i have following code trying show pdf preview. words on ipad when trying on iphone dosnt work.

qlpreviewcontroller* preview = [[qlpreviewcontroller alloc] init];         preview.datasource = self;         [self dismissviewcontrolleranimated:yes completion:^{             [self presentviewcontroller:preview animated:yes completion:nil];         }];

the thread on iphone never makes line

[self presentviewcontroller:preview animated:yes completion:nil];

but works fine on ipad.. not sure at. appreaciated.

to access instances/variables (that declared outside of block) inside block, need declare instances/variables this: __block type identifier = initial value (optional) e.g, in case use __block qlpreviewcontroller* preview = [[qlpreviewcontroller alloc] init];
