moveStatusBar.gif

老規矩，先上效果圖一張。

廢話不多說，直接上代碼

    NSString *key = [[NSString alloc] initWithData:[NSData dataWithBytes:(unsigned char []){0x73, 0x74, 0x61, 0x74, 0x75, 0x73, 0x42, 0x61, 0x72} length:9] encoding:NSASCIIStringEncoding];
    id object = [UIApplication sharedApplication];
    UIView *statusBar;
    if ([object respondsToSelector:NSSelectorFromString(key)]) {
        statusBar = [object valueForKey:key];
    }
    [UIView animateWithDuration:.5 animations:^{
        statusBar.transform = CGAffineTransformMakeTranslation(x, y);
    }];

該方法可以再做側方庫時候使用，也可以在隱藏狀態欄而不想失去那20像素的高度時候使用。注意只是移動了transform，而狀態欄實際的frame并為發生改變。
