iPad – uinavigationController: Title Jump Adjustment Movies

#import "UINavigationBar+My.h"

@implementation UINavigationBar (My)

- (void)layoutSubviews { 
for (id obj in [self subviews]) {
 if ([NSStringFromClass([obj class]) isEqualToString:@"UINavigationItemView"])
 [(UIView *)obj setAutoresizingMask:UIViewAutoresizingFlexibleLeftMargin |UIViewAutoresizingFlexibleRightMargin];
 else if ([NSStringFromClass([obj class]) isEqualToString:@"UIButton"]) {
 if ([(UIButton *)obj center].x <([self center] .x / 2))
 [(UIButton *)obj setAutoresizingMask:UIViewAutoresizingFlexibleRightMargin];
 else
 [(UIButton *)obj setAutoresizingMask:UIViewAutoresizingFlexibleLeftMargin];
 }
 }

@end

I have an ipad application, I I want to hide and show a list of categories (a bit like a small view in a split view controller), and the main view that contains the UiNavigationController stack.

I want to resize the UINavigationController view to fill the entire screen when the category list is hidden, and shrink when the list is displayed.

I have it working, except at the beginning of the animation / When the frame is set in the submission block, the title of the navigation bar immediately jumps to its new offset.

Any ideas how to prevent the title from jumping?

I use it to fix the jump for title and right click in UINavigationBar.

#import "UINavigationBar+My.h"

@implementation UINavigationBar (My)
- (void)layoutSubviews {
for (id obj in [self subviews ]) {
 if ([NSStringFromClass([obj class]) isEqualToString:@"UINavigationItemView"])
 [(UIView *)obj setAutoresizingMask:UIViewAutoresizingFlexibleLeftMargin|UIViewAutoresizingFlexibleRightMargin];
 else if ([ NSStringFromClass([obj class]) isEqualToString:@"UIButton"]) {
 if ([(UIButton *)obj center].x <([self center].x / 2))
 [( UIButton *)obj setAutoresizingMask:UIViewAutoresizingFlexibleRightMargin];
 else
 [(UIButton *)obj setAutoresizingMask:UIViewAutoresizingFlexibleLeftMargin];
 }
}
@end< /pre> 
I hope it can help you ;-)
