1、在UITableViewController中,self.view就是self.tableView, 两个对象的指针地址是一样的 2、自定义类继承UITableViewCell, 重写父类方法 ...:(NSString *)reuseIdentifier { self = [super initWithStyle:style reuseIdentifier:reuseIdentifier]...[UIColor clearColor]; } /** Cell 被选中或者取消选中是都会被调用 如果是自定义Cell控件,所有的子控件都应该添加到contentView中 */ - (void...= [super init]){ NSLog(@"init ... 222 "); } return self; } - (instancetype)initWithFrame...:(CGRect)frame{ NSLog(@"initWithFrame ... 111"); if (self = [super initWithFrame:frame])
使用很普遍 UITableView *tableView = [[UITableView alloc] initWithFrame:frame style:UITableViewStyleGrouped...二、初始化 1、init initWithFrame:(CGRect)frame style:(UITableViewStyle)theStyle是最常用的初始化方式,那么Chameleon项目是怎么做的呢...- (id)initWithFrame:(CGRect)frame style:(UITableViewStyle)theStyle { if ((self=[super initWithFrame...:(NSString *)reuseIdentifier { if ((self=[self initWithFrame:CGRectMake(0,0,320,_UITableViewDefaultRowHeight...)])) { _style = style; _reuseIdentifier = [reuseIdentifier copy]; } return self
UIViewController { UITableView *theTableView; } 先建立Controller,注意是继承自...UIViewController而不是UITableViewController 实现类 - (id)init { if (self = [super init]) { self.view...= [[[UIView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame]] autorelease]; // Setup...:(NSString *)reuseIdentifier { if (self = [super initWithStyle:style reuseIdentifier:reuseIdentifier...image = [[UIImageView alloc] initWithImage:icon]; image.frame = CGRectMake(0, 0, 286, 68); //

:(CGRect)frame { self = [super initWithFrame:frame]; if (self) { self.carModelArray...:self.zoomOutBtn]; } return self; } 全局变量使用懒加载 需要提到的是当前位置的大头针的位置需要进行火星转码 //当前位置大头针 - (MyAnnotation..._zoomInBtn) { _zoomInBtn = [[UIButton alloc] initWithFrame:CGRectMake(CGRectGetWidth(self.frame...)-60, CGRectGetHeight(self.frame)*0.55, 50, 50)]; [_zoomInBtn setImage:[UIImage imageNamed:@"..._zoomOutBtn) { _zoomOutBtn = [[UIButton alloc] initWithFrame:CGRectMake(CGRectGetWidth(self.frame
:(NSString *)reuseIdentifier { if (self = [super initWithAnnotation:annotation reuseIdentifier:reuseIdentifier...; self.titleLabel = [[UILabel alloc] initWithFrame:CGRectMake(0, 5, CGRectGetWidth(self.frame), CGRectGetHeight...:CGRectMake(0, CGRectGetMaxY(self.titleLabel.frame), CGRectGetWidth(self.frame), CGRectGetHeight(self.frame...:(NSString *)reuseIdentifier { if (self = [super initWithAnnotation:annotation reuseIdentifier:reuseIdentifier...= title; [self.contentView setTitle:title forState:UIControlStateNormal]; } 为什么放一个Button,因为方便标题和背景设置
大家好,又见面了,我是全栈君 首先重写UITableViewCell初始化方法: - (id)initWithStyle:(UITableViewCellStyle...)style reuseIdentifier:(NSString *)reuseIdentifier { self = [super initWithStyle:style reuseIdentifier...:reuseIdentifier]; if (self) { // Initialization code self.photoView = [[UIImageView...self.ageLabel = [[UILabel alloc] initWithFrame:CGRectMake(200, 5, 40, 35)]; [self.contentView...= [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil]; if (self) { // Custom initialization

_historyTableView) { _historyTableView = [[UITableView alloc]initWithFrame:CGRectMake(achieveMargin...cell == nil) { cell = [[HTItemTableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier...:cellID]; } return cell; } - (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(...NSString *)reuseIdentifier{ self = [super initWithStyle:style reuseIdentifier:reuseIdentifier];...if (self) { } return self; } 5、点击事件 [ImageView setUserInteractionEnabled:YES]; UIGestureRecognizer

所以可以了解,标注这个概念在逻辑属性和视图上是分开的。...setCoordinate:(CLLocationCoordinate2D)newCoordinate; @end 二、创建一个系统标注大头针 - (void)viewDidLoad { [super... viewDidLoad]; //初始化地图 mapView =[[MKMapView alloc]initWithFrame:self.view.frame]; //设置代理...创建一个系统大头针对象 MKPinAnnotationView * view = [[MKPinAnnotationView alloc]initWithAnnotation:annotation reuseIdentifier...MKAnnotationView是标注的视图类,一会我们通过它来自定义我们自己的标注,先来看MKPinAnnotationView这个类,这个类继承于MKAnnotationView,是一个大头针视图类
