山寨QQ音乐的布局（二）终于把IOS6的UITableView拍扁了

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：

bubuko.com,布布扣

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:
