今天遇到一个奇怪的问题，使用NSOperationQueue连续添加多个子线程时出现子线程不执行的问题。解决方法如下：

在连续的打开多个子线程时，设置一定的时间间隔。    [NSThread sleepForTimeInterval:0.1];

 

    NSInvocationOperation * theOp = [[NSInvocationOperation alloc] initWithTarget:self selector:@selector(getDetailProfile:) object:(void *)0];

    [[Func appOperationQueue] addOperation:theOp];

    [theOp release];

    

    [NSThread sleepForTimeInterval:0.1]; //不能省略此处代码。联系添加多线程时，应设置一定时间间隔

    

    NSInvocationOperation * theOp1 = [[NSInvocationOperation alloc] initWithTarget:self selector:@selector(getDetailProfile:) object:(void *)1];

    [[Func appOperationQueue] addOperation:theOp1];

    [theOp1 release];

    

    [NSThread sleepForTimeInterval:0.1];//不能省略此处代码。联系添加多线程时，应设置一定时间间隔

    NSInvocationOperation * theOp2 = [[NSInvocationOperation alloc] initWithTarget:self selector:@selector(getDetailProfile:) object:(void *)2];

    [[Func appOperationQueue] addOperation:theOp2];

    [theOp2 release];

    

    [NSThread sleepForTimeInterval:0.1];//不能省略此处代码。联系添加多线程时，应设置一定时间间隔

    

    NSInvocationOperation * theOp3 = [[NSInvocationOperation alloc] initWithTarget:self selector:@selector(getDetailProfile:) object:(void *)3];

    [[Func appOperationQueue] addOperation:theOp3];

    [theOp3 release];

    

    [NSThread sleepForTimeInterval:0.1];//不能省略此处代码。联系添加多线程时，应设置一定时间间隔

    

    NSInvocationOperation * theOp4 = [[NSInvocationOperation alloc] initWithTarget:self selector:@selector(getDetailProfile:) object:(void *)4];

    [[Func appOperationQueue] addOperation:theOp4];

    [theOp4 release];
