下午好。ICarusel 我在我的应用程序中使用。我有一个作为图像视图加载的图像。图像被准确地放置在中心。请告诉我如何在不移动其余内容的情况下将图像最多移动到 50 像素？
像这样创建视图的方法：
- (UIView *)carousel:(iCarousel *)carousel viewForItemAtIndex:(NSUInteger)index reusingView:(UIView *)view
{
NSString *docDir = [NSHomeDirectory() stringByAppendingPathComponent:@"Library/Caches"];
NSDictionary *myDic =[magazinesInfo objectAtIndex:index];
//Resize image
UIImage *img = [UIImage imageWithImage:[UIImage imageWithContentsOfFile:[NSString stringWithFormat:@"%@/%@_img.png",docDir,[myDic objectForKey:@"title"]]] scaledToSize:CGSizeMake(375,510)];
UIImageView *romb = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 118, 135)];
UIImageView *faceImage = [[UIImageView alloc] initWithFrame:CGRectMake(0,0,768,1004)];
UIImage *dwImage = [UIImage imageNamed:@"button.png"];
UIImage *readImage = [UIImage imageNamed:@"read_button.png"];
UIImage *deleteImage = [UIImage imageNamed:@"delete_button.png"];
if(view ==nil)
{
UIButton *myDownloadButton = [[UIButton alloc] initWithFrame:CGRectMake(0, 0, 100, 100)];
[myDownloadButton setBackgroundColor:[UIColor blackColor]];
[myDownloadButton setHidden:YES];
romb.image = [UIImage imageNamed:@"romb.png"];
view = [[UIView alloc]initWithFrame:CGRectMake(0, 0, 768, 1004)];
[view setBackgroundColor:[UIColor blackColor]];
view = faceImage;
faceImage.image = nil;
((UIImageView *)view).image = nil;
view.contentMode = UIViewContentModeCenter;
//Magazine number
myLabel = [[UILabel alloc] initWithFrame:CGRectMake(345, 85, 75, 29)];
myLabel.backgroundColor = [UIColor clearColor];
myLabel.textAlignment = NSTextAlignmentCenter;
[myLabel setFont:[UIFont fontWithName:@"OpenSans-Light" size:36.0f]];
myLabel.textColor = [UIColor whiteColor];
myLabel.tag = 1;
//Magazine name
nameMag = [[UILabel alloc] initWithFrame:CGRectMake(-65, 450, 100, 100)];
nameMag.backgroundColor = [UIColor yellowColor];
nameMag.textAlignment = NSTextAlignmentCenter;
[nameMag setFont:[UIFont fontWithName:@"OpenSans-Light" size:30.0f]];
nameMag.textColor = [UIColor blackColor];
nameMag.tag = 3;
//Date
dateMag = [[UILabel alloc] initWithFrame:CGRectMake(-67, 500, 500, 30)];
dateMag.backgroundColor = [UIColor greenColor];
dateMag.textAlignment = NSTextAlignmentCenter;
[dateMag setFont:[UIFont fontWithName:@"OpenSans-Light" size:20.0f]];

dateMag.tag = 4;
//Download button

[downloadButton setBackgroundImage:dwImage forState:UIControlStateNormal];
[downloadButton addTarget:self action:@selector(pressDownload:) forControlEvents:UIControlEventTouchUpInside];
downloadButton.tag = 5;
//Read button
readButton = [[UIButton alloc] initWithFrame:CGRectMake(250, 750, 128, 37)];
[readButton setBackgroundImage:readImage forState:UIControlStateNormal];
[readButton addTarget:self action:@selector(readMag:) forControlEvents:UIControlEventTouchUpInside];
readButton.hidden=YES;
readButton.tag = 8;
//Delete button
deleteButton = [[UIButton alloc] initWithFrame:CGRectMake(400, 750, 128, 37)];
[deleteButton setBackgroundImage:deleteImage forState:UIControlStateNormal];
[deleteButton addTarget:self action:@selector(deleteMag:) forControlEvents:UIControlEventTouchUpInside];
deleteButton.hidden=YES;
deleteButton.tag = 9;
//Progress bar
downloadProgress = [[UIProgressView alloc] initWithFrame:CGRectMake(100, 800, 127, 8)];
downloadPrecent = [[UILabel alloc]initWithFrame:CGRectMake(300, 800, 8, 8)];

dateMag.textColor = [UIColor blackColor];
downloadProgress.tag = 6;
downloadPrecent.tag = 7;
downloadProgress.hidden = YES;
downloadPrecent.hidden = YES;
//Add image subview
[view addSubview:romb];
//Label subview
[view addSubview:myLabel];

NSFileManager *fileManager = [NSFileManager defaultManager];

现在看起来像这样（别担心，它还在开发中:)） http://files.mail.ru/B2B41BA915624173B646184D4283D9F9?t=1
