小编sam*_*mir的帖子

当我从Github导入我的项目时,我有两个文件夹,它们在Xcode中显示为蓝色,但所有其他文件夹都是黄色的.这是怎么回事？

我有NSString这样的:@"3/15/2012 9:15 PM"我想把它转换成NSDate,我这样做了:

NSString *str =@"3/15/2012 9:15 PM";
NSDateFormatter *formatter = [[NSDateFormatter alloc]init];
[formatter setDateFormat:@"mm/dd/yyyy HH:mm"];
NSDate *date = [formatter dateFromString:];

NSLog(@"%@", date);  // date = null

谢谢你能帮我吗

我用soapui测试了我的Web服务(wsdl/soap).我有错误:http/log:错误400 BAD REQUEST.

请问我的wsdl可能有什么错误？

错误/日志:

我怎样才能使用字体:HelveticaNeue Regular在我的标签中？我可以用IB做到这一点,但是以编程方式看来它是不可能的.

HelveticaNeue-Medium是常规的还是HelveticaNeue？

我想了解:" self, dynamicType, Type".我有这个代码:

class SomeClass {}

let cls : SomeClass.Type = SomeClass.self
let cls2 : SomeClass = SomeClass()

是cls和cls2同样的事情？

有人可以提供一些关于差异的细节吗？谢谢

我有UISearchBar,UITableView,它返回一个Web服务NSMutableArray包含这样的对象:

//Food.h
Food : NSObject { 
    NSString *foodName;
    int idFood;
}

@property (nonatomic, strong) NSString *foodName;

而阵列:

Food *food1 = [Food alloc]initWithName:@"samsar" andId:@"1"];
Food *food2 = [Food alloc] initWithName:@"rusaramar" andId:@"2"];

NSSarray *array = [NSArray arrayWithObjects:food1, food2, nil];

如何使用名称以"sa"开头的对象过滤我的数组？

我的核心数据模型中有一个实体,如下所示:

@interface Selection : NSManagedObject

@property (nonatomic, retain) NSString * book_id;
@property (nonatomic, retain) NSString * contenu;
@property (nonatomic, retain) NSNumber * page_id;
@property (nonatomic, retain) NSNumber * nbrOfOccurences;
@property (nonatomic, retain) NSString * next;
@property (nonatomic, retain) NSString * previous;

我创建了很多Selections并将它们保存在Core Data中,现在我想删除一些带有一些标准的选择.例如,Selection如果匹配以下内容,我想删除一个对象:

content = test
page_id = 5
book_id = 1331313

我怎么能这样做？

我在iOS应用程序中使用SQLite,我使用FMDB作为包装器.这是我的数据库架构:

CREATE TABLE Offer (code TEXT PRIMARY KEY NOT NULL, name TEXT);

CREATE TABLE OffreMarket (codeOffer TEXT NOT NULL,
codeMarket TEXT NOT NULL,
FOREIGN KEY(codeOffer) REFERENCES Offer(code),
FOREIGN KEY(codeMarket) REFERENCES Market(code));

CREATE TABLE Market (code TEXT PRIMARY KEY NOT NULL, name TEXT);

我的模型对象:

@interface Offer : NSObject
@property (nonatomic,copy) NSString *code;
@property (nonatomic,copy) NSString *name;
@property (nonatomic,copy) NSArray *markets;
@end

@interface OffreMarket : NSObject
@property (nonatomic,copy) NSString *codeOffer;
@property (nonatomic,copy) NSString *codeMarket;
@end

@interface Market : NSObject
@property (nonatomic,copy) NSString …

我正在尝试在iOS 5.1.1中运行的iPad中安装iOS应用程序.当我使用开发配置文件的Xcode启动它时,我收到以下错误:

Xcode无法在运行6.0之前版本的iOS版本的设备上安装或启动支持64位架构的应用程序.此配置支持通过iOS App Store分发,但在使用Xcode进行开发期间无法使用.要继续,请编辑"运行方案"操作,然后选择不包含64位体系结构的构建配置.

我试图通过删除arm64来改变建筑结构,但我有同样的错误.

我试图通过构建具有adhoc供应配置文件的ipa来安装testflight但重复相同的错误.

我如何在运行iOS 5.1.1的真实设备中测试我的应用程序,使用Xcode 5构建

我想用ASIHTTPRequest重现这个http标头调用.我怎么能这样做？
