Something about iOS 7

I found when I use pinyin for typing, sometimes I can't get the Chinese characters. At first I think maybe there are something wrong with my cellphone. I don't know why it was is, then I searched Baidu. I found many people discussed the problem, and I realized it was because of the iOS 7. Some people suggested to add a Japanese keyboard, then typed some Japanese letters, and it would be should worked out. I didn't believe it, but after I try tried, I found this problem really be was solved. I don't know why should I had to add the Japanese keyboard, anyways it was be worked out, but I don't like to add more keyboards, because there are seven keyboards in my cellphone. What a troublesome problem!
我发现当我用拼音打字的时候，有时候我不能得到汉字。起初，我认为也许是我手机的问题。我不知道这是为什么，接着我搜索了百度。我发现有很多人讨论这个问题，这时我才意识到原来是由于iOS7的问题。有人建议添加一个日语键盘，然后打几个日文字母，问题就会解决了。我不相信，但试过之后，我发现问题确实解决了。我不知道为什么我必须添加日语键盘，尽管问题解决了，但是我不喜欢再添加键盘。因为我的手机上已经有7个键盘了。这真是个麻烦的问题！
