iOS 定制手机通讯录（1）

我要写第一个自己写的iOS APP啦，都闪开闪开！

仍照着Homepwner扒，建个NMTel，先解决Empty Application模版的问题

把 Main.storyboard 和 LaunchScreen.xib 删掉，

把 Info.plist 里边的 Launch screen interface file base name 和 Main storyboard file base name两项删掉，

最后在AppDelegate的第一个方法里面添加代码：

self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];

self.window.backgroundColor = [UIColor whiteColor];

[self.window makeKeyAndVisible];

建UITableViewController类的BNRItemsViewController，在BNRItemsViewController实现初始化方法

- (instancetype)init

{

self = [super initWithStyle:UITableViewStylePlain];

return self;

}

- (instancetype)initWithStyle:(UITableViewStyle)style

{

return [self init];

}

在AppDelegate.m里边导入

#import “BNRItemsViewController.h”

再在第一个方法里加入

BNRItemsViewController *itemsViewController = [[BNRItemsViewController alloc] init];

self.window.rootViewController = itemsViewController;

这时运行应用，BNRItemsViewController中的view方法会调用loadView方法，得到一个空的UITableView对象。

下面写生成数据的对象，建立BNRItem，有4个实例变量，分别保存姓名、手机号、分机号、邮箱，一个实例方法initWithItemName用来传消息生成数据。

实现initWithItemName，并覆盖description方法。

BNRItem.h

#import 

@interface BNRItem : NSObject

{

NSString *_NMTelContactName;

NSString *_NMTelCellPhone;

NSString *_NMTelLandLine;

NSString *_NMTelContactEmail;

}

- (instancetype)initWithItemName:(NSString *)ContactName

NMTelCellPhone:(NSString *)CellPhone

NMTelLandLine:(NSString *)LandLine

NMTelContactEmail:(NSString *)ContactEmail;

@property (nonatomic, copy) NSString *NMTelContactName;

@property (nonatomic, copy) NSString *NMTelCellPhone;

@property (nonatomic, copy) NSString *NMTelLandLine;

@property (nonatomic, copy) NSString *NMTelContactEmail;

@end

BNRItem.m

#import “BNRItem.h”

@implementation BNRItem

- (NSString *)description

{

NSString *descriptionString =

[[NSString alloc] initWithFormat:@”%@ %@ %@ %@”,

self.NMTelContactName,

self.NMTelCellPhone,

self.NMTelLandLine,

self.NMTelContactEmail];

return descriptionString;

}

- (instancetype)initWithItemName:(NSString *)ContactName

NMTelCellPhone:(NSString *)CellPhone

NMTelLandLine:(NSString *)LandLine

NMTelContactEmail:(NSString *)ContactEmail

{

self = [super init];

if (self) {

_NMTelContactName = ContactName;

_NMTelCellPhone = CellPhone;

_NMTelLandLine = LandLine;

_NMTelContactEmail = ContactEmail;

}

return self;

}

@end

测试main.m，initWithItemName是有效的

#import 

#import “BNRItem.h”

int main(int argc, const char * argv[]) {

@autoreleasepool {

BNRItem *item = [[BNRItem alloc] init];

item.NMTelContactName = @”郑华恩”;

item.NMTelCellPhone = @”18801767597″;

item.NMTelLandLine = @”873″;

item.NMTelContactEmail = @”huaen@niumag.com”;

NSLog(@”%@”, item);

item = nil;

BNRItem *itemWithName = [[BNRItem alloc] initWithItemName:@”郑华恩”

NMTelCellPhone:@”18801767597″

NMTelLandLine:@”873″

NMTelContactEmail:@”huaen@niumag.com”];

NSLog(@”%@”, itemWithName);

}

return 0;

}

把BNRItem.h和BNRItem.m文件加入到NMTel
