Adjusting frame of UIView. The easier way.

gistfile1.m

// UIView category

- (void)adjustFrame:(void(^)(CGRect *frame))block {
    CGRect frame = self.frame;
    block(&frame);
    self.frame = frame;
}

gistfile2.m

// Usage:

[view adjustFrame:^(CGRect *frame) {
    frame->origin.x = 10;
    frame->size = someSize;
}];

// + You never forget to re-assign the frame.
// + You don't need to create local variable.
// + The block argument is autocompleted and has its own scope.
// - You work with pointer to struct so use arrow `->` instead of dot.
