I am trying to show the User different Phone Numbers on Apple Watch and he clicks on one than phone call alert should appear. I'll do it like this but the Alert is just dismissed without call action:
NSMutableArray *tempArray = [[NSMutableArray alloc] initWithCapacity:0];
WKExtension *myExt = [WKExtension sharedExtension];
for (NSString *phone in arr) {
NSString *tel = [NSString stringWithFormat:#"tel:%#",phone];
WKAlertAction *act = [WKAlertAction actionWithTitle:tel style:WKAlertActionStyleDefault handler:^(void){
[myExt openSystemURL:[NSURL URLWithString:phone1]];
}];
[tempArray addObject:act];
}
NSString *titleMessage = #"Call";
NSString *textMessage = #"Please select the number you want to call.";
NSString *cancel = #"Cancel";
WKAlertAction *act = [WKAlertAction actionWithTitle:cancel style:WKAlertActionStyleDestructive handler:^(void){
}];
[tempArray addObject:act];
[self presentAlertControllerWithTitle:titleMessage message:textMessage preferredStyle:WKAlertControllerStyleAlert actions:tempArray];
Buttons are shown as expected and the Handler is also called with the correct Phone Number. But it does not openSystemURL. Does somebody know why and how to fix? Thanks!
I think you forgot to add "tel" scheme ,Use below code :
[WKAlertAction actionWithTitle:#"tel" style:WKAlertActionStyleDefault handler:^(void){
[[WKExtension sharedExtension]openSystemURL:[NSURL URLWithString:[NSString stringWithFormat:#"tel:%#",#"YOUR NUMBER"]]];
}];

I have a NSTableView which I dynamically add columns. I've just added a call to setDataCell to customize my cell. The code looks like:
for(NSUInteger columnIndex = 0; columnIndex < resultSet.columNames.count; ++columnIndex)
{
NSTableColumn * newColumn = [[NSTableColumn alloc] initWithIdentifier: [NSString stringWithFormat: #"%ld", columnIndex]];
[newColumn.headerCell setAlignment: NSCenterTextAlignment];
[newColumn.headerCell setStringValue: resultSet.columNames[columnIndex]];
[newColumn setDataCell: [[HSDisclosureTextFieldCell alloc] init]];
[newColumn setEditable: YES];
[resultsTableView addTableColumn: newColumn];
if(newColumn.width < 60) [newColumn sizeToFit];
} // End of column loop
If I remove the call to setDataCell then I can still double click my entry and edit it.
I have minimized the HSDisclosureTextFieldCell contains the following (no overrides):
#interface HSDisclosureTextFieldCell : NSTextFieldCell
{
}
But I still cannot double click to edit the field anymore.
Any ideas where I'm going wrong?
Turns out even though I am doing:
[newColumn setEditable: YES];
and have:
- (BOOL)tableView:(NSTableView *)tableView shouldEditTableColumn:(NSTableColumn *)tableColumn row:(NSInteger)row
implemented, I needed to switch my setDataCell to be:
HSDisclosureTextFieldCell * cell = [[HSDisclosureTextFieldCell alloc] init];
[cell setEditable: YES];
[newColumn setDataCell: cell];
Now that I have done that, everything seems to be working properly.
I need re-encoding a video file from photo library for web site service.
I tried below code but it has occurred error like 'video composition must have composition instructions'.
(code)
AVAsset *anAsset = [[AVURLAsset alloc] initWithURL:videoFileUrl options:nil];
NSArray *compatiblePresets = [AVAssetExportSession exportPresetsCompatibleWithAsset:anAsset];
if ([compatiblePresets containsObject:AVAssetExportPresetMediumQuality]) {
self.exportSession = [[AVAssetExportSession alloc]
initWithAsset:anAsset presetName:AVAssetExportPresetPassthrough];
AVMutableComposition* mixComposition = [[AVMutableComposition alloc] init];
AVMutableCompositionTrack *firstTrack = [mixComposition addMutableTrackWithMediaType:AVMediaTypeVideo preferredTrackID:kCMPersistentTrackID_Invalid];
[firstTrack insertTimeRange:CMTimeRangeMake(kCMTimeZero, anAsset.duration) ofTrack:[[anAsset tracksWithMediaType:AVMediaTypeVideo] objectAtIndex:0] atTime:kCMTimeZero error:nil];
AVMutableVideoCompositionLayerInstruction *FirstlayerInstruction = [AVMutableVideoCompositionLayerInstruction videoCompositionLayerInstructionWithAssetTrack:firstTrack];
AVMutableVideoCompositionInstruction * MainInstruction = [AVMutableVideoCompositionInstruction videoCompositionInstruction];
MainInstruction.layerInstructions = [NSArray arrayWithObjects:FirstlayerInstruction,nil];
AVMutableVideoComposition *MainCompositionInst = [AVMutableVideoComposition videoComposition];
MainCompositionInst.frameDuration = CMTimeMake(1, 30); // bit rate
MainCompositionInst.renderSize = CGSizeMake(640, 480); // frame rate
[self.exportSession setVideoComposition:MainCompositionInst];
NSURL *furl = [NSURL fileURLWithPath:self.tmpVideoPath];
self.exportSession.outputURL = furl;
self.exportSession.outputFileType = AVFileTypeQuickTimeMovie;
CMTime start = CMTimeMakeWithSeconds(self.startTime, anAsset.duration.timescale);
CMTime duration = CMTimeMakeWithSeconds(self.stopTime-self.startTime, anAsset.duration.timescale);
CMTimeRange range = CMTimeRangeMake(start, duration);
self.exportSession.timeRange = range;
self.trimBtn.hidden = YES;
self.myActivityIndicator.hidden = NO;
[self.myActivityIndicator startAnimating];
[self.exportSession exportAsynchronouslyWithCompletionHandler:^{
switch ([self.exportSession status]) {
case AVAssetExportSessionStatusFailed:
NSLog(#"Export failed: %#", [[self.exportSession error] localizedDescription]);
break;
case AVAssetExportSessionStatusCancelled:
NSLog(#"Export canceled");
break;
default:
NSLog(#"NONE");
dispatch_async(dispatch_get_main_queue(), ^{
[self.myActivityIndicator stopAnimating];
self.myActivityIndicator.hidden = YES;
self.trimBtn.hidden = NO;
[self playMovie:self.tmpVideoPath];
});
break;
}
}];
}
}
without the changing frame rate and bit rate, it works perfectly.
