The UIView animation API results in different CAAnimations being added to the layer on iOS 7 and 8. Changing the bounds of a view like this:

[UIView animateWithDuration:0.3 
                 animations:^{
    self.myView.bounds = CGRectMake(0, 0, 100, 100); // was (0,0) (200, 200)
}];

will result in one animation for the bounds key path being added to the backing layer if you are running iOS 7:

The easiest way to start using the LLVM C++ API by example is to have LLVM generate the API usage for a given code sample. In this example it will emit the code required to rebuild the test.c sample by using LLVM:

$ clang -c -emit-llvm test.c -o test.ll
$ llc -march=cpp test.ll -o test.cpp

	NSDate *date = [NSDate new];

	NSDateFormatter *dateFormatter = [NSDateFormatter new];
	dateFormatter.locale = [NSLocale localeWithLocaleIdentifier:@"nl_NL"];
	dateFormatter.dateStyle = NSDateFormatterFullStyle;
	dateFormatter.formattingContext = NSFormattingContextDynamic; // this is the important setting

	NSString *dateString = [dateFormatter stringFromDate:date];

	NSString *s1 = [NSString stringWithFormat:@"Foo %@", dateString]; // "Foo dinsdag 13 december 2016"
