页面， 在该项目里面presenter解绑以后iView置空了，抛出了空指针异常， 对于这种情况，如果不采用那种在使用iView的时候进行空判断 怎么解决比较好。

有两种办法，一在ondestory前取消网络请求；二在接口基类回调做个判断，view为空直接return发自我的iPhone------------------ 原始邮件 ------------------发件人: aalj <[email protected]>发送时间: 2018年10月12日 16:13收件人: xybCoder/gank <[email protected]>抄送: Subscribed <[email protected]>主题: 回复：[xybCoder/gank] 请问一个问题 关于也页面销毁的问题 (#6)在进入一个页面的时候发出的请求，但是由于网络很慢请求没返回，这是关闭了这页面， 在该项目里面presenter解绑以后iView置空了，抛出了空指针异常， 对于这种情况，如果不采用那种在使用iView的时候进行空判断 怎么解决比较好。 —You are receiving this because you are subscribed to this thread.Reply to this email directly, view it on GitHub, or mute the thread. {"api_version":"1.0","publisher":{"api_key":"05dde50f1d1a384dd78767c55493e4bb","name":"GitHub"},"entity":{"external_key":"github/xybCoder/gank","title":"xybCoder/gank","subtitle":"GitHub repository","main_image_url":"https://assets-cdn.github.com/images/email/message_cards/header.png","avatar_image_url":"https://assets-cdn.github.com/images/email/message_cards/avatar.png","action":{"name":"Open in GitHub","url":"https://github.com/xybCoder/gank"}},"updates":{"snippets":[{"icon":"DESCRIPTION","message":"请问一个问题 关于也页面销毁的问题 (#6)"}],"action":{"name":"View Issue","url":"#6"}}} [ { "@context": "http://schema.org", "@type": "EmailMessage", "potentialAction": { "@type": "ViewAction", "target": "#6", "url": "#6", "name": "View Issue" }, "description": "View this Issue on GitHub", "publisher": { "@type": "Organization", "name": "GitHub", "url": "https://github.com" } }, { "@type": "MessageCard", "@context": "http://schema.org/extensions", "hideOriginalBody": "false", "originator": "AF6C5A86-E920-430C-9C59-A73278B5EFEB", "title": "请问一个问题 关于也页面销毁的问题 (#6)", "sections": [ { "text": "", "activityTitle": "**aalj**", "activityImage": "https://assets-cdn.github.com/images/email/message_cards/avatar.png", "activitySubtitle": "@aalj", "facts": [ { "name": "Repository: ", "value": "xybCoder/gank" }, { "name": "Issue #: ", "value": 6 } ] } ], "potentialAction": [ { "name": "Add a comment", "@type": "ActionCard", "inputs": [ { "isMultiLine": true, "@type": "TextInput", "id": "IssueComment", "isRequired": false } ], "actions": [ { "name": "Comment", "@type": "HttpPOST", "target": "https://api.github.com", "body": "{\n\"commandName\": \"IssueComment\",\n\"repositoryFullName\": \"xybCoder/gank\",\n\"issueId\": 6,\n\"IssueComment\": \"{{IssueComment.value}}\"\n}" } ] }, { "name": "Close issue", "@type": "HttpPOST", "target": "https://api.github.com", "body": "{\n\"commandName\": \"IssueClose\",\n\"repositoryFullName\": \"xybCoder/gank\",\n\"issueId\": 6\n}" }, { "targets": [ { "os": "default", "uri": "#6" } ], "@type": "OpenUri", "name": "View on GitHub" }, { "name": "Unsubscribe", "@type": "HttpPOST", "target": "https://api.github.com", "body": "{\n\"commandName\": \"MuteNotification\",\n\"threadId\": 392428913\n}" } ], "themeColor": "26292E" } ]
