易采站长站为您分析iOS开发之tableView点击下拉扩展与内嵌collectionView上传图片效果的相关资料,需要的朋友可以参考下
废话不多说了，直奔主题。
//需要的效果
1.设置window的根视图控制器为一个UITableViewController
#import "AppDelegate.h"
#import "YCTableViewController.h"
@interface AppDelegate ()
@end
@implementation AppDelegate
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
self.window = [[UIWindow alloc] initWithFrame:[UIScreen mainScreen].bounds];
self.window.backgroundColor = [UIColor whiteColor];
self.window.rootViewController = [[UINavigationController alloc] initWithRootViewController:[[YCTableViewController alloc] init]];
[self.window makeKeyAndVisible];
return YES;
}
2.UITableViewController
