ios - UITextfield的位置设置不正确

我正在制作一个我想设置UITextfield位置的应用程序。但是我陷入其中，它仅设置vertical position而不是horizontal position。下面是我的代码和屏幕截图

Msgtextfield.placeholder=@"demo";
CGRect frame = CGRectMake(100,100,10,100);
UILabel * leftView = [[UILabel alloc] initWithFrame:frame];
leftView.backgroundColor = [UIColor clearColor];
self.Msgtextfield.leftView = leftView;
self.Msgtextfield.leftViewMode = UITextFieldViewModeAlways;
self.Msgtextfield.contentVerticalAlignment = UIControlContentVerticalAlignmentCenter;
   self.Msgtextfield.contentHorizontalAlignment=UIControlContentHorizontalAlignmentCenter;

最佳答案

使用CATransform3DMakeTranslation不要忘记导入Quartzcore framework

 self.Msgtextfield.layer.sublayerTransform=CATransform3DMakeTranslation(5, 0, 0);
