Summary of Itextview recycling or turning off keyboard usage in Uios development _android

iOS development, found Uitextview not like Uitextfield in Textfieldshouldreturn: This method, then to implement Uitextview close the keyboard, you must use other methods, the following is a few ways to use.

1. If your program has a navigation bar, you can add more than one done button on the navigation bar, used to exit the keyboard, of course, first real uitextviewdelegate.

-(void) textviewdidbeginediting: (Uitextview *) TextView { 
Uibarbuttonitem *done = [[Uibarbuttonitem alloc] Initwithbarbuttonsystemitem:uibarbuttonsystemitemdone target:self Action: @selector (Leaveeditmode)] autorelease]; 
Self.navigationItem.rightBarButtonItem = done; 
} 
-(void) textviewdidendediting: (Uitextview *) TextView { 
Self.navigationItem.rightBarButtonItem = nil; 
} 
-(void) Leaveeditmode { 
[Self.textview resignfirstresponder]; 
}

2. If you do not use enter in the TextView, you can use the return key as a response to exit the keyboard.

-(BOOL) TextView: (Uitextview *) TextView Shouldchangetextinrange: (nsrange) Range Replacementtext: (NSString *) text 
{ 
if ([text isequaltostring:@ "\ n"]) { 
[TextView resignfirstresponder]; 
return NO; 
} 
return YES; 

This way, whether you're using the ENTER key on your computer's keyboard or using the return button on your pop-up keyboard, you can get out of the keyboard.

3. The third method feels better than either of the above, which is to put a view on the keyboard above to place the done button that exits the keyboard.

 Uitoolbar * TopView = [[Uitoolbar alloc]initwithframe:cgrectmake (0, 0, 320, 30)]; 
[TopView Setbarstyle:uibarstyleblack]; Uibarbuttonitem * Hellobutton = [[Uibarbuttonitem alloc]initwithtitle:@ "Hello" style:uibarbuttonitemstylebordered 
Target:self Action:nil]; Uibarbuttonitem * Btnspace = [[Uibarbuttonitem alloc]initwithbarbuttonsystemitem:uibarbuttonsystemitemflexiblespace 
Target:self Action:nil]; Uibarbuttonitem * Donebutton = [[Uibarbuttonitem alloc]initwithtitle:@ ' done ' style:uibarbuttonitemstyledone target: 
Self action: @selector (Dismisskeyboard)]; 
Nsarray * Buttonsarray = [Nsarray arraywithobjects:hellobutton,btnspace,donebutton,nil]; 
[Donebutton release]; 
[Btnspace release]; 
[Hellobutton release]; 
[TopView Setitems:buttonsarray]; 
[Tvtextview Setinputaccessoryview:topview]; 
-(Ibaction) Dismisskeyboard {[Tvtextview resignfirstresponder]; }
