ios - UITextfield 的位置设置不正确

Question

我正在制作一个应用程序，我想设置 UITextfield 的位置。但我被困在里面，它只设置垂直位置而不是水平位置。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;

Answer 1

使用CATransform3DMakeTranslation不要忘记导入Quartzcore框架

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