(I have been trying to send this to xcode-users, but for some reason it won't
go through, although it is not entirely off-topic for this list)
In this method:
- (void) drawBezelWithFrame:(NSRect)frame inView:(NSView *)controlView {
if (self.state == NSOnState) {
// If selected we need to draw the border new background for selection
(otherwise we will use default back color)
// Save current context
[[NSGraphicsContext currentContext] saveGraphicsState];
// Draw light vertical gradient
139 [kDMTabBarItemGradient drawInRect:frame angle:-90.0f];
// Draw shadow on the left border of the item
142 NSShadow *shadow = [[NSShadow alloc] init];
shadow.shadowOffset = NSMakeSize(1.0f, 0.0f);
shadow.shadowBlurRadius = 2.0f;
shadow.shadowColor = [NSColor darkGrayColor];
[shadow set];
[[NSColor blackColor] set];
CGFloat radius = 50.0;
NSPoint center = NSMakePoint(NSMinX(frame) - radius, NSMidY(frame));
NSBezierPath *path = [NSBezierPath bezierPath];
[path moveToPoint:center];
[path appendBezierPathWithArcWithCenter:center radius:radius
startAngle:-90.0f endAngle:90.0f];
[path closePath];
[path fill];
// shadow of the right border
shadow.shadowOffset = NSMakeSize(-1.0f, 0.0f);
[shadow set];
center = NSMakePoint(NSMaxX(frame) + radius, NSMidY(frame));
path = [NSBezierPath bezierPath];
[path moveToPoint:center];
[path appendBezierPathWithArcWithCenter:center radius:radius
startAngle:90.0f endAngle:270.0f];
[path closePath];
[path fill];
[shadow release];
// Restore context
[[NSGraphicsContext currentContext] restoreGraphicsState];
}
}
I am getting a warning that I wasn't getting before, in Xcode 4.3.3 LLVM 3.1:
"Potential leak of an object allocated on line 139", with two sub-warnings: 1)
"Method returns an Objective-C object with a +1 retain count" (highlights
kDMTabBarItemGradient), 2) "Object leaked: allocated object is not referenced
later in this execution path and has a retain count of +1" (highlights
"NSShadow *shadow" on line 142.
In Xcode 5, I was able to get rid of the warning by inserting the explicit
release of "shadow" (before it was autoreleased), but I can't seem to get Xcode
4.3 to do so. I tried relocating the shadow alloc/init before the save graphics
state, and the release after the restore, but that didn't work. In all cases it
trips on the gradient method call, which is odd, but it doesn't make any sense
to me in any case...
