  • Is it possible to recreate User Gestures in iPhone?

    - by MadhavanRP
    I am developing an app and I have encountered a problem that comes down to this scenario: Consider a superview with two buttons(button1,button2) and a text view, all as its subviews. When I click on one button, I display the text view. When I tap on anywhere outside the textview, but in the super view, I need to dismiss the text view. I have added a UITapGestureRecognizer to the super view and it calls a method tap:. In tap:, I get the point of the tap and if it is outside the text view, I dismiss the text view and remove the GestureRecognizer. Now the problem occurs when I tap on button 2. I need to dismiss the text view as well as execute the action for button 2. But it enters tap: and I do not wish to call the button 2's method from there. What I want to know is if it would be possible to emulate the same tap at the same co ordinates after the gesture recognizer is removed? If not what is the way I proceed to solve this issue?

  • Effect of 'myObj = [[[[MyClass alloc] init] autorelease] retain];'?

    - by filipe
    I've just downloaded the Facebook iOS SDK and I noticed that in the sample code that comes with the SDK whenever it creates an instance of the Facebook class it does it like this: _facebook = [[[[Facebook alloc] init] autorelease] retain]; where _facebook is a member variable of the calling object (i.e. not a local variable). Can anyone explain exactly what's the point of autoreleasing and then retaining it?

  • Which Ipod touch generation should I buy? 2nd or 3rd?

    - by kukabunga
    I want to create games for Iphone/Ipod touch. Unfortunately I don't have a lot of money so I can buy only one device. Ipod is cheaper than Iphone, so I decided to bought Ipod touch. But I am afraid of buying 3rd generation - because it has more memory, more faster CPU, etc. And I think if I post my app on appstore - people with 2nd generation Ipod might have trouble with my app (because I was testing it on 3rd generation). But on the other hand - I am planning to create 3d/cpu demanding game - and it would be easy for me to implement it on device with more calculation power... What should I do in this situation? Any advice is appreciate.

  • Using setters On Int?

    - by fuzzygoat
    Just curious, given: unsigned int pulseCounter_001; @property(nonatomic, assign)unsigned int pulseCounter_001; @synthesize pulseCounter_001; Is there any reason to use: [self setPulseCounter_001:0]; Or just use: pulseCounter_001 = 0; Style wise I think the latter says "we are setting an int" better, just curious as to any overheads involved in each? gary

  • Creating a "permanent" Cocoa object

    - by quixoto
    I have an object factory that hands out instances of certain "constant" objects. I'd like these objects to be protected against bad memory management by clients. This is how I've overridden the class's key methods. Am I missing anything (code or other considerations)? - (id)retain { return self; } - (NSUInteger)retainCount { return UINT_MAX; } - (void)release { // nothing. }

  • UIImageView Centering Problem.

    - by sagar
    To understand my problem let's follow this steps. Open - XCode - New Project - View based application. Open View Controller.xib file. Drag an image-view into viewController's view. Place that image view on center of viewController's view. Apply size of 125x125 to image-view. Take any image with dimension of 320 width & 460 height. Drag that image into your application resources directory. Now, Again back to .xib File & select image-view Set image (which is in your resources) to image-view Set Image-view Mode to - Center Ok. Let me explain the situation now. after performing all above steps - image-view has an image which is larger than image-view's size. However, Image-view places that image on center & in View controller image-view is looking proper ( not scaled ). But When you run your application, image-view will be displayed in size of 320x460. ( but it is not actually scaled. ) Now, I can't find the reason, why interface builder is displaying something else & simulator/iphone is displaying something else ? My Query. I want the image's center portion within image-view no matter what image size is. Thanks in advance for sharing your knowledge. Sagar.

  • Sorting NSTableColumn contents

    - by Yahoo
    Hey, I have a problem with sorting NSTableColumn contents. In my NSTableView there are three columns: File, Size, Path. The contents are stored in NSMutableArray. Each object in this array is a NSDictionary containing three keys: file, size and path - value for each is a NSString. In Interface Builder, in each Table Column's attributes I can choose sorting options: Selector: IB entered "compare:" which I think is ok, because I compare NSStrings. Sort Key - and that's the problem I think - I don't know what to enter here. Any clues? If you've got questions about my code, please ask.
