****UITextField****
@interface GOVFeedTextField : UITextField
@end
@implementation GOVFeedTextField
// 占位文字与输入框前距离
-(CGRect)textRectForBounds:(CGRect)bounds{
return CGRectInset(bounds, LAYOUT_SIZESCALE_PORTRAIT(20, 20).width, 0);
}
// 光标的距离设置
-(CGRect)editingRectForBounds:(CGRect)bounds{
return CGRectInset(bounds, LAYOUT_SIZESCALE_PORTRAIT(20, 20).width, 0);
}
@end
在创建的textfield那再调用
[textField textRectForBounds:CGRectMake(5, titleLabel.frame.size.height + titleLabel.frame.origin.y, LAYOUT_SCREENSIZE_P.width - 2 * 15, 39)];
[textField editingRectForBounds:CGRectMake(5, titleLabel.frame.size.height + titleLabel.frame.origin.y, LAYOUT_SCREENSIZE_P.width - 2 * 15, 39)];
****UITextView的placehodler设置****
UITextView *suggestView = [[UITextView alloc]initWithFrame:CGRectMake(15, 40, LAYOUT_SCREENSIZE_P.width - 2*15, LAYOUT_SIZESCALE_PORTRAIT(314, 314).height)];
suggestView.delegate = self;
suggestView.text = @"我是占位文字";
遵循代理,并实现代理方法
#pragma UITextViewDelegate
- (void)textViewDidBeginEditing:(UITextView *)textView{
if ([textView.text isEqualToString:@"我是占位文字"]) {
textView.text = @"";
textView.textColor = [UIColor redColor];
}
}
-(void)textViewDidEndEditing:(UITextView *)textView{
if ([textView.text isEqualToString:@""]) {
textView.text = @"我是占位文字";
textView.textColor = [UIColor lightGrayColor];
}
}
