就是經過uitextfield的leftview來實現的,同時要設置leftviewmode。ui
若是設置左右邊距,須要再加上rightView功能spa
-(void)setTextFieldLeftPadding:(UITextField *)textField forWidth:(CGFloat)leftWidth { CGRect frame = textField.frame; frame.size.width = leftWidth; UIView *leftview = [[UIView alloc] initWithFrame:frame]; textField.leftViewMode = UITextFieldViewModeAlways; textField.leftView = leftview; }
