NSHomeDirectory () Why return to the directory is / var / ....

The simulator is Users, but in the real machine into var, Why? Real machine is iOS6
Reply:
This is nothing strange, real machine directory structure with the desktop environment is not the same
Reply:
It returns, loaded containers of this package

Real machine is a mobile phone / iPad / ipod touch inside position. . .

Simulator is a computer location. . .

Apart from the beginning is not the same, but both are the same after half

IPhone3 simulator with stropng and UIwindow Why go wrong

Recent off-campus training IOS, put in the engine room simulator used IPhone5 Kaodao IPhone3 simulator code running back, there will be strong and UIwindow errors, etc., how to modify? New to understand, the Supreme explain.
Reply:
1 Check the next version. xcode whether it is supported by ARC version because strong statements are generally supported by ARC version (not used ARC, just know that the ARC have Strong, the underlying logic has __stong)

2. Equipment problem, because many of ios api, are available from ios4.0 began. Look at your device's system version. Recommends upgrading to 5.0, 6.0 to see the situation (because 6.0 is not suitable for beginners to learn, add a lot of api)

My custom cell's name is ComCell.xib, identifier for the ComCell

Then as you said, my code

static NSString * CellIdentifier = @ "ComCell";
ComCell * cell = [tableView dequeueReusableCellWithIdentifier: CellIdentifier];
if (cell == nil) {
cell = [[[ComCell alloc] initWithStyle: UITableViewCellStyleValue1 reuseIdentifier: CellIdentifier] autorelease];
}

However, did not show up?

My method:

static NSString * CellIdentifier = @ "ComCellIdentifier";
BOOL nibRegistered = NO;
if (! nibRegistered) {
UINib * nib = [UINib nibWithNibName: @ "Comcell" bundle: nil];
[TableView registerNib: nib forCellReuseIdentifier: CellIdentifier];
nibRegistered = YES;
}

ComCell * cell = [tableView dequeueReusableCellWithIdentifier: CellIdentifier];

Why always ComCell * cell = [tableView dequeueReusableCellWithIdentifier: CellIdentifier]; sentence

I do not XIB, direct code construct UI. . . . Background PNG images posted Zhang, facing tune coordinate wow

You above error is to say, can not you read in the default bundle hungry XIB file. . . NIB is XIB.

bundle is your app built path

The company said without considering compatibility, so we do not xib, and directly in the storyboard to write

But would like to ask, where is that NibName defined?

NibName is the file name? Let's say MyNib.xib it NibName is not that MyNib?

html ios layout layout also seems more than strange!

I storyboard in uitableviewcell added a view

How to set its height?

Why my settings
CGRect transmitViewBounds = CGRectMake (0, 0, 270, 100);
[Cell.subView setBounds: transmitViewBounds];

In just loaded does not work, but then included in the draw when there is effect, but the effect is randomly appear in a cell on

Is how else ah?
