ios6

问题 I used AppleKeyboards to get users' keyboard setting before iOS6: NSArray * keyboards = [[NSUserDefaults standardUserDefaults] objectForKey:@"AppleKeyboards"]; for (int i = 0; i < [keyboards count]; i++) { NSLog(@"%@", [keyboards objectAtIndex:i]); } But after iOS6, I can't use AppleKeyboards as key for the user setting. Is there any solution for this? Thanks! 回答1: You can use UITextInputMode Class to get current text input mode by "+ (UITextInputMode *)currentInputMode". see also: https:/

问题 My app is a scorekeeper with two tabs. Tab one is where scorekeeping actually takes place, and tab two contains history of past games. Only tab one supports rotation, and when rotating it hides its navigation and tab bars (there's not enough vertical space). I do not want to support rotation at all on the history tab, because the tabbar is hidden in the counter. It is quite jarring to switch tabs and then have the tab bar disappear. There are several types of games that may be displayed in

问题 Can I register for SMS Notification through my application?

You will need to track what you are setting up with your MFMessageComposeViewController as you are helping them prepare to send an SMS message. But you can't tell if they added other recipients or deleted the ones you set up