Please give me any advise.
Thanks.
Framerate I'm still looking for, but bitrate has been solved by this drop in replacement for AVAssetExportSession: https://github.com/rs/SDAVAssetExportSession
Not sure but some things to look at. Unfortunatley the error messages dont tell you much in these cases in AVFoundation.
In general, I would make things simple and slowly add functionality.To start, make sure all layers start at zero and then end at the final duration. Do the same for the main composition. Invalid times may give you an error like this. For your instruction, make sure that it starts at the same time and ends at the same time too.
Ok, so I would like to create an NSDictionary, but the pointer should be followed by the value of an NSString that has been put in by the user. Is this possible? I imagine it would be something along the lines of this...
someNSString = _someTextField.text;
NSDictionary * {someNSString} = [NSDictionary dictionaryWithObjectsAndKeys:
[NSNumber numberWithInt:someUnimportantVariable], #"someUnimportantKey",...nil]
Thanks in advance, I realize that this is either completely not possible or there is a pretty simple solution. Either way, I'm sorry if I wasted your time.
you could try creating a "dictionary of dictionaries". something to the effect of:
someNSString = _someTextField.text;
NSDictionary *myDictionary = [[NSDictionary alloc] init];
[myDictionary setObject:[NSDictionary dictionaryWithObjectsAndKeys: [NSNumber numberWithInt:someUnimportantVariable], #"someUnimportantKey",...nil] forKey:someNSString];
and if you wanted to get back that dictionary
NSDictionary someNSStringDictionary = [myDictionary objectForKey:someNSString];
let me know if it helps in any way.
I am new to Objective-C and I have researched this online for weeks now. Almost every example is the same on every site and does not fully make it clear to me how to integrate it into my code for an Xcode 4 App.
The example seen everywhere is:
NSEnumerator* theEnum = [some_array objectEnumerator];
id obj; or id some_object = NULL;
while(obj = [theEnum nextObject]) {
//do something...
I think if I better understood what id some_object = NULL;/ id obj; represents I could figure it out on my own.
In my code I have three arrays. I want to be able to display one object in each array in a UILabel field every time the user clicks the Next button until all of them have been displayed.
NSArray1 = 1,2,3
NSArray2 = John, Jill, Josh
NSArray3 = boy, girl, boy
When the next button is pushed you would see 1, John and boy. The next time you would see 2, Jill and girl and finally 3, Josh and boy.
Below is basic example, not my actually code.
number = [[NSArray alloc] initWithObjects:#"1",#"2",#"3", nil];
name = [[NSArray alloc] initWithObjects:#"John",#"Jill",#"Josh", nil];
gender = [[NSArray alloc] initWithObjects:#"boy",#"girl",#"boy", nil];
NSEnumerator *enum = [number objectEnumerator];
id obj; (??What is this?? And how to connect to the statement below??)
while ((obj = [enumNumber nextObject])) {
self.numberItem.text = ??
self.nameItem.text = ??
self.genderItem.text = ??
Thanks
id obj is just the variable containing the current variable you're looking at. In this code, since your NSArrays all contain string, you could use NSString *obj instead.
An enumerator can only enumerate one collection at a time. If you want to loop through all three of them together, use a traditional for loop:
for(unsigned int i = 0; i < number.count; i++) {
self.numberItem.text = [number objectAtIndex:i];
self.nameItem.text = [name objectAtIndex:i];
self.genderItem.text = [gender objectAtIndex:i];
}
I am inserting an NSAttributedString into an NSTableView, and depending on it's content I am adding attributes to its style dictionary.
- (id)tableView:(NSTableView *)aTableView objectValueForTableColumn:(NSTableColumn *)aTableColumn row:(NSInteger)rowIndex {
NSAttributedString *theValue;
NSMutableDictionary *attributes = [[NSMutableDictionary alloc] init];
[attributes setObject:[NSFont systemFontOfSize:11] forKey:NSFontAttributeName];
currentObject = [ticketsDataSource objectAtIndex:rowIndex];
if ([[currentObject valueForKey:aTableColumn.identifier] isKindOfClass:([NSString class])]) {
NSString *currentValue = [currentObject valueForKey:aTableColumn.identifier];
if ([currentValue isEqualToString:#"resolved"]) {
[attributes setObject:[NSColor colorWithCalibratedRed:0.344 green:0.619 blue:0.000 alpha:1.000] forKey:NSForegroundColorAttributeName];
}
if ([previousValue isEqualToString:#"resolved"]) {
[attributes setObject:[NSNumber numberWithInteger:NSUnderlinePatternSolid | NSUnderlineStyleSingle] forKey:NSStrikethroughStyleAttributeName];
}
theValue = [[NSAttributedString alloc] initWithString:currentValue attributes:attributes];
previousValue = currentValue;
}
As you can see, basically what happens is when it writes a string called "resolved" it knows that the very next column, which is the title column, gets a strikethrough. It works just fine, but for whatever reason, the strikethrough is not drawing over the entirety of the text!

Yet another weirdness with layer-backing. So I turned it off :(
