You are trying to set the frame of an NSString - something that doesn't exist. self.tvContent is an NSString, not a UILabel as you seem to have suspected.
This is a good chance to learn how to read exceptions. I'll break it down for you here:

libc++abi.dylib: terminate called throwing an exception
Here's what you are interested in:
-[__NSCFString setFrame:]: unrecognized selector sent to instance 0x7894c00
The system is giving you the class of the object and the message you tried to send it - in this case an NSString that you tried to call setFrame: on.
This information coupled with that you know which line is crashing makes for an easy conclusion: self.tvContent is an NSString where you were probably expecting a UILabel.
-[__NSCFString setFrame:]
Your app thinks that tvContent is a string, not a view. Make sure your outlet is connected to your UI correctly. Additionally, if you have a property for tvContent, it needs to be an owning reference (eg strong (under ARC) or retain (non-ARC)).

I've created a XIB containing only a UITableView. I changed the parameters of the project to load this view at launch. But I get this "unrecognized selector sent to instance" error I don't know what it is. How do I fix this and get my app to show my view ?
I've searched the web and it seems that might come from Objective-C libraries ?
EDIT
I did some testing, it's look like it crashes when I link my TableView with my IBOutlet in the ViewController. Am I doing something wrong with the type TableView ?
The viewcontroller :
class Liste: UIViewController {
#IBOutlet weak var maListe: UITableView!
override func viewDidLoad() {
super.viewDidLoad()
}
}
The error stack :

It looks like, you might have created IBOutlet or IBAction and deleted later in the code. Revisit the connections in the storyboard connection inspectors and check if there is any warning symbol like the attached screenshot, then you need to remove that connection.
Or if you can share your code I can look into.

I have many [NSArray objectAtIndex], I don't know which one makes it crash.
I've writen the debug code below, but still can't catch it. It's in a UITableView, I load more and more cells by pull down the table, then it sometimes crashes.
#import "NSArray+Debug.h"
#import "MLTool.h"
#implementation NSArray (Debug)
- (id)objectAtIndexEx:(NSUInteger)index{
if (self.count<1) {
assert(0);
}
NSString *str=[NSString stringWithFormat:#"count=%d,index=%d,info=%#",self.count,index,[self objectAtIndex:index]];
if ([MLTool isEmptyString:str]
// ||str==
) {
assert(0);
}
NSLogUTF8(#"break:%#",str);
return [self objectAtIndex:index];
}
#end
You can add an "exception breakpoint" in xcode to stop your debugging at the moment of the crash and check why it will crash.
For that in the section breakpoint/debug of the left navigator you can tap on the "+" at the bottom-left corner to add an "Exception breakpoint".
I realize this error has been discussed many times on stackoverflow, but I'm still not sure what I'm missing. Here's the console output:
Unknown class CRBarGraphController in Interface Builder file.
2014-11-18 18:40:05.796 Test[7319:60b] -[UIImageView start2]: unrecognized selector sent to instance 0x16562ac0
2014-11-18 18:40:06.256 Test[7319:60b] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[UIImageView start2]: unrecognized selector sent to instance 0x16562ac0'
CRBarGraphController.m defines a function (void)start2; also declared in the interface for CRBarGraphController.h.
start2 is called from CRGraphViewController.m using the following code:
-(void)viewWillAppear:(BOOL)animated {
self.navigationController.navigationBarHidden = NO;
[self.bar_Graph start2];
}
where, bar_Graph is an object of CRBarGraphController, declared in CRGraphViewController.h as:
#property (weak, nonatomic) IBOutlet CRBarGraphController *bar_Graph;
CRGraphViewController.h does import CRBarGraphController.h
Also, in the storyboard, bar_Graph outlet is set to class, CRBarGraphController.
Why does XCode still think bar_Graph is an instance of UIImageView and not CRBarGraphComtroller? I included an exception breakpoint to make sure the exception originates from where start2 is being called.
I have a method to compare 2 objects:
- (NSComparisonResult)compare:(NSObject *)object1 to:(NSObject *)object2{
// do some stuff
return NSOrderedSame; // or NSOrderedAscending or NSOrderedDescending
}
This method gets called like this:
NSArray *sortedSyncedAufgaben = [syncedAufgabe sortedArrayUsingSelector:#selector(compare:to:)];
Now, when I run this on my iPhone, a "unrecognized selector error" is thrown in the line with the selector:
* Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[ImpfVorgang compare:to:]: unrecognized selector sent to instance 0x14ebf040'
What is wrong? I thought for each parameter I need a colon?
sortedArrayUsingSelector: tries to apply you selector to the object on the left-hand side of the comparison, not to the class that calls sortedArrayUsingSelector:. In other words, if the selector exists in your class that initiates the sort, not in the class of the object inside NSArray (i.e. not in your ImpfVorgang class), you are going to see an "unrecognized selector error".
You can change your code to apply the selector manually, like this:
NSArray * sortedSyncedAufgaben = [syncedAufgabe sortedArrayUsingComparator:^(NSObject *a, NSObject* b) {
return [self compare:a to:b];
}];
Alternatively, you could move the comparison logic into the comparator block, and drop the compare:to: method altogether.
