Is AppKit causing you frustration? Instead of just complaining about it, lets try to make it better by compiling a list of specific problems with AppKit. Leave a comment below, and I'll include it in the list.

---

##NSView##

• NSView does not have the ability to set an affine transform (rdar://15608609)
• Controls that have cells (such as NSTextField) do not respond properly when layer-backed. Take NSButton as an example. When not layer-backed, it will animate properly using the animator proxy. When layer-backed, using the animator proxy breaks focus rings (they jump to destination immediately). Currently, directly manipulating the layer of a cell-based control is not supported (and will lead to a broken interface), but is much needed. (rdar://15608822)

##NSViewController##

• NSViewController could be more useful. It has -loadView but no other lifecycle methods. (rdar://15608948)

self.startButton.rac_command = [RACCommand command];
self.stopButton.rac_command = [RACCommand command];

__unsafe_unretained id weakSelf = self;
id<RACSignal> tick = [[[[self.startButton.rac_command
    map:^(id _) {
        RTAFirstView *strongSelf = weakSelf;
        // Map each start button click to a new signal that fires every second
        // and stops when the stop button is clicked.
        return [[RACSignal interval:1] takeUntil:strongSelf.stopButton.rac_command];

self.startButton.rac_command = [RACCommand command];
self.stopButton.rac_command = [RACCommand command];
self.resetButton.rac_command = [RACCommand command];

static const CGFloat interval = 0.01;
__unsafe_unretained id weakSelf = self;
// Signal id -> Signal Signal Number
// Map each click of the start button to a signal that fires at our interval
// and stops when the stop button's clicked.
id<RACSignal> start = [self.startButton.rac_command map:^(id _) {

NSAttributedString *attr = [[NSAttributedString alloc] initWithString:text attributes:yourAttrDictHere];

Let's say you have an iOS project, and you want to use some external library, like AFNetworking. How do you integrate it?

With submodules

Add the project to your repo:

git submodule add [email protected]:AFNetworking/AFNetworking.git Vendor/AFNetworking

or something to that effect.

-- Firstly, remove PRIMARY KEY attribute of former PRIMARY KEY
ALTER TABLE <table_name> DROP CONSTRAINT <table_name>_pkey;

-- Then change column name of  your PRIMARY KEY and PRIMARY KEY candidates properly.
ALTER TABLE <table_name> RENAME COLUMN <primary_key_candidate> TO id;
