only the last label is displayed
In this following code I intend to programmatically add two labels in each row in a scrollable view. "label" gets added in the view with no problem but "infoLabel" I only see the last row. Has spent hours trying to figure out. Thanks for any help.
- (void)refreshList
{
// remove all the labels from the GUI
for (UILabel *label in scrollView.subviews)
[label removeFromSuperview];
RootModel *rm = [RootModel sharedModel];
float labelOffset = LABEL_SPACING; // reset the spacing
UILabel *i开发者_运维知识库nfoLabel = [[UILabel alloc] init ];
// repopulate the scroll view with Labels
for (UILabel *label in labels)
{
NSLog(@"%@", label.text);
CGRect labelFrame = label.frame; // fetch the frame of label
labelFrame.origin.x = LEFT_LABEL_SPACING; // set the x-coordinate
labelFrame.origin.y = labelOffset; // set the y-coordinate
labelFrame.size.width = scrollView.frame.size.width/3;
labelFrame.size.height = LABEL_HEIGHT; // set the height of Label
label.frame = labelFrame; // assign the new frame to Label
[scrollView addSubview:label]; // add Label as a subview
CGRect infolabelFrame = infoLabel.frame; // fetch the frame of label
infolabelFrame.origin.x = 10; // set the x-coordinate
infolabelFrame.origin.y = labelOffset; // set the y-coordinate
infolabelFrame.size.width = scrollView.frame.size.width/3;
infolabelFrame.size.height = LABEL_HEIGHT; // set the height of Label
infoLabel.frame = infolabelFrame; // assign the new frame to Label
NSString *key = label.text;
NSLog(@"%@", key);
infoLabel.text = [rm.rLevels valueForKey:key];
NSLog(@"%@ %@", infoLabel.text, key);
infoLabel.frame = infolabelFrame; // fetch the frame of label
[infoLabels addObject:infoLabel];
[scrollView addSubview:infoLabel]; // add Label as a subview
// increase the offset so the next button is added further down
labelOffset += LABEL_HEIGHT + LABEL_SPACING;
} // end for
} // end refreshList
You are creating a single instance of infoLabel
and resetting its frame
on each iteration of the loop. If you intend to have multiple labels, you will have to allocate and initialize a label on each iteration on the loop. Make sure you relinquish the ownership of the label you are allocating after you add it as a subview.
