解決辦法：UIImageView默認(rèn)的UserInteractionEnabled是NO，把它修改成YES,或者可以直接在XCODE上面的view有個(gè)屬性勾選User Interaction Enabled遇到的場(chǎng)景(在滾動(dòng)視圖里面放一個(gè)圖片視圖，在圖片視圖上又放置一個(gè)按鍵，發(fā)現(xiàn)一直沒有響應(yīng)效果);

對(duì)應(yīng)到自己的項(xiàng)目里面，我用的是AFNetworking這套網(wǎng)絡(luò)請(qǐng)求包，需要改的是：AFURLResponseSerialization.m文件223行：self.acceptableContentTypes = [NSSetsetWithObjects:@"application/json", @"text/html",@"text/json",@"text/javascript", nil];加上@"text/html",部分，其實(shí)就是添加一種服務(wù)器返回的數(shù)據(jù)格式。

// NSArray --> NSMutableArray  NSMutableArray *myMutableArray = [myArray mutableCopy];  // NSMutableArray --> NSArray  NSArray *myArray = [myMutableArray copy];  

 //中間標(biāo)題   UILabel *navLabel = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 320, 44)];   navLabel.text = @"團(tuán)購(gòu)詳情";   navLabel.textColor = [UIColor whiteColor];   navLabel.font = [UIFont systemFontOfSize:18];   navLabel.textAlignment = NSTextAlignmentCenter;   self.navigationItem.titleView = navLabel;       //右邊收藏按鈕   UIButton *rightButton = [UIButton buttonWithType:UIButtonTypeCustom];   rightButton.frame = CGRectMake(0, 0, 20, 20);   [rightButton setBackgroundImage:LOAD_IMAGE(@"meishoucang") forState:UIControlStateNormal];   [rightButton addTarget:self action:@selector(doShouCang) forControlEvents:UIControlEventTouchUpInside];   UIBarButtonItem *rightItem = [[UIBarButtonItem alloc] initWithCustomView:rightButton];   self.navigationItem.rightBarButtonItem = rightItem;       //左邊返回按鈕   UIButton *fanHuiButton = [UIButton buttonWithType:UIButtonTypeCustom];   fanHuiButton.frame = CGRectMake(0, 0, 30, 40);   [fanHuiButton setBackgroundImage:LOAD_IMAGE(@"fanhuijiantou") forState:UIControlStateNormal];   [fanHuiButton addTarget:self action:@selector(doFanHui) forControlEvents:UIControlEventTouchUpInside];   UIBarButtonItem *leftItem = [[UIBarButtonItem alloc] initWithCustomView:fanHuiButton];   self.navigationItem.leftBarButtonItem = leftItem;導(dǎo)航條上的title字體， 字號(hào) 可以這么定義，完全使用系統(tǒng)的 [self.navigationController.navigationBar setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:       [UIColor colorWithRed:1.0/255 green:1.0/255 blue:1.0/255 alpha:1], UITextAttributeTextColor,[UIColor clearColor],UITextAttributeTextShadowColor,[UIFont systemFontOfSize:20],UITextAttributeFont,nil]];

self.tableView.tableFooterView = [[UIView alloc] init];

//隱藏頭部左邊的返回self.navigationItem.hidesBackButton=YES;//隱藏頭部右邊self.navigationItem.rightBarButtonItem.customView.hidden=YES;

UIImage *image=[UIImage imageNamed:@"AppBg"];self.collectionView.layer.contents=(id)image.CGImage;

UIWindow *window = [UIApplication sharedApplication].keyWindow;    window.rootViewController = [[HVWTabBarViewController alloc] init];

 IntroductoryViewController *introductory=[mainStoryboard instantiateViewControllerWithIdentifier:@"introductoryview"];        UINavigationController *rootNavigationController=[[UINavigationController alloc] initWithRootViewController:introductory];            self.window.rootViewController=rootNavigationController;主要問題是a跳轉(zhuǎn)到b,然后b放一個(gè)授權(quán)新浪微博的按鍵，增加一個(gè)UINavigationController，然后在a跳轉(zhuǎn)到b時(shí)用nav跳轉(zhuǎn)：    UIStoryboard *mainStoryboard=[UIStoryboard storyboardWithName:@"Main" bundle:nil];    LoginViewController* loginviewControll=[mainStoryboard instantiateViewControllerWithIdentifier:@"loginviewcontroller"];    [self.navigationController pushViewController:loginviewControll  animated:YES];

是因?yàn)橹貜?fù)引入libTCWeiboSDK這個(gè)類庫(kù)，TARGETS-PROJECT-Build Phases-Link Binary With Libraries中，有三個(gè)libTcweiboSDK,可以刪除libTCWeiboSDK-I386.a

注意：NSUserDefaults支持的數(shù)據(jù)類型有NSString、 NSNumber、NSDate、 NSArray、NSDictionary、BOOL、NSInteger、NSFloat等系統(tǒng)定義的數(shù)據(jù)類型。本次遇到的問題：當(dāng)NSDictionary里面的值為null時(shí)，要寫入NSUserDefaults會(huì)報(bào)異常（attempt to insert non-property list object）；解決方式：把字典中的值進(jìn)行過濾處理，為空的轉(zhuǎn)化成字符串的空值；代碼如下(創(chuàng)建一個(gè)擴(kuò)展類):@implementation NSDictionary(Common)-(NSDictionary *) changeDictionaryNotNill{    NSMutableDictionary *muResult=[[NSMutableDictionary alloc]init];    NSEnumerator *enumerator=[self keyEnumerator];    id key;    while ((key=[enumerator nextObject])) {        id value=[self objectForKey:key];        if ((NSNull *)value==[NSNull null]) {            [muResult setObject:@"" forKey:key];        }        else        {            [muResult setObject:value forKey:key];        }    }    return muResult;}@end
