UITextFiled鍵盤彈出前做ASI請求並且彈出自定view

.H裏面定義的@property(nonatomic,strong)UITextField *publicFiled;

    @property(nonatomic,strong)UIView *typePickerView;

.M文件裏

#pragma mark - UITextFieldDelegate

- (void)textFieldDidBeginEditing:(UITextField *)textField{

             self.publicFiled=textField;

            self.publicFiled.inputView=self.typePickerView;

}

-(BOOL)textFieldShouldBeginEditing:(UITextField *)textField{
    if (self.outPatientList.count==0&&!self.typePickerView) {
        self.publicFiled=textField;
        [self listDataSource:[NSNumber numberWithInt:TAG_FOURTY_NINE] ];//自定義了一個方法用不請求網絡數據的
        return NO;

    }
    return YES;
}

//異步請求委託
- (void)requestFinished:(ASIHTTPRequest *)request

                    self.typePickerView=(UIView *)([[NSBundle mainBundle]loadNibNamed:@"OutPatientType" owner:self options:nil][0]);//此處的@"OutPatientType"是我定義好的一個view.xib

                     UIPickerView *typePKV=(UIPickerView *)[self.typePickerView viewWithTag:1];
