小编use*_*597的帖子

我正在尝试将iOS应用程序保持活动状态超过10分钟,当它进入后台状态时.

我该如何实现呢.

我有一个字符串如下

NSString str1 = @"Hello your bal = 68094";

我想在字符串中遇到"="符号后删除所有字符.

任何人都可以给我解决方案吗？

我正在尝试整合新的GoogleMaps sdk 1.10.1,然后我从https://developers.google.com/maps/documentation/ios/start快速入门

但我收到以下错误,我遇到了重复的符号错误.

我正在使用STTwitterAPI创建执行twitter所有操作的应用程序.我正在收到时间表Feed.但是如何使用相同的API发布推文.我搜索了这个但是我发现只有SLComposeViewController发布推文,它将呈现控制器,然后我们可以发布带有位置和图像的推文.我想要做的是创建我自己的撰写视图.因此,如果任何人有这方面的解决方案,请写这个线程.

Thnx和问候,
