IOS应用开发中UITableView的应用十分广泛，但是IOS7神一样的把UITableView拍扁了，这样一来IOS6的UITableView不干了，就吵着也要被拍扁，那好吧我今天就成全了你。。。
继上回书说道初步实现了一个QQ音乐的框架，但这远远不够，我是一个追求细节的人（就像锤子科技的老罗一样），怎么可能就这就结束了呢，下一步实现以下登陆的ModalView，比较简单没啥可说的直接上代码：
1 UIColor *normalColor = [UIColor colorWithRed:28/255.0 green:191/255.0 blue:97/255.0 alpha:1]; //按钮默认状态的绿色
2 UIColor *selectedColor = [UIColor colorWithRed:185/255.0 green:227/255.0 blue:214/255.0 alpha:1]; //按钮点击状态的淡绿色
3 CGFloat navigationY = 0;
4 if (IOS_7) {
5 navigationY = 20;
6 }
7
8
9 UINavigationBar *loginNavigationBar = [[UINavigationBar alloc] initWithFrame:CGRectMake(0, navigationY, 320, 44)]; //UINavigationBar的位置
10 UIButton *cancelButton = [UIButton buttonWithType:UIButtonTypeSystem];
11 [cancelButton setFrame:CGRectMake(0, 0, 40, 40)];
12 [cancelButton setTitle:@"取消" forState:UIControlStateNormal];
13 [cancelButton setTitleColor:normalColor forState:UIControlStateNormal];
14 [[cancelButton titleLabel] setFont:[UIFont systemFontOfSize:18]];
15 [cancelButton setTitleColor:selectedColor forState:UIControlStateHighlighted];
16 [cancelButton addTarget:self action:@selector(dismissView) forControlEvents:UIControlEventTouchUpInside];
17 UIBarButtonItem *cancelItem = [[UIBarButtonItem alloc] initWithCustomView:cancelButton]; //初始化取消按钮
18
19
20 UIButton *loginButton = [UIButton buttonWithType:UIButtonTypeSystem];
21 [loginButton setFrame:CGRectMake(0, 0, 40, 40)];
22 [loginButton setTitle:@"登陆" forState:UIControlStateNormal];
23 [loginButton setTitleColor:normalColor forState:UIControlStateNormal];
24 [[loginButton titleLabel] setFont:[UIFont systemFontOfSize:18]];
25 [loginButton setTitleColor:selectedColor forState:UIControlStateHighlighted];
26 [loginButton addTarget:self action:@selector(loginAction) forControlEvents:UIControlEventTouchUpInside];
27 UIBarButtonItem *loginItem = [[UIBarButtonItem alloc] initWithCustomView:loginButton]; //初始化登陆按钮
28
29 UIImage *image = [UIImage imageNamed:@"input_login_line"];
30
31 UIImageView *userLineView = [[UIImageView alloc] initWithImage:image];
32 UIImageView *passwordLineView = [[UIImageView alloc] initWithImage:image]; //输入框下面的绿线
33
34 UITextField *userTextField = [[UITextField alloc] initWithFrame:CGRectMake(30, 100+navigationY, 260, 30)];
35 [userTextField setPlaceholder:@"QQ号/手机/邮箱"];
36 [userTextField setClearButtonMode:UITextFieldViewModeWhileEditing];
37 [userTextField setKeyboardType:UIKeyboardTypeNumbersAndPunctuation];
38 [userTextField setReturnKeyType:UIReturnKeyNext];
39 [userLineView setFrame:CGRectMake(30, 131+navigationY, 260, 1)];
40
41 UITextField *passwordTextField = [[UITextField alloc] initWithFrame:CGRectMake(30, 140+navigationY, 260, 30)];
42 [passwordTextField setPlaceholder:@"密码"];
43 [passwordTextField setClearButtonMode:UITextFieldViewModeWhileEditing];
44 [passwordTextField setKeyboardType:UIKeyboardTypeASCIICapable];
45 [passwordTextField setReturnKeyType:UIReturnKeyDone];
46 [passwordLineView setFrame:CGRectMake(30, 171+navigationY, 260, 1)];
47
48 UILabel *regStr = [[UILabel alloc] initWithFrame:CGRectMake(75, 180+navigationY, 110, 30)];
49 [regStr setText:@"没有账号？点击这里"];
50 [regStr setFont:[UIFont systemFontOfSize:12]];
51 [regStr setTextColor:[UIColor darkGrayColor]];
52 UILabel *greenStr = [[UILabel alloc] initWithFrame:CGRectMake(184, 180+navigationY, 60, 30)];
53 [greenStr setText:@"快速注册"];
54 [greenStr setFont:[UIFont systemFontOfSize:12]];
55 [greenStr setTextColor:normalColor];
56
57 UINavigationItem *navigationItem = [[UINavigationItem alloc] initWithTitle:@"登陆"];
58 [navigationItem setLeftBarButtonItem:cancelItem];
59 [navigationItem setRightBarButtonItem:loginItem];
60 [loginNavigationBar pushNavigationItem:navigationItem animated:YES];
61
62
63
64 [self.view addSubview:loginNavigationBar];
65 [self.view addSubview:userTextField];
66 [self.view addSubview:userLineView];
67 [self.view addSubview:passwordTextField];
68 [self.view addSubview:passwordLineView];
69 [self.view addSubview:regStr];
70 [self.view addSubview:greenStr];
总结起来就是一个UINavigationBar，UINavigationBar上面有两个按钮，两个UITextField。只得说的事这个按钮，IOS7中把按钮的衣服扒掉了，这就直接导致我也要让IOS6的按钮也裸奔：
1 [[UINavigationBar appearance] setBackgroundImage:[UIImage imageWithColor:[UIColor whiteColor] size:CGSizeMake(1, 44)] forBarMetrics:UIBarMetricsDefault];
好了然后就没什么特别的了改改UITextField关联的键盘字体大小颜色什么的，效果图如下：
下面就是硬菜了，QQ音乐的界面UITableView采用的是UITableViewStyleGrouped类型的，但是在IOS6下UITableView有一个讨厌的灰不拉几的背景，我要把背景变为白色，使用如下代码：
1 [tableView setBackgroundColor:[UIColor whiteColor]];
2 [tableView setBackgroundView:nil];
这样UITableView在IOS6中那讨厌的背景就没有了，但是UITableViewCell默认是圆角的很恶心，干掉：
1 UIView *tempView = [[UIView alloc] init];
2 [cell setBackgroundView:tempView];
还要去掉cell点击时的圆角：
1 cell.selectedBackgroundView = [[UIView alloc] initWithFrame:cell.frame];
2 cell.selectedBackgroundView.backgroundColor = [UIColor lightGrayColor];
这里可以不用设置颜色的，而且现在这个颜色挺难看的，我还要继续修改
还有个问题IOS6的UITableViewCell默认不是与屏幕同宽的，需要自定义一个UItableViewCell复写 layoutSubviews
方法，代码如下：
1 - (void) layoutSubviews {
2 [super layoutSubviews];
3 self.backgroundView.frame = CGRectMake(0, 0, 320, 44);
4 self.selectedBackgroundView.frame = CGRectMake(0, 0, 320, 44);
5 }
好了这样初步的适配完了，当然还有细节没有做到，继续学习吧，下面是我的音乐视图控制器的完整代码:
