When you send a text message with iphone4, delete all the text messages you just wrote, and ask for some tips. What's the best way?

Just shake your little 4 a few times and a window will pop up. Select "Cancel Input" to delete all contents. You don't have to press the delete key for a long time. If it is just pasted, shaking can "undo pasting" (supplementary: it can also be used for other IM input. )

Other skills: Write short messages, select all short messages, and choose replacement, and you will find that your simplified Chinese has magically become traditional Chinese. Simple and complex transformation is as simple as that. Friendly reminder: many children's shoes can't be converted, because the premise of conversion is that the font you want to convert must have the corresponding traditional, so there will be a replacement button. )

3. Punctuation Quick Input Method If you want to input punctuation quickly, you can press and hold the "123" key, slide to the punctuation you want to input, and then release it. You can see that the symbol has been entered, and the keyboard automatically returns to the alphabetic keyboard. In addition, pressing a space after entering punctuation marks will automatically jump back to the alphabet keyboard, which is very user-friendly for English input. Double-clicking a space will automatically enter ".";

(supplement: when typing, press the space with two fingers together, or you can just stop. )
