UITextfield的位置设置不正确

Question

我正在创建一个应用程序，我想设置UITextfield的位置。但我被困在其中，它只设置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;

Answer 1

使用CATransform3DMakeTranslation不要忘记导入Quartzcore framework

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

Answer 2

UITextField.layer.sublayerTransform=CATransform3DMakeTranslation();

此行有效..

Answer 3

制作Textfield的类别类。

<强>的UITextField + bgImageset.h

@interface UITextField (bgImageset)
-(CGRect)textRectForBounds:(CGRect)bounds;
-(CGRect)editingRectForBounds:(CGRect)bounds;

<强>的UITextField + bgImageset.m

@implementation UITextField (bgImageset)

#pragma clang diagnostic push
#pragma clang diagnostic ignored "-Wobjc-protocol-method-implementation"
-(CGRect)textRectForBounds:(CGRect)bounds {

    return CGRectMake(bounds.origin.x+10 , bounds.origin.y ,
                      bounds.size.width - 10 , bounds.size.height );
}
-(CGRect)editingRectForBounds:(CGRect)bounds {
    return [self textRectForBounds:bounds];
}

导入此类以更改光标位置并更改文本字段光标的X位置。
