我試圖使用UITableView列出特定進程的詳細信息。它在Xcode模擬器上運行時完美顯示。但是,在實際設備上部署時,它的格式不正確。令人費解的是,當我在Mac和iPhone上執行「ps aux」命令時,輸出的格式似乎是相同的。當在iPhone上部署「ps aux」命令輸出時格式不正確
這是怎麼看起來像在模擬器:
這是怎麼看起來像在實際設備上:
這裏是我的控制器代碼顯示這些視圖:
viewDidLoad:
NSLog(@"myString is :%@", myString);
int processID = [myString intValue];
NSTask *task;
task = [[NSTask alloc] init];
[task setLaunchPath: @"/bin/ps"];
arguments = [NSArray arrayWithObjects: @"aux", [NSString stringWithFormat:@"%i", processID],nil];
[task setArguments: arguments];
NSPipe *pipe;
pipe = [NSPipe pipe];
//[task setStandardOutput: pipe];
[task setStandardOutput:pipe];
NSFileHandle *file;
file = [pipe fileHandleForReading];
[task launch];
NSData *data;
data = [file readDataToEndOfFile];
NSString *string;
string = [[NSString alloc] initWithData: data
encoding: NSUTF8StringEncoding];
// NSLog(@"%@",string);
NSArray *lines= [string componentsSeparatedByString:@"\n"];
NSString *lastline = [lines objectAtIndex:[lines count]-2];
// NSLog(@"%@",lastline);
lines2= [lastline componentsSeparatedByString:@" "];
NSLog(@"%@",lines2);
for (int i=0; i<[lines2 count]; i++) {
if([[lines2 objectAtIndex:i] isEqualToString:@""]){
[lines2 removeObjectAtIndex:i];
}
}
for (int i=0; i<[lines2 count]; i++) {
if([[lines2 objectAtIndex:i] isEqualToString:@""]){
[lines2 removeObjectAtIndex:i];
}
}
NSLog(@"Lines 2 is%@",lines2);
NSLog(@"Status is %@",[lines2 objectAtIndex:7]);
self.title = @"Process Info";
label = [[NSMutableArray alloc]init];
[label addObject:@"User:"];
[label addObject:@"Process ID:"];
[label addObject:@"CPU(%):"];
[label addObject:@"MEM(%):"];
[label addObject:@"VSZ:"];
[label addObject:@"RSS:"];
[label addObject:@"TT:"];
[label addObject:@"STAT:"];
[label addObject:@"Time Started:"];
[label addObject:@"Time Elapsed:"];
[label addObject:@"Launch Command:"];
[super viewDidLoad];
的cellForRowAtIndexPath:
static NSString *CellIdentifier = @"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
}
[cell setSelectionStyle:UITableViewCellSelectionStyleNone];
NSString *cellValue = [label objectAtIndex:indexPath.row];
cell.textLabel.text = cellValue;
cell.textColor = [UIColor colorWithRed:154.0/255.0 green:14.0/255.0 blue:2.0/255.0 alpha:1];
cell.font = [UIFont systemFontOfSize:16.0];
UILabel *label2 = [[[UILabel alloc] initWithFrame:CGRectMake(120.0, 0, 240.0,
tableView.rowHeight)] autorelease];
label2.font = [UIFont systemFontOfSize:16.0];
NSString *cellValue1 = [lines2 objectAtIndex:indexPath.row];
label2.text = cellValue1;
label2.textAlignment = UITextAlignmentLeft;
label2.textColor = [UIColor blackColor];
label2.autoresizingMask = UIViewAutoresizingFlexibleRightMargin |
UIViewAutoresizingFlexibleHeight;
[cell.contentView addSubview:label2];
return cell;
numberOfRowsInSection:
return [label count];
的dealloc:
[myString release];
[arguments release];
//[lines2 release];
[ResultStringID release];
[values release];
[label release];
[super dealloc];
的 「PS AUX」 命令在Mac輸出:
「的ps aux」 命令對iPhone的輸出(通過SSH殼):
有點多餘的內容,首先在兩個平臺上發佈'ps aux'的輸出。 –
