I’ve spent some time trying to figure out why my pushed view controller was doing a funny animation instead the simple right-to-left animation. It seamed as if the view of the pushed view controller was treated as a layer and the setting of the views frame was done with an animation.

The problem turned out to be, that this pushing was done in an on complete of a dismissViewController:

[navigationController dismissViewControllerAnimated:YES completion:^{

    FunkyViewController *myFunkyViewController = [[FunkyViewController alloc] init];

    [navigationController pushViewController:myFunkyViewController animated:YES];

}];

The instantiation inside the completion block caused the loading of the view being done inside an animation transaction, which caused the setting of the frame as an animation…

Solution to this, just instantiating outside the completion block

FunkyViewController *myFunkyViewController = [[FunkyViewController alloc] init];

    [navigationController dismissViewControllerAnimated:YES completion:^{

    [navigationController pushViewController:myFunkyViewController animated:YES];

}];

Imagine you have a repeating animation created with the UIView block animation method and you want to stop.

So your creation looks like this:

[UIView animateWithDuration:2.0 delay:0.0 
options:(UIViewAnimationOptionRepeat|UIViewAnimationOptionAutoreverse)
animations:^{
    [myImageview setAlpha:1.0];
}completion:^(BOOL finished){
}];

You can just stop this animation by  commiting a fast animation to the final value you want to have, in my case alpha 0

[UIView beginAnimations:nil context:NULL];
[UIView setAnimationBeginsFromCurrentState:YES];
[UIView setAnimationDuration:0.1];
[UIView setAnimationCurve: UIViewAnimationCurveLinear];
[myImageview setAlpha:0.0];
[UIView commitAnimations];

source that didn’t work for me, as first guess because I am using an UIImageView:

Hi,

My previous post was a quick one to rescue a great post for editing font info with TTX FontTools.

I had the need of this tool because I was having troubles to make a UILabel getting the fontweight bold of a custom font of my current project. My project has a specific font with different weights, so different files and there was no way to make my UILabel getting a bold weight.

I tried to add a “-Bold” to the fontName, like this:

[UIFont fontWithName:@”Name of the font-Bold” size:15];

But this didn’t really work. With TTX I wanted to change the font name of family name so that I could just use a completely new one. What I realized with the xml generate from TTX is that the fontName wasn’t really the one displayed in FontBook window (on MAC).

In the xml try to use the font name under the item:

<CFFFont name=”MyFontName-Bold”>

This one is the that works with iOS labels!
