objective c - Dismissing the UIPicker after user is done using it in a UITextField? -

i have uipicker shown when user selects specific uitextfield. problem having this: have added working picker called mypicker , text field called field.

i have looked @ several questions asking getting picker pop instead of picker, have not come across 1 right answer me.

i able mypicker show changing text field's inputview problem cannot figure out way add accessory toot bar perhaps "done" button.

for testing purposes added simple button action :

self.mypicker.hidden = yes;  [_field resignfirstresponder]; 

but giving me weird, non animated doesn't feel right.

here code this:

#import "viewcontroller.h"  @interface mixerhpviewcontroller () @property (weak, nonatomic) iboutlet uilabel *testlabel; @property (weak, nonatomic) iboutlet uitextfield *field; @property (weak, nonatomic) iboutlet uipickerview *mypicker; @property (weak, nonatomic) iboutlet uitextfield *field2; - (ibaction)takebutton:(id)sender;    @end  @implementation viewcontroller  @synthesize templist;    // returns number of 'columns' display. - (nsinteger)numberofcomponentsinpickerview:(uipickerview *)pickerview {     return 1; }  // returns # of rows in each component.. - (nsinteger)pickerview:(uipickerview *)pickerview numberofrowsincomponent:(nsinteger)component {     return [templist count]; }  - (nsstring *)pickerview:(uipickerview *)pickerview titleforrow:(nsinteger)row forcomponent:(nsinteger)component {     return [templist objectatindex:row]; }  - (void)pickerview:(uipickerview *)pickerview       didselectrow:(nsinteger)row        incomponent:(nsinteger)component {     cgfloat chosenvalue;      switch (row) {         case 0:             chosenvalue = 0.0000765;             break;         case 1:             chosenvalue = 0.0000123;             break;         case 2:             chosenvalue = 0.0000982;             break;         case 3:             chosenvalue = 0.0000933;             break;         case 4:             chosenvalue = 0.0000058;             break;         case 5:             chosenvalue = 0.0000121;             break;         case 6:             chosenvalue = 0.0000132;             break;         default:             chosenvalue = 0;             break;     }  nsnumberformatter *formatter = [[nsnumberformatter alloc]init];     formatter.numberstyle = nsnumberformatterdecimalstyle;     formatter.minimumfractiondigits=7;  self.testlabel.text = [formatter stringfromnumber:@(chosenvalue)];   }  - (id)initwithnibname:(nsstring *)nibnameornil bundle:(nsbundle *)nibbundleornil {     self = [super initwithnibname:nibnameornil bundle:nibbundleornil];     if (self) {         // custom initialization     }     return self; }  - (void)viewdidload {     [super viewdidload];     // additional setup after loading view.     templist = [[nsarray alloc] initwithobjects:@"option a",@"option b",@"option c",@"option d",@"option f",@"option g",@"option h", nil];  }  - (void)didreceivememorywarning {     [super didreceivememorywarning];     // dispose of resources can recreated. }      - (void)textfielddidbeginediting:(uitextfield *)textfield {      if( textfield == self.field ) {         self.field.inputview = _mypicker;      } }    - (ibaction)takebutton:(id)sender {     self.mypicker.hidden = yes;     [_field resignfirstresponder]; } @end 

you can dismiss animations:

 - (ibaction)takebutton:(id)sender {     [uiview beginanimations:nil context:nil];     [uiview setanimationduration:0.5];     [uiview setanimationdelay:1.0];     [uiview setanimationcurve:uiviewanimationcurveeaseout];      //you can customize     self.mypicker.frame = cgrectmake(-100, -100, 100, 200);       [uiview commitanimations];      [self.mypicker removefromsuperview];     [_field resignfirstresponder];    }
