self.mTFUserName.returnKeyType = UIReturnKeyNext;//Next按钮
self.mTFUserName.delegate = self;
self.mTFPassWord.returnKeyType = UIReturnKeyDone;//Done按钮
self.mTFPassWord.delegate = self;
3:响应事件函数
- (BOOL)textFieldShouldReturn:(UITextField *)textField
{
if (textField == self.mTFUserName)
{
[self.mTFPassWord becomeFirstResponder];
}else if (textField == self.mTFPassWord){
[self mBTLogin:self.BTLogin];
}
return YES;
