I can't get my head around this issue: I have a UISearchBar
subclass that I'm using with a UISeachDisplayControlller
in a UITableViewController
that adds a button on the left side and makes the UISearchTextField
smaller so it can fit both views.
I set the frames manually in layoutSubviews
even tough I'm using AutoLayout
across the project.
The code looks something like this:
UIView *searchBarView = [self.subviews objectAtIndex:0];
[searchBarView addSubview:_annotationsButton];
for (UIView *subview in searchBarView.subviews) {
if ([subview isKindOfClass:[UITextField class]]) {
// Change the border color of the UISearchTextField
[subview.layer setBorderWidth:1.0];
[subview.layer setBorderColor:[UIColor colorFromHexString:@"#77848D"].CGColor];
[subview.layer setCornerRadius:2.0];
}
}
[self setBackgroundImage:[UIImage imageWithColor:[UIColor whiteColor]]];
self.separator = [[UIView alloc] initWithFrame:CGRectMake(0, self.bounds.size.height-1, self.bounds.size.width, 1)];
[self.separator setBackgroundColor:[UIColor colorFromHexString:@"#d6d0cc"]];
[searchBarView addSubview:self.separator];
The strange result looks like this:
As you can see, the bar is grayed out.
The layoutSubviews
method is the following:
- (void)layoutSubviews{
[super layoutSubviews];
UIView *searchBarView = [self.subviews objectAtIndex:0];
for (UIView *subview in searchBarView.subviews) {
if ([subview isKindOfClass:[UITextField class]]) {
CGRect textFieldFrame = [subview frame];
if (!subview.isFirstResponder) {
self.originalFrame = textFieldFrame;
CGRect newTextFieldRect = CGRectMake(self.originalFrame.origin.x + self.originalFrame.size.width /2,
self.originalFrame.origin.y,
self.originalFrame.size.width /2 - kPadding,
self.originalFrame.size.height);
[subview setFrame:newTextFieldRect];
CGRect annotationsButtonFrame = CGRectMake(kPadding,
self.originalFrame.origin.y,
self.originalFrame.size.width /2 - kPadding,
self.originalFrame.size.height);
[self.annotationsButton setFrame:annotationsButtonFrame];
[self.annotationsButton setHidden:NO];
}
else {
[self.annotationsButton setHidden:YES];
}
}
}
[self.separator setFrame:CGRectMake(0, self.bounds.size.height-1, self.bounds.size.width, 1)];
}
In this method, I just adjust the frames of the UISearchBarTextField
and _annotationsButton so they do not overlap.
