解决iOS UITextField 编辑时文本偏移问题

 1.在cell中添加uitextfield,在编辑的时候总是出现文本偏移问题,编辑结束时回复正常,解决方式如下:

(1)代码创建uitextfield,并添加上去,设置textfield的一些属性:

- (uitextfield *)textfield{
 if (_textfield == nil) {
  _textfield = [uitextfield new];
  _textfield.borderstyle = uitextborderstylenone;
  _textfield.contentverticalalignment = uicontrolcontentverticalalignmentcenter;
  _textfield.textalignment = nstextalignmentleft;
  _textfield.clearbuttonmode = uitextfieldviewmodewhileediting;
  _textfield.tintcolor = [uicolor redcolor];
  _textfield.font = gxfont(16);
  _textfield.returnkeytype = uireturnkeydone;
  _textfield.delegate = self;
 }
 return _textfield;
}
- (instancetype)initwithstyle:(uitableviewcellstyle)style reuseidentifier:(nsstring *)reuseidentifier{
 if (self = [super initwithstyle:style reuseidentifier:reuseidentifier]) {
  [self.contentview addsubview:self.textfield];
 }
 return self;
}
- (void)layoutsubviews{
 [super layoutsubviews];
 self.textfield.frame = (cgrect){{kdefaultspace, 0},{gxscreenwidth-2*kdefaultspace, cgrectgetheight(self.frame)}};
}

(2)xib创建,并拉线成属性:

代码中设置属性:

 self.textfidle.textalignment = nstextalignmentleft;
 self.textfidle.contentverticalalignment = uicontrolcontentverticalalignmentcenter;
 self.textfidle.borderstyle = uitextborderstylenone;
 self.textfidle.backgroundcolor = [uicolor lightgraycolor];

设置成功,如果还不成功的话,就要吧各个属性都测试一下,

注意:self.textfidle.clipstobounds = yes;这句话好像对偏移有影响,大家注意一下,我测试的是如果在上面的属性基础上加上这句话,文本就会偏移,去掉就没问题.

以上所述是小编给大家介绍的解决ios uitextfield 编辑时文本偏移问题，希望对大家有所帮助
