完全一樣，你（應(yīng)該）已經(jīng)這樣做了：
+ (instancetype)sharedInstance{
static MyClass *sharedInstance = nil;
static dispatch_once_t onceToken;
dispatch_once(&onceToken, ^{
sharedInstance = [[MyClass alloc] init];
// Do any other initialisation stuff here
});
return sharedInstance;}

如果你想根據(jù)需要創(chuàng)建其他實(shí)例。這個：
+ (MyClass *)sharedInstance{
static MyClass *sharedInstance = nil;
static dispatch_once_t onceToken;
dispatch_once(&onceToken, ^{
sharedInstance = [[MyClass alloc] init];
// Do any other initialisation stuff here
});
return sharedInstance;}否則，你應(yīng)該這樣做：
+ (id)allocWithZone:(NSZone *)zone{
static MyClass *sharedInstance = nil;
static dispatch_once_t onceToken;
dispatch_once(&onceToken, ^{
sharedInstance = [super allocWithZone:zone];
});
return sharedInstance;}

如何使用：
MySingletonClass.h
@interface MySingletonClass : NSObject+(MySingletonClass *)sharedInstance;@end
MySingletonClass.m
#import "MySingletonClass.h"#import "SynthesizeSingleton.h"@implementation MySingletonClassSYNTHESIZE_SINGLETON_FOR_CLASS(MySingletonClass)@end
