IOS客户端Coding项目记录(五)

1:统一修改导航栏的样式，在 AppDelegate.m中

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions

{

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

    // Override point for customization after application launch.

    self.window.backgroundColor = [UIColor whiteColor];

    //设置导航条样式

    [self customizeInterface];

    if ([Login isLogin]) {

        [self setupTabViewController];

    }else{

        [UIApplication sharedApplication].applicationIconBadgeNumber = ;

        [self setupLoginViewController];

    }

    [self.window makeKeyAndVisible];

    return YES;

}

- (void)customizeInterface {

    //设置Nav的背景色和title色

    UINavigationBar *navigationBarAppearance = [UINavigationBar appearance];

    NSDictionary *textAttributes = nil;

    if (NSFoundationVersionNumber > NSFoundationVersionNumber_iOS_6_1) {

        [navigationBarAppearance setTintColor:[UIColor whiteColor]];//返回按钮的箭头颜色

        [[UITextField appearance] setTintColor:[UIColor colorWithHexString:@"0x3bbc79"]];//设置UITextField的光标颜色

        [[UITextView appearance] setTintColor:[UIColor colorWithHexString:@"0x3bbc79"]];//设置UITextView的光标颜色

        [[UISearchBar appearance] setBackgroundImage:[UIImage imageWithColor:[UIColor colorWithHexString:@"0xe5e5e5"]] forBarPosition: barMetrics:UIBarMetricsDefault];

        textAttributes = @{

                           NSFontAttributeName: [UIFont boldSystemFontOfSize:kNavTitleFontSize],

                           NSForegroundColorAttributeName: [UIColor whiteColor],

                           };

    } else {

#if __IPHONE_OS_VERSION_MIN_REQUIRED < __IPHONE_7_0

        [[UISearchBar appearance] setBackgroundImage:[UIImage imageWithColor:[UIColor colorWithHexString:@"0xe5e5e5"]]];

        textAttributes = @{

                           UITextAttributeFont: [UIFont boldSystemFontOfSize:kNavTitleFontSize],

                           UITextAttributeTextColor: [UIColor whiteColor],

                           UITextAttributeTextShadowColor: [UIColor clearColor],

                           UITextAttributeTextShadowOffset: [NSValue valueWithUIOffset:UIOffsetZero],

                           };

#endif

    }

    [navigationBarAppearance setBackgroundImage:[UIImage imageWithColor:[UIColor colorWithHexString:@"0x28303b"]] forBarMetrics:UIBarMetricsDefault];

    [navigationBarAppearance setTitleTextAttributes:textAttributes];

}

其中上面的版本判断：

FOUNDATION_EXPORT double NSFoundationVersionNumber;

#if TARGET_OS_IPHONE

#define NSFoundationVersionNumber_iPhoneOS_2_0    678.24

#define NSFoundationVersionNumber_iPhoneOS_2_1  678.26

#define NSFoundationVersionNumber_iPhoneOS_2_2  678.29

#define NSFoundationVersionNumber_iPhoneOS_3_0  678.47

#define NSFoundationVersionNumber_iPhoneOS_3_1  678.51

#define NSFoundationVersionNumber_iPhoneOS_3_2  678.60

#define NSFoundationVersionNumber_iOS_4_0  751.32

#define NSFoundationVersionNumber_iOS_4_1  751.37

#define NSFoundationVersionNumber_iOS_4_2  751.49

#define NSFoundationVersionNumber_iOS_4_3  751.49

#define NSFoundationVersionNumber_iOS_5_0  881.00

#define NSFoundationVersionNumber_iOS_5_1  890.10

#define NSFoundationVersionNumber_iOS_6_0  992.00

#define NSFoundationVersionNumber_iOS_6_1  993.00

#define NSFoundationVersionNumber_iOS_7_0 1047.20

#define NSFoundationVersionNumber_iOS_7_1 1047.25

#endif

2:判断一张view 是否被加载过用 nil == view.superview

        if (nil == view.superview) {     //判断一个view 是否被加载过    如果被加载过，它的superview就不会是nil

            CGRect frame = scrollView0.frame;

            frame.origin.x = frame.size.width * page;

            frame.origin.y = ;

            view.frame = frame;

            [scrollView0 addSubview:view];

        }

3:百度地图初始化坐标范围

- (void)viewDidLoad {

    [super viewDidLoad];

    [UIApplication sharedApplication].applicationIconBadgeNumber =;

    _mapView=[[BMKMapView alloc] initWithFrame:CGRectMake(, , , )];

    BMKCoordinateRegion region; ////表示范围的结构体

    region.center.latitude  = 24.27;// 中心中

    region.center.longitude = 118.06;

    region.span.latitudeDelta = 0.1;//经度范围（设置为0.1表示显示范围为0.2的纬度范围）

    region.span.longitudeDelta = 0.1;//纬度范围

    [_mapView setRegion:region];

    [self.baiduView addSubview:_mapView];

}

自定义大头针的图片：

- (BMKAnnotationView *)mapView:(BMKMapView *)mapView viewForAnnotation:(id <BMKAnnotation>)annotation

{

    if ([annotation isKindOfClass:[BMKPointAnnotation class]]) {

        BMKPinAnnotationView *newAnnotationView = [[BMKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:@"myAnnotation"];

        newAnnotationView.pinColor = BMKPinAnnotationColorPurple;

        newAnnotationView.animatesDrop = YES;// 设置该标注点动画显示

        newAnnotationView.image = [UIImage imageNamed:@"iphone"];   //把大头针换成别的图片

        return newAnnotationView;

    }

    return nil;

