1、滑動的時候隱藏navigation ?bar

navigationController.hidesBarsOnSwipe = Yes;

?2、消除導航條返回鍵自帶的title

[[UIBarButtonItem appearance] setBackButtonTitlePositionAdjustment:UIOffsetMake(0, -60)forBarMetrics:UIBarMetricsDefault];

?3、將導航條變得透明而不模糊

[self.navigationController.navigationBar setBackgroundImage:[UIImage new]forBarMetrics:UIBarMetricsDefault]; self.navigationController.navigationBar .shadowImage = [UIImage new]; self.navigationController.navigationBar .translucent = YES;

?4、拉伸圖片不變形

[[UIImage imageNamed:@""] stretchableImageWithLeftCapWidth:10 topCapHeight:10]; [[UIImage imageNamed:@""] resizableImageWithCapInsets:UIEdgeInsetsMake(10, 10, 10, 10)];

?5、gif圖片顯示優化

FLAnimatedImage可以幫你完成GIF的顯示處理。解決GIF顯示卡頓的情況。

FLAnimatedImage *image = [FLAnimatedImage animatedImageWithGIFData:[NSData dataWithContentsOfURL:[NSURL URLWithString:@"https://upload.wikimedia.org/wikipedia/commons/2/2c/Rotating_earth_%28large%29.gif"]]]; FLAnimatedImageView *imageView = [[FLAnimatedImageView alloc] init]; imageView.animatedImage = image; imageView.frame = CGRectMake(0.0, 0.0, 100.0, 100.0); [self.view addSubview:imageView];

?6、CollectionView實現tableview的懸停header

CSStickyHeaderFlowLayout可以解決您的疑問。

#import "CSStickyHeaderFlowLayout.h" - (void)viewDidLoad {[super viewDidLoad]; // Locate your layout CSStickyHeaderFlowLayout *layout = (id)self.collectionViewLayout; if ([layout isKindOfClass:[CSStickyHeaderFlowLayout class]]) { layout.parallaxHeaderReferenceSize = CGSizeMake(320, 200);} }- (UICollectionReusableView *)collectionView:(UICollectionView *)collectionView viewForSupplementaryElementOfKind:(NSString *)kind atIndexPath:(NSIndexPath *)indexPath { // Check the kind if it's CSStickyHeaderParallaxHeader if ([kind isEqualToString:CSStickyHeaderParallaxHeader]) { UICollectionReusableView *cell = [collectionView dequeueReusableSupplementaryViewOfKind:kind withReuseIdentifier:@"header" forIndexPath:indexPath];return cell; } }
