UIScrollView set its contentOffset default? - ios

Question

I have a scroll view which consists of many of views. These views are placed in the view according to their dynamic size. There is also a delete button on each view which deletes the view from the scrollview, and replace the others accordingly.
But I have a problem, when I delete something scrollview does not stay where I deleted. One row up or down.
This is my deletion code:
-(void) redrawTheList:(id)sender :(NSString*) except{
int tempo = counterRow;
NSMutableDictionary *doctorTemp = [[NSMutableDictionary alloc]initWithDictionary:doctorAddition copyItems:YES];
for(int i = 0; i<=tempo;i++)
{
NSString *dictTempKey = [NSString stringWithFormat:#"row%d",i];
NSMutableArray * tempArray = [doctorTemp objectForKey:dictTempKey];
for(UIView * subview in tempArray)
{
for(UIView * subview2 in [subview subviews])
{
if([subview2 isKindOfClass:[UILabel class]])
{
if([((UILabel*)subview2).text isEqualToString:except])
{
counterRow = i;
tempile = i;
yAxis=5.0+(i*40.0);
}
}
}
}
}
for(int j=tempile;j<=tempo;j++)
{
NSString *dictTempKey2 = [NSString stringWithFormat:#"row%d",j];
NSMutableArray * tempArray = [doctorAddition objectForKey:dictTempKey2];
for(UIView * subview in tempArray)
{
[subview removeFromSuperview];
}
[doctorAddition removeObjectForKey:dictTempKey2];
}
for(int k=tempile;k<=tempo;k++)
{
NSString *dictTempKey3 = [NSString stringWithFormat:#"row%d",k];
NSMutableArray * tempArray2 = [doctorTemp objectForKey:dictTempKey3];
for(UIView * subview in tempArray2)
{
for(UIView * subview2 in [subview subviews])
{
if([subview2 isKindOfClass:[UILabel class]])
{
if(![((UILabel*)subview2).text isEqualToString:except])
{
[self createDoctorBox:((UILabel*)subview2).text];
}
}
}
}
}
}
CreateDoctorBox method;

Answer 1

its because when your function " createDoctorBox " call, there may be you have changed a scrollview properties. Please check there.
in your code [doctorList setContentSize:CGSizeMake(10, 36+(counterRow*41))]; its reset the contentOffset of the UIScrollView. if you want to stay on position of delete button, then below that line, set the delete button point as contentOffset of UIScrollView.
Example code:
[doctorList setContentSize:CGSizeMake(10, 36+(counterRow*41))];
doctorList.contentOffset:CGMakePoint(0,deleteBtn.frame.origin.y);
if its help then please vote for me.
