我有这个
- (void)loadView {
BOOL success;
NSFileManager *fileManager = [NSFileManager defaultManager];
NSString* documentsPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];
NSString* databasePath = [documentsPath stringByAppendingPathComponent:@"ProxDeals.db"];
NSError *error;
BOOL fileExists = [[NSFileManager defaultManager] fileExistsAtPath:databasePath];
if (fileExists==TRUE) {
[[NSBundle mainBundle] loadNibNamed:@"ProxDealsViewController" owner:self options:nil];
}
else {
NSString *defaultDBPath = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:@"ProxDeals.db"];
NSLog(@"%@",defaultDBPath);
success = [fileManager copyItemAtPath:defaultDBPath toPath:databasePath error:&error];
if (!success) {
NSAssert1(0, @"Failed to create writable database file with message '%@/.", [error localizedDescription]);
}
[[NSBundle mainBundle] loadNibNamed:@"UserRegistration" owner:self options:nil];
}
}
而这个错误: …
编辑:我的问题是因为plist文件已损坏.所以,如果你有同样的问题,可能是因为你的plist文件中有些东西.
所以我有这个应用程序,一切正常,直到我将我的设备更新到IOS 6.之后,我无法在设备上安装该应用程序.该应用程序在IOS 5.0模拟器和IOS 6.0模拟器上运行良好.当我尝试为设备构建它时,启动屏幕会显示两秒钟,然后应用程序关闭.在Xcode中我收到此错误:
timed out waiting for app to launch
我搜索了网页,它说这是一个AdHoc配置问题,但我的配置文件是有序的.我甚至更改了应用程序ID并删除了旧的配置,我得到了同样的错误.
在设备控制台中,我收到这个奇怪的错误:

我有这个简单的代码:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
static NSString *CellIdentifier = @"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
cell.accessoryType=UITableViewCellAccessoryDetailDisclosureButton;
}
// Configure the cell...
NSString *subtitle = [NSString stringWithString: @"All about the color "];
cell.detailTextLabel.text=subtitle;
cell.textLabel.text = [authorList objectAtIndex: [indexPath row]];
return cell;
}
问题是我的副标题没有出现.我做错了什么.请帮忙.谢谢.
所以我有这段代码创建一个自定义UISlider.它工作正常,直到IOS 6.在IOS 6中,图像不显示,它显示默认滑块.有人可以解释为什么会这样吗？
[sliderFPS setMinimumTrackImage:[[UIImage imageNamed:@"camera_slider_empty.png"] stretchableImageWithLeftCapWidth:8 topCapHeight:0]
forState:UIControlStateNormal];
[sliderFPS setMaximumTrackImage:[[UIImage imageNamed:@"camera_slider_full.png"] stretchableImageWithLeftCapWidth:8 topCapHeight:0]
forState:UIControlStateNormal];
[sliderFPS setThumbImage:[UIImage imageNamed:@"camera_fps_slider_button"]
forState:UIControlStateNormal];
我在UIScrollView中有很多按钮,我试图在按钮点击上获得他们的位置.这是我的代码:
UIScrollView *scrollView = [[UIScrollView alloc] initWithFrame:CGRectMake(2, 0, 262, 748)];
scrollView.contentSize=CGSizeMake(262, 816);
scrollView.bounces=NO;
scrollView.delaysContentTouches=YES;
buton1 = [[UIButton buttonWithType:UIButtonTypeCustom] retain];
buton1.frame = CGRectMake(2, 0, 262, 102);
buton1.bounds = CGRectMake(2, 0, 262.0, 102.0);
[buton1 setTag:1];
[buton1 setImage:[UIImage imageNamed:@"left_gride.png"] forState:UIControlStateNormal];
[buton1 addTarget:self action:@selector(buttonClick:) forControlEvents:UIControlEventTouchUpInside];
[scrollView addSubview:buton1];
和
-(void) buttonClick:(UIButton*)button{
if ([button tag]==1)
{
NSLog(@"position:%d",buton1.frame.origin.x);
}
else
{
NSLog(@"position:%d",buton2.frame.origin.y);
}
}
我的代码有什么问题.谢谢.
我也尝试过:
-(void) buttonClick:(UIButton*)button{
if ([button tag]==1)
{
NSLog(@"position:%d",buton1.frame.origin.x);
}
else
{
NSLog(@"position:%d",buton2.frame.origin.y);
}
-(void) buttonClick:(UIButton*)button{
if ([button tag]==1)
{
NSLog(@"position:%d",button.frame.origin.x);
}
else …这个查询有什么问题？
$query3 = "INSERT INTO Users
