ios – 将图像添加到UIView

概述我正在尝试将图像添加到UIView,然后将其添加为UIViewController上的子视图. 这是我的代码： BlowView.h #import <UIKit/UIKit.h>@interface BlowView : UIView { UIImageView *stone;}@property (nonatomic, retain) UIImageView *stone; 我正在尝试将图像添加到UIVIEw,然后将其添加为UIVIEwController上的子视图.
这是我的代码：

BlowVIEw.h

#import <UIKit/UIKit.h>@interface BlowVIEw : UIVIEw {    UIImageVIEw *stone;}@property (nonatomic,retain) UIImageVIEw *stone;- (ID)init;@end

BlowVIEw.m

#import "BlowVIEw.h"@implementation BlowVIEw@synthesize stone;- (ID)init {    UIImageVIEw *logoVIEw = [[UIImageVIEw alloc] initWithImage:[UIImage imagenamed:@"Placard.png"]];    stone = logoVIEw;    [logoVIEw release];    UIImage *img = [UIImage imagenamed:@"Placard.png"];    CGRect frame = CGRectMake(0,img.size.wIDth,img.size.height);    [self initWithFrame:frame];    return self;}- (ID)initWithFrame:(CGRect)frame{    self = [super initWithFrame:frame];    if(self) {     }    return self;}- (voID)dealloc {    [stone release];    [super dealloc];}@end

BlowVIEwController.h

@class BlowVIEw;@interface BlowVIEwController : UIVIEwController {    BlowVIEw *avIEw;}@property (nonatomic,retain) BlowVIEw *avIEw;-(voID)setUpVIEw;@end

BlowVIEwController.m

#import "BlowVIEwController.h"#import "BlowVIEw.h"@implementation BlowVIEwController@synthesize avIEw;- (voID)setUpVIEw {    // Create the placard vIEw -- its init method calculates its frame based on its image    BlowVIEw *aVIEw2 = [[BlowVIEw alloc] init];    self.avIEw = aVIEw2;    [aVIEw2 release];    self.vIEw = self.avIEw;}- (voID)dIDReceiveMemoryWarning{    // Releases the vIEw if it doesn't have a supervIEw.    [super dIDReceiveMemoryWarning];    // Release any cached data,images,etc that aren't in use.}- (voID)vIEwDIDLoad {    [super vIEwDIDLoad];    [self setUpVIEw];    avIEw.center = self.vIEw.center;}- (voID)vIEwDIDUnload{    [super vIEwDIDUnload];    // Release any retained subvIEws of the main vIEw.    // e.g. self.myOutlet = nil;}- (BOol)shouldautorotatetoInterfaceOrIEntation:(UIInterfaceOrIEntation)interfaceOrIEntation{    // Return YES for supported orIEntations    return (interfaceOrIEntation == UIInterfaceOrIEntationPortrait);}- (voID)dealloc {    [avIEw release];    [super dealloc];}@end

无法弄清楚我哪里出错了.我没有错误..我得到的只是一个空白的白色碎片.任何帮助将受到高度赞赏:)

解决方法 在您的第一个代码段中,您尚未将图像添加到视图中,请在下面进行修改：

UIImageVIEw *logoVIEw = [[UIImageVIEw alloc] initWithImage:[UIImage imagenamed:@"Placard.png"]];stone = logoVIEw;[logoVIEw release];UIImage *img = [UIImage imagenamed:@"Placard.png"];CGRect frame = CGRectMake(0,img.size.height);[self initWithFrame:frame];// Here add your imageVIEw(stone) to your vIEw as a subvIEw[self addSubvIEw:stone];return self;