}

4:隐藏键盘

当前视图上有多个uitextfield时，来隐藏键盘， 先遍历视图的所有子视图来 如果是UITextField就将其设为非第一响应 当然，如果要隐藏子视图上的UITextField的话可以进一步判断view的subviews的个数，如果大于1则遍历view的子视图，然后作类似操作

//隐藏键盘  当前视图上有多个uitextfield

for(UIView *view in [self.view subviews])

{

     if(view is kindofclass:[UITextField Class])

    {

             [view resignfirstrespond];

     }

}

直接用 [self.view endEditing:NO]

直接取消当前Window上的各种view的键盘 [[[UIApplication sharedApplication] keyWindow] endEditing:YES];

或者使用如下代码

- (BOOL)textFieldShouldBeginEditing:(UITextField *)textField

{

UITapGestureRecognizer *tapGestureRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(done:)];

tapGestureRecognizer.numberOfTapsRequired = ;

[self.view addGestureRecognizer: tapGestureRecognizer];   //只需要点击非文字输入区域就会响应hideKeyBoard

return YES;

}

5:UIView中的坐标转换

// 将像素point由point所在视图转换到目标视图view中，返回在目标视图view中的像素值

- (CGPoint)convertPoint:(CGPoint)point toView:(UIView *)view;

// 将像素point从view中转换到当前视图中，返回在当前视图中的像素值

- (CGPoint)convertPoint:(CGPoint)point fromView:(UIView *)view;

// 将rect由rect所在视图转换到目标视图view中，返回在目标视图view中的rect

- (CGRect)convertRect:(CGRect)rect toView:(UIView *)view;

// 将rect从view中转换到当前视图中，返回在当前视图中的rect

- (CGRect)convertRect:(CGRect)rect fromView:(UIView *)view;

例把UITableViewCell中的subview(btn)的frame转换到 controllerA中

// controllerA 中有一个UITableView, UITableView里有多行UITableVieCell，cell上放有一个button

// 在controllerA中实现:

CGRect rc = [cell convertRect:cell.btn.frame toView:self.view];

或

CGRect rc = [self.view convertRect:cell.btn.frame fromView:cell];

// 此rc为btn在controllerA中的rect

或当已知btn时：

CGRect rc = [btn.superview convertRect:btn.frame toView:self.view];

或

CGRect rc = [self.view convertRect:btn.frame fromView:btn.superview];

比如：

CGPoint origin = [self convertPoint:CGPointZero toView:[UIApplication sharedApplication].keyWindow];

把self的0点坐标系，放到keyWindow的坐标系换算一下，获得一个“绝对的”坐标

一个在父控件中的坐标为0,  其实父控件本来有坐标200,  通过上面可以获得这个200,200值

6:弹出一个视图，并有一个背影的视图（大体代码）

- (UIView *)myTapBackgroundView{

    if (!_myTapBackgroundView) {

        _myTapBackgroundView = ({

            UIView *view = [[UIView alloc] initWithFrame:kScreen_Bounds];

            view.backgroundColor = [UIColor clearColor];

            UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(changeShowing)];

            [view addGestureRecognizer:tap];

            view;

        });

    }

    return _myTapBackgroundView;

}

- (UIView *)myContentView{

    if (!_myContentView) {

        _myContentView = ({

            UIView *view = [[UIView alloc] initWithFrame:CGRectZero];

            view.backgroundColor = [UIColor whiteColor];

            view;

        });

    }

    return _myContentView;

}

- (void)changeShowing{

    [kKeyWindow endEditing:YES];

    if (!_myContentView) {//未载入过

        [self loadUIElement];

    }

    CGPoint origin = [self convertPoint:CGPointZero toView:kKeyWindow];

    CGFloat contentHeight = self.isShowing? : kCodeBranchTagButton_ContentHeight;

    if (self.isShowing) {//隐藏

        self.enabled = NO;

        [UIView animateWithDuration:0.3 animations:^{

            self.myTapBackgroundView.backgroundColor = [UIColor colorWithWhite: alpha:];

            self.myContentView.alpha = ;

            self.myContentView.frame = CGRectMake(, origin.y-contentHeight, kScreen_Width, contentHeight);

            self.imageView.transform = CGAffineTransformRotate(self.imageView.transform, DEGREES_TO_RADIANS());

        } completion:^(BOOL finished) {

            [self.myTapBackgroundView removeFromSuperview];

            [self.myContentView removeFromSuperview];

            self.enabled = YES;

            self.isShowing = NO;

        }];

    }else{//显示

        self.myContentView.frame = CGRectMake(, origin.y, kScreen_Width, );

        [kKeyWindow addSubview:self.myTapBackgroundView];

        [kKeyWindow addSubview:self.myContentView];

        self.enabled = NO;

        [UIView animateWithDuration:0.3 animations:^{

            self.myTapBackgroundView.backgroundColor = [UIColor colorWithWhite: alpha:0.2];

            self.myContentView.alpha = 1.0;

            self.myContentView.frame = CGRectMake(, origin.y-contentHeight, kScreen_Width, contentHeight);

            self.imageView.transform = CGAffineTransformRotate(self.imageView.transform, DEGREES_TO_RADIANS());

        } completion:^(BOOL finished) {

            self.enabled = YES;

            self.isShowing = YES;

        }];

    }

}

其中：#define kScreen_Bounds [UIScreen mainScreen].bounds

#define kKeyWindow [UIApplication sharedApplication].keyWindow

运用在项目中一个下拉菜单：

[view addGestureRecognizer:tap];

view;

self.myContentView.frame = CGRectMake(0,0, SCREEN_WIDTH, contentHeight);

} completion:^(BOOL finished) {

[self.myTapBackgroundView removeFromSuperview];

[self.myContentView removeFromSuperview];

self.isShowing = NO;

}];

}else{//显示
